Not only the windows, but the doors, the attic, thru plugs and receptacles, basements or  crawlspaces….

Our homes provide shelter for the sun, rain, wind and snow, and they keep us warm and comfortable.  The floor, walls, roof, windows and doors all help to do this.  This ‘envelope’ separates our warm and comfortable indoors from the weather outside.  To maintain our comfort indoors, this envelope must function properly. 

Older homes can have gaps in the building envelope causing them to be too cold (in winter) or too hot (in summer) and cost the homeowner thousands of dollars to try an maintain some level of comfort.

A KMS House as a System check-up can determine how much energy your home is leaking.
