This is one of the most efficient and effective ways to utilize radiant heat in your building. The system of pipes is laid out on the subfloor and a thin layer of a lightweight concrete called gypcrete is poured over the system. Typical floor coverings are then laid over the gypcrete. This method allows for all the benefits of a solid thermal mass, but with quicker response times in the changes in heating.
With its smaller mass, a gypcrete installation is more versatile in where it can be applied, as compared with concrete. It is a great installation method to choose in your radiant project.
