MAXRaft offer a range of fully insulated and thermally broken concrete slabs with R-values that easily meet the requirements of the building code.   

The team at MAXRaft is passionate about creating healthier, warmer and more energy-efficient homes. Historically New Zealander's have concentrated on insulating ceilings and walls, however, up to a third of a building’s heat can be lost through an uninsulated floor. Up to 80% of heat loss can be through the external edges of the slab. 

MAXRaft products combine strength with durability. The slab encases the perimeter and puts a continuous layer of MAXRaft between the ground and concrete, unlike traditional waffle slabs. This insulation has a dramatic effect on the surface temperature, significantly increasing the comfort of the home and the health of the family, all the while lowering the cost of heating. Iso-thermal analysis conducted in line with ISO 10211 comparing MAXRaft to a traditional waffle slab showed MAXRaft is significantly warmer, providing comfortable warmth even in the middle of winter climates. 

Fully engineered, MAXRaft has solutions for most types of ground (incl TC1/2/Exp. soils, piles), residential (single storey, multi-level or simply an extension) and commercial build while providing construction R-values between 2.5 and 5 depending on the project. Installation is quick, practical and efficient with site-specific insulated slabs delivered to the site in pre-cut segments. Founded in Queenstown, with representatives and install teams throughout New Zealand, MAXRaft is committed to providing well-insulated homes for its customers.

When considering Homestar or Passive House certification a MAXRaft slab is the perfect place to start.
