Air Sealing and Insulating Your Home

As a homeowner, it is important you understand the basic points about sealing and insulating the shell or building envelope of your home. This weatherization strategy is always important and in some homes, can be as important as insulation itself.

Tests have shown over and over that insulation works best and the performance is most optimal when there has been none to start with. Adding more material to an already insulated space produces less dramatic results. In outer walls, ceiling, windows, doors, and floors air sealing is often the most cost effective way to improve every efficiency and comfort. Check out this link to see the DIY Air Seal Brochure by Energy Star®. This guide also includes information about adding more attic ventilation.

Maximizing the return on your weatherization investments means you should have a good understanding of your specific building and what can be done to improve its energy efficiency. Every building is different. This brochure is a good starting point to understanding how air sealing works with insulation and ventilation to complete your home's weatherization package.
