The Warmup Forte Grid System is designed for installation into load-bearing structural floors. It incorporates wire grids to which the underfloor heating pipework is attached using cable ties.

The Warmup Forte Grid System is either located within a concrete or structural screed, but is suitable for almost any floor finish, in particular where the flooring is for a commercial application, such as epoxy paint or resin.
