Reducing heat flow within a building’s thermal envelope reduces energy consumption as well as potential condensation issues. Armatherm™ 500 thermal break material (TIM) significantly reduces energy lost from thermal bridging in building envelope connections. Armatherm™ 500 structural thermal break material is a high strength, thermoset polyurethane manufactured in several densities. Armatherm™ 500 is able to transfer a wide range of structural loads with a range from 0.14...

Armatherm™ FRR structural thermal break material provides a combination of low thermal conductivity and high compressive strength and has been used in thousands of structural steel framing connections, transferring load in moment and shear conditions. Armatherm™ FRR thermal break material can support up 310 N/mm2 and has an R value of 0.9 per 25mm. The material is made of a reinforced, thermoset resin which is fire resistant and has very limited creep under load, making it the ideal m...

In addition to the heat flow normally transmitted through the building envelope due to air leakage for example, multi directional heat flows are created by thermal bridges. Due to these three dimensional heat flow paths, it is difficult to use traditional area weighted averaging to obtain the accurate effects of a thermal bridge. The heat loss contribution of thermal bridging on expected building envelope performance is calculated most accurately using thermal modelling. Moreover, whole building...

Balcony Canopy Thermal Bridging Solution Balcony Thermal Bridging Solution The most common interface details for structural framing are canopies and balconies that use cantilevered steel or aluminium elements. These elements are typically connected to slab edges or spandrel beams on the interior side of the thermal envelope passing through insulation and air barrier layers. The R value of a wall assembly can be reduced by as much as 60% due to thermal bridging at balcony and canopy connections....

Continuous insulation is almost always compromised by metallic structural connections such as clips and girts which create thermal bridging when connected to steel stud framing. These connections in conjunction with the steel studs have a significant impact on the U value of wall assemblies. Insulation effectiveness can be reduced by as much as 50% due to these heat flow paths. Armatherm™ Z GIRTs improve the U value of cladding and wall panel assemblies by eliminating the use of highly con...

Internal steel columns traditionally extend through the building envelope floor slab and insulation at their base. In low temperature buildings such as freezer rooms and cold storage facilities, this creates a thermal bridge and point transmittance (heat loss) at the steel column base. This is also the case for exterior columns which support floors or roof overhangs. The column to roof connection interrupts the continuous insulation creating heat loss due to thermal bridging. Armatherm&tra...

Thermal Bridging at foundation wall transitions creates heat loss at the foundation perimeter. This reduces the exterior wall’s effective R Value. Foundations are part of a buildings’ thermal envelope. The intersection at a slab on grade to foundation wall and exterior wall to foundation transition are both areas where heat flows out of a building. This is due primarily to non-continuous insulation details. The linear transmittance (heat loss) at the base of the foundatio...

Masonry veneer walls require tie-backs and shelf angles which form significant thermal bridges and can reduce a walls’ R value by as much as 50% making it difficult to meet energy codes. Shelf angles transfer the masonry load back to the buildings’ structural steel or concrete slab edge interrupting the continuous insulation of the wall assembly creating a linear thermal bridge. To improve the U value of a masonry wall assembly, the shelf angle can be connected to the structure at disc...

Parapet Roof Penetration Thermal Bridging Solution The roof is part of the building envelope where penetrations such as davits, anchors and supports for dunnage extend through the thermal envelope and roof insulation creating non-continuous insulation. These interface details are typically connected to interior trusses or structural elements creating a thermal bridge and point transmittance (heat flow). The R value of the roof can be reduced by up to 40% in these areas. Parapet Roof...
