Fiberglass insulation delivers exceptional energy efficiency and thermal performance
that result in more comfortable living spaces and lower energy costs for homeowners.
Heat constantly moves to colder areas, which is why homes need thermal resistance
(measured by R-Value) between the indoors and outdoors. The higher the R-Value,
the greater the insulating power.
CertainTeed fiberglass insulation is compression packaged for ease of handling and
comes in a wide range of R-Values, sizes and facings. It’s critical to determine the
recommended R-Value according to your region. However, code is a
