Airtight Insulation will perform an energy audit to assess the inefficiencies that exist in your home and to define potential corrective actions, we will sit down with you to review our findings, make recommendations, and estimate costs and savings.

Attic Insulation

Insulating your attic is one of the most efficient and effective ways to help you save both money and energy. Along with helping keep the heat in your living spaces, proper insulation in the attic can also help prevent ice dams.



Basement Insulation

As a homeowner, you want the thermal boundary to be consistent throughout your entire home. What that means is you want to have the same insulation value throughout. This starts with your basement, insulating everything above grade.

Winter is a time when heated air coming from heated rooms escapes to unheated spaces of your house, like your garage, basement, or outside. In summer, cooler air is replaced by warmer air, causing air conditioning systems to work harder.

Properly insulating key areas of the house, including the basement, will prevent heat flow, which will lessen the heating and cooling demands.

The various types of basement insulation are: sprayed foam insulation, Thermax, and cellulose insulation. One or all of these may be used to remediate any issues that might exist.

This decision depends on the recommendations of the energy audit in consultation with the homeowner.

Air Sealing

A “leaky” house causes higher energy bills and allows excess moisture and contaminants to enter the home.

Our goal is to eliminate gaps in the building envelope to reduces air leakage from the areas such as sill boxes in the basement, dropped soffits, interior and exterior wall plates, chimneys, light fixtures, and electrical penetration.

Air sealing a house increases your comfort by reducing the drafts in a house and by reducing the cycle time that your heating and cooling systems are going to run.




As you look at your home, you will notice that the sidewalls represent the largest area exposed to the outside air. Homes lose heat through their sidewalls. Measured in square footage, the sidewalls in most houses represent the largest exposure to the outdoors, so it makes sense to make them as resistant to heat flow as possible.

The decision concerning the best insulating material to use in the sidewalls will be determined in consultation with the home owner.
