Air that leaks through your building's envelope − the outer walls, windows, doors, and other openings − wastes a lot of energy and increases your utility costs. A well-sealed envelope, coupled with the right amount of insulation, can make a real difference on your utility bills. Adding insulation has multiple benefits in commercial buildings - from increased energy savings, temperature and condensation control to noise reduction and environmental sustainability.

What can you do about it?

Add duct insulation.

To maintain consistent temperature throughout the building, duct insulation products help a building’s HVAC system deliver conditioned air at design temperatures without over-working the HVAC system. Properly insulated ducts also contribute to reduced operating costs.

Add insulation to ceiling and roof systems.

Proper ceiling and roof insulation can improve energy efficiency, lower cooling costs and provides greater comfort.

What is an R-Value?

Insulation is measured in R-values—the higher the R-value, the better your walls and roof will resist the transfer of heat. The DOE recommends ranges of R-values based on local heating and cooling costs, as well as climate conditions in different areas of the country.
