Casco Bay Insulation has been insulating homes in Greater Portland and along the Maine Coast since 2010. 


As your project partner, we take the time to understand your new or existing home project and its unique energy challenges.  We use sustainable dense pack cellulose insulation and vapor variable interior air barriers to create tight, moisture safe building envelopes.


From early in the design process to the final blower door test, we are committed to helping builders and homeowners meet today's challenging energy efficiency goals.
