Description
Ultralight™ is a specialized composite board designed for floor heating applications. Manufactured as flat, flexible, sheets they are water and mold resistant. The top surface incorporates a heat-spreading aluminum layer combined with non-woven fleece.
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 and comfortable heated floor.
The base layer of non-woven fleece functions as a high-performance anti-fracture membrane for tile and stone floor coverings. It also facilitates a high-strength mechanical bond.
Features & Benefits
The heat spreading aluminum layer improves comfort and reduces running costs. This enabled the floor to achieve the same comfort temperature with 12% less energy.
• PEF insulation layer reduces heat up times by 76 minutes on slabs and reduces energy used during heat up by 69%
• Decoupling fleece layer provides high performance protection against tiles cracking due to lateral subfloor movement in accordance with ANSI A118.12 standard
• Warmup Ultralight is tested and rated for its acoustic performance by Intertek Building & Construction in accordance with ISO 10140-2, ISO 10140-3, ASTM E90 and ASTM E492 . Results obtained are tested values and were obtained by using the designated test methods in test chambers that satisfy the lab requirements specified in ISO 10140-5. See page 4 for detailed information
• Ultralight weighs just over 2lbs per board making it much lighter and easier to carry than standard cement-based tile insulation and backer boards and is more durable due to the high strength composite design meaning it wont break if bent or 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 ATSM-C627 (Robinson Test)
• The lightweight composite design makes it easier to cut curves and complex shapes, compared with cement-based tile insulation and backer boards and will not dull knife blades
• Ultralight will not crumble, dent, or create dust when cutting or kneeling on the boards which means no dust to clean or breathe in during installation
