If you own an older building or work on older buildings, you know just how many unexpected challenges you can encounter throughout a renovation process.  One common problem with homes and buildings built in the 1800's is their narrow walls. Insulating these homes presents a real challenge because there simply is not enough space for inches and inches of fiberglass insulation. Thankfully, there is a solution -- spray foam insulation. It's not just for building energy-efficient homes any more. It's also a great solution for increasing the energy efficiency of older homes.


The Story of an Old Home

Old, narrow walls were a problem in the Joseph Story House in Salem, MA. Recently, this building was purchased by new owners who wanted to make it more energy efficient. They soon discovered that there was only a mere 1 1/2 inches of space between the brick walls and the interior walls. The home was built long before the days when insulation was the norm, and so installing it seemed nearly impossible.

Spray Foam Offers Warmth and Protection

The contractor working on the Joseph Story House had heard of spray foam insulation in the past, and he contacted an InsulStar applicator in the area. The architect, contractor, owners, and spray foam applicators all discussed the idea and decided that spray foam was a great choice for insulation because it would create a continuous seal around the home.

Amazing Results

Applying the spray foam to the 10,000 square foot home was no easy feat, but the owners loved the results. The home is now remarkable energy-efficient and comfortable. It serves as a model for other New England home owners who wish to update their buildings.
