Warmup Ultralight Electric UFH Insulation Boards - Heat Spreading, Decoupling and Acoustic

The Warmup Ultralight Electric UFH Insulation Boards for Decoupling Systems are specialized 4-in-1 composite boards designed to enhance electric underfloor heating systems, providing insulation, heat spreading, decoupling, and acoustic benefits for tiled and other floor finishes.

Product Description

Warmup Ultralight Insulation Boards are engineered with a multi-layer construction for optimal performance in floor heating applications. Manufactured as flat, flexible sheets, they are water and mold resistant, lightweight, and easy to install. The boards feature a top non-woven fleece for direct adhesion of heating elements, an aluminum layer for even heat distribution, a PEF insulation core to reduce heat loss, and a bottom decoupling fleece to protect against subfloor movement. Ideal for use under electric UFH systems like DCM-PRO or Peel and Sticky UFH Mats, they significantly improve energy efficiency by reducing heat-up times by up to 78% (from 2.5 hours to 25-27 minutes) and saving up to 71% on energy costs. These boards also offer sound reduction comparable to dedicated acoustic products, making them suitable for residential and light commercial installations.

Key Features

• 4-in-1 functionality: Insulation, heat spreading, decoupling, and acoustic performance in one board.
• Lightweight design: Only 1.145 kg/m², easier to handle than cement-based boards; won't break if bent or dropped.
• Fast heat-up: Reduces ramp-up time by 78% and energy usage by 71%.
• Water and mold resistant: Durable for wet areas like bathrooms and kitchens.
• Even heat distribution: Aluminum layer ensures uniform warming.
• Decoupling protection: Guards tiled floors against cracks from subfloor movement.
• Acoustic benefits: Tested by Intertek, comparable to rubber, cork, or foam products.
