On a 35\u00b0C Perth day, the wrong decking board can trigger client complaints before the job is signed off. A dark board around a pool or on a west-facing deck can become too hot to use, putting colour choices, handover dates and your reputation at risk.<\/p>\n\n\n\n

Composite decking for Perth needs more than a timber-look finish. The colour, amount of shade and board build all affect how the deck feels in summer. Here\u2019s what to check before you choose a board for your next project..<\/p>\n\n\n\n

Why Perth Decks Get So Hot<\/h2>\n\n\n\n

Strong sun, clear skies and long hours of exposure heat any outdoor decking. Perth area’s long-term January average maximum is 31.9 degrees C, with 11.6 hours of daily sunshine. A board left in direct sun can reach a much higher surface temperature than the air.<\/p>\n\n\n\n

\"\"<\/figure>\n\n\n\n

That matters for composite decking Perth projects, especially pool surrounds, west-facing patios and decks without a roof. No outdoor board is automatically cool in full sun. Treat heat claims with care unless they come from a fair, stated test.<\/p>\n\n\n\n

Sun and Shade Shape Heat<\/h3>\n\n\n\n

The deck layout often matters more than buyers expect. A dark board under a deep pergola can feel better than a pale board exposed all afternoon.<\/p>\n\n\n\n

Map the site before choosing a colour. Check the deck at 10 am, 1 pm and 4 pm in summer. Note where direct sunlight falls, then plan shade for the busiest outdoor areas.<\/p>\n\n\n\n

Colour Comes First<\/h3>\n\n\n\n

Light colours tend to take in less heat than dark colours. But grain, surface finish and board build can also change how a board feels.<\/p>\n\n\n\n

The best composite decking colour is the one you have tested at the project site. Put like-sized samples in the same sun, for the same time. Compare their surface temperature and touch comfort instead of trusting a screen image.<\/p>\n\n\n\n

Request Free Samples<\/a><\/strong> before you lock in a colour. It is a simple way to avoid a costly change after installation.<\/p>\n\n\n\n

Board Build Can Change Heat<\/h3>\n\n\n\n

A board’s cap, core and profile can affect how it takes in and sheds heat. Yet hollow boards are not always cooler than solid boards, and a thick cap does not prove a cooler surface.<\/p>\n\n\n\n

Only a side-by-side test can show a real difference. Use the same air temperature, sun, wind and test period. If a manufacturer cannot provide thermal data, judge heat comfort from samples rather than a broad heat-resistant claim.<\/p>\n\n\n\n

Composite or Timber in Perth?<\/h2>\n\n\n\n

Composite cuts much of the routine work linked with timber decking. It does not remove the need for good drainage, correct fitting or regular cleaning. Both materials can become hot in full sun.<\/p>\n\n\n\n

LastElegance decking has a listed ASTM D1037 water absorption result of 0.2%<\/strong>. That supports its moisture resistance, but water still needs to drain away from the subframe.<\/p>\n\n\n\n

Timber still suits jobs where natural variation is the priority, and the client accepts regular care. The advantages of composite decking are its minimal maintenance, termite resistance and steady finish over time.<\/p>\n\n\n\n

How Capped Boards Handle UV<\/h2>\n\n\n\n

A capped composite board has a protective outer layer over its core. The cap helps slow staining, weathering and colour fade. It does not make a board immune to Perth’s UV or stop it heating in strong sun.<\/p>\n\n\n\n

\"\"<\/figure>\n\n\n\n

LastElegance uses a 0.8 mm cap with HALS and UV absorbers. Its supplied weathering data records colour change at Delta E <= 4 after 3,000 hours of QUV testing, with slight variation by colour.<\/p>\n\n\n\n

When comparing capped composite decking, ask these simple questions:<\/p>\n\n\n\n

    \n
  1. Is the board capped on the exposed faces?<\/li>\n\n\n\n
  2. What does the fade warranty cover?<\/li>\n\n\n\n
  3. Can I see the colour in outdoor light?<\/li>\n\n\n\n
  4. Is the finish right for the project use?<\/li>\n\n\n\n
  5. Can you send the full product report if the project needs it?<\/li>\n<\/ol>\n\n\n\n

    Test Samples Before You Buy<\/h3>\n\n\n\n

    A site test gives you more useful answers than a showroom display. Run it where the deck will sit.<\/p>\n\n\n\n

      \n
    1. Place each sample in the same direct sunlight.<\/li>\n\n\n\n
    2. Leave them out for the same period, ideally at peak sun.<\/li>\n\n\n\n
    3. Record the date, test time and air temperature.<\/li>\n\n\n\n
    4. Measure surface temperature with the same infrared thermometer.<\/li>\n\n\n\n
    5. Compare touch comfort, colour and finish in full sun and shade.<\/li>\n<\/ol>\n\n\n\n

      Plan a Cooler Outdoor Space<\/h2>\n\n\n\n

      You can reduce deck heat before the boards arrive. Design choices help more than a single product feature.<\/p>\n\n\n\n

      \"\"<\/figure>\n\n\n\n
        \n
      1. Map where the summer sun falls.<\/li>\n\n\n\n
      2. Use lighter colours in exposed outdoor areas.<\/li>\n\n\n\n
      3. Add a pergola, awning or movable umbrella.<\/li>\n\n\n\n
      4. Keep airflow moving below and around the deck.<\/li>\n\n\n\n
      5. Avoid dark boards across an all-day sun zone.<\/li>\n\n\n\n
      6. Test samples before the final order.<\/li>\n<\/ol>\n\n\n\n

        Shade has two gains: it lowers surface heat and makes the outdoor space more usable. Plan it early, before you set board direction and footing positions.<\/p>\n\n\n\n

        Install Composite Decking for Perth Conditions<\/h2>\n\n\n\n

        Composite boards move as temperatures change. The right subframe, gaps and clips give that movement room. They also protect drainage and warranty cover.<\/p>\n\n\n\n

        \"\"<\/figure>\n\n\n\n

        LastElegance recommends 300 mm joist spacing<\/strong>. Use the guide for the exact board when setting end and joining gaps. One gap size does not suit every profile or site.<\/p>\n\n\n\n
