Choosing the correct insulation for your underfloor heating is essential to provide maximum efficiency. Without insulation, the warmth created from underfloor heating can be driven downwards into the sub-floor and lead to slower warm-up times. It’s highly recommended that all underfloor systems are insulated as it can increase its effectiveness considerably – in some cases by up to 10 times! Our range of underfloor heating insulation boards is compatible with a wide range of sub-floor types, floor coverings and heating systems to ensure easy installation and efficient performance.
