Single Ply Roofing Membranes

What Is Single Ply Roofing?

Single Ply roofing membranes have been used for covering flat roofs for more than 30 years in the UK and are the choice of many of the country’s leading architects, be it new build or refurbishment.

Single ply membrane is usually composed of a synthetic polymer. As well as being very strong and flexible it also provides continuous waterproofing and insulation.

Because of its flexibility a single ply membrane can be applied to any shape of roof giving quick construction, easy maintenance and repair.

Benefits Of Single Ply Roofing

Single-ply systems have many benefits over more traditional materials, such as:

  • cold applied (no flame)
  • excellent weather resistance proven in all climates
  • expected lifetime of over 30 years
  • no major maintenance or repair required during life
  • extensive, insurance backed warranty
  • up to 15 times greater vapour permeability
  • greatly reduce or eliminate condensation
  • materials maintain their outward appearance
  • strength, dimensional stability and UV resistance
  • wide range of colours
  • no interior building access required

Liquid Waterproofing

What Is PMMA Liquid Resin?

PMMA stands for Poly(methyl methacrylate) it is a fast curing acrylic resin. The Wecryl waterproofing system we use by Westwood is a seamless, crack-bridging and joint-bridging waterproofing system that is able to withstand mechanical stresses. It contains a highly flexible and fleece-reinforced waterproofing layer as well as abrasion-resistant system layers for vehicle and foot traffic. The waterproofing system’s liquid application and high bonding strength on almost any substrate also allow breakthroughs and upstands to be integrated securely and seamlessly. These properties make the system a cost-effective solution for car parks and balconies, especially for refurbishment projects.

Benefits Of PMMA Liquid Resin

• Seamless waterproofing layer with fleece reinforcement.
• Fully bonded to the substrate, therefore no flow paths for water.

• Can be applied to almost any substrate.
• Liquid application ensures seamless incorporation and secure waterproofing of the most complex upstands.
• Unlimited design options (colour finish, tiled look, road markings etc).
• Easy and fast application.

• Can also be applied at sub-zero temperatures.
