Cavity Wall Insulation Polystyrene Bead

The main materials used by nia installers are mineral wool glass or rock wool eps bead polystyrene bead and pu foam polyurethane foam cavity wall insulation can lower your heating bills lower wear and tear on your boiler and reduce global warming and climate change.

Cavity wall insulation polystyrene bead.

The polystyrene bead can be injected into spaces other insulation materials might not be suitable for such as. The bonding agent is used to provide long term stability to the insulant. The material is resistant to water penetration and will not transmit water across the cavity by capillary action or from below dpc level. The bonded bead significantly reduces thermal transmittance across the cavity.

Neither material is used as widely as mineral wool fibre because of cost. Kore fill cavity wall insulation is expanded polystyrene eps injected in bead form into a wall cavity to form an insulating mass. We use graphite 27 plus cavity wall insulation beads which consists of an expanded polystyrene material in bead form which is injected into the wall along with a bonding agent. If properly installed these materials should theoretically be superior to mineral wool fibre as they are inherently waterproof.

Polypearl is injected as individual eps insulation beads which then form a consistent matrix inside the cavity using an adhesive to hold them in place. Ciga cavity insulation guarantee agency issue an independent 25 year. The thermo efficient qualities of custompac polystyrene bead make it a versatile wall cavity insulation material. Thermabead cavity wall insulation are industry leaders in providing high performance injected blown bead insulation systems.

The cavity wall insulation solidifies in the cavity as it is injected along with a special bonding agent adhesive glue. Providing 100 cavity fill with no cold spots no waste and easy to install. For the safety of our customers our standard bead polystyrene cavity wall insulation is manufactured with a flame retardant additive and tested to bs476 part 12. There are two other materials commonly used for cavity wall insulation bonded polystyrene beads and foam.

With outstanding cavity wall insulating properties it is ideal for domestic commercial and industrial use. Cavity walls over 225mm can be accommodated with the input of an engineer and are project specific. 1991 approx bead size inches mm. Any rainwater penetrating the outer leaf will drain harmlessly to the footings.
