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.

Knauf's cost-effective thermal and acoustical batts and blankets are made from highly resilient, inorganic glass fibers bonded by a thermosetting resin.

The products are available unfaced or with kraft, foil, or flame-rated FSK-25 (Foil-Scrim-Kraft) foil facings.

Nu-Wool is a spray-in-place, energy-saving cellulose insulation. It eliminates the voids and air pockets common with other insulation materials. In fact, you may save as much as 40% on your heating and cooling bills by choosing Nu-Wool Insulation when you build.

Nu-Wool has a high R-value, offering superior thermal and air-filtration properties, defending against mold growth and even dramatically reducing noise transmission through floors and walls.

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.
