FOAMGLAS® PERINSUL HL

Reducing Thermal Bridging in Load Bearing Conditions

Reducing Thermal Bridging in Load Bearing Conditions

As insulation values of new buildings improve, the need to limit heat loss through thermal bridging becomes increasingly important. Incorrect detailing at design stage or poor construction work can have a significant adverse effect on building performance. The insulation envelope of any heated building should be designed and constructed to limit heat loss through thermal bridging.

To stop thermal bridging, use load bearing FOAMGLAS® PERINSUL HL – The ideal solution.


FOAMGLAS® PERINSUL HL – the insulation that thinks it’s a brick!

Thermal Bridging

At structural junctions, where walls, door thresholds and timber frame meet the building structure, there is a significant structural thermal bridge. To help eliminate thermal bridges, the horizontal and vertical insulation layers should meet, however in this unique location, the insulation will be subjected to significant compressive loads. FOAMGLAS® cellular glass insulation easily supports uniformly distributed compressive loads without moving or flexing.

Thermal Bridging

FOAMGLAS® PERINSUL HL is positioned beneath the structural load, linking the horizontal and vertical insulation layers, thus eliminating the thermal bridge.

Advantages of the FOAMGLAS® system

Quality: Uniform thermal performance and load-bearing capacity (without additional support elements).

Cost efficiency: Efficient and well-priced solution for maximum thermal protection at minimal energy costs.

Sustainability: Optimum insulation and protection against moisture for generations.

Safety: The elements can easily be cut, assembled or used as smaller parts, without structural loss. There is no risk of damage from torch-applied bituminous waterproofing layers and contact with hot bitumen.

Functionality: Insulation and load-bearing element in one single functional layer. Prevents thermal bridges at the wall base. The insulation element can be combined with all commonly used type and size of bricks or timber frame.
