Polystyrene Bead Cavity Wall Insulation

In 2006 polypearl designed and developed the polypearl platinum bonded bead system which has graphite added to the polystyrene beads to improve their energy saving qualities and they are very pleased to say the unique system has quickly gained universal recognition as being the best cavity wall insulation that money can buy.
Polystyrene bead cavity wall insulation. 1991 approx bead size inches mm. Neither material is used as widely as mineral wool fibre because of cost. In this application the puffed beads are poured into the wall cavity between the studs by drilling a hole in the top of the wall. 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.
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. The polystyrene bead can be injected into spaces other insulation materials might not be suitable for such as. The use of polystyrene bead for cavity wall insulation does not prejudice the fire resistance properties of the wall. The bonding agent is used to provide long term stability to the insulant.
Benefiting from the excellent thermal values of eps ecobead platinum is a full fill cavity wall insulation supplied by a network of approved installers quick and easy without any waste. Providing 100 cavity fill with no cold spots no waste and easy to install. The material is resistant to water penetration and will not transmit water across the cavity by capillary action or from below dpc level. Another application in construction for polystyrene beads is retrofit insulation of un insulated exterior walls.
Thermabead cavity wall insulation are industry leaders in providing high performance injected blown bead insulation systems. There are two other materials commonly used for cavity wall insulation bonded polystyrene beads and foam. Any rainwater penetrating the outer leaf will drain harmlessly to the footings. With outstanding cavity wall insulating properties it is ideal for domestic commercial and industrial use.
The thermo efficient qualities of custompac polystyrene bead make it a versatile wall cavity insulation material.
