Cavity Wall Insulation Polystyrene Bead

Cavity walls over 225mm can be accommodated with the input of an engineer and are project specific.

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. The bonded bead significantly reduces thermal transmittance across the cavity. Thermabead cavity wall insulation are industry leaders in providing high performance injected blown bead insulation systems. Kore fill cavity wall insulation is expanded polystyrene eps injected in bead form into a wall cavity to form an insulating mass.

There are two other materials commonly used for cavity wall insulation bonded polystyrene beads and foam. This method of cavity wall insulation consists of pre formed polystyrene beads which are usually combined with a binding agent or adhesive and then injected into the cavity space between the outer and inner masonary work. 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. The bonding agent is used to provide long term stability to the insulant.

The use of polystyrene bead for cavity wall insulation does not prejudice the fire resistance properties of the wall. This makes kore fill the perfect solution to meet nzeb part l 2019 cost effectively. What is expanded polystyrene bead. Neither material is used as widely as mineral wool fibre because of cost.

The polystyrene bead can be injected into spaces other insulation materials might not be suitable for such as. Any rainwater penetrating the outer leaf will drain harmlessly to the footings. If properly installed these materials should theoretically be superior to mineral wool fibre as they are inherently waterproof. The cavity wall insulation solidifies in the cavity as it is injected along with a special bonding agent adhesive glue.

Platinum silver bead cavity wall insulation is expanded polystyrene eps injected in bead form into a cavity to form an insulating mass. Ciga cavity insulation guarantee agency issue an independent 25 year. The material is resistant to water penetration and will not transmit water across the cavity by capillary action or from below dpc level. With outstanding cavity wall insulating properties it is ideal for domestic commercial and industrial use.
