Prefab Houses From the Steel Era
Spray Foam Insulation in Fairless Hills often means insulating a factory-built house. The community took shape in 1951, when Danherst Corporation began erecting prefabricated homes made by Gunnison Magichomes, a wholly owned subsidiary of U.S. Steel. The steel company financed the development with a $50 million loan and named it for its president, Benjamin Fairless; most early homeowners worked at the Fairless Works plant nearby.
Panel-built walls and attics
Prefab homes of that era were built from panels assembled in a factory, and insulation standards were minimal. Panel joints, top plates and the connection between walls and ceiling are common leak points. Many houses also have small attics with low clearance, which limits how much loose fill fits and makes careful sealing more important.
What we usually recommend
First, seal the ceiling plane and add depth where the attic allows it. Second, check the exterior walls; many have thin or no insulation and can take dense-pack or injected fill. Third, look at any additions, which were usually built later, by different builders, to different standards.
Climate
Fairless Hills has a humid subtropical climate, with average monthly temperatures ranging from 32.3°F in January to 76.8°F in July, and sits in hardiness zone 7a. Summer cooling matters as much as winter heating here, and a sealed, well-insulated attic helps with both.

Fairless Hills Questions
Can you insulate the walls of a Gunnison prefab house?
Often yes. We check what is in the wall panels first, then decide whether dense-pack or injection fill works for that construction.
My attic is very shallow. What can go in it?
We seal the ceiling first, then add as much loose fill as fits without blocking ventilation. In very tight spaces, foam on the attic floor can deliver more R-value per inch.
Do you work in the rest of Falls Township?
Yes, including Fairless Hills, the Falls Township sections of Levittown, and the area around Tullytown.
