MAX85
Description

MAX85 is designed to meet the minimum requirements of the new H1 building code. Unlike MAXRaft's other products MAX85 does not have insulation in the thickenings and ribs. The patented insulated edge provides a complete thermal break around the perimeter of the slab with waffle PODS throughout the rest of the floor. 

Like all other MAXRaft slabs the polystyrene materials in MAX85 are delivered to site pre-cut to ensure maximum efficiency when installing and maximum sustainability in the factory.

MAX85 R-value ranges from 1.5 to 2.48 depending on the internal A/P ratio of the building.
