Who makes Thermax insulation?
Engineered for both concealed and exposed applications, DuPont™ Thermax™ Sheathing is an easy-to-use nonstructural rigid insulation board with a fiberglass-infused foam core that helps improve fire performance and dimensional stability.
What is Dow Thermax Sheathing?
Dow THERMAX Sheathing is a rigid foam insulation that effectively reduces condensation for exceptional moisture protection. Dow THERMAX Sheathing is specially designed to have a Class A fire rating and can be used in a range of concealed and exposed applications, above and below grade.
What is the R-value of Thermax insulation?
R-6.5
THERMAX™ Sheathing rigid insulation from Dow joins a core of glass-fiberreinforced polyisocyanurate foam with aluminum foil facers. The insulation delivers excellent thermal performance (R-6.5* at 1”) with good moisture resistance, reliable dimensional stability and exceptional fire performance.
What is the R-value of 1 2 Thermax?
[2] Thermax Brand insulation has a higher R-Value at lower temperatures. At 40°F mean temperature and 1” board thickness, R-Value is 6.6, and for 2” board thickness, R-Value is 13.2.
What kind of insulation is Thermax?
rigid foam board insulation
Designed for immediate insulation and weather protection on the job site, as well as long-term thermal performance, DuPont™ Thermax™ (ci) Exterior Insulation is a rigid foam board insulation with a glass-fiber-reinforced polyisocyanurate foam core that helps improve fire performance and dimensional stability.
How do you cut Thermax insulation?
There are two ways to cut Thermax™ Sheathing. One way is to use a straight edge and a utility knife, making sure to cut all the way through the facing. Make sure the surface backing is safe to cut on. Or, Thermax™ Sheathing may be cut with a small handsaw.
Is Polyiso fireproof?
Polyiso offers superior surface burning and flame spread fire-resistance properties in comparison to minimum building code requirements and other common combustible insulating and structural materials used for building envelope construction. Polyiso will not melt or drip when exposed to fire.
Is polyisocyanurate a foam plastic?
Polyisocyanurate foam plastic insulation, or polyiso for short, meets the most stringent building code requirements for use in buildings of any construction type and is one of the most regulated building products used in the construction of building envelopes.
Is polyisocyanurate foam flammable?
“Rigid polyurethane and polyisocyanurate foams will, when ignited, burn rapidly and produce intense heat, dense smoke and gases which are irritating, flammable and/or toxic. As with other organic [carbon based petrochemical] materials the most significant gas is usually carbon monoxide.
