EPS or Expanded Polystyrene Beads are a very effective form of cavity wall insulation. Polystyrene beads are injected into the cavity of a wall with a bonding agent. The beads and adhesive solidify to form an insulating barrier and this significantly reduces the amount of heat lost through your walls (which is how most homes lose the majority of their heat).
The reduction in heat-loss through your walls is dependent on a number of factors including what your walls are made of (brick, stone, concrete blocks etc.) and how wide the cavity is (a wider cavity means a greater depth of insulation).
Heat loss through a wall is measured by its “U-Value” and we would expect the amount of heat lost to reduce by between 65% to 85% with bonded bead insulation.
Because bonded beads have excellent ‘flow’ characteristics substantially fewer drill holes are required when compared with other cavity fill systems.
The fluid nature of the system means that during installation the beads fill voids very effectively meaning it can be suitable for stone cavity walls.
Bonded beads give an excellent combination of price and performance. Installation work can be completed quickly and efficiently with a minimum of disruption.

Because bonded bead insulation will significantly reduce the amount of heat lost through your walls you can expect:
EPS beads have very good thermal properties and are water repellent, they do not rot or decay, and do not provide nutrient value for insects, parasites, or animal and plant life.
The latest EPS Polystyrene bead systems provide an alternative to mineral fibre. The system is fully guaranteed and is covered by either a CIGA guarantee or manufacturer's 25 year warranty.
