PLASTI-GRIP CBW Flat Insulation Washers are the ultimate fastening solution for securing rigid insulation and building wrap to a variety of substrates, including masonry, foundation walls, wood, and steel. Featuring a 1-3/4" diameter flat plastic washer, they deliver superior holding power while minimizing insulation facer damage with a flexible perimeter design.

Designed for energy efficiency and labor savings, these washers reduce thermal bridging and air infiltration, making them an ideal choice for foundation walls, basements, garages, crawl spaces, attics, and both interior and exterior walls and ceilings.

Compatible with screws, nails, and Tapcons, we recommend using SPAX #8 or #10 construction screws with a minimum 1/4" diameter head for optimal performance. Whether you're a contractor or DIYer, these washers make securing rigid foam insulation and mineral wool faster to install and more energy efficient.

Key Benefits:
* Fast, Secure Installation - No pre-assembly required, reducing labor time.
* Superior Holding Power - 1-3/4" tapered flat washer ensures a firm grip.
* Flexible Perimeter - Minimizes tearing of insulation facer.
* Energy Efficient - Reduces thermal bridging and air infiltration.
* Versatile Compatibility - Works with nails, screws, and Tapcons.
* Multi-Substrate Use - Ideal for wood, steel, masonry, and foundation walls.

Shoot it, screw it, or nail it-PLASTI-GRIP Flat Insulation Washers provide a durable, high-performance fastening solution for rigid insulation attachment in residential, commercial, and industrial applications.SPAX screws start as high-quality cold-rolled carbon steel wire, then undergo precise heat treatment to enhance strength and durability. This meticulous process, perfected over time, ensures every screw delivers superior performance in demanding applications. Unmatched Strength & Durability: Proudly crafted on American soil and made domestically in Bryan, OH with globally sourced materials.
