PARTEL DEVELOPS TWO NEW FIRE-RATED BREATHER MEMBRANES

Partel, a leading manufacturer of airtight and windtight membranes, has developed two new fire-rated breather membranes that exceed current fire-safety regulation levels for high-rise and high-risk buildings –EXOPERM DURO A1 and EXOPERM MONO DURO A2.

The high-performance membranes are designed to achieve the highest levels of fire-performance while also protecting the building by allowing vapour to diffuse from within the structure towards the exterior, preventing ‘thermal bypass’ of external air through the insulation, and performing the secondary task of weather protection.

Suited to offsite and on site construction, residential or commercial projects, EXOPERM DURO A1 and EXOPERM MONO DURO A2 are fully independently certified and tested in accordance with EN13501-1. 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.

EXOPERM DURO A1 is noncombustible and suitable for use on closed joint facades. Alongside fire performance, EXOPERM DURO A1’s technical attributes ensure long-term protection of the assembly, with a highly vapour open Sd value of 0.03 m, along with resistance to water penetration and dimensional stability.

EXOPERM MONO DURO A2 is an innovative airtight yet vapour permeable facade membrane, based on Monolithic Technology. This is Class A2-s1,d0, guaranteeing limited- combustibility, absent or very limited smoke emissions, and no burning droplets. It is suitable for use on open or closed joint facades and balances airtightness, moisture management and secondary weather protection with fire performance.
