Next generation performance

The ISO Clip is a thermal barrier separating the interior of the building from the exterior framing components. Unique design features reduce the thermal transfer from the interior to the exterior. Thermal performance of the clip has been verified by the industry leaders, Morrison Hershfield.

The ISO Clip is engineered to perform on all substrates; including concrete, concrete block, steel studs or wood. One ISO Clip can accommodate a variety of insulation thicknesses or wall depths, eliminating the need for shims or multiple clip sizes. The ISO Clip is designed to accept either vertical or horizontal sub-girts. Versatility and ease of use combined with the effective use of insulation makes the ISO Clip the product to specify.

The ISO Clip team is available to assist you with all stages of your building performance design. Full sets of typical construction details, engineering load tables and calculations are available. Your engineers or ours, are able to design the most functional wall assembly for your chosen insulation and façade cladding.

Morrison Hershfield report

The ISO Clip provides a thermally broken and intermittent structural attachment for cladding systems to exterior wall assemblies. The clip is fabricated from Z-275 galvanized steel, and over-molded with a plastic isolator. Both horizontal and vertical steel girts can be attached to the ISO Clip, as shown below in Figures 1 & 2. The horizontal flange of the clip has a punched slot that allows the sub-girt to be adjusted and fastened to the clip. The plastic isolator between the metal clip and the wall provides a thermal break that reduces thermal bridging. For steel stud assemblies, the clips are fastened through the exterior sheathing directly to the steel studs using self-drilling screws.

For exterior insulated steel stud assemblies, the ISO Clip System provides an effective means of reducing thermal bridging in exterior façade systems compared to traditional continuous girt systems. The ISO Clip System can be used to meet many of the demanding thermal requirements from current energy codes and standards in Canada. The U- and R-values provided by this summary can be used for compliance calculations for any of the compliance paths set forth in ASHRAE 90.1, NECB or SB-10.thermal bridging. For steel stud assemblies, the clips are fastened through the exterior sheathing directly to the steel studs using self-drilling screws.
