Fiber Glass Insulation

Thermal Performance

Fiber glass 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 insulation power. CertainTeed fiber glass 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 recommended minimum.

FOR WALLS:
• Kraft facing serves as a vapor retarder
​• the side of the batt with the Kraft facing should be positioned toward the home interior
​• use rolls for large spans, use batts for small spans

FOR FLOORS & CEILINGS
• Use over unfinished areas 
• Kraft facing serves as a vapor retarder 
• The side of the batt with the Kraft facing should be positioned toward the home interior 
• Foil faced products have durable, resilient surfaces that provide greater water vapor resistance
FOR WALLS:
• Helps muffle sound in interior walls 
• May be combined with vapor retarder and used in exterior walls 
• Use rolls for large spans 
• Use batts for small spans
FOR FLOORS & CEILINGS
• Helps muffle sound between finished spaces.
