Cascadia Clip® Fiberglass Thermal Spacers for exterior insulated cladding systems
Traditional methods of attaching cladding through exterior insulated wall assemblies cause so much thermal bridging that meeting code requirements is virtually impossible. The Cascadia Clip® is our answer to that problem. As one of the first thermal clip systems on the market, we are experts on thermal bridging and cladding attachment. Cascadia Clips are universal, and can be used with any type of cladding.
Our thermal spacer made from low-conductivity fiberglass material greatly reduces thermal bridging, improving the effective thermal resistance of the exterior wall. The Cascadia Clip makes ASHRAE 90.1 Or NECB 2011 compliance simple and cost-effective.
Cascadia Clips come in 8 sizes, offering you cladding attachment solutions for up to 8" of thermal-bridging-free exterior insulation.
2" | 2.5" | 3" | 3.5" | 4" | 5" | 6" | 8"
The Cascadia Clip is our solution to the issue of thermal bridging through exterior insulated wall assemblies, and is the best clip on the market for addressing all the issues most often associated with cladding attachment systems:
- Superior thermal performance
- High structural strength
- Safety in the event of fire
- Adjustability to deal with uneven wall substrates
For more information on any of the above considerations, please have a look around this page for details, drawings, test reports, and videos supporting all of the uses of Cascadia Clips.

- In the US, the Cascadia Clip has been approved for use in all types of construction under the IBC, as per our code compliance report. The report draws on a variety of fire-related testing, including a successful NFPA 285 test. Contact us for a copy of the NFPA 285 report or fire engineering reports, or for any further information on combustibility requirements.
- In Canada, the Cascadia Clip® has been approved for use in non-combustible wall assemblies as a "minor combustible component," in accordance with Article 188.8.131.52 of the Model National Building Code. This is confirmed by a ruling from the Building and Safety Standards Branch of the BC Ministry of Energy and Mines, in addition to analyses from code consultants or fire protection engineers in every major state and province.
