Prevent Heat Loss with MAXRaft Insulated Floor Slabs

With an approximate R-value of 4.5, MAXRaft enables homeowners to use the concrete slab as a battery for their home, anywhere in New Zealand. 

MAXRaft slabs prevent the 15% of heat loss in a home’s foundation and are approximately only 10% more expensive than a traditional waffle slab. With its patented edge profile, MAXRaft slabs also prevent 80% of heat lost through the edge of the foundation. Being fully insulated they are a great match when used in conjunction with underfloor heating.

MAXRaft is a premier concrete slab option that is both BRANZ appraised and CodeMark certified to give architects peace of mind. MAXRaft has a range of systems available on sites classified as good ground, TC2, piles and expansive soils. There is also a mid-floor system, MAXSpan.

Easy to specify, MAXRaft details can be found via their website or on any of NZ’s top architectural specification websites. Engineering design can be completed by MAXRaft or by any NZ chartered structural engineer. With installers available throughout the country, designers can opt for the supply of materials only or a full Installation.

With a focus on sustainability right through their process, all polystyrene components contain 15% recycled material and are delivered to site in pre-cut segments. A panel plan is provided making the onsite installation easy. Following installation, any waste is picked up, recycled and made back into insulating material.

The thermal envelope is critical to the performance of a home. To design warm, healthy and cost-effective living environments, Maxraft recommends starting with the right foundation.
