Gorilla Buck – ICF Window Bucks for Sturdy Openings
The Ultimate Insulated Window & Door Buck System for ICF Construction
Gorilla Buck products are designed to provide unmatched insulation and seamless installation, offering an ideal solution for ICF window and door buck systems.
Crafted from high-density expanded polystyrene (EPS) and 100% recycled plastics, Gorilla Buck’s innovative design effectively blocks air and water infiltration with a precision friction fit.

ICF-Compatible Design and Superior Insulation
Specifically engineered for use in ICF construction, Gorilla Buck is the go-to solution for eliminating thermal bridging in ICF openings. Tailored to fit nearly any ICF brand, the Gorilla Buck integrates with ICF wall forms, effectively mitigating air and water infiltration at crucial ICF wall connections.
This is achieved through the incorporation of friction-fit internal rails that securely fasten into the ICF wall forms and mechanical keyways that unite the foam and panels.
Multi-Functional Design for Enhanced Performance
Gorilla Buck sets itself apart with its multi-functional design, featuring polypropylene webs that serve as attachment elements for securing trims, windows, doors, and wall finishes.
Gorilla Buck can also accommodate concrete anchors and reinforcement brackets, providing a versatile and comprehensive solution for ICF construction projects. This innovative design ensures that Gorilla Buck simplifies installation processes and enhances the structural integrity of ICF window and door openings.

Benefits That Redefine ICF Construction
Gorilla Buck is engineered to deliver benefits that redefine ICF construction and insulation standards. The key advantages of Gorilla Buck include:
- Energy Efficiency: By creating an airtight structure, Gorilla Buck eliminates thermal bridging, reduces energy usage, and enhances sustainability.
- Stable R-Value: Maintaining a stable R-value over time, Gorilla Buck ensures consistent insulation performance without deterioration.
- Moisture Resistance: With its closed-cell polystyrene insulation, Gorilla Buck is proven to resist moisture gain, enhancing the durability and longevity of ICF constructions.
- User-Friendly Installation: Gorilla Buck’s design simplifies the installation process, eliminating the complexities associated with traditional wood buck frames and ultimately saving time and labor costs.
- Cost-Effectiveness: Gorilla Buck significantly reduces material and labor costs by eliminating the need for custom lumber cutting, making it a cost-effective choice for ICF construction projects.
