GreenGuard is the nation’s leading brand of siding underlayments. Made of extruded polystyrene (XPS), our underlayments provide superior moisture resistance and are perforated to allow moisture vapor to escape. They do not absorb water, are not a food source for mold, and are not subject to moisture-related damage and deterioration. They also retain their insulating properties over time. All of our underlayments are designed to lay flat, giving siding a smooth, even finish. Plus they are lightweight and durable, so they cut easily without crumbling.
An extruded polystyrene foam insulation board with square edges on all four sides. Special 16” width makes it easy to fit between brick ties in cavity wall applications. Cavitymate™ XPS Insulation is a Styrofoam™ Brand XPS solution that’s conveniently sized to fit between wall ties
Kingspan Kooltherm offers an extensive range of premium performance insulation products for wall, floor, soffit / structural ceiling and concrete sandwich wall system applications. It has a fiber–free rigid thermoset phenolic insulation core that resists both moisture and water vapor ingress, and exhibits excellent fire performance.
OPTIM-R vacuum insulated panels (often called a VIP) offer solutions for those times when you know you’re going to run out of space or for when space is tight.
Kingspan OPTIM-R is a next generation insulation comprising rigid vacuum insulation panels (VIP) with a microporous core, which is evacuated, encased and sealed in a thin, gas–tight envelope to give outstanding R–values and an ultra–thin insulation solution.
The high level of thermal efficiency, up to 5x better than other commonly available building insulation materials, with minimal thickness achieved by Kingspan OPTIM-R can provide solutions for applications where a lack of construction space or depth is an issue.
Tuff-R™ Polyisocyanurate Insulation consists of high-performance, high R-value, closed-cell polyisocyanurate foam core boards sandwiched between a choice of durable exterior foil facers. On Tuff-R™ Insulation, one facer is a continuous sheet of aluminum foil; the other is a Tri-Plex facer consisting of a three-ply laminate of durable kraft with aluminum foil on both sides. Tuff-R™ helps reduce air infiltration through the wall by covering cracks between the framing members and sealing tightly against the studs.
Made for new frame walls or retrofit of existing walls in residential construction, Tuff-R™ products feature a high-performance foam core sandwiched between durable exterior facers. Rigid and water resistant, Tuff-R™ works in both interior and exterior walls.
Thermax™ Sheathing* is a non-structural, rigid board insulation consisting of a glass-fiber-infused polyisocyanurate foam core laminated between 1.0 mil smooth, reflective aluminum facers on both sides. The glass-fiber reinforcement contributes to improved fire performance and dimensional stability. * Thermax™ Sheathing is a former product of The Dow Chemical Company
A non-structural rigid board material, Thermax™ Sheathing consists of a fiberglass-infused foam core that helps improve fire performance and dimensional stability.
Changes in the residential building code are driving home-builders to rethink their approach to improving Home Energy Rating System (HERS®) performance. Building science shows that improvements in lighting, appliances, mechanical equipment, glazing and air infiltration provide only limited gains at best and often at a high price.
