Retaining Heat

All outdoor products face continual heat in the summer.  The sunlight beams down for hours and most materials get hot.  Old above-ground pools for instance, usually had some sort of deck that would burn up in the sun by mid day.  Do you remember the uncomfortable walk from the steps to the pool if the metal deck was dry?  Even wood decks retain heat.  Aside from concrete and grass, it’s hard to find barefoot relief.

Composite Improvements

Heat build up was one of the original composite deck problems.  Since its first generation, composite has come along way.  Companies listen to their buyers and work to produce improved products year after year.  One solution to heat retention is the capped outer layer.  Capped composite features a protective coating bonded during the manufacturing process.  The capped coating contains UV inhibitors that make the decking more heat resistant.


Color Matters

Even wood decking get hot after hours of direct sun exposure.  One proven solution to reduce heat retention on decks is to stick with lighter colors.  Studies show that color is the most contributing factor to the amount of heat retained in a material.  Just think about it; black asphalt is always much hotter than white concrete.  Darker colors, regardless of material, will always absorb the heat.  Whereas, lighter colors do better to reflex heat.  Fortunately, composite comes in a large variation of decking colors from multiple brands.  If your backyard gets more than the usual amount of sunlight, consider choosing a light gray or light brown colored decking to reduce the risk of heat retention.  For yards with lots of tree shade, the medium to dark colors are ok.
