up to the elements for years on end. Built to meet these challenges — and look good
doing it — C.H.I. garage doors give you a wide range of options that fit your home's
individuality and help you maintain your investment in it. Call 911 Garage Door
Service, LLC for Quality and Professional Installation of your new C.H.I. door
Should I Consider an Insulated Door?
Insulated doors use either polystyrene or polyurethane. Polyurethane insulation
delivers twice the thermal performance of polysterene insulation of the same thickness.
It also adds strength and rigidity to the door panels and helps dampen sound transmission.
Polystyrene insulation uses rigid panels placed inside the door sections in the manufacturing
process. The polyurethane foam chemically bonds to the steel section and creates a composite
structure with greater strength, improved dent-resistance, and better thermal protection. The
same properties that help reduce the loss of energy, also give polyurethane insulation excellent
acoustic properties. An insulated garage door can significantly reduce the intrusion of street
noise into the home – especially when there are bedrooms or other living areas above or adjacent
to the garage
