    100mm Xtratherm Thin-R Hyfloor XT-HYF PIR Insulation For Floors (Pack-4)

    The floor in any building is an area of considerable downward heat loss when not properly insulated. Xtratherm has developed Thin-R Hyfloor XT/HYF (T&G) engineered tongue and grooved floor insulation as the answer to achieve lower U-values – in a practical and robust manner.

    Xtratherm XT/HYF has a superior thickness to performance ratio, allowing the lower targets required under Building Regulations to be achieved with minimum thickness.

    Key Points

    - Robust Tongue & Groove Jointing

    - High Compressive Strength

    - Suitable for Underfloor Heating

    - Perimeter Strips for Robust Detailing

    - Reduced Insulation Thickness

    - Excellent 0.021 W/mK Lambda value


    - The XT/HYF (T&G) tongue and groove jointing offers a practical on-site solution that results in a more robust continuous layer of insulation, minimising the threat of thermal bridging.

    - XT/HYF (T&G) is lightweight and suitable for use with underfloor heating. Thanks to its thickness to performance ratio, XT/HYF (T&G) allows for reduced insulation thickness.

    Handling, Cutting and Storage

    - 100mm Xtratherm insulation should be stored off the ground, on a clean flat surface and must be stored under cover. The polythene wrapping is not considered adequate protection for outside exposure. Care should be taken to protect the insulation in storage and during the build process.

    - The insulation boards can be readily cut using a sharp knife or fine toothed saw. Ensure tight fitting of the insulation boards to achieve continuity of insulation as asked for within the ACDs. 

    - HYF  provides the most efficient means of floor insulation. It has the strength and thermal properties required to reach the high performance U-Values asked for in the Building Regulations.

    - Good detailing at the wall/floor junction is essential to reduce thermal bridging. By placing an upstand of Xtratherm Perimeter strip (XT/STR) insulation 25mm thick around the external and internal wall/floor junctions, a robust detail is created.

    To achieve good detailing, Construction Details (ACDs) should be followed during the planning, design and build process.


    Xtratherm products are stable, rot proof and will remain effective for the life span of the building, dependent on specification and installation. Care should be taken to avoid contact with acids, petrol, alkalis and mineral oil, when contact is made, clean materials in a safe manner before installation.
