Mesh Membrane 20m²

Newton 503 Mesh is a meshed damp proof membrane for use either internally or externally. With its 3mm stud, Newton 503 Mesh is just over 3.5mm in overall thickness, and is the preferred meshed damp proof membrane where space is of a premium. Its high quality meshed surface provides an excellent 'key' for lime mortars, renders, plasters or dabbed plasterboard.

The damp proof membrane, Newton 503 Mesh has a life expectancy of at least 50 years (DIN 9001:2000). Newton 503 Lath is inert with high pressure stability. It is highly resistant to water, alkalise, saline solutions and organic acids, and is not effected by minerals. It is also resistant to bacteria, fungi and other small organisms.
