It allows various floor finishes to be achieved thanks to a special low stud profile (3mm) that minimises changed in floor levels but still provides an air gap to achieve damp pressure equalisation.
Suitable for new-build or refurbishment projects, it can be used in conjunction with thermal insulation, sound insulation and underfloor heating systems.
Manufactured from virgin high-performance, high-density polyethylene, the membrane is supplied in rolls measuring 20m x 2m, and each roll features a 65mm flat tab on one side to lap and seal sheets.
Other features include good chemical resistance, zero root penetration, rot resistance, and the ability to operate in temperatures ranging from -30oC to +80oC.
A variety of floor finishes can be applied over the sheet. These include T&G wood sheets directly onto the membrane or on joists, 50mm screed, Ardurapid 35 fast drying screed, poured concrete, laminated floors, and old or new stone slabs.
All of these can be upgraded with thermal or sound insulation to conform to Approved Document L and Document E of the Building Regulations.
Delta-FM is also suitable for use on walls, and is just one example from an extensive range of damp problem solutions offered by Delta Membrane Systems.
