Jablite Dynamic Cavity converts the building envelope into a heat exchanger. Ventilation air entering the property is pre-warmed – by heat that would otherwise have escaped from the building.

Jablite Dynamic Cavity wall insulation uses dynamic air flow to increase efficiency and reduce U-values. Air moving through the Jablite Dynamic Cavity insulation recycles heat loss back inside the building.

Construction

• Jablite Dynamic Cavity is designed for use with all forms of masonry cavity wall construction
• There is no need to change the standard wall detailing
• Code 4 U-values can be achieved with a 100mm cavity in a 300mm wall
• Areas of wall not suited to Dynamic insulation can use standard Jabfill (full cavity fill insulation)
• Design and construction literature is available from Jablite Ltd

What differences are there?

• One major change – the improved U-value you achieve!
• You can simply use Jablite Dynamic Cavity in place of other cavity insulation
• Jablite Dynamic Cavity requires a mechanical extract ventilation system within the property to draw air through the cavity
• Improved air quality and reduced condensation risk inside the home

What Code for Sustainable Homes rating can be achieved by using Jablite Dynamic Cavity?

• A Code 4 rating for masonry walls can now be achieved with a 100mm cavity in a 300mm wall thickness.
• U-values <0.14W/m²K can be achieved with a 125mm cavity in a wall thickness of 325mm
• U-values <0.10 W/m²K with a 150mm cavity in a total wall thickness of 375mm.
