Newton 803 is a high quality damp proofing membrane for use above the ground as an alternative to Newton 803 Newtonite and Newton 805 Newlath where a meshed surface is not required as a surface for direct plastering or rendering, and in order to isolate the wall finish from the damp wall.
Does not require extensive and damaging preparation to the wall surface
Isolation of wall finish from the damp wall
As a damp-proof membrane to isolate the wall finish from the damp wall where a meshed surface for plaster or render is not required.
Newton 803 is available in rolls 1m x 10m = 10m2 (M19) and 2m x 20m = 40m2 (M20)
Newton 803 is typically used where the wall finish to the damp-proof membrane is timber battens, a dry-lining frame or block wall. Newton 803 is 0.5mm thick and has a pattern of raised 3mm studs. The studs face the wall and create air channels that allow for vapour equalisation to take place between the membrane and the wall.
Newton 803 is light, clean and easy to handle. It can be cut with a sharp knife, scissors or shears. The membrane is inert and is highly resistant to water, alkalies, saline solutions and organic acids, and it is not affected by minerals. It is also resistant to bacteria, fungi and other small organisms.
Newton 803 is guaranteed against deterioration for 30 years, and has a life expectancy of at least 50 years (DIN 9001:2000) and is supported by BBA Certification Number 94/3010.
