Austech External Building Products offers the Foamular extruded polystyrene insulation for use in concrete sandwich panels during construction.

Concrete is highly popular among building materials because of advantages such as durability, indestructibility, ease of use and high thermal mass. Concrete on its own though, is an inadequate insulation system.

Austech’s Foamular extruded polystyrene insulation can meet the shortcomings of concrete by providing superior thermal properties and increasing the overall thermal value while maintaining construction efficiencies.

Foamular extruded polystyrene insulation will help improve the performance of walls as well as meet the BCA part J construction requirements.

The extruded polystyrene insulation is sandwiched between two concrete layers held together by non-conductive connector ties, which minimise the energy-draining effects of thermal bridging.

Key advantages of Austech’s Foamular extruded polystyrene insulation:

Consistent temperature on the inside will eliminate need for artificial cooling and heating
Regulated temperature passively created through the superior thermal mass forms a pleasant inner environment
Saves costs on artificial temperature control devices such as air conditioning systems

Buildings insulated from the inside without the ability to take advantage of thermal mass require artificial temperature controls such as air conditioning to work harder against the conditions and exert higher energy levels.

A comparison of the insulation values of concrete wall panel systems shows that while just 50mm of Foamular has an R value of R1.78, 110mm of brickwork achieves R0.18 and a 100mm concrete slab achieves just R0.069.

Foamular extruded polystyrene wall insulation has been used extensively in several precast insulated concrete sandwich wall panel systems.
