DELTA®-FM is specifically designed for floor applications to combat dampness and contamination. The special low stud profile (3mm) minimises changes in floor levels but still provides an air gap to achieve damp pressure equalisation.

The membrane is a fast-track application that allows various floor finishes to be achieved with zero ‘down time’. The % R.H. levels are isolated in the air gap, and controlled. DELTA®-FM can be used in new build, remedial or refurbishment projects for floors, and walls.

DELTA®-FM can also be used in conjunction with Thermal installation, sound insulation and many types of underfloor heating systems.
