Energy Efficient Home

Whether you’re building a new home or planning to reside or remodel your existing home, you have a lot of important decisions to make, especially when it comes to maximizing energy efficiency.  Using DuPont Weatherization System products to seal the building envelope could be the easiest, simplest step you can take to create a more comfortable, energy-efficient home.  

These innovative products can help your home meet the requirements for multiple Energy Star® programs [.pdf] and the National Green Building Standard™.   They may also help contribute toward U.S. Green Building Council LEED® (Leadership in Energy and Environmental Design) for Homes points and may add up to tax credits.

How it Works

By sealing the building envelope, DuPont Weatherization System products help to reduce nasty drafts and control air leakage, which helps to maintain the installed R-values of insulation [.pdf].  This helps heating and air conditioning systems to run more efficiently, saving energy and lowering your utility bills -- while keeping you more comfortable year round.

Sealing the building envelope also helps protect your home against bulk water intrusion and air-transported moisture, two factors that can dramatically reduce the effectiveness of your insulation and also lead to mold and mildew – and even wood damage -- as the water accumulates in your wall system. 

Trusted by Builders and Homeowners for Decades

For more than 25 years, DuPont Weatherization products have played an important role in making homes energy efficient.  They have been used on millions of homes in every climate and for every building façade to provide one of the best combinations of water, moisture and air infiltration protection of any secondary weather membrane.  As a result, homeowners around the world are enjoying greater comfort and superior energy efficiency.
