What is the InSoFast X-Bracket?

The X-Bracket is a pre-engineered support system designed to eliminate thermal bridging in blown-in and spray foam applications — all without the need for structural screws. It enables a truly continuous insulation system, unlike anything else on the market. With built-in structural support, it removes the need for custom, job-specific engineering.

How It’s Used & Key Benefits

Simple Installation: Easily installs with a nail gun or construction adhesive — no structural screws required.
Versatile Insulation: Works seamlessly with spray foam or any blown-in insulation.
Complete Rain Screen: Provides a ventilated rain screen from foundation to roof peak.
Universal Cladding Compatibility: Compatible with nearly all types of cladding.
Healthier, More Comfortable Spaces: Creates a healthier and more comfortable indoor environment by enhancing insulation performance.

The X-Bracket has nationwide code approval in the United States and Canada for interior and exterior use on various substrates. Wind loading data for wind speeds exceeding 300 miles per hour is included in the code report. There is no need for job specific engineering or complex details!
