BBA Agrément Certificate
Certificate type
Meshed damp proofing membrane.
Can be used as the following:
Newton 803 Newtonite is a composite damp proofing membrane, comprising of a high density polyethylene membrane with a rot-proof polythene mesh heat-welded during the manufacturing process to the surface of one side. The meshed surface creates a mechanical key to allow the membrane to be plastered, rendered or to receive dot and dab plasterboard.
Newton 803 Newtonite is 0.5 mm thick and has a pattern of raised 3 mm 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 Newtonite is light, clean and easy to handle.
Newton 803 Newtonite is guaranteed against deterioration for 30 years, has a life expectancy of at least 50 years, and is supported by BBA Certification Certificate Number 94/3010.
Consult manufacturer's literature for relevant surface preparation information, for protection of the coating once applied and for recommended finishes.
