Cavity Wall Insulation

Hich Cavity Wall Insulation

Connolly Insulation are registered installers of ‘EnviroBead’ bonded bead for cavity wall insulation.

EnviroBead easily meets the required U value of 0.21 in the walls of newly constructed properties (150mm cavity).  



The beads, similar to what you would see in a beanbag, arrive by truck to your home. Our trained installers blow these beads trough pre-drilled small injection holes. As the beads pass through the injection nozzle, they are coated with an adhesive which allows the beads to flow easily before bonding together forming a solid Insulation mass within the cavity. EnviroBead is totally safe to use in both new and existing houses, whether constructed with block or bricks and even in areas exposed to driving rain.

EnviroBead is approved by Irish Agreement Board as a cavity wall insulating material. Registration Number 07/0293
