Our Buildings are constructed with Structural Insulated Panels (SIPs). SIPs were first developed in 1950 in the US and have undergone continual improvement ever since. The panels currently comprise sheets of fibre-cement bonded to both sides of a thick, rigid, fire-retardant insulating core of expanded polystyrene. SIPs floors are supported by steel floor framing. The walls have steel posts integrated into them for additional strength, ideal for load-bearing walls. Roofs are made with colorbond steel corrugated roofing bonded to the top of long-span panels, which are much more efficient and cost effective than conventional methods.The panels are:

Strong and Lightweight

Extremely thermally efficient (reducing air-conditioning costs)


Quick to erect


Waste is reduced since the panels are pre-built to high precision in the factory using computer-controlled equipment. In-country manufacture of the panels supports local supply industries, generating jobs.
