Manufactured in Limerick, Envirobead is pumped into the cavity through a series of holes in accordance with a drilling pattern specified by the National Standards Authority of Ireland (NSAI).

The holes are drilled from outside to avoid disruption to your home. These holes are about 25mm in diameter (the size of a €2 coin), which are made good to match the existing finish of your home on completion.

Adhesive is added at the point of entry, forming a wall of insulation. Installed under pressure, the mixture flows like a liquid, completely filling every part of the cavity. Once set, any moisture entering the cavity simply rolls down the outside of insulation to the base of the cavity preventing dampness.
