Underfloor Heating Insulation

Competitive Trade Pricing with quantity discounts. Online supplier of Underfloor Heating Insulation Boards.

About

Floor heating insulation boards are used to insulate the subfloor when installing underfloor heating systems. These boards are typically made of a rigid foam material and are placed over the subfloor before the underfloor heating pipes or cables are installed. The insulation boards help to keep the heat generated by the underfloor heating system from being lost through the subfloor, which can improve the overall efficiency of the system.

There are different types of insulation boards that can be used for underfloor heating, including polystyrene, polyurethane, tile backer and extruded polystyrene. Each type has its own unique properties, such as thermal conductivity, compressive strength, and moisture resistance, which can affect the performance of the underfloor heating system.
