New from Warmup, Ultralight insulation is first of its kind offering insulating, heat-spreading, and decoupling benefits all in a one quarter inch thick board. Ultralight insulation boards are the first insulation boards designed specifically for use with electric underfloor heating. The 2’x4’ boards pair with the Warmup DCM-PRO Membrane floor heating system to deliver a savings of $1, per square foot, per year.

Ultralight is designed for the most efficient use of electric floor heating systems. The layers that make up Ultralight deliver 3 benefits in 1 board; insulating, heat-spreading, and decoupling.

The surface of Ultralight features a secure synthetic fabric layer as well as a heat spreading aluminum layer. The surface materials of the board promote even heat distribution to eliminate cold spots.

The core of PEF insulation provides thermal separation from the floor beneath, ensuring a rapid thermal response of a heated layer of tiles or leveling compound above. The rapid thermal response promoted by the PEF insulation and diffusion layer allows the flooring to heat up faster, resulting in a more energy-efficient heated floor.

The base layer of non-woven fleece functions as a high-performance anti-fracture membrane for tile and stone floor coverings in accordance with ANSI A118.12 standard. The base layer also facilitates a high-strength mechanical bond.

True to its name, Ultralight weighs in at just over 1lb per board making it much lighter and easier to move compared to standard cement-based backer boards. Ultralight cuts to size easily, straight or curved, without dulling a utility knife or creating any dust.

Despite it’s ease to cut and inability to dull a knife, Ultralight is durable and will not bend, break, or crumble even if it is dropped. Ultralight achieved Heavy Commercial rating when used with large format tiles (600 mm x 600 mm) and Light Commercial rating when used with standard tiles (300 mm x 300 mm), in accordance with ASTM-C627 (Robinson Test).
