In many “pre-war” homes, exterior sidewalls were often left uninsulated, plaster on the inside and sheathing and siding on the outside used in its place. These walls allow the transfer of large amounts of heat, making the home inefficient, drafty, and uncomfortable.
Insulation can be added to exterior walls by “dense-packing” cellulose insulation into wall cavities from the exterior. This is accomplished by:
Removing a few rows of siding (above and below “window level” on each floor);
Drilling through the exterior wall sheathing;
Inserting a fill tube into the empty cavity.
Working from the top down, cellulose insulation is packed in at high density, resulting in a finished R-Value of 12-14, which drastically reduces drafts and leakage. When the work is completed, siding is replaced and sealed.
Foam Board for Sidewalls
In some homes, exterior walls contain only “half-batts” of insulation, or are packed with inferior products like newspaper, back-plaster, or balsam wool (sawdust). These low R-Value obstructions make dense-packing impractical, but there is still hope! In conjunction with a siding contractor, our team will:
Remove the original siding;
Tack a continuous layer of foam board insulation on to the exterior;
Seal seams, edges, window, and door openings;
Install new siding over this insulation layer.
Taking care to make sure sidewalls are properly insulated a sealed improves the comfort and efficiency (and curb appeal!) of your home.

I hired St. Croix Energy Solutions to complete insulation work on my newly purchased home that was built in 1873. After an energy audit, I had a number of companies come out to make bids and St. Croix Energy Solutions did a very thorough inspection - the only individual who went into the attic. The work was completed in less than a month (from the estimate), and was done quickly and efficiently in one morning. I have already noticed that the house has stayed cool on some of these very warm 80 degree days. I highly recommend St. Croix Energy Solutions.
