R-11* Polyurethane Insulation
Limited Lifetime Warranty
• The R-11* polyurethane insulation is substantially more effective than the same thickness of common polystyrene.
• Bulb-shaped bottom seal remains flexible even in the cold to keep out bad weather.
• The foamed-in-place insulation helps block street noise from entering into living areas that adjoin the garage.
