Increase Energy Efficiency with Insulation

Insulation is one of the most important factors in the comfort and energy efficiency of any building. By air sleaing your home, adding insulation or replacing old windows with Energy Star rated windows, you create a thermal envelope that encloses heated or cooled living spaces. This not only maintains comfort, it also saves energy, and helps lower your energy bills.

To increase the energy efficiency of your home, you should insulate all exterior walls that separate conditioned spaces from unconditioned spaces, including areas like knee walls that open to attics or garages. Insulating attics closes the thermal envelope from above. To make a more "secure" envelope, make sure you fill all cracks or openings with insulation. To control heat leakage, apply caulk or foam sealants around openings like window and door frames and any openings where wires or pipes go through the envelope.

Johns Manville's Formaldehyde-free™ fiber glass insulation products offer outstanding thermal efficiency and are Energy Star rated.
