Product Description

MAXRaft Plus+ is designed to meet the requirements of the upcoming building code changes where embedded underfloor heating is specified and the slab is being built on less stable ground such as TC2, expansive soils, 200KPA or piled sites.

Typically the slab is either 320/340 or 400/420mm in height, however this can be adjusted to meet site specific requirements. 

The perimeter insulation, ribs and load bearing insulation from a standard MAXRaft® remain the same, however the SOLID PODS in the slab have increased thermal performance over traditional waffle pods to increase the R-value of the slab.

Each of these components combine to give a foundation with an R value between 2.5 and 4.03 depending on the design. 

MAXRaft Plus+ meets the requirements of Homestar V5 and can be adjusted to meet the requirements of Passive House Certification if required.
