How It Works
Heat loss through the concrete slab might not be as severe as heat loss through the ceiing. However, for homeowners looking to maximize the energy efficiency of their homes, insulated subflooring will go a long way in improving the home's overall thermal performance.

​The image above illustrates the separation between the underfloor heating and the concrete slab when applying the Amourcore floor system. This barrier allows for significant cost savings in heating, as most of the heat rises rather than being absorbed by the slab, resulting in reduced energy consumption for heating tiles and bathroom areas.
The image above illustrates the functionality of the Armourcore insulated floor system in conjunction with an advanced insulated wall. This design minimizes the areas where heat can escape. In a traditional insulated home, heating a room causes heat to reflect off walls and ceiling, but when it reaches the floor heat loss occurs. With proper insulation the image below shows how heat circulates when all four surfaces are insulated for maximizing energy efficiency.

​High Comprehensive Strength
OSB 3– or Oriented Strand Board – is strong, high density, versatile, reconstituted wood panels. It is identified by its characteristic wood strand surface and is composed of layers of engineered wood strands bonded with heat-cured adhesives.
Each layer is orientated at right angles to the adjacent layer creating a strong, stable panel that resists delamination and warping with a surface ready for any floor coverings.
