Damp Proof Membranes

Newton damp proofing membranes are made from inherently stable, high density polypropylene and polyethylene which are very strong yet lightweight materials. Some of the membranes have a mesh thermally welded on the face during the manufacturing process and this provides a key for plastering/rendering.  The stud depth of the membranes ranging from 1-5mm  serves to hold the membranes proud of the surface to which they have been applied creating an air gap.
Newton internal wall membranes use positive vapour pressure to ‘push’ dampness out of the property. Internal vapour pressure in the air gap created by the membranes’ studded formation is greater than the external vapour pressure. The internal pressure moves out to the lower pressure externally thus creating ‘damp pressure equalisation’. In doing so any dampness in the air gap between the external wall and the Newton damp proofing membrane is moved out of the property.
This understanding of how the system works has allowed us in a lot of cases to remove the requirement for ventilation behind the membrane which was believed to be the  way to achieve the best results from the system. However if required and when given  full design consideration ventilation can still be easily introduced.

Newton Damp Proof Membrane - Newlath 2000

Newton damp proof membranes can effectively deal with penetrating damp, rising damp, condensation damp and damp walls.

Newton internal wall membranes use positive vapour pressure to ‘push’ dampness out of the property.

Internal vapour pressure in the air gap created by the  membranes’ studded formation is greater than the external vapour pressure. The internal pressure moves out to the lower pressure externally thus creating ‘damp pressure equalisation’. In doing so any dampness in the air gap between the external wall and the Newton damp proof ing membrane is moved out of the property.

This understanding of how the system works has allowed us in a lot of cases to remove the requirement for ventilation behind the damp proof membrane which was believed to be the  way to achieve the best results from the system. However if required and when given  full design consideration, ventilation can still be easily introduced.
