Do you have composite decking? Wood-plastic composites have become widely accepted for building residential decks due to their long lifespan and low-maintenance qualities. Because they’ve become more common, we’re frequently asked whether our snow melting mats can be used on composite decking.

Today, we’re going to answer this question in-depth but, first, we’ll dig into some background on composite materials and how they work. Let’s get started!


What are composite decks?

Building decks from composite materials has become an increasingly popular option for homeowners because of their advantages over wooden decks. Traditional wood decks are stunning but they can become a lot of work to maintain over time. Plus, they have to be resealed and stained every 2-3 years.

On the other hand, composite decking is low-maintenance, durable, and customizable. This makes it an attractive decking option for homeowners who want to get the most out of their deck’s lifespan.

There are several types of composite decking. These materials include PVC, polymer, laminate, and others. Trex is a common brand name. Basically, if your deck is made of faux-wood, you have composite decking.

Can I use heated floor mats on my composite deck?

The short answer is yes. It's perfectly fine, and the heat is not a problem at all for decks made from composite materials.

There is zero concern for using snow melting mats on composite decks. You don’t need to use a thin layer of plywood or carpeting underneath your heated snow melting mats. Nor do you need anything underneath the composite decking because the heat is not going to affect it.

However, we recommend that you don’t put snow melting mats on brand new composite decking. If it's a brand new composite decking, you should let it fade for a few months and then put the HeatTrak mats out. Otherwise, our mats (or any mats, for that matter) will block the sun and your deck won’t fade evenly.
