Why Outdoor Saunas Are the Ultimate High-Performance Investment in Austin
Austin doesn't do average. We do high-performance. For the local tech and VC crowd, outdoor saunas are the new executive priority. This isn't about a luxury amenity. It's about a strategic recovery asset parked right in your backyard. By 2026, the standard for a high-end residence has shifted. The backyard circuit is the new benchmark, combining heat, cold, and architectural precision to create a private recovery hub.
The science is clear and the results are measurable. Regular heat exposure triggers heat shock proteins. These proteins repair damaged cellular structures and improve longevity. It's a direct counter-attack against high-cortisol environments. If you're looking for a deeper dive into the history and mechanics of what is a sauna?, the fundamental principles remain the same, but the execution has evolved. We're building for biological optimization.
The Austin wellness trend: why now?
Local fitness culture is moving away from crowded public spaces. High-performance professionals want a 24/7 sanctuary. They want total control over their recovery environment. We're seeing a rise in social wellness design in Central Texas. This means the sauna is a focal point for networking and family time, not a hidden box. It's about privacy and convenience. You don't waste time commuting to a spa when the best facility in the city is ten feet from your back door.
Impact on residential property value
Professional outdoor saunas drive serious ROI in the Austin real estate market. Integrated units consistently outperform standalone DIY kits in long-term appraisal value. A 2024 market analysis showed that high-end homes with integrated wellness features sell 12% faster than those without. Future buyers in the luxury bracket aren't looking for projects. They want turnkey recovery suites. A well-executed sauna provides a wow factor that differentiates a property in a competitive market. It’s an investment in your health now and your equity later.
Building these structures requires more than just a heater and some cedar. It takes an understanding of local climate demands and architectural integration. We don't just drop a box on a patio. We build high-performance tools that stand up to the Texas sun and deliver consistent results every single session. Quality construction ensures your investment doesn't just look good on day one, but continues to perform for a decade.
Material Science: Why Thermally Modified Wood Wins in the Texas Heat
Austin weather is a gear-killer. We face 100-plus degree days for months at a time, followed by rapid humidity spikes that reach 90 percent. This cycle wrecks standard lumber. While traditional cedar is a classic choice, it often fails under the modern high-heat stress of Central Texas. You need a material that won't warp when the sun beats down on your recovery suite.
Thermally modified wood, specifically Thermory, is the gold standard for 2026. The process is intense. Technicians heat the wood to over 400 degrees Fahrenheit in a vacuum. This cooks out the natural sugars and resins that attract rot and insects. It leaves you with a dimensionally stable product. It won't swell in the rain or shrink in the drought.
Cedar vs. Thermory: The No-BS Comparison
Cedar is soft. It smells great, but it requires re-oiling every six months to fight UV damage in Austin. Thermory is a 30-year investment. It offers superior thermal conductivity, meaning it stays cooler to the touch even at high internal temperatures. This is vital for maximizing the cardiovascular health benefits of saunas. You want the heat in the air, not burning your skin on the bench. Thermory requires significantly less maintenance, usually needing a UV-protective coat only once every two years.
Insulation and Vapor Barriers
Many outdoor saunas in Austin are thin-walled barrels. These are built with 1.5-inch staves that struggle to fight 105-degree external temperatures. They are inefficient and leak heat. A high-performance build utilizes multi-layer wall construction. This includes a dedicated vapor barrier to stop internal condensation from rotting the structure from the inside out.
Real performance requires hitting a consistent 190°F. To achieve this in the Texas sun, you need a rainscreen, a vapor barrier, and high-density insulation. This setup keeps the heat in and the humidity out. If you are planning a serious build, look at how professional design-build teams engineer these structural layers for longevity.
High-performance recovery is about precision. You can't get that precision from a kit that warps after one season. Invest in the material science that handles the Austin climate. It's the difference between a functional tool and a backyard eyesore.
Comparing Sauna Architectures: Barrels, Cabins, and Custom Integrations
Selecting the right structure for your outdoor sauna is a performance decision. The geometry of the unit dictates how heat moves, how many people you can fit, and how the wood survives the brutal Central Texas sun. You aren't just buying a box of cedar. You're investing in a thermal environment that needs to deliver consistent results every time you step inside.
Three primary formats dominate the Austin market. Each offers a distinct trade-off between heat-up speed, interior volume, and architectural integration. Whether you want a plug-and-play solution or a permanent structural addition, understanding these mechanics is the first step toward a successful build.
The Barrel Sauna: Pros and Cons for Austin
The barrel is the iconic choice for high-performance recovery. Its circular design eliminates corners where air pockets stagnate, promoting constant heat convection. This allows your unit to hit 175 degrees significantly faster than a square cabin of the same size. It's a strategic win for owners who value efficiency and want a smaller footprint on their property.
Standard barrel designs often face the "cold feet" problem. Because heat rises to the top of the curve, the floor remains cool. High-end models solve this with recessed floors or multi-level benches that get your feet above the heater. In Austin, skip the dirt or grass. Site your barrel on limestone pavers or a reinforced wood platform. This prevents moisture rot and ensures the structural rings stay aligned as the wood expands and contracts.
Cabin and Cube Designs: The Modern Aesthetic
Modern "Cube" designs are currently the standard for high-end builds in Westlake and Tarrytown. These structures prioritize floor-to-ceiling glass walls, making them a strategic choice for properties with Hill Country views. Unlike the tight quarters of a barrel, cabin designs offer superior insulation and vertical space. This allows for multi-level seating where users can choose their heat intensity by shifting levels.
A standard 6x8 foot cabin provides roughly 30% more usable interior volume than a barrel with the same footprint. This extra space is essential for group sessions or "sauna yoga." The flat roof lines also allow for easier integration of high-powered electric heaters that require specific clearances. It's a bold, architectural statement that mimics the clean lines of modern Austin residential design.
Custom Built-ins: Seamless Integration
Custom built-ins represent the ultimate play for homeowners who want their outdoor saunas to feel like a permanent part of the estate. These units are often embedded directly into existing decks or carved into limestone hillsides. This approach maximizes every square inch of your property and creates a seamless transition from the pool to the recovery zone.
Building custom requires precise engineering for ventilation and drainage. You're essentially building a small, high-heat room that must breathe. When executed correctly, a custom-integrated sauna acts as a structural anchor for your outdoor living space. It moves beyond a portable product and becomes a permanent architectural feature that drives long-term property value.
Siting and Engineering Your Austin Sauna for Longevity and Privacy
Don't just drop your unit on the grass and hope for the best. Austin’s soil shifts, and your neighbors have eyes. You need a strategic layout that maximizes heat retention and minimizes social friction. High-performance outdoor saunas require more than a level surface; they require an engineered environment that handles Central Texas weather and neighborhood politics.
Electrical power is your first hurdle. A standard 110V outlet won't cut it for a serious heat cycle. You need a dedicated 240V circuit with a 40 to 60-amp breaker. This ensures your heater reaches 190 degrees in under 40 minutes, even during a February cold snap. Without this dedicated line, you're just sitting in a lukewarm room wasting time.
Foundation engineering is equally critical. Austin sits on a volatile mix of limestone and expansive clay. A reinforced concrete pad or a heavy-duty gravel base with a timber frame prevents the structure from racking as the ground swells. Proper drainage ensures water moves away from the base, preventing rot and keeping the wood stable for decades.
Design for the "Circuit" flow. Position your sauna within 10 to 15 feet of your cold plunge. This proximity allows for the rapid transition required for thermal shock therapy. If you're chasing the sunset, orient the glass toward the west, but use architectural elements to shield your view from the house next door.
Austin Permitting and Code Compliance
Austin city code generally requires accessory structures to stay 5 to 10 feet away from side and rear property lines. If your unit exceeds 200 square feet or includes permanent plumbing, it's a permanent structure in the eyes of the city. Neighborhoods like Barton Creek and Circle C have strict HOA guidelines. They often require exterior finishes that match the primary residence, so plan for cedar or stone accents early in the design phase.
Privacy and Architectural Screening
Privacy is a tactical necessity for a true wellness zone. Use modern horizontal fencing to create a secluded perimeter that doesn't choke off the breeze. Pair the hardscape with native West Texas plantings like Texas Sage or Yucca. These species thrive in 100-degree heat and provide year-round visual density. Finish the space with low-voltage LED lighting for safe, high-end nighttime sessions.

The BigDecks Advantage: Integrating Wellness into a Master Backyard Plan
Dropping a pre-built cedar box in the corner of your yard doesn't create a recovery zone; it creates an obstacle. Most outdoor saunas fail to reach their potential because they lack architectural context. We treat the sauna as a core structural element rather than a disconnected add-on. When a project is integrated correctly, it stops looking like a backyard shed and starts feeling like a private resort, drawing inspiration from elite European wellness destinations like Beim Wartner that master the balance between architecture and nature.
Before we cut a single beam, we use 3D design renderings to map the entire footprint. This allows you to see how the sauna door swing affects foot traffic or how the evening sun hits the glass at 6:00 PM. We solve the logistics of electrical runs, ventilation, and drainage in virtual reality. This process eliminates expensive mid-build pivots and ensures the final structure aligns perfectly with your home's existing lines.
Our team manages the entire lifecycle of the build. We handle the site leveling, foundation piers, and structural framing required to support heavy equipment. You don't have to coordinate between a carpenter, an electrician, and a landscaper. We provide a single point of accountability from the first shovel in the ground to the final finish coat.
The circuit design: sauna, plunge, and deck
High-performance recovery relies on the transition. We design "The Circuit" to facilitate the shift from 180-degree heat to a 50-degree cold plunge. This involves strategic zoning on the deck to keep wet areas separate from dry lounge spaces. Integrating hot tubs into this layout creates a professional-grade thermal suite; to keep these units efficient and debris-free, many owners rely on Northern Hot Tub Covers for a custom fit. We prioritize textured, non-slip surfaces and thermal-treated woods to ensure the path between zones is safe and durable.
Craftsmanship and precision metalwork
Modern Austin architecture demands a specific aesthetic. We combine traditional heavy-duty carpentry with custom, powder-coated steel accents. This hybrid approach allows outdoor saunas to withstand Texas humidity while matching the clean, industrial lines of contemporary homes. Our commitment to precision engineering means your sanctuary is built to last as long as the house itself. We don't build temporary fixes; we build permanent assets that increase property value.
Building a recovery space is an investment in your daily performance. By focusing on smart design and rugged materials, we ensure your backyard serves as a functional tool for health. If you're ready to move beyond basic upgrades, let's look at how an integrated wellness plan can work for your specific property.

Frequently Asked Questions
Do I need a permit for an outdoor sauna in Austin?
Austin building code states you don't need a building permit for accessory structures under 200 square feet. You'll still need a specific electrical trade permit for the 240v line. Most high-end outdoor saunas require this dedicated circuit to hit peak temperatures quickly. Don't skip this step, or you'll risk failing a home inspection during a future sale.
How much does it cost to run an electric sauna heater in Texas?
Running a standard 8kW heater costs about $1.12 per hour based on Austin Energy’s 2024 Tier 1 rate of $0.14 per kWh. If you use your sauna for three one-hour sessions every week, your monthly cost stays under $15. It's a low-cost utility compared to the high-performance recovery benefits you get in return.
Can I put an outdoor sauna directly on my existing wood deck?
You can place a sauna on a deck if the framing supports 50 to 70 pounds per square foot. Most barrel-style outdoor saunas weigh between 800 and 1,200 pounds, which creates a concentrated load your joists must handle. We recommend adding blocking or extra posts under the footprint to prevent sagging or structural failure over time.
What is the best wood for an outdoor sauna in Austin humidity?
Thermowood is the top performer for Austin’s 65% average humidity because the thermal modification process prevents rot and warping. Western Red Cedar is a close second, using its natural tannins to fight off Texas pests and decay. Avoid budget woods like hemlock; they'll buckle and split after two seasons in the Central Texas heat.
How often do I need to maintain or re-oil my outdoor sauna?
Plan to apply a UV-inhibiting oil to the exterior every 12 months to prevent the wood from turning gray. The interior should never be stained or oiled; instead, scrub the benches with a mild soap every 10 sessions to remove body oils. This simple routine protects your investment and keeps the wood from cracking under the intense Texas sun.
Is an infrared sauna better than a traditional steam sauna for Austin?
Traditional saunas are the winner for Austin because they hit 185 degrees, providing the intense heat stress needed for athletic recovery. Infrared units max out around 140 degrees, which feels lukewarm when it's already 105 degrees outside in July. If you want a true physiological response, stick with a traditional heater and rocks for that high-performance steam experience.
Thermally Modified Wood: The Austin Homeowner’s Guide to Durable Decking
Tired of warped decks in Austin? Our guide to thermally modified wood shows how to get a durable, low-maintenance deck that survives the intense Texas heat.
Your neighbor’s cedar deck is already a warped, splintered mess, and it hasn't even seen its third Austin summer. It’s a predictable failure. Traditional lumber isn't built to survive 105 degree afternoons followed by a Central Texas humidity spike. You deserve a better ROI than a structure that looks like a roller coaster after 24 months. This is why thermally modified wood is the strategic choice for homeowners who want the soul of real timber without the maintenance nightmare of softwoods.
We know you’re tired of the plastic look of composite but hate the thought of watching real timber warp in the heat. This guide proves you can have a 25 year lifespan and the elite aesthetic of high end hardwoods without the soul crushing maintenance. You’ll see how this heat treated lumber resists rot, stays dimensionally stable during humidity swings, and remains significantly cooler underfoot than synthetic alternatives. We’re stripping away the fluff to explain the costs, the science, and why this is the smartest play for a premium Austin deck.
Key Takeaways
- Understand why Austin’s extreme UV exposure destroys standard pressure-treated pine and how to choose a material that resists rot and silvering.
- Explore the science of thermally modified wood to see how a chemical-free, high-heat process creates a molecularly stable and durable deck board.
- Compare the long-term maintenance costs and installation advantages of modified timber against traditional luxury options like Ipe and Cedar.
- Identify the best high-performance applications for your project, including sag-resistant horizontal fencing and deck surfaces that stay cool under the Texas sun.
- Learn how a design-build approach with 3D modeling ensures your material selection maximizes both architectural beauty and property ROI.
Why Austin Climate Demands Thermally Modified Wood
Austin's climate is a graveyard for standard softwoods. Pressure-treated pine and untreated cedar often fail within 7 to 10 years because they cannot survive the 40-degree temperature swings and punishing UV index. Central Texas sees an average of 25 days over 100 degrees annually; this heat literally cooks the lignin out of traditional lumber. This process leads to rapid silvering and structural breakdown that turns a premium investment into a liability. Thermally modified wood offers a "set it and forget it" stability that traditional materials simply cannot provide.
The Austin Heat Stress Factor
In 2023, Austin recorded 74 days with temperatures hitting triple digits. This intense heat bakes moisture out of standard boards, causing them to shrink rapidly and lose structural integrity. When the inevitable flash floods arrive, the wood swells just as fast. This aggressive shrink-swell cycle creates deep structural cracks and warped boards that pull away from their fasteners. Because thermally modified wood is processed at temperatures reaching 419 degrees Fahrenheit, its moisture content remains consistently low, usually between 4% and 6%. This dimensional stability ensures your high-end architectural lines stay straight through every drought cycle.
Rot and Pest Resistance in Central Texas
Standard lumber relies on toxic chemical injections to ward off termites and rot. Thermally modified wood uses a high-heat steam process to remove hemicellulose, which are the natural sugars that Austin pests crave. Without these sugars, the wood is no longer a viable food source for wood-boring insects or rot-inducing fungi. This material achieves Class 1 durability, the highest rating available in the industry. It means your deck can last 25 years or more without the rot issues common in Douglas Fir or local cedar. Consider these performance advantages:
- Class 1 Durability: Rated for a 25 plus year lifespan in outdoor conditions.
- Sugar-Free: Heat treatment removes the biological food source for termites.
- Zero Toxins: Safe for bare feet and pets without chemical leaching.
Choosing the right material is about managing the ROI of your outdoor space. While cedar might look good on day one, it requires constant staining to fight the silvering caused by Austin's UV exposure. Thermally modified options provide a consistent, dark aesthetic that ages gracefully and holds its shape. You get a deck that performs like a strategic asset rather than a maintenance project. It is the professional choice for homeowners who want to win the battle against the Texas sun.
The Science of Thermal Modification: More Than Just Baking
Thermal modification isn't a surface-level treatment or a chemical soak. It is a fundamental shift in the wood's DNA. By using only high heat and steam, we move beyond traditional lumber limits to create a product that handles the brutal Austin sun without flinching. The process requires temperatures exceeding 375°F, which effectively "cooks" the sugars and compounds out of the cells. This leaves behind a material that is hydrophobic; it practically refuses to absorb water, making it immune to the typical expansion and contraction that destroys standard decks.
The result is a board that is dark, rich, and chocolate brown all the way through to the core. You won't find any green chemical tints or superficial stains here. Because the cellular structure is permanently altered at a molecular level, the wood becomes dimensionally stable. It stays flat, straight, and resists rot because the nutrients that fungi and insects usually feed on have been carbonized. It is a clean, non-toxic solution for homeowners who want the performance of tropical hardwoods without the environmental guilt.
The Three Stages of Modification
The transition to thermally modified wood happens in three distinct, controlled phases. First, high-temperature kiln drying strips the wood of its moisture until it reaches nearly 0%. This prep work ensures the wood won't crack during the intense heat of the second stage. Next, the wood "cooks" in an oxygen-free environment to prevent combustion. This is where the chemical-free transformation occurs, altering the hemicellulose. Finally, the wood undergoes controlled cooling and reconditioning. We introduce steam to bring the moisture content back to a stable 4% to 7%, ensuring the final product is ready for the humidity swings of Central Texas.
Species Matters: Ash vs. Pine vs. Radiata
Not all species react the same way to the kiln. Selecting the right wood depends on your specific goals for durability and aesthetics. Thermally modified Ash is often called the "Ipe killer" because it offers incredible hardness and a sophisticated grain pattern that rivals expensive imports. It carries a Class 1 durability rating, meaning it's built to last 25 years or more in direct ground contact scenarios. If you are looking for a high-end finish that can take a beating, ash is the clear winner.
For those prioritizing value, modified Pine is a cost-effective entry point. It outperforms standard cedar in every metric, especially regarding rot resistance and stability. However, many Austin homeowners are moving toward Radiata Pine for its clear, knot-free appearance. It provides a sleek, modern look that fits perfectly with contemporary architectural designs. If you are still weighing these options, you can view our material comparison guide to see how these species perform in real-world builds. Each species offers a unique balance of cost and character, but all benefit from the same high-heat science that makes them Austin-ready.
Thermally Modified Wood vs. The Austin Standards
Austin deck builds usually default to three traditional materials: Cedar, Ipe, or Composite. Each choice carries a specific trade-off that often catches homeowners off guard after the first three summers. Cedar rots without constant intervention; Ipe is a logistical nightmare to install; and Composite retains enough heat to cause discomfort in July. Thermally modified wood bridges these gaps by offering the structural stability of a tropical hardwood with the thermal performance of a natural timber.
Ipe is often praised for its 50 year lifespan, but it's an environmental burden that destroys expensive carbide saw blades during construction. Thermory ash provides comparable durability without the 5,000 mile shipping route from the Amazon. It weighs roughly 35% less than Ipe. This weight reduction translates to faster installation times and lower labor costs for the homeowner. BigDecks views this material as the strategic middle ground for luxury builds because it delivers the prestige of real wood without the high-stress maintenance of softwoods.
Composite decking relies on petroleum-based resins that act as heat sinks. On a 105 degree Austin afternoon, composite surface temperatures can peak at 160 degrees, making it impossible to walk on barefoot. Natural wood remains significantly cooler. Because the modification process removes the sugars that absorb moisture, the boards don't warp or cup like standard lumber. You get the organic feel of a high-end outdoor living space without the plastic aesthetic or the scorching surface temperatures.
The cost-benefit analysis for homeowners
A Cedar deck might save you $6,000 on the initial quote, but that "saving" disappears by the seventh year. Professional staining and sealing in Central Texas costs approximately $3.50 per square foot every two years. Over a 15 year period, the cumulative maintenance spend on Cedar often exceeds the total price of a premium thermally modified wood installation. Homeowners can choose to re-oil the wood to keep its deep chocolate hue or let it weather to a sophisticated silver-gray. Either way, the structural integrity remains intact without the constant need for chemical sealants.
Sustainability and the eco-conscious build
Most exotic hardwoods are harvested from sensitive ecosystems where tracking legal sourcing is difficult. In contrast, modified woods utilize domestic, sustainably managed forests. The modification process uses only high heat and steam, meaning zero toxic chemicals are injected into the lumber. This makes the boards 100% biodegradable at the end of their life cycle. It also ensures that no harmful runoff enters Austin's local groundwater or the Edwards Aquifer during heavy rain cycles. It's a clean, high-performance solution that respects the local environment.
Best Applications for Your Austin Backyard Project
Austin's climate eats standard building materials for breakfast. You need a material that handles 105-degree August afternoons and sudden flash floods without flinching. Thermally modified wood provides the structural stability required for high-performance applications, moving beyond simple flooring to become a versatile tool for total outdoor transformations.
Designing the Modern Horizontal Fence
Horizontal fences are the gold standard for modern Austin curb appeal, but they often suffer from a fatal flaw: sagging. Standard cedar or pressure-treated boards eventually bow under their own weight, which ruins the clean lines of a contemporary design. Thermally modified wood is the secret weapon for these projects because the heat-treatment process removes the moisture and sugars that cause timber to warp or twist.
We recommend pairing these ultra-straight boards with custom black powder-coated steel posts for a high-contrast, industrial look. This combination ensures your privacy screen stays perfectly aligned for decades. If you are planning a perimeter upgrade, explore our guide on horizontal fences to see how these materials create a true privacy fortress. It is about building a structure that looks as sharp in year ten as it does on day one.
Poolside Decks and Water Features
Concrete and limestone pool surrounds are notorious heat magnets that scorch bare feet by noon. Thermory decking remains significantly cooler than stone or composite alternatives, often staying 20 to 30 degrees lower in surface temperature during peak sun exposure. Its hydrophobic nature means it does not soak up pool chemicals or water, which prevents the rot and cupping common in traditional wood decks.
Many Austin homeowners are now integrating outdoor saunas and cold plunges into their backyard layouts. This timber thrives in these high-moisture environments. You get a splinter-free surface that resists mold growth, even when it is constantly exposed to splashes and steam. It creates a cohesive design play that connects your pool, deck, and wellness features into one high-end narrative.
Architectural Cladding and Accents
The utility of this material extends to the walls of your home. Using thermally modified wood for architectural cladding provides a modern facelift that rivals the look of expensive tropical hardwoods like Ipe. It functions as a durable rainscreen, protecting your home’s exterior while adding organic warmth to cold materials like glass and steel. It is a strategic move for homeowners looking to increase property value through high-end, low-maintenance aesthetics.

Frequently Asked Questions
Does thermally modified wood require any maintenance in the Texas sun?
Thermally modified wood needs a UV-inhibiting oil application every 12 to 18 months if you want to retain its original dark brown color. The Austin sun delivers high UV loads that bleach natural timber quickly. If you don't apply a finish like Cutek Extreme, the boards will transition to a silver patina, though the wood remains structurally sound and resistant to rot.
Is thermally modified wood as strong as Ipe or other hardwoods?
Ipe is denser with a Janka hardness rating over 3,500 lbf, but thermally modified wood wins on dimensional stability. Thermory Ash typically tests around 1,300 lbf, which is plenty of strength for high-traffic residential decks. It doesn't have the internal tension found in tropical hardwoods, meaning your boards won't cup, twist, or warp when the Texas humidity spikes to 90%.
Can I leave thermally modified wood to turn gray naturally?
You can leave the wood to weather naturally without voiding the 30-year warranty or risking structural failure. This silvering process usually takes 6 to 12 months depending on how much direct sunlight your deck receives. Many homeowners in Central Texas choose this route because it eliminates the need for biennial staining while providing a clean, modern aesthetic that fits the local landscape.
Is thermally modified wood more expensive than cedar in Austin?
Expect to pay about 60% to 80% more for thermally modified wood than you would for premium Western Red Cedar. While cedar might cost $5 per linear foot, Thermory Ash often sits between $9 and $12 per linear foot in the Austin market. The higher upfront cost is a strategic play for longevity, as this material is rated to last 30 years compared to the 15-year average lifespan of cedar.
How long does a thermally modified wood deck last?
A thermally modified wood deck is engineered to last 25 to 30 years even in harsh climates. The modification process uses heat over 400 degrees Fahrenheit to remove the sugars and moisture that lead to decay. This results in a Class 1 durability rating, which is the highest possible standard for timber longevity and performance in outdoor environments.
Is thermally modified wood resistant to termites in Central Texas?
Termites and other wood-boring insects generally avoid this material because the thermal process destroys the nutrients they need to survive. By cooking out the hemicellulose and natural starches, the wood becomes an invisible food source for pests. You get the benefit of a 100% natural product that doesn't require the toxic chemical injections found in standard pressure-treated lumber.
