Sarnafil Single Ply Roofing Membranes

Sarnafil roofing membranes are very versatile and therefore ideal for almost any kind of roofing project from new extensions, to replacement or refurbishment of existing roof coverings, to bay windows and garages.

Quality Membranes
Sarnafil PVC membranes are manufactured in Switzerland, a country renowned for quality.

Dimensionally Stable
Sarnafil membranes are dimensionally stable due to the reinforcement carrier sheet. This means that they do not shrink, stretch or lose their shape.

Solar Reflective
Membranes are UV resistant and need no chippings to protect them from the sun’s UV rays.  Sarnafil membranes are tested for UV ageing to the highest international standard for waterproofing membranes, a test which requires exposure to 5,000 hours of UV testing. While this is a tough test in itself, Sarnafil membranes are tested to withstand 10,000 hours of UV exposure.

Sarnafil membranes have a unique lacquered top coating, the benefit of which is that it helps to provide better resistance to industrial/biological waste and air pollution.

Resistant to Root Growth
Membranes are resistant to root growth, making them suitable for use under green roofs.

Fire Retardant
Sarnafil PVC membranes are treated with a fire retardant and are self-extinguishing. The membranes can be used to achieve the relevant Building Regulations approval.

Vapour Permeable
As Sarnafil membranes are vapour permeable, small amounts of moisture trapped beneath the membrane is able to evaporate, preventing blistering or slumping as can be common in traditional flat roofs.

Flame Free
Sarnafil membranes are cold applied and free from naked flames. Our membranes are homogenous, which when hot air welded form joints which are stronger than the membrane itself.

Along with compliance with an ISO 14001 Environmental Management System, Sarnafil membranes have a low environmental impact and when used in conjunction with a high performance thermal insulant can improve the energy performance of your home.  Sarnafil PVC membranes have been used to obtain Ecopoint profiles and BRE Green Guide ratings for membrane roofs, a rating which can be used to obtain credits towards an overall environmental rating for a building (BREEAM).

Life Expectancy
In a competitive sellers market, investing in improving or replacing your roof can reap dividends.  Sarnafil roofing membranes have been independently assessed by the British Board of Agrement (BBA) and are certified, in their opinion, to have a life expectancy ‘in excess of 40 years’.
