STEP Joists™ under floor radiant heating element is designed to provide radiant heat to existing floors by accessing the floor joists from below. This element can be ordered without slots and can be stapled or nailed through for easy installation.
The retrofit solution can be used as primary or supplementary heating and can be installed to heat under most floor coverings, including tile, stone, wood, laminate and carpet. For total heating a heat loss calculation is required.
After stapling the radiant heating elements between the floor joists and making the electrical connections, insulation is installed underneath the heating element. The insulation enhances the energy efficiency by minimizing heat loss and directing the warmth upwards through the floor.
STEP Joists™ is also available in 9" (22.9cm) width.
