With summer around the corner and deck season beginning, customers often ask us, “how much hotter is composite decking than treated wood?” We also get asked, “if I go with a darker wood stain, will it be a lot hotter on the deck?” These are all very good questions.
The more pigment that’s in the stain, the more protected from the UV rays the deck will be. But how much hotter is that darker color? And how much hotter is PVC decking versus Ipe hardwood or treated pine with a dark stain? We carry a large range of high quality decking and exterior stains. We decided to put them to the temperature test. Granted, in April your lucky to get an 86 degree sunny day with just a light scattering of thin clouds. So that’s the day we picked. But even in these conditions, all of the decking materials we tested were over 100 degrees in temperature when left all day in the full sun.
The temperature of your deck in the hot sun is only one factor to consider while picking out a quality decking material or stain, but can be an important factor depending on the location. So here are some things to consider while deciding what stain to pick out or which type and color of decking materials to put down. What side of the house is your deck or porch on? Will it have any shade during the day? Does it get more sun in the morning or afternoon when the sun’s UV rays are more intense? If you answered full sun with little to no shade, you may want to consider a medium to light color regardless of the decking material you pick out. To compliment, a darker color can be used on the deck band, as a border, accent or railings to a lighter deck. Other ways to keep your deck cooler would be putting up a lattice privacy panel on the southern side of your deck or adding an arbor above to provide shade on the deck surface during the day.
Although composite and pvc decking does get hotter than treated decking at the temperature tested, a lighter color of the man-made decking comes close to the same temperature as a darker color on the treated stained wood for the 86 degree day tested.
While performing this test, we did notice the temperatures of the different decking materials and colors effected temporarily by a few degrees when a stray cloud went by or a light breeze came through the area. We attempted to keep the conditions the same on all tests performed.
We hope this article helps answer some of the questions regarding the temperatures of decking.
