Cavity Wall Insulation Beads

With outstanding durability water resistant and rot proof our bead product is the number one choice for insulation.

Cavity wall insulation beads.

To fill a cavity wall one uses 4 types of insulation. Cavity wall insulation with e p s. 20 more efficient than rock and glass wool. Providing 100 cavity fill with no cold spots no waste and easy to install.

The cavity wall insulation solidifies in the cavity as it is injected along with a special bonding agent adhesive glue. The cavity insulation guarantee agency provides independent 25 year guarantees for cavity wall insulation fitted by registered installers. Bonded bead insulation is a system of injecting external cavity walls with graphite polystyrene beads and a bonding agent. There are two other materials commonly used for cavity wall insulation bonded polystyrene beads and foam.

The cavity insulation guarantee agency was established in consultation with the government to provide householders with an independent uniform and. Glass wool rock wool eps beads and foam. This is due to the capillary action of the bead allowing gravity to draw any moisture present down the inner surface of the outer leaf to drain away at foundation level. Polystyrene beads should not be used in wall cavities where they could come into contact with electrical wires.

Platinum silver bead cavity wall insulation is expanded polystyrene eps injected in bead form into a cavity to form an insulating mass. A popular method of insulating new build cavity walls is to fill the gap in between the two leaves either by pumping them with eps beads or by adding rigid board insulation. If properly installed these materials should theoretically be superior to mineral wool fibre as they are inherently waterproof. Each material has its own price and specific properties.

The bonded bead significantly reduces thermal transmittance across the cavity. The beads and adhesive combine to form an insulating barrier which significantly reduces the amount of heat lost through the walls. New vermiculite insulation is typically safe and free from asbestos. Cavity wall insulation involves the injection of a suitable insulant using a specified and approved system designed to ensure a complete fill of the cavity wall area.

Thermabead cavity wall insulation are industry leaders in providing high performance injected blown bead insulation systems. Neither material is used as widely as mineral wool fibre because of cost. Cavity wall insulation beads will not allow dampness or moisture to penetrate the cavity in a properly constructed wall.
