14th October 2010 With recent focus on Insulation, Insulation, Insulation.... The Cornerstone Building systems R values for Polystyrene Structural Insulated panel is definitely top of the pack.
The 200mm thick wall having an R value of 4.3 & the 250mm wall at 5.75deg c/m3, without the Gibraltar board or cladding materials which will give additional benefit.
As existing New Zealand homes are being up upgraded, with underfloor and ceiling insulation, finally now focus is not only on the windows but the walls which make up 70% of the walls.
With this in mind it makes sense for those building their new homes or adding an extension, that they would consider the construction methods used for the structure carefully.
