X-Pin™ Insulation System for Composite Concrete Sandwich Panels
ICC-evaluated fiberglass pin connection for precast and tilt-up manufacturers. ESR-5267 certified.
X-Pin™ System Overview
Watch how the X-Pin insulation connector system is installed in precast concrete sandwich panel production.
A Major Milestone for the Precast Industry
The publication of ICC Report ESR-5267 marks a significant step forward in the broad market adoption of the X-Pin™ system. The X-Pin is now fully compliant with the updated ICC Approved Criteria AC 422, which governs fiber reinforced connectors for concrete sandwich panels.
This means the X-Pin can be confidently specified on projects with the most stringent building official requirements. Following rigorous ICC testing, performance parameters have been upgraded, eliminating performance-specific insulation requirements and simplifying specification.

Sustainability, Efficiency & Profitability
ICC Report ESR-5267 published, meeting Approved Criteria AC 422 for fiber reinforced connectors.
Suitable for use on projects with strict building official requirements.
Eliminates insulation-specific performance requirements after rigorous ICC testing.
Pre-routing of rigid insulation at facilities near your production plant reduces freight costs.
Significantly reduces material waste compared to traditional connection systems.
Faster bed turnover through simpler insulation placement and panel assembly.
Logistical and material savings that improve profitability on every job.
Available with labeled, trimmed insulation panels ready for production use.
Promoting Sustainable Building Practices in Precast
The X-Pin system promotes sustainable building practices by addressing two key areas of waste in precast panel production:
- Pre-routing near your facility. Insulation is routed close to your production plant, reducing transportation emissions and ensuring efficient, just-in-time delivery.
- Waste reduction. Unlike traditional connection systems that require field trimming and generate scrap, the X-Pin system delivers insulation pre-cut to specification, contributing to more responsible production practices.
