Too hot for dogs to be on it during summer?

We understand your concerns regarding deck surfaces becoming warm when exposed to direct sunlight. Similar to other outdoor surfaces, such as concrete, asphalt, sand, or traditional wood decking, composite decking can retain heat depending on weather conditions, sun exposure, and color selection. On particularly hot days, we recommend caution with prolonged surface contact, especially for young children or individuals with special sensitivities. Darker decking colors may absorb more heat than lighter shades, which can influence surface temperature. If your deck sits in direct sun all day, especially in hotter climates, you will notice more surface heat than someone in a cooler region or with partial shade. That’s true for all decking, regardless of material. Warnings about heat can be found on our website at: https://www.trex.com/why-trex/trex-heat-resistant-decking/ General considerations for managing surface heat may include wearing appropriate footwear during warm conditions, utilizing shade elements such as umbrellas or pergolas, incorporating landscaping for natural shade, using outdoor rugs to reduce direct contact, or periodically rinsing the surface with water.
