What is Jablite Dynamic Cavity?
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?
- There aren’t many differences but there is one major change – the improved U-value you achieve!
- You can simply use the Jablite Dynamic Cavity insulation 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 (<0.19W/m2K) 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.
How does it work?
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.
