Cromar launches Vent 3 Air

Over the past 18 months we at Cromar have been working tirelessly to develop a breather membrane that is not only affordable to a diverse market but also technically superior with its performance with being both air open and vapour permeable.

FINAL VENT3 AIR On the roof

When the NHBC issued the revision to Part L Section 7: Air permeability and pressure testing, this meant a change for both membrane manufacturers as well as the contractors on site. The introduction of a minimum level of air permeability within a dwelling which is outlined in section 7 brought a need for better performing breather membranes within the roof space. The build-up of interstitial condensation can (more commonly in the winter months, or during the drying out period of a build) be a problem to contractors and home owners and evidently have an effect on the build itself.

This was more prominent in unsupported cold roof applications where there was a natural environment for moisture, meaning a membrane accompanied by additional mechanical ventilation particularly at ridge level was recommended, we believe we have a solution without the need for additional ventilation.

The NEW Vent 3 Air breather membrane ticks all the boxes for specifiers, distributors and contractors alike. The membrane has excellent air permeability, vapour resistance and water tightness properties. We will be heading off in to the market with this product this November, look out for the orange membrane – The Vent 3 Air.

Think Orange, The Vent 3 Air.
