Wall Installation

Wall Installations

Expanded Polystyrene (EPS) Insulation when installed is effective in reducing the transmittance and sound insulation in building construction.

Typical installation details

Cavity load-bearing wall of 28eps_cavitywallbearing0mm thickness, with an unbroken 25mm expanded polystyrene insulation pressed against the inner leaf of the cavity wall.

The face brick leaf is 50mm away from the insulation, which serves to prevent heat transfer by conduction and to allow for condensation which eventually drains out through the weep holes.






In the construction business, EPS sheets and boards are used for thermal and sound insulation in wall, roofs and on floors, while loose beads can be used as an aggregate in lightweight concrete, plasters and renderings. Other uses include underfloor heating systems, drainage boards, permanent formwork, foundation and pre-fabricated wall.





EPS is compatible with cement, concrete, brick, masonary, mortars, plaster and bitumen based damp proof membranes. EPS is rot proof and durable. When installed as recommended, EPS will remain effective as an insulant for the life of buildings and structures.
