Imperial Bead Cavity Wall Insulation 

The Imperial Bead cavity wall insulation system is an injected expanded polystyrene (EPS) bead bonded with an adhesive designed for multiple cavity wall scenarios including masonry, party wall & timber frame. 

It needs substantially fewer drill holes when compared to other cavity fill products & can be completed quickly & efficiently with a minimum of disruption.

Bonded beads give an excellent combination of price and performance & provides an alternative to mineral fibre insulation.

EPS beads have very good thermal properties and are water repellent, they do not rot or decay and do not provide nutrient value for insects, parasites or rodents.

The system is fully covered by an insurance backed guarantee provided by Quality Mark Protection & the manufacturer’s 25 year warranty.

The system will not allow water to cross the wall construction. The beads themselves allow for the safe dispersal of any water. The gaps that naturally occur between the spherical beads allow any water to drain down freely to the ground, rather than across to create damp problems on inside walls.

The structure of the installed blown bead allows the cavity to retain the ability to breathe with the cavity wall insulation in place.
