Scope of use

Perimeter Insulation: Designed to both create a thermal break and bear the weight of your perimeter walls, these footings reduce heat loss from your floor at the point where up to 80% of such loss occurs.

Load Bearing Thickenings: Our load bearing thickenings can support load bearing walls within your home while maintaining a complete thermal envelope around your foundation. 

MAXSlab® Infill: Our infill is a cost effective method of ensuring that your home is properly insulated and a thermal break is maintained throughout. Standard infill is 200mm however this is sometimes adjusted to suit design requirements.

Features
  • Insulated throughout the underneath and perimeter of the slab.
  • Increased thermal efficiency
  • Quick and simple installation
  • Site-specific engineering
  • Reliable, proven construction details
  • Achieves R Values between R2.77 and R5.25. 

Engineering (PS1) for consent can be arranged by contacting MAXRaft®, we work with a group of engineers who are experienced in designing our foundations or alternatively contact us with any queries if you wish to design the MAXSlab.

Designs - Each MAXSlab® insulated foundation is engineered on a site-specific basis.

Performance

Each of these components combine to give high R values that easily surpass the building code..

Delivered to site in pre-cut segments along with a site-specific panel plan, our MAXSlab® insulation system is extremely efficient to install. 

Once the MAXSlab insulation is installed, simply place and tie the reinforcing, complete any required inspections and lay concrete.

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.
