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.

Dupont FROTH-PAK™ Foam Insulation is a two-component professional insulation kit. FROTH-PAK comes as a professional sealant for air sealing gaps and penetrations up to 4 inches wide or as a spray foam insulation to fill larger cavities providing both insulation and air sealing properties. The Class-A rating (flame spread of 25 or less) of FROTH-PAK™ Foam Insulation allows its use in a wide range of interior and exterior industrial, commercial, institutional and residential settings.

Dupont Styrofoam Brand Foundation Insulation products are installed against the exterior side of the foundation wall, suitable for use in pervious, semi-pervious & practically impervious soils and for sealing sill plates around door and window framing to reduce air infiltration.

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.

Knauf JET STREAM™ Fiber Glass Blowing Insulation is typically installed in open attics of both new and existing structures. It can also be used in retrofit closed-cavity applications such as exterior sidewalls or floored attics. Loose-fill blowing insulation is intended for use where pneumatically installed insulation is most cost-effective.

Knauf duct insulation is designed for commercial and residential air handling installations for cooling, heating, or dual-temperature service where good temperature control, noise absorption, and abuse resistance are required.

Available as board, liner, wrap and rigid plenum liner.

Knauf insulation board is a versatile product for thermal and acoustical applications such as: heating and air-conditioning ducts, power and process equipment, boiler and stack installations, metal and masonry walls, wall and roof panel systems, curtain wall assemblies, and cavity walls.

Available plain, with a factory-applied FSK facing or PSK (metalized polypropylene-scrim-kraft) facing, or with a factory-applied all-service jacket (ASJ).

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.
