Description

Marmox insulation boards are thin sheet boards designed to insulate the floor surface of new or existing buildings, saving up to 50% of the heat lost with conventional underfloor heating. This will significantly improve heat-up time and greatly reduce running costs. When used over the wooden floor, Marmox also acts as a tile backer and will not absorb moisture when used in bathrooms or wet areas.

This insulated tile backer board is made of extruded polystyrene, reinforced, and covered on both sides with a fibreglass mesh embedded into a thin cement polymer mortar. The individual board is 1250mm long X 600mm wide with an optional thickness of 6mm or 10mm. It is installed using a flexible tile adhesive in a similar manner to a large tile.
