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.

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. Look out for the orange membrane – The Vent 3 Air!

The Vent 3 Air; Air open which means it allows more passage of air through the membrane to diffuse moisture build up.

• Cold-pitched roofs – no need for additional ventilation
• No need for the use of vapour control layers
• Extremely breathable
• Watertight technology
• BS 5534 – 345mm batten gauge – zones 1-3 without the need for taping.
• Universal breather for all pitched roof types; warm, cold ventilated and non-ventilated
• Complies with NHBC / LABC guidance

Think Orange, The Vent 3 Air.
