Dupont Rigid Foam Insulation replaces non-insulating above-grade sheathing products like plywood, fiberboard and OSB, and eliminates the need for additional air barriers such as housewrap. It has clear film facings on both sides for added durability.

Styrofoam Boards are also designed for insulating interior basement walls, crawl spaces, and ceilings in both renovation and retrofit situations with precut insulation sheets and slotted edges that accommodate wood nailing strips that serve as a nailing base for drywall.

Kingspan GreenGuard XPS Insulation Board does not absorb water, is not a food source for mold, and is not subject to moisture-related damage and deterioration. An R-Value of 5.0 per inch of thickness makes it an excellent thermal insulator that increases the energy efficiency of your structures. And it retains its insulating properties over time. The board also provides an extra barrier against moisture infiltration. Choose between a square edge (CM) and an interlocking shiplap edge (SL) that helps reduce energy-robbing air leaks at seams and gaps.

XPS Insulation Board is ideal for a variety of applications, including below slab, below grade along the foundation, inside basement walls, exterior insulation over wood sheathing, and residing.

From its inception, Thermafiber, Inc. (an Owens Corning company), has been dedicated to improving life safety and fire protection by manufacturing mineral wool insulation for commercial, residential and industrial applications. Today, Thermafiber mineral wool resists fire and temperatures in excess of 2,000˚ F while also providing sound control and energy conservation. Applications of mineral wool include:

• Interior and exterior walls
• Pipes, ducts, cables
• Furnaces and kilns
• Sound enclosures
• Acoustical ceiling tile
• Asphalt mixes
• Brake shoes
• Office furniture
• Cements and coatings

For installation convenience and exceptional, long-term performance, the all-in-one ZIP System® R-Sheathing panel provides a new approach to sealing and insulating the building envelope. One panel delivers thermal, air and moisture resistance, while providing excellent strength and durability.
