Fire-rated breather membranes you need to know about

Two newly developed products exceed current fire safety regulation levels for high rise and high risk buildings, while providing structural and weather protection

In association with
Partel Exoperm Duro A1 and Exoperm Mono Duro A2 membranes are designed for use in high rise and high risk buildings.
Partel Exoperm Duro A1 and Exoperm Mono Duro A2 membranes are designed for use in high rise and high risk buildings.

Partel, a manufacturer of airtight and windtight membranes, has developed two new fire-rated breather membranes.

Exoperm Duro A1 and Exoperm Mono Duro A2 high-performance membranes are designed to achieve the highest levels of fire performance, while protecting the building structure by allowing vapour to diffuse from within the structure towards the exterior. This prevents ‘thermal bypass’ of external air through the insulation and performs the secondary task of weather protection.

Suited to offsite and onsite construction, residential or commercial projects, Exoperm Duro A1 and Exoperm Mono Duro A2 are fully independently certified and tested in accordance with BS EN 13501-1.

The membranes are compliant with Document B Fire Safety and are suitable for use in a range of external wall types, especially in high rise buildings or those that pose a greater risk of fire safety.
