The Importance of Air Sealing Attics Before Insulation - South Portland, ME - Rook Energy Solutions

When choosing to insulate an attic, one of the important questions to ask:  is insulation just being blown over the existing insulation, or is insulation removal and air sealing included in the estimate? With minimal air sealing, and adding insulation over existing material without air sealing first, homeowners will not got the results they desire and their retrofit can fall well short of being truly effective for the life of the improvement.

Home Improvement - Handyman: Window & Door Installation - Kitchen renovation - Attic Insulation - Shake Siding | Biddeford Pool, Maine | Rook Energy Solutions

This was a great Home Improvement project in Biddeford Pool, Maine. The home owner has a baby on the way and wanted to get many projects out of the way prior. The work scope included re-configuring the kitchin to install a door leading the porch by moving a kitchen sink and counter. We also transitioned an enclosed porch into a functional bedroom by installing insulation in the attic, enclosing a window and adding awning windows followed by shake work on the exterior of the house. Finally, we installed an exterior door into the basement for easier access for the home owner. A perfect Home Improvement job for Rook Energy Solutions.

This energy audit depicts classic cape and bungalow solutions dealing with knee wall, enclosed slope and attic flat insulation issues. 

In December we performed an energy audit on this small, very nice home that really needs some weatherization attention. Recently moved in less than one year ago, the homeowners had already experienced high heating costs, drafty and inconsistent heating, and bad ice damming issues. With the inefficiencies we found they will also no doubt experience hot temperatures in the 2nd floor bedrooms this summer - all stemming from insufficient R Value (amount of insulation) and air leakage leading to devalued insulation.

When air moves through fiberglass it strips it of its ability to hold heat. So when you vent an attic and introduce cold air into an attic space, you're effectively promoting the devalued performance of your fiberglass insulation.
