Spray Foam Insulation

Unique Spray Foam Insulation Approach for an Older Home in Bristol

In Bristol, PA, we recently completed a unique residential spray foam insulation project that took a less common but highly effective approach. Rather than insulating from the interior, the homeowner opted for exterior application during a complete siding replacement. This allowed for optimal access to the stud cavities, ensuring a seamless and energy-efficient installation.

Exterior Access for Maximum Efficiency

With the sheathing removed, our team applied open-cell spray foam directly into the wall cavities from the outside of the home. Open-cell foam rapidly expands to fill every crack, gap, and irregular space, forming an airtight seal that’s ideal for improving energy performance, especially in older homes like this one.

After spraying, we shaved the foam flush with the face of the studs, making it easy to reinstall siding or add drywall later if needed. This careful, precision-based process maximizes the insulation’s effectiveness without altering the interior layout or disrupting the home’s daily use.

Energy Savings and Long-Term Benefits

By upgrading the insulation from the exterior during siding replacement, the homeowner avoided future disruptions and captured significant energy-saving benefits. Open-cell foam provides superior thermal resistance and air sealing, resulting in lower heating and cooling bills and a more comfortable home year-round.
