Polystyrene Bead Cavity Wall Insulation

The material is resistant to water penetration and will not transmit water across the cavity by capillary action or from below dpc level.

Polystyrene bead cavity wall insulation.

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. Another application in construction for polystyrene beads is retrofit insulation of un insulated exterior walls. 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.

If properly installed these materials should theoretically be superior to mineral wool fibre as they are inherently waterproof. With outstanding cavity wall insulating properties it is ideal for domestic commercial and industrial use. 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. Any rainwater penetrating the outer leaf will drain harmlessly to the footings.

There are two other materials commonly used for cavity wall insulation bonded polystyrene beads and foam. 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. The thermo efficient qualities of custompac polystyrene bead make it a versatile wall cavity insulation material. The bonding agent is used to provide long term stability to the insulant.

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. Providing 100 cavity fill with no cold spots no waste and easy to install. Thermabead cavity wall insulation are industry leaders in providing high performance injected blown bead insulation systems. If the puffed beads fill the cavity the space can obtain r values close to that of fiberglass insulation.

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.
