Many people are confused over the choice between Warmboard and a staple up radiant heating system. This article should help to set you straight.
A Warmboard system combines a structural subfloor with a complex radiant panel into one straightforward radiant heating system. Its basically a strong, broad, weather-resistant, 4′ X 8′ sheet of plywood, with a series of channels cut into the top plane and a thick sheet of high-grade aluminum, which is permanently bonded to each panel. The aluminum is highly conductive. In fact, its about 30% more conductive than most common alloys, but it also cools down quickly.
Warmboard replaces the normal structural subfloor. It can be cut, nailed or screwed directly to your floor joists just like any conventional subfloor.
Most Warmboard systems function with water ranging in temperature between 90 and 110, however if you are considering a wool carpet, or another high resistant floor covering, you can easily raise your water temperatures and still operate your heating system efficiently.
Warmboard also have two important properties – they have high conductivity and low thermal mass, which means...
