Does composite decking get hot in direct sunlight?
Yes. Like most outdoor flooring materials, WPC composite decking can become warm or hot when exposed to strong sunlight.
However, there is no single temperature that applies to every composite deck.
A light grey WPC board installed on a ventilated balcony in a mild climate may feel very different from a charcoal board installed beside a pool in a hot, sunny region.
Surface temperature depends on several factors, including:
- Decking color
- Solar exposure
- Ambient temperature
- Climate
- Surface texture
- Airflow
- Deck orientation
- Nearby buildings
- Shade
- Board structure
For residential projects, this affects barefoot comfort.
For hotels, resorts, poolside areas and commercial projects, surface heat can also influence product selection, color planning and customer satisfaction.
Therefore, buyers should not simply ask whether composite decking becomes hot.
A better question is:
How hot is the specific decking likely to feel under the actual project conditions, and what can be done to reduce heat buildup?
This guide explains what affects WPC decking temperature, how light and dark colors differ, how climate and ventilation matter and what B2B buyers should evaluate before placing a bulk order.
Why Does Composite Decking Get Hot?
Any outdoor surface exposed to sunlight absorbs part of the sun’s energy.
That energy raises the surface temperature.
Composite decking is no exception.
WPC contains wood-based material, thermoplastic polymer, pigments and additives. These materials absorb and reflect solar energy differently depending on their formulation and color.
Therefore, WPC decking temperature is influenced by both the product and the environment.
Sunlight Is the Main Heat Source
Direct sunlight is usually the biggest factor.
A board exposed to full midday sun can become significantly warmer than the same board under:
- A pergola
- A tree
- A roof
- An umbrella
- A shaded balcony
This means the same decking product may feel comfortable in one section of a project and noticeably warmer in another.
Ambient Temperature Also Matters
The hotter the surrounding air, the more difficult it is for the decking surface to release heat.
Therefore, a deck in a 35°C summer environment will generally feel hotter than the same deck under mild spring conditions.
Ambient temperature and solar radiation work together.
Color Changes Heat Absorption
Dark surfaces generally absorb more solar energy than lighter surfaces.
As a result, dark composite decking often becomes warmer in direct sunlight.
This is why color selection is particularly important for:
- Poolside projects
- Rooftop terraces
- Tropical markets
- Desert climates
- Barefoot areas
- South-facing outdoor spaces
Does Dark Composite Decking Get Hotter?
In general, darker composite decking tends to absorb more heat under direct sunlight than lighter decking.
Common dark shades include:
- Charcoal
- Dark brown
- Deep coffee
- Black-grey
- Dark mixed wood tones
These colors can create a premium and modern appearance, but they may also become warmer under strong sun.
Therefore, design and thermal comfort need to be considered together.
Why Dark Colors Absorb More Heat
Dark surfaces reflect less visible solar energy and absorb more of it.
The absorbed energy is converted into heat.
As a result, darker boards may reach a higher surface temperature than lighter boards under similar conditions.
However, color is not the only variable.
Two dark WPC products may still perform differently because of:
- Surface formulation
- Texture
- Pigments
- Cap technology
- Board structure
- Installation
- Airflow
Therefore, buyers should not compare products by color alone.
Do Light Composite Decking Colors Stay Cooler?
Light colors generally absorb less solar heat than very dark colors.
Suitable lighter or medium shades may include:
- Light grey
- Silver grey
- Teak
- Light brown
- Sand tones
- Medium wood colors
For hot climates and barefoot applications, these colors can be more practical.
However, lighter does not mean the surface will remain cool.
Under intense sunlight, even light-colored composite decking can become warm.
The advantage is relative rather than absolute.
Medium Colors Can Be a Practical Compromise
For many projects, a medium shade provides a good balance between:
- Appearance
- Heat absorption
- Dirt visibility
- Maintenance
- Market preference
Examples include:
- Teak
- Medium brown
- Grey-brown
- Silver grey
For distributors serving different applications, medium tones can be easier to recommend than extremely dark colors.
Does Composite Decking Get Hotter Than Wood?
There is no universal answer because both composite decking and natural wood vary significantly.
Natural timber differs by:
- Species
- Density
- Color
- Finish
- Moisture level
Composite decking differs by:
- Polymer type
- Wood content
- Color
- Surface technology
- Profile
- Pigment system
Therefore, saying “all composite decking is hotter than wood” would be too broad.
In practice, dark composite surfaces can become noticeably warm in direct sunlight, while some lighter composite products may provide a more comfortable surface.
The most useful comparison should involve the actual materials, colors and project conditions.
Does Capped Composite Decking Get Hot?
Yes.
Capped or co-extruded composite decking can still become hot in direct sunlight.
The protective cap improves characteristics such as:
- Surface protection
- Stain resistance
- Moisture resistance
- Color stability
However, a cap does not prevent solar heat absorption.
Surface temperature still depends heavily on:
- Color
- Sun intensity
- Air temperature
- Surface formulation
- Exposure time
Therefore, capped decking should not automatically be marketed as “cool decking.”
Does Uncapped WPC Get Hot?
Traditional uncapped WPC can also become warm under sunlight.
Its exposed composite surface absorbs solar energy depending on the product’s color and formulation.
Therefore, both capped and uncapped products need to be evaluated for hot-climate applications.
The surface technology is only one part of the thermal performance.
Does Hollow Composite Decking Stay Cooler Than Solid Decking?
Hollow and solid profiles have different internal structures.
A hollow board contains internal chambers, while a solid board contains more material.
This can affect:
- Weight
- Heat storage
- Cooling behavior
- Structural feel
However, it is too simplistic to say that hollow decking is always cooler than solid decking.
Surface temperature is primarily influenced by direct solar exposure and the visible surface.
Board structure may affect how heat moves through the product, but buyers should not use hollow vs solid as the only criterion for selecting decking for a hot environment.
Why Surface Temperature and Core Temperature Are Different
The top surface receives direct sunlight.
Therefore, it can heat much faster than the inside of the board.
A hollow profile may contain less material, but the visible top surface can still become warm.
For barefoot comfort, the surface temperature matters more than the internal profile temperature.
Does Surface Texture Affect Heat?
Surface texture can affect how the deck feels and how sunlight interacts with the board.
Common WPC surfaces include:
- Straight grain
- Brushed surface
- Grooved surface
- 3D embossed wood grain
- Co-extruded wood grain
However, texture usually has less influence on heat than color and direct sunlight.
Deep Embossing and Touch Comfort
Deep embossed surfaces create peaks and valleys.
When walking barefoot, the foot may not contact every part of the surface equally.
This can change the way heat is perceived.
However, deep grain should not be considered a substitute for appropriate color selection in hot climates.
Smooth vs Textured Surfaces
A smoother surface may create more continuous contact with the foot.
A textured surface can slightly change contact sensation.
However, both can still become hot under strong sun.
Therefore, buyers should focus first on:
- Color
- Sun exposure
- Climate
- Shade
- Airflow
before using texture as the main thermal-selection factor.
How Climate Affects Composite Decking Temperature
Climate has a major influence on how hot composite decking feels.
The same product may perform very differently in different markets.
Composite Decking in Tropical Climates
Tropical regions often experience:
- Strong sunlight
- High temperatures
- High humidity
- Frequent rainfall
For tropical projects, buyers should consider lighter or medium decking colors, especially in highly exposed locations.
Other useful design factors include:
- Good airflow
- Shade structures
- Proper drainage
- Suitable expansion gaps
Poolside resorts and hotels need particular attention because guests may walk barefoot.
Composite Decking in Desert Climates
Desert projects can experience:
- Intense solar radiation
- Very high daytime temperatures
- Low humidity
- Dust
- Large day-night temperature changes
Very dark decking may become uncomfortable in full sun.
Therefore, lighter shades are often worth considering.
Thermal expansion must also receive attention because the temperature difference between day and night may be large.
Composite Decking in Temperate Climates
In mild climates, surface heat may be less of a concern for much of the year.
However, summer heat waves can still make exposed decking warm.
Therefore, buyers should still consider:
- Orientation
- Shade
- Deck color
- Seasonal use
Composite Decking in High-Altitude Areas
High-altitude locations may have strong solar radiation even when the air temperature is relatively moderate.
Therefore, buyers should not judge surface heat only by ambient temperature.
Solar exposure can still be intense.
Does Humidity Make Composite Decking Hotter?
Humidity affects human comfort but does not necessarily mean the decking itself absorbs dramatically more solar heat.
However, high humidity can make hot weather feel more uncomfortable.
Therefore, a warm deck in a humid tropical environment may feel less comfortable than the same surface temperature in a dry climate.
For hospitality projects, both thermal conditions and user comfort matter.
How Long Does Composite Decking Stay Hot?
The surface usually begins to cool when:
- The sun moves away
- Shade reaches the deck
- Air temperature falls
- Wind increases
- Evening begins
Cooling speed depends on:
- Board mass
- Surface color
- Airflow
- Ambient temperature
- Product structure
- Surrounding materials
A deck surrounded by concrete walls may stay warmer because nearby surfaces also release stored heat.
Does Airflow Help Composite Decking Stay Cooler?
Yes, airflow can help remove heat from the decking surface and the area below the boards.
This does not prevent solar heating, but it can help the deck release heat.
Good ventilation is therefore useful for both:
- Thermal performance
- Moisture management
Why Under-Deck Ventilation Matters
WPC decking should normally have space below the boards for airflow.
If the decking is installed directly over a poorly ventilated surface, heat may accumulate more easily.
Ventilation can help:
- Release heat
- Reduce trapped moisture
- Improve drying
- Support the complete decking system
Therefore, installers should follow the recommended substructure design.
Rooftop Decks Need Special Attention
Rooftops can become particularly hot because they may receive:
- Long hours of direct sunlight
- Reflected heat from walls
- Heat from the roof membrane
- Limited natural shade
For rooftop WPC projects, color and ventilation become especially important.
A light or medium WPC shade may be more suitable than very dark charcoal decking in some hot-climate rooftop applications.
Does the Material Under the Deck Affect Heat?
Yes.
The base below the decking can influence the surrounding thermal environment.
Examples include:
- Concrete
- Waterproof roof membrane
- Soil
- Gravel
- Existing tiles
Concrete and roof surfaces can absorb and release heat.
Therefore, a deck installed above a hot rooftop may feel warmer than the same decking installed in a ventilated garden environment.
Does Deck Orientation Affect Temperature?
Yes.
Decks receiving direct afternoon sun can become particularly warm.
The exact effect depends on geographic location and building orientation.
A deck facing open sunlight may heat more than one shaded by:
- The building
- Trees
- Pergolas
- Adjacent structures
Therefore, project drawings can help buyers evaluate the likely heat exposure.
How Shade Reduces Composite Decking Heat
Shade is one of the most effective ways to reduce surface heating.
Possible shade solutions include:
- Pergolas
- Awnings
- Umbrellas
- Trees
- Roof structures
- Shade sails
The advantage is that shade reduces solar energy before it reaches the board.
This can be more effective than expecting the decking material alone to solve extreme heat conditions.
Natural Shade From Trees
Trees can provide excellent shade for gardens and parks.
However, they also create:
- Leaves
- Pollen
- Organic debris
- Moisture
Therefore, shaded decking beneath trees may require more frequent cleaning.
Thermal comfort and maintenance need to be considered together.
Pergolas and Architectural Shade
Pergolas can be particularly useful for:
- Hotels
- Rooftop terraces
- Restaurants
- Villas
- Poolside areas
Partial shade can significantly improve user comfort while preserving an outdoor appearance.
Is Composite Decking Comfortable for Bare Feet?
It depends on the conditions.
Under mild weather or shade, composite decking can be comfortable for barefoot use.
Under intense direct sunlight, the surface may become too warm for comfortable barefoot walking.
This is especially relevant for:
- Swimming pools
- Resorts
- Residential pools
- Outdoor showers
- Beachfront properties
Therefore, buyers should evaluate barefoot comfort according to the actual climate.
Why Barefoot Comfort Is Different From Material Safety
A board can be structurally suitable for outdoor use but still feel hot to bare feet.
These are separate considerations.
A decking product may perform correctly under sunlight while users still prefer a lighter color or shaded layout for comfort.
Therefore, “outdoor suitable” does not automatically mean “comfortable barefoot at all times.”
How to Choose Composite Decking for Poolside Areas
Poolside projects need to balance several factors.
Buyers should consider:
- Surface temperature
- Color
- Slip-related performance
- Drainage
- Moisture resistance
- UV resistance
- Barefoot comfort
- Cleaning
For highly exposed pools, lighter or medium colors may provide a better thermal experience than very dark colors.
Is Grey Composite Decking Good for Hot Weather?
It depends on the shade.
Light grey and silver grey may absorb less solar heat than charcoal or very dark grey.
Therefore, grey can be a useful modern option for sunny projects.
However:
light grey ≠ cool in every condition
Strong sunlight can still heat the surface.
Is Teak-Colored WPC Good for Sunny Areas?
Teak is often a practical middle option.
It provides:
- Natural wood appearance
- Medium color depth
- Good compatibility with landscaping
- Less visual heaviness than dark brown
For many projects, teak can balance design and thermal comfort better than very dark shades.
Is Charcoal Composite Decking Suitable for Hot Climates?
It can be used, but project conditions should be considered carefully.
Charcoal provides a modern appearance but may absorb more solar heat.
It may still be appropriate for:
- Shaded terraces
- Covered balconies
- Restaurants with awnings
- Cooler climates
- Areas where barefoot use is limited
For completely exposed poolside applications in very hot climates, buyers may prefer a lighter shade.
Does Water Cool Hot Composite Decking?
Water may temporarily reduce the surface temperature.
However, repeatedly wetting the deck should not be treated as the main solution for heat.
Water can evaporate quickly under strong sunlight.
In addition, unnecessary water use is not an efficient long-term design strategy.
A better approach is to use:
- Suitable colors
- Shade
- Ventilation
- Appropriate project design
Can Hot Composite Decking Warp?
Heat alone does not automatically mean the decking will warp.
However, WPC expands as temperature rises.
If the boards are installed without sufficient expansion space, heat can contribute to installation problems.
Possible issues include:
- Board pressure
- Raised ends
- Buckling
- Distortion
- Movement around walls
Therefore, hot-climate performance depends strongly on correct installation.
Thermal Expansion Is Normal
Thermal expansion is a normal physical characteristic of WPC.
It does not mean the material is defective.
The key is to allow enough movement.
Installers should follow the manufacturer’s guidance for:
- End gaps
- Side gaps
- Board length
- Joist spacing
- Installation temperature
Why Long Boards Need More Attention
A longer WPC board can show more total dimensional movement than a shorter board.
Therefore, long-length installations require careful gap planning.
This is especially important in markets with large temperature differences.
Does Direct Sunlight Affect Clips and Fasteners?
The visible board usually receives the most solar heat, but the entire installation system should be considered.
Heat-related movement places demands on:
- Clips
- Screws
- Side grooves
- Joists
The fastener system should allow the board to move according to its design while keeping it properly secured.
How Installation Can Reduce Heat Problems
Good installation does not stop the surface from becoming warm, but it can help the complete deck handle heat more effectively.
Important factors include:
Correct Expansion Gaps
Allow the boards to move as temperatures change.
Suitable Joist Spacing
Provide stable support.
Good Ventilation
Help heat and moisture escape below the deck.
Open Drainage
Prevent moisture accumulation.
Appropriate Board Length
Avoid unnecessary long runs where movement becomes harder to manage.
Correct Clips
Allow proper fixing without restricting intended movement.
Does Composite Decking Cool Faster Than Concrete?
Different materials absorb and release heat differently.
Concrete, stone, wood and WPC can all become hot in sunlight.
It is difficult to make a universal comparison because:
- Colors vary
- Thickness varies
- Surface finishes vary
- Exposure varies
Therefore, buyers should compare actual project materials rather than rely on a simple category claim.
What About Composite Decking vs Ceramic Tile?
Outdoor ceramic tile can also become very hot under direct sunlight, particularly in darker colors.
Again, color and exposure matter greatly.
Therefore, composite decking should not be evaluated in isolation.
The real design question is which material, color and layout provide the best combination of:
- Comfort
- Appearance
- Maintenance
- Drainage
- Installation
- Cost
How B2B Buyers Should Evaluate Composite Decking Heat
Importers and project buyers should ask practical questions before ordering.
1. What Climate Will the Decking Be Used In?
Tell the manufacturer whether the project is in:
- Tropical climate
- Desert climate
- Coastal climate
- Temperate climate
- High-altitude area
This affects product and color recommendations.
2. Will the Deck Be in Full Sun?
A covered balcony has different requirements from an open rooftop.
Confirm whether the project receives:
- Full-day sun
- Afternoon sun
- Partial shade
- Permanent shade
3. Will People Walk Barefoot?
Barefoot use increases the importance of thermal comfort.
This is common in:
- Pool areas
- Resorts
- Residential pools
- Outdoor spas
4. What Color Is Required?
Very dark colors may become warmer.
Therefore, offer lighter alternatives where appropriate.
5. What Surface Technology Is Used?
Confirm whether the decking is:
- Traditional WPC
- 3D embossed
- Capped
- Co-extruded
Do not assume all products behave identically.
6. Is Ventilation Available?
Ask how high the decking will be installed above the base.
Airflow below the deck can improve overall conditions.
7. What Expansion Gaps Are Recommended?
Hot climates require careful installation.
Obtain the correct spacing instructions for the exact product.
Can Surface Temperature Be Tested?
Yes, surface temperature can be measured.
However, test results should be interpreted carefully.
Temperature measurements depend heavily on:
- Air temperature
- Solar radiation
- Test time
- Board color
- Wind
- Surface orientation
- Test location
Therefore, a single surface temperature number cannot represent every real project.
How to Compare WPC Decking Samples in Sunlight
For a practical project comparison, buyers can place physical samples under the same conditions.
Compare:
- Same sunlight
- Same exposure time
- Same location
- Similar sample orientation
Then evaluate how different colors and products feel or measure.
This can help buyers understand relative performance.
However, a small sample is not identical to a complete installed deck.
Why Laboratory Numbers Need Context
Suppose one report says a board reaches a particular temperature.
Without knowing:
- Ambient temperature
- Sun intensity
- Test duration
- Color
- Wind
the number has limited value.
Therefore, buyers should always interpret thermal claims together with the test conditions.
How Distributors Can Sell Composite Decking in Hot Markets
Distributors should avoid promising that WPC “does not get hot.”
A more accurate sales approach is to explain that surface heat depends on project conditions.
For hot markets, distributors can offer:
Light Series
Light grey
Silver grey
Light teak
Medium Series
Teak
Medium brown
Grey-brown
Dark Series
Coffee
Charcoal
Dark brown
Then explain that lighter and medium shades may be more suitable for highly exposed barefoot areas.
This helps customers choose based on application rather than appearance alone.
How Hotels and Resorts Should Select WPC Decking
Hospitality projects need to consider guest comfort.
Important questions include:
- Is the deck beside a pool?
- Is it exposed all day?
- Will guests walk barefoot?
- Is shade available?
- Is the project in a tropical climate?
- What color matches the architecture?
A dark color may look beautiful in a render but become less comfortable under strong midday sun.
Therefore, sample approval under real sunlight can be valuable.
How Restaurants Should Select Composite Decking
Restaurant terraces often use tables, chairs and shade umbrellas.
Because much of the surface may be shaded, darker decking can still work well.
However, exposed circulation areas should be evaluated separately.
Restaurants should also consider:
- Food stains
- Cleaning
- Furniture movement
- Surface heat
- Color
This means capped decking and moderate colors may offer a useful balance.
How Rooftop Projects Should Select WPC Decking
Rooftops are often among the hottest deck applications.
They may receive:
- Direct sun
- Reflected heat
- Strong wind
- Heat from the roof below
For rooftop projects, consider:
- Light or medium colors
- Ventilated substructure
- Shade design
- Expansion gaps
- Suitable fasteners
Heat management should begin during project design rather than after installation.
Common Mistakes When Choosing Composite Decking for Hot Areas
Mistake 1: Assuming Composite Decking Stays Cool
All exposed outdoor flooring can become warm.
Do not promise “cool under the sun” without supporting test conditions.
Mistake 2: Choosing Charcoal Only Because It Looks Modern
Dark decking can look excellent, but it may be less suitable for some barefoot applications.
Mistake 3: Ignoring Shade
Shade can have a bigger impact on comfort than small differences between similar decking products.
Mistake 4: Ignoring Ventilation
A poorly ventilated rooftop deck may retain more heat.
Mistake 5: Forgetting Thermal Expansion
Hot conditions also affect board movement.
Mistake 6: Comparing Test Temperatures Without Test Conditions
Surface-temperature data needs context.
Mistake 7: Assuming Capped Means Cooler
Capping improves surface protection, but does not automatically reduce heat.
Mistake 8: Choosing One Color for Every Market
A popular dark color in northern Europe may not be the best choice for an exposed tropical poolside project.
How to Reduce Composite Decking Heat
Several practical strategies can improve comfort.
Choose Lighter Colors
Light grey, silver grey and medium wood tones generally absorb less heat than very dark colors.
Add Shade
Use:
- Pergolas
- Umbrellas
- Trees
- Awnings
- Shade sails
Improve Airflow
Maintain suitable ventilation below and around the decking.
Match the Color to the Application
Reserve very dark colors for shaded or less barefoot-sensitive areas where appropriate.
Use Landscaping
Plants can provide shade and reduce the visual heat of a hard-surface area.
Consider Project Orientation
Identify where afternoon sun is strongest.
Test Physical Samples
Compare actual product colors under local sunlight before confirming a large project.
Does Heat Affect WPC Decking Color?
Heat and UV exposure often occur together under sunlight.
However, they are different factors.
UV radiation contributes to long-term color change, while heat primarily affects:
- Surface temperature
- Thermal expansion
- User comfort
Therefore, a product can have good UV resistance and still become warm.
Buyers should evaluate both issues separately.
Does Heat Affect WPC Decking Lifespan?
Normal outdoor heat should be considered during WPC product design.
However, long-term performance depends on more than temperature.
Important factors include:
- Material quality
- UV resistance
- Installation
- Expansion gaps
- Drainage
- Traffic
- Maintenance
- Climate
A correctly installed WPC deck can accommodate normal seasonal temperature changes.
Problems are more likely when installation does not allow the board to move correctly.
Frequently Asked Questions
Does composite decking get hot in the sun?
Yes. Composite decking can become warm or hot under direct sunlight. The temperature depends on color, climate, exposure, airflow and product design.
Does dark composite decking get hotter?
Generally, dark colors absorb more solar energy than light colors and may become warmer under similar conditions.
What composite decking color stays coolest?
Lighter shades such as light grey, silver grey and light wood tones generally absorb less heat than very dark colors. However, no outdoor decking remains cool under every condition.
Does WPC decking get hotter than wood?
It depends on the specific materials, colors and exposure conditions. It is not accurate to say that every WPC product is hotter than every type of wood.
Is composite decking too hot for bare feet?
It can become uncomfortable under strong direct sunlight, especially in hot climates and dark colors. Poolside projects should consider lighter colors and shade.
Is capped composite decking cooler?
Not necessarily. Capping improves surface protection, but surface temperature still depends strongly on color and sunlight exposure.
Is hollow composite decking cooler than solid decking?
Not always. Profile structure can affect heat storage, but surface color and direct sunlight usually have a larger influence on barefoot temperature.
Is light grey WPC suitable for hot climates?
Light grey can be a practical option because it generally absorbs less solar heat than charcoal or dark brown.
Does shade make a big difference?
Yes. Preventing direct sunlight from reaching the decking can significantly reduce surface heating.
Does airflow help keep WPC decking cooler?
Airflow can help the deck release heat and supports ventilation below the boards, although it cannot completely prevent heating in direct sun.
Can composite decking warp in hot weather?
WPC expands with temperature. Correct expansion gaps and installation help accommodate this movement. Problems can occur if the boards are installed too tightly.
Can composite decking be used in tropical climates?
Yes. Suitable WPC can be used in tropical climates, but buyers should consider color, UV exposure, heat, ventilation, drainage and installation gaps.
What is the best WPC decking for poolside use in hot weather?
A lighter or medium-colored decking with suitable surface performance, drainage and installation can be a practical choice. The exact product should be selected according to the project conditions.
Conclusion
So, does composite decking get hot?
Yes.
WPC decking can become warm or hot when exposed to direct sunlight, just like other outdoor flooring materials.
However, the level of heat depends heavily on the project.
The most important factors include:
- Color
- Direct sunlight
- Ambient temperature
- Climate
- Shade
- Airflow
- Surface texture
- Deck orientation
- Installation
- Surrounding materials
Dark colors such as charcoal and deep brown generally absorb more solar heat.
Light grey, silver grey, teak and medium tones may provide better barefoot comfort in highly exposed areas.
For hot climates, buyers should also consider ventilation and shade rather than relying only on the decking material.
Poolside, rooftop and resort projects deserve particular attention because users may walk barefoot and surfaces may receive strong sunlight throughout the day.
At the same time, high temperature also affects thermal movement.
Correct expansion gaps, joist spacing and installation design are therefore important for long-term performance.
For B2B buyers, the most useful approach is not to ask for a product that “never gets hot.”
Instead, select a composite decking color and system that matches the actual climate, sun exposure and use of the project.
