Can I install my Warmup system directly on top of plywood?

Yes, you can install your Wamup system directly on top of plywood.

 

Since wood functions as a natural insulator, you can install your Warmup floor heating system directly on a plywood sub-floor as long as it is not located above a crawl space.

Of course, using Warmup Insulation Boards, even with a plywood sub-floor, will still improve performance. Ensure that the sub-floor is smooth, dry and free from dust. Visually check that there are no objects on the floor that might damage the heating mat.

This image shows a loose cable system on a wood sub-floor. The installer is using the sleeper method for under hardwood floor installations.

 

Note: If your installation involves having a non-insulated crawl space or garage under the sub-floor, we would recommend the use of insulation boards prior to the installation. This will decrease heat loss in order to increase efficiency.
