If you plan to use Styrofoam™ Brand Extruded Polystyrene from Dow Building Solutions to create a layer of continuous insulation you need to consider your options for permanent and energy efficient attachment… Rodenhouse Fastening Systems is here to support you!

Before attaching the continuous insulation you need to first attach the air and weather barrier over the exterior sheathing, such as the layer of DuPont™ Tyvek® as you see here. To attach the building wrap use the 2” dia. Thermal-Grip® flat washer with Grip-Deck® ci ceramic coated screws. The solid cap is designed to compress on the building wrap to help seal against air and water penetration. The Grip-Lok® auto-feed fastening system is a labor saving option to rapidly attach building wrap to steel or wood studs.

To attach rigid Styrofoam™ Brand Insulation to steel studs, wood studs, or masonry substrates we have various fastening options to consider.

Our 2 inch diameter Thermal-Grip® ci prong washer can be used with Grip-Deck® ceramic coated self-drilling screws to easily attach into all gauges of steel. The dual prong feature on the bottom of the washer enables pre-spotting on the surface of the insulation for easy "on-the-wall" screw assembly.

For major labor-savings, use our Grip-Lok® Autofeed Fastening System which is specifically designed to rapidly attach our screws and washers into steel studs. This system is up to 4 times faster than using traditional bulk screws and washers!

To attach continuous insulation to wood studs the 1 ¾’ dia. Plasti-Grip® ci prong washer is a great option that can either be used with Grip-Deck® screws, or it can be shot-in with ordinary pneumatic nail guns. The flexible design compresses on the surface of the insulation for a flush finish.

For masonry cavity wall applications, you can utilize the Pos-i-Tie® veneer anchoring system with our 2" diameter Thermal-Grip® brick tie washer to prevent insulation blow-off and also to prevent air and moisture penetration at the anchor points.

For adhered masonry such as stucco or stone veneer, use our Grip-Plate® lath and plaster washers with Grip-Deck® screws to attach lath outboard of the insulation. The Grip-Plate® lath and plaster washers are 1 ¼ inch in diameter and help spread the load to be able to support heavier cladding outboard of the insulation.

For attaching rigid Insulation to a concrete block or masonry substrate, utilize our Plasti-Grip® PMF Anchor. PMF stands for Plastic Masonry Fastener. These are easy to use by pre-drilling through the insulation and into the block or concrete substrate, placing the concrete anchor into the hole, and tapping it flush with a hammer. No adhesives, pins, or screws required.
