Grand Rapids, MI 49503 Tel: 616-454-3100 Email: request info Web: https://www.trufastwalls.com [ Click Here ] for additional information. TRUFAST Walls was founded in 1993 and manufactures innovative fastening systems for the building envelope. TRUFAST Walls employees are industry leading experts, and operate multiple cavity stamping presses, and state of the art injection molding machines to keep up with ever increasing demand. Our primary focus is fasteners to attach rigid foam insulation, EIFS, lath attachment for stucco or stone veneer, building wrap attachment as well as other niche applications including tile backerboard and plaster repair. Recently implemented energy codes have changed the insulation requirements for virtually all new construction. With those changes, TRUFAST Walls has partnered with leading foam insulation, building wrap, and air/moisture barrier manufacturers and has developed fasteners and tools to rapidly install their material. Demonstration videos on our website showcase our various fasteners and tools. Please contact us for the distributor that serves your area or register your job for quick analysis of your fastener needs. We are proud to be "Made in America" and we thank you for your support.
