Does it make sense to put SunTouch under carpet, Laminate or Wood?
In some cases, yes. It is all about your comfort. The largest SunTouch installation was almost 8,000 Sq feet under carpet, right here in Sunny Southern Calif.

For many people, carpet is a way to avoid the discomfort of cold floors, which is a problem that SunTouch can solve for any type of floor covering.
