Composition and manufacture
Delta®-PT is a high-performance polyethylene membrane, extruded into a series of studs to create a continuous air gap behind the waterproof membrane. This results in a watertight, temperature- and chemical-resistant seal. The Delta®-Lath membrane has a mesh incorporated on the internal face, attached by a thermic welding process in manufacture. The welded mesh allows for direct render, plasters or DAB-fixed plasterboard for internal applications. Delta®-FM is specifically designed for floor applications. It is manufactured using high-performance, high-density polyethylene, with a low-stud profile allowing floor finishes to be applied, whilst also providing an air gap to achieve damp-pressure equalisation.
Size and weight
Delta®-Lath: stud height: 8mm; overlap detail: 100mm; roll sizes: 1,500 x 10,000mm. Direct rendering grade available in clear 2,000 x 20,000mm or 1,500 x 10,000mm.
Delta® membrane systems can be used externally as a waterproof support for rendered finishes, especially in exposed situations. Delta® render can also be applied to give a decorative finish which will not require painting.
Delta® systems are installed by a nationwide network of specialist contractors. Contact manufacturer for details.
Cleaning and maintenance
Delta® membrane systems are supplied with a 30 year product guarantee, covering the membrane and ancillary components. The Delta Membrane Systems range is certified to the requirements of BS EN ISO 9001.
