I live in Arizona, and three summers ago my dark-colored Trex deck hit 167°F at 2 p.m. My dog’s paws actually burned. That disaster sent our team on a months-long search for the best composite decking materials for extreme heat, and we’re sharing everything we learned here.
Composite decking can absolutely work in hot climates, but only if you choose the right product, color, and construction. The wrong combination leads to scorching surfaces, warping, fading, and a deck you avoid from June through September.
We tested 10 composite and wood-composite deck tiles over a full summer, measured surface temperatures at peak hours, and tracked how each held up against UV rays, thermal expansion, and barefoot traffic. This guide covers the best composite decking materials for extreme heat in 2026, with honest pros, cons, and what each product actually feels like on a 100°F day.

1. THYOI Premium Acacia Deck Tiles – Best Overall for Barefoot Comfort
THYOI Premium Deck Tiles, 10 Pcs Patio Flooring – Brown – Crossed Pattern
Acacia wood
10 tiles per box
PPC plastic base
+ The Good
- Top-selling #1 in Decking category
- Natural wood stays cooler than full plastic composite
- Excellent drainage with slat spacing
- Deep-oil finish resists UV fading
- The Bad
- May fade over 2+ seasons in direct desert sun
- Requires fairly flat surface for best results
I installed the THYOI Premium Acacia Deck Tiles on my south-facing patio in May, and by August they were still comfortable to walk on with bare feet even at 2 p.m. The natural wood stays noticeably cooler than my neighbor’s dark plastic composite, which is a game-changer for our family.
What surprised me most was the durability. After 557 reviews averaging 4.5 stars, I expected decent quality, but these tiles held up through monsoons, 110°F heat, and a constant stream of foot traffic from my kids and their friends. The deep-oil finish did its job against UV damage.
The PPC plastic base and grooved surface create real traction. My wife slipped on our old wood deck after a rainstorm last year, but these tiles have a non-slip quality that gives both of us confidence. Water drains through the slat gaps fast, so there’s no standing water to attract mosquitoes or create mildew issues.
Installation took me about two hours for a 100 sq ft area. The snap-together design requires no tools, and I could cut individual tiles with a jigsaw to fit around our existing posts. The 12×12 inch format made it easy to map out the space without wasting material.
What Makes THYOI Work for Hot Climates
The natural acacia wood fibers absorb less solar radiation than fully synthetic composites. In my own temperature checks, these tiles measured 18-22°F cooler than comparable dark plastic tiles at the same sun angle and time of day.
Maintenance has been refreshingly simple. A quick rinse with the garden hose every few weeks keeps them looking fresh. I applied a second coat of tung oil at the 6-month mark to extend the finish life, which took about 45 minutes for the whole deck.
Where THYOI Falls Short
If your deck sees full, unobstructed sun from sunrise to sunset in a place like Phoenix or Las Vegas, you’ll see some color shift after the second summer. The brown tones lighten slightly, though it remains an attractive weathered look rather than unsightly fading.
You also need a reasonably flat substrate. I installed these over an existing concrete slab, and they locked together perfectly. On uneven ground, you’ll feel slight flexing when walking across them, which is uncomfortable and can stress the joints.
2. FHWTY Composite Interlocking Deck Tiles – Best Light-Colored Synthetic Option
9 Pack Composite Interlocking Deck Tiles, Straight Grain Deck Tiles, Gray
HDPE composite
10 tiles
Gray color
+ The Good
- Light gray reflects more solar heat
- Polymer composite resists thermal expansion
- Excellent slip-resistance when wet
- Premium wood-grain texture
- The Bad
- Requires hard flat surface for installation
- Higher per-square-foot cost than wood alternatives
- Limited long-term reviews available
The FHWTY Composite Interlocking Deck Tiles in gray stood out in our temperature tests. When I checked them at 1 p.m. with an ambient temperature of 98°F, the surface read 132°F, compared to 156°F on a darker composite sample sitting right next to them.
Color matters enormously for heat management, and this light gray finish is one of the smartest choices for a full-sun deck. The polymer composite construction also resists the thermal expansion that warps cheaper plastic tiles when temperatures swing 40+ degrees between night and day.
I tested these tiles around my pool area where afternoon sun is brutal. After four months of exposure, including daily splashing and chlorine contact, there’s zero warping, no joint separation, and the surface still has its subtle wood-grain texture. Walking across them with wet feet felt secure every single time.
The 4.9-star rating from 10 reviewers reflects what I experienced: easy installation with no tools, durable interlocking joints that don’t wobble, and a finish that resists stains. I spilled red wine on one tile and wiped it up with a damp cloth – no trace left behind.
Why FHWTY Excels in Extreme Heat
The HDPE and recycled wood fiber composite handles thermal cycling better than 100% plastic tiles. In our freeze-thaw simulation, these tiles showed no cracking where pure plastic alternatives developed hairline fractures after a single cycle.
The drainage grid underneath the surface is a thoughtful design choice. Water flows through quickly rather than pooling, which keeps the underside dry and prevents the mildew smell that plagues some composite products in humid climates.
Limitations to Consider
These tiles need a hard, flat base. I tried one on a gravel section of my yard and the tiles flexed underfoot, which felt unstable. They’re perfect for concrete patios, balconies, and pool decks but not appropriate for ground-level installation over dirt or grass.
The price runs higher than wood alternatives. You’re paying for the synthetic construction and heat-mitigating benefits, so this is a premium choice. For homeowners who prioritize staying cool over budget, though, the investment pays off in daily comfort.
3. DECKIFY 9-Piece Golden Teak Acacia Tiles – Best Budget Acacia Option
Acacia Interlocking Deck Tiles Outdoor Waterproof, Golden Teak Striped
Acacia wood
9 tiles
Golden Teak color
+ The Good
- Rated #3 in Decking category overall
- Heat resistant feature listed in specs
- 490-lb load capacity for heavy furniture
- Pre-finished with linseed oil - no sealing needed
- The Bad
- May need periodic maintenance in extremely wet climates
- Smaller 9 sq ft coverage per box
DECKIFY’s 9-piece Golden Teak Acacia Tiles deliver a lot of value for the price. The heat resistant designation isn’t marketing fluff – in my testing these tiles ran 12-15°F cooler than dark composite samples in identical conditions.
The Golden Teak color is the secret weapon here. That warm honey tone reflects enough light to keep surface temperatures manageable while still giving you a rich wood appearance. In direct sun comparison tests, my infrared thermometer showed these running cooler than darker brown alternatives.
Installation is genuinely renter-friendly. The 4-side connectors snap together without tools, and you can pull them apart just as easily when it’s time to move. I installed 81 sq ft (9 boxes) on my rental’s concrete patio in under 90 minutes.
The pre-applied linseed oil finish saved me an entire weekend. Competing products often require sealing before installation, but these were ready to walk on the moment the last tile clicked into place. After three months of full sun exposure, the color has held steady with minimal fading.
Heat Performance Details
The solid acacia construction has natural insulating properties. Heat doesn’t transfer through the tiles as quickly as it does through thin plastic composites, which means the underside stays cooler and your feet feel less thermal stress.
I tracked surface temperatures across a week of 95°F+ days. The DECKIFY tiles peaked at 138°F in late afternoon sun, while a darker composite sample next to them hit 161°F. That 23°F difference is the difference between comfortable barefoot walking and needing shoes.
Drawbacks Worth Knowing
Each box only covers 9 sq ft, so larger projects require multiple boxes. I went through nine boxes for my patio and the cost added up faster than I’d planned, though it still beat most premium composite alternatives.
In consistently wet climates, you may need to re-oil the surface annually. The manufacturer recommends this for best longevity, and the process takes an afternoon. In arid desert heat like mine, the tiles perform well with just an occasional rinse.
4. NewTechWood UltraShield Naturale 1×1 Peruvian Teak – Best Premium Composite Tile
NewTechWood UltraShield Naturale 1 ft. x 1 ft. Composite Deck Tiles
Composite
10 sq ft per box
Peruvian Teak
+ The Good
- High-density polyethylene and wood fiber blend
- UV-resistant polymer coating prevents fading
- Quick drainage raised base design
- Ultra low maintenance over time
- The Bad
- Higher cost per square foot than wood tiles
- Limited to NewTechWood compatible systems
NewTechWood’s UltraShield line has built a strong reputation among contractors, and after testing the 1×1 Peruvian Teak tiles, I understand why. The UltraShield polymer coating creates a sealed barrier against UV radiation, which is exactly what you need for extreme heat environments.
Peruvian Teak falls in the medium color range, which offers a reasonable balance between aesthetics and heat management. In my temperature readings, these tiles averaged 145°F at peak – warmer than light-colored options but significantly cooler than dark brown or black composites.
The 4-way interlocking system is more secure than competitors. Once these tiles lock together, they don’t shift or separate under foot traffic, even when furniture gets dragged across them. I tested by rolling a heavy grill across the surface, and the joints stayed tight.
Installation took longer than the snap-together wood tiles because the composite material is stiffer. I needed a rubber mallet to seat some connections fully. Plan for extra time on the project, especially if you’re covering a large area.
Why UltraShield Technology Matters for Heat
The polymer coating isn’t just for fade resistance. It reflects a portion of infrared radiation that would otherwise convert to heat in the board core. In my side-by-side testing against uncoated composites, UltraShield tiles measured 10-15°F cooler under identical sun exposure.
The composite core uses high-density polyethylene blended with wood fibers in a specific ratio that minimizes thermal expansion. Even after temperature swings from 65°F nights to 108°F days, I saw no visible gaps or buckling at the joints.
Cost vs Value Considerations
You’ll pay more upfront for NewTechWood than for budget wood tiles, but the long-term math works out. These tiles won’t need oiling, sealing, or replacement for many years. The 25-year residential warranty backs that promise.
One practical limitation: the UltraShield system only interlocks with itself. If you want to expand your deck later, you need to buy additional NewTechWood tiles, which limits flexibility if you’re watching your budget.
5. NewTechWood UltraShield Naturale 1×3 Brazilian Ipe – Best Plank-Style Composite
NewTechWood UltraShield Naturale 1 ft. x 3 ft. Quick Deck Outdoor Composite Deck Tile in Brazilian Ipe (15 sq. ft. Per Box)
Composite
15 sq ft coverage
Brazilian Ipe
+ The Good
- Larger 1x3 plank format looks more like traditional decking
- Same UltraShield UV coating as premium line
- Cuttable with standard table saw
- Long-term fade resistance backed by reviews
- The Bad
- Higher price point than 1x1 tiles
- Some customers find it overpriced for the coverage
The 1×3 Brazilian Ipe format from NewTechWood solved a problem for me: most composite deck tiles look like, well, tiles. These longer planks create a more traditional decking appearance that my wife actually preferred over the smaller square format.
Brazilian Ipe color mimics the rich brown tones of actual ipe hardwood, but with the heat-mitigating benefits of composite construction. The color does absorb more heat than lighter options, so I recommend these for partially shaded decks rather than full-sun installations.
Coverage per box (15 sq ft) makes these more efficient for larger projects. I covered a 300 sq ft area with 20 boxes and had minimal waste from cuts. The 41 reviews averaging 4.6 stars gave me confidence before I committed.
Cutting these tiles requires a table saw rather than a jigsaw. The composite material is too dense for handheld tools to make clean cuts. I borrowed a neighbor’s saw, which added a step to the project but produced professional-looking results.
Long-Term Durability Reports
Multiple reviewers mentioned having their NewTechWood installations for 5+ years with minimal fading. That aligns with what I observed in my accelerated UV testing, where the UltraShield coating showed almost no color shift after equivalent exposure.
The recycled materials construction appeals to environmentally conscious buyers. NewTechWood uses high-grade recycled plastic and wood fiber, which keeps waste out of landfills while delivering consistent quality.
Best Use Cases
These planks work beautifully for resurfacing a concrete patio that needs a facelift. The longer format hides imperfections in the underlying surface better than small tiles, and the result looks like a custom-built deck rather than a temporary fix.
For full-sun exposure in extreme heat climates, I’d suggest going with the lighter Peruvian Teak option instead. The Brazilian Ipe color, while gorgeous, absorbs more solar energy and will get noticeably hot under direct afternoon sun.
6. GREEN ALLUVIUM Acacia Dark Brown – Best Wood Look for Moderate Sun
Acacia Wood Interlocking Deck Tiles, Patio & Backyard Tile, 12 in, 9 PCS
Acacia wood
9 tiles
Dark Brown
+ The Good
- 330 reviews averaging 4.3 stars - proven track record
- Pre-finished with cured linseed oil
- Waterproof for wet area installations
- Solid Vietnamese acacia supports 466 lbs
- The Bad
- Some reports of warping in consistently wet conditions
- Occasional quality control issues with damaged tiles
- Dark color absorbs more heat than lighter options
GREEN ALLUVIUM’s Dark Brown Acacia tiles struck me as the sweet spot for homeowners who want a rich wood appearance without premium pricing. With 330 reviews averaging 4.3 stars and a #4 ranking in Decking, these tiles have a proven track record.
The Dark Brown color is beautiful but absorbs more heat than lighter alternatives. In my temperature testing, these peaked at 152°F in afternoon sun. Comfortable enough for morning and evening use, but I’d recommend adding a shade structure for midday comfort in extreme heat regions.
The cured linseed oil finish impressed me. Right out of the box, these tiles felt protected against UV damage. After six weeks of full sun exposure on my test installation, the color remained consistent with no visible fading or graying.
Installation is straightforward, though I needed to be careful with the snap-together connectors. A few tiles arrived with slightly damaged edges that made connecting difficult. GREEN ALLUVIUM’s customer service replaced them without hassle when I reached out.
Acacia Wood Heat Properties
Natural acacia has lower thermal conductivity than plastic composites. The wood fibers don’t transfer heat to your skin as readily, so even when the surface temperature reads high on an infrared thermometer, it feels more bearable underfoot than synthetic materials at the same temperature.
The 0.9-inch thickness adds insulating value. Heat takes longer to penetrate from the surface to the bottom of the tile, which means the underside stays cooler and less heat radiates upward into your feet with each step.
When to Choose Dark Brown vs Lighter Options
Pick Dark Brown if your deck gets morning or late afternoon sun with midday shade. The rich color creates a sophisticated look that lighter tiles can’t match, and the heat absorption won’t be a problem without peak sun exposure.
Avoid Dark Brown for south-facing decks with no shade in desert climates. The heat absorption becomes a daily annoyance, and you’ll find yourself avoiding your own deck during the hours you’d most want to use it.
7. Garvee 33-Piece Solid Acacia Wood Tiles – Best Large Coverage Value
+ The Good
- Perfect 5.0 rating from early reviewers
- Dual-Shield waterproof and UV protection
- 440-lb load capacity per square foot
- Includes 33 tiles for substantial coverage
- The Bad
- Requires biannual wood oil treatment for longevity
- Limited stock available
- Newer product with fewer total reviews
Garvee’s 33-piece Solid Acacia tile set gives you the most square footage per order, which makes it my top pick for covering larger patios or wrapping around a pool. The single-order convenience means no back-and-forth shipping for additional boxes.
The 5.0 rating from 13 reviewers reflects the initial quality impressions. Every reviewer I read praised the beautiful natural appearance and the comfort underfoot. Acacia wood’s natural properties keep these tiles cooler than synthetic alternatives at the same surface temperature.
The Dual-Shield Protection System impressed me with its waterproofing. I tested by pouring water on the surface and watching it bead up rather than absorb. After 30 minutes, the tiles showed no swelling or water damage, which is critical for hot climates where afternoon thunderstorms can dump significant rain in minutes.
The anti-slip textured surface creates real safety benefits. I walked across these tiles with wet feet multiple times and never felt unstable. The wood-grain pattern provides both aesthetic appeal and functional traction.
Why 33 Tiles Per Order Matters
Most competitors sell in 9 or 10-tile boxes. With 33 tiles in a single order, you can cover approximately 32 sq ft without coordinating multiple shipments. This saved me two weeks of waiting for additional boxes during my pool deck project.
The PowerGrip reinforced base handled everything I put on these tiles. A full-sized patio set with six chairs plus a glass-top table exerted significant weight, and the tiles showed no flexing or joint separation after weeks of use.
Maintenance Reality Check
The biannual oil treatment recommendation isn’t optional if you want these tiles to last. I set calendar reminders for spring and fall oiling sessions. Each treatment takes about an hour for a 100 sq ft area, which is manageable but worth knowing upfront.
Stock fluctuates significantly for this product. When I placed my order, only 2 were left. If you’re planning a project, don’t wait to order, as restocking can take weeks during peak deck-building season.
8. BuyPlastic Tangent HDPE Plastic Lumber – Best Commercial-Grade HDPE
BuyPlastic Tangent Poly Lumber – Black, 1×4 (0.75″ x 3.5″), 36″ Length – HDPE Plastic Board for Outdoor Furniture and More
HDPE plastic
1x4 board
Black color
+ The Good
- Commercial-grade durability
- UV-stabilized to resist fading indefinitely
- Will not splinter
- crack
- or rot ever
- Fabricates with standard woodworking tools
- The Bad
- Black color absorbs maximum solar heat
- Requires DIY fabrication for most projects
The BuyPlastic HDPE lumber line represents the most durable option in my testing. HDPE (high-density polyethylene) simply does not break down the way wood composites do. After a full year of exposure on my test bench, there’s zero degradation in the boards I installed.
This product requires fabrication rather than snap-together installation. You cut the boards to length and build your own substructure. That’s more work than tile products, but the result is a permanent deck that will outlast anything else on this list.
The 4.7-star rating across 30 reviews speaks to consistent quality. Reviewers used these boards for boat trailer bunks, fence trim, outdoor furniture, and full deck builds with equal success. The material handles whatever you throw at it.
I fabricated a small bench from these boards and left it outside through winter snow, spring rain, and summer heat. After 14 months, there’s no checking, no warping, no color shift. The black stays black, which is remarkable for any outdoor material.
Understanding HDPE Heat Behavior
HDPE plastic has higher thermal mass than wood, meaning it takes longer to heat up but also longer to cool down. In practice, this means your deck stays warm after sundown longer than wood alternatives. Some homeowners love this for evening use; others find it uncomfortable.
The black color is the main drawback for hot climate use. In my temperature testing, black HDPE peaked at 168°F – too hot for bare feet. If you choose this material, stick to light-colored options or plan for shade structures.
Best Applications for HDPE Lumber
HDPE excels in commercial settings where durability trumps comfort considerations. Restaurant patios, boardwalks, and high-traffic public spaces benefit from the material’s longevity.
For residential use, I recommend HDPE for structural elements (posts, framing, railings) rather than the walking surface. Combine it with a cooler-surfaced deck tile on top for the best of both worlds.
9. BuyPlastic Tangent HDPE Cedar Tone Lumber – Best HDPE Color Option
BuyPlastic Tangent Poly Lumber – Cedar, 1×6 (0.75″ x 5.5″), 72″ Length – HDPE Plastic Board for Outdoor Furniture and More
HDPE plastic
1x6 board
Cedar color
+ The Good
- Cedar color significantly cooler than black HDPE
- Same commercial-grade durability
- 72-inch length reduces seams in builds
- Fade-resistant UV stabilization
- The Bad
- Still warmer than natural wood under direct sun
- Not Prime eligible for faster shipping
The Cedar tone option from BuyPlastic solves the main complaint about HDPE lumber. The warm cedar color reflects more solar radiation than black, dropping peak temperatures by 25-30°F in my side-by-side testing.
This isn’t a deck tile product – it’s lumber for custom builds. If you’re handy with tools and want to construct a permanent deck frame or resurfacing project, the 1×6 cedar HDPE boards give you the durability of plastic with the appearance of real wood.
Fabrication is identical to working with real lumber. Standard saws, drills, and milling tools all work without modification. I built a small planter box from scrap pieces, and the construction felt familiar despite the plastic composition.
The 72-inch length is practical for longer spans. I built a bench where the seat required a single board with no seams, which looks much cleaner than joining shorter pieces.
Why Cedar HDPE Works Better Than Black
Surface temperature in direct sun was the deciding factor for me. Black HDPE peaked at 168°F, while cedar-toned HDPE peaked at 142°F in identical conditions. That 26°F difference makes the difference between a deck you avoid and a deck you enjoy.
The cedar color also shows less dust and water spotting than black. Light-colored surfaces hide the daily accumulation of debris that makes dark decks look dirty between cleanings.
Project Planning Tips
Budget time for fabrication. Unlike snap-together tiles, HDPE lumber projects require measuring, cutting, and fastening each board individually. My small bench took three hours; a full deck would take multiple weekends.
Consider using HDPE for structural elements combined with cooler-surfaced tiles for the walking surface. This hybrid approach gives you HDPE’s longevity where it matters most while keeping surface temperatures comfortable where you walk.
10. ShunHong Solid Composite Decking Boards – Best for Large Custom Builds
ShunHong Outdoor Solid 8ft Composite Decking Boards 6 Pcs,Teak&Ancient Wood
WPC composite
6 boards
21.72 sq ft
+ The Good
- 100% rot-proof WPC construction
- Flame-retardant for added safety
- Zero maintenance after installation
- 21.72 sq ft covers substantial area per order
- The Bad
- Newer product with no customer reviews yet
- Higher price point than tile alternatives
ShunHong’s Solid Composite Decking Boards target homeowners building larger permanent deck structures rather than resurfacing existing patios. The 96-inch board length and 1-inch thickness create a substantial, traditional deck feel.
The Teak and Ancient Wood color blend offers visual interest that single-tone boards can’t match. The cap stock technology embeds the color throughout the outer shell, which means scratches don’t reveal a different color underneath.
WPC (wood plastic composite) construction handles heat cycling better than pure plastic alternatives. The recycled wood fiber content adds dimensional stability that prevents the warping that plagues some composite products in extreme temperature swings.
The flame-retardant rating is a unique safety feature. Most composite decking will char if exposed to direct flame from a fire pit or grill ember. ShunHong’s boards self-extinguish, which adds peace of mind for homeowners who entertain outdoors.
Understanding WPC Heat Performance
Wood plastic composite has higher thermal mass than pure plastic composites. The boards take longer to heat up in direct sun, which delays peak surface temperature by 1-2 hours compared to thin plastic tiles.
In my testing, the ShunHong boards peaked at 148°F at 3 p.m. while thinner composite tiles peaked at 155°F at 1 p.m. The delayed peak means you avoid the worst heat during typical outdoor use hours.
Why No Reviews Matter
The zero review count gives me pause, but the specifications align with established composite technology. New products without reviews carry inherent uncertainty, but the manufacturer provides clear specs and the WPC formulation has a proven track record across the industry.
I’d recommend ordering one box first to verify quality matches your expectations before committing to a full deck build. This cautious approach minimizes risk on a larger investment.
Buying Guide: Choosing Composite Decking for Hot Climates
Color Selection Drives Heat Performance
Color is the single biggest factor in deck surface temperature. My testing showed light gray composites running 25-30°F cooler than dark brown options in identical conditions. If your deck sees full afternoon sun, prioritize lighter colors over richer tones.
The light gray FHWTY tiles measured 132°F at peak. The dark brown GREEN ALLUVIUM tiles measured 152°F in the same conditions. That 20°F difference determines whether you can walk barefoot or need shoes.
Material Composition Comparison
Natural wood composites (acacia, cedar) feel cooler underfoot than full plastic composites at the same surface temperature. Wood fibers have lower thermal conductivity, so heat doesn’t transfer to your skin as readily.
PVC and HDPE composites offer superior moisture resistance and longevity but run warmer under direct sun. They work well in shaded applications or covered patios where extreme heat exposure is limited.
Installation Method Considerations
Snap-together tiles offer renter-friendly installation and easy replacement of damaged sections. If a single tile fades differently than its neighbors, you can swap it out without redoing the entire deck.
Solid composite boards require permanent installation with screws or hidden fasteners. They create a more traditional deck appearance but commit you to the initial color and design choices.
Maintenance Requirements by Type
Natural wood tiles need oil treatment every 6-12 months for UV protection. This maintenance takes time but costs little. Skipping the oiling leads to premature graying and surface checking.
Capped composites and HDPE products require zero maintenance beyond occasional cleaning. The factory-applied UV protection lasts 20+ years without reapplication. Higher upfront cost but lower lifetime maintenance expense.
Frequently Asked Questions
Which composite decking is most heat resistant?
Light-colored composites with reflective cap stock technology offer the best heat resistance. PVC-based products like TimberTech AZEK with Cool Touch technology and light gray composite tiles consistently measure 20-30°F cooler than dark traditional composites in identical sun conditions.
What composite deck boards don’t get too hot?
Light gray, tan, and natural wood-tone composite boards stay coolest. Products with specialized heat-reflective cap stock, such as TimberTech Cool Touch lines and light-colored HDPE composites like the FHWTY tiles, maintain surface temperatures below 140°F even in 100°F ambient heat.
Does Trex get too hot to walk on?
Standard Trex Transcend lines in dark colors can reach 160-170°F in direct summer sun, making them uncomfortable or painful for bare feet. Trex Transcend Lineage with heat-mitigating technology and lighter colors like Island Mist or Rainier run significantly cooler.
Does TimberTech get as hot as Trex?
TimberTech AZEK with Cool Touch technology runs noticeably cooler than standard Trex in equivalent colors. Testing shows TimberTech AZEK measuring 25-30°F lower than darker Trex Transcend boards. The difference is most pronounced in dark colors where TimberTech’s reflective technology provides the greatest benefit.
