Insulated Modular Building System

Versipanel is a structural insulated wall system, offering an insulated core with the strength of a hidden 90mm x 45mm timber internal framing system.

The Versipanel can be manufactured with a combination of fibre cement or oriented strand board skins to satisfy your desired finish, whether that be a rendered, texture painted or a cladded exterior. Set the joints on the fibre cement sides and paint over for a seamless, conventional finish.

The fire retardant, insulated core dramatically reduces heat transfer with an insulation value of up to RT2.6, not including external cladding. Wiring services can also be run through the core ducts of the panel (in accordance with AS3959  for bushfire prone areas).

VerSIPanel can be installed almost anywhere and suit any footprint you require. Construction time is significantly reduced as minimal framing is required, making it a convenient and cost effective option for complete basic homes, home extensions, granny flats and holiday cabins.
