What are the key qualities of breathable roof membrane? Our breathable roof membrane option offers a variety of qualities including:

• Breathable membranes are a fundamental element of most new build and refurbishment projects. Their adaptable, multi-purpose use is seen by specifiers, merchants and installers as the optimum solution to under-slating requirements.

• Breather membranes play a key role in protecting buildings and occupants from the elements. In addition to improving energy efficiency, this breather membrane offers long-lasting protection against several threats to building integrity, including condensation and infiltration by water and air. Our Heavy Duty 120 g/sm breathable roof membrane is of equivalent quality but offers a much more cost effective alternative to branded membranes like Cromar and Tyvek.

• This type of roof membrane contains special stabilisation additives which extend its resistance to UV radiation which allows installers to perform assembly of the final roof covering without the added pressure of time-delays affecting the material’s durability.

• Breathable roof membrane is equally suitable whether draped unsupported over rafters or laid directly over insulation. The outer layer forms a functional waterproof surface, the middle layer is the breathable waterproof membrane and the inner layer protects the membrane from abrasion and damage, also giving additional strength. This enables the fabric to allow moisture vapour to pass through, whilst remaining fully waterproof.

What are the main applications of breathable roof membrane?

When it comes to the application of breathable roof membrane, it is ideal for:

• Engineered for use in a fully supported or unsupported tiled, slated or metal roof system.

• Transporting moisture resulting from any ingress through a primary roof covering into a roof drainage system

• Provide a barrier to minimise the wind uplift load acting on the slates or tiles

• Provide a secondary barrier to the ingress of wind driven rain, snow and dust

• Provides robust weather protection before the installation of the primary roof covering

• EU approved for use in Warm and Cold, Ventilated and Non Ventilated Roofs

• Available in a 1.5m width as standard to conform easily to any typical roof configuration or the individual working practices of the installer

• This is a water vapour permeable membrane with a mass of 120gms suitable for use in all types of
  domestic and commercial roof applications.
