MAXRaft Insulated Flooring Brings Time Savings to Affordable Housing Projects

MAXRaft offers smart insulated flooring systems designed to bring long-term cost savings to Kiwi homes. Their innovative products have been specified on a range of affordable and social housing projects across New Zealand, including single and multi-unit developments. The choice to use MAXRaft brings improved comfort and excellent energy efficiency to housing, ensuring a healthy environment and lower power bills for occupants.

Options to meet budget, ground conditions and R-value requirements

For affordable housing projects, MAXRaft’s insulated flooring systems can be adapted to meet different R-value requirements and budget constraints. The systems are designed to exceed H1 requirements, with MAXRaft’s R-value calculator available to help you determine the most suitable solution for your project. With options for both TC1 and TC2 ground types, MAXRaft can be specified on a broad range of projects across New Zealand.

Prefabricated to save time on site

Prefabricated systems can offer big benefits for affordable housing projects by saving time on site and reducing labour costs. MAXRaft’s systems are prefabricated offsite to project requirements, making installation simple and reducing waste on site. From their patented MAXEdge L-shaped perimeter insulation to their pre-cut MAXSlab segments and MAXRaft pods, the system is designed to ensure optimal efficiency on site.

Long-term energy savings

MAXRaft’s insulated flooring systems provide excellent thermal performance by preventing heat loss at the slab edge. This increases the energy efficiency of homes, resulting in lower power bills for homeowners, a lower carbon footprint, and healthier homes.

BRANZ appraised for straight hold down fixings with 90mm framing

MAXRaft has recently upgraded their MAXEdge perimeter insulation system to allow for straight bolt fixing for 90mm framing commonly used on affordable housing projects. This BRANZ appraised solution further simplifies installation by allowing for fewer bolts at wider centres and faster fixing.
