Insulation System for Flat Roofs & Balconies

XtraVIP Insulation System for Flat Roofs & Balconies is a rigid Vacuum Insulation Panel (VIP), consisting of a compressed, fumed, silica sand, microporous core which is evacuated of air and moisture before being
encased and sealed in a special thin, gas-tight, hybrid aluminium foil envelope. Encapsulated and protected within a robust two component elastomeric polyurea waterproof coating.

XtraVIP

Xtratherm offers a cost effective solution for builders and specifiers for the closing of cavities around window and door openings, preventing cold bridging, damp penetration, air infiltration and condensation.

Hyfloor Tongue & Groove Insulation

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

Why choose Xtratherm Hyfloor Tongue & Groove Insulation?

  • 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.
  • It 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. The product should be laid staggered in a break bonded pattern and fitted tightly at edges and around any service penetrations.
  • XT/HYF (T&G) 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.

Hyfloor (T&G) has a superior thickness to performance ratio, allowing the lower targets required under Building Regulations to be achieved with minimum thickness.
