HeatTrak mats are a popular option for heating outdoor spaces like decks and patios during colder months. The electric radiant heating mats provide a safe and efficient way to add warmth underfoot. However, some homeowners wonder if HeatTrak mats can be used with composite decking materials, or if it’s only suitable for use with traditional wood planks. In this article, we’ll examine if and how HeatTrak mats can be installed with composite deck boards.

What are HeatTrak Mats?
HeatTrak mats are thin, electric radiant heating systems that are designed to deliver warmth directly underfoot. The mats feature thin heating wires encased in fiberglass mesh, providing a uniform heat across the entire mat. The mats feature a low voltage for safety and plug into a thermostat controller. The controller allows you to set your desired temperature and turn the system on and off as needed.
HeatTrak offers several sizes of mats so you can customize the heated area. Mats are available in square footage increments from 10 sq ft up to 100 sq ft. The mats can be trimmed as needed during installation to fit the exact shape and size of your deck or patio.
Benefits of Using HeatTrak Mats
There are several benefits to using HeatTrak radiant heating mats:
- Provide comfortable, even heat directly underfoot
- Allow you to enjoy your outdoor living space longer in colder weather
- Thermostat control allows customization and automation
- Low voltage for safety
- Can be installed under many flooring types
- Zoned heating prevents energy waste
The direct warmth underfoot from the mats allows you to comfortably enjoy your deck, patio or porch even when temperatures drop. The programmable thermostat also makes it easy to customize the temperature and operating times to match your needs.
Using HeatTrak Mats on Composite Decking
HeatTrak mats can be installed beneath most types of decking materials, including today’s popular composite decking. Here’s what you need to know about using HeatTrak with composite deck boards:
Benefits of Composite Decking
Composite decking offers several benefits that make it a popular choice today:
- Durable, long-lasting material
- Requires less maintenance than natural wood
- Resists splitting, cracking, mold, and mildew
- Stain, fade and slip resistant
- Variety of colors and textures available
These advantages have made composite decking a top choice for many homeowners. Adding HeatTrak mats can provide another dimension of enjoyment to your composite deck.
Is HeatTrak Compatible with Composite Decks?
The good news is that HeatTrak mats are fully compatible with composite decking boards. The thin mats are designed to work with any flooring material, wood or composite.
HeatTrak mats produce a gentle radiant heat that warms from below. This type of low-intensity heat will not damage or warp composite boards. You’ll gain all the benefits of HeatTrak warming without any concern about effects on your decking.
Installation Below Composite Boards
Installing HeatTrak mats under composite decking follows a similar process as other flooring types:
- Plan layout – Determine the area you want to heat and required mat size(s). Allow space between mats for expansion gaps.
- Prepare the substructure – Ensure joists and structure are adequate to support mats and decking weight.
- Install mats – Roll out mats over substructure according to layout. Trim mats as needed leaving at least 2 inches between mats and edges.
- Attach mats – Use manufacturer’s recommended staples, tape, or glue to secure mats in place.
- Install wiring – Run supply wire from mats to planned controller location. Mat wires connect in parallel.
- Install decking – Follow decking manufacturer’s instructions to install and gap boards over mats.
- Connect controller – Plug mat power leads into the HeatTrak dual voltage controller.
The mats get installed directly over the joists, under the deck boards. The thin profile doesn’t interfere with deck installation. Just be sure to leave the recommended expansion gaps between mats and at edges. With the mats in place, you can complete your deck installation just like normal.
Tips for Heating Composite Decks
Here are some tips to help maximize the performance and enjoyment of your HeatTrak system under composite decking:
- Allow space for expansion around mats and at edges. Composite decking will expand and contract along with mats.
- Consider zoning your system for larger decks. Divide into separate mats controlled by multiple thermostats.
- Install a moisture barrier over joists before the mats. This protects the system from any ground moisture.
- Run supply wires in conduit from mats to controller for protection.
- Make sure your electrical service can handle the mats’ added load.
- Use a controller with temperature limiting and GFCI for safety.
- Consider a smart controller for automated, customized operation.
With proper planning and installation, you can enjoy cozy, comfortable HeatTrak warmth on your composite deck for years to come.
Cost of HeatTrak Mats
HeatTrak mats represent an investment, but provide many years of enjoyment and use. Here are some average costs:
| HeatTrak Mat Size | Cost (Mat Only) |
| 10 sq ft mat | $130 |
| 20 sq ft mat | $260 |
| 40 sq ft mat | $520 |
