Spray foam insulation requires specialized equipment and skilled professionals for application, which makes it more expensive to install compared to other insulation types.
This ultimately adds to the overall cost of a construction project and may impact the lender’s profitability.
Another significant concern for lenders is that spray foam insulation is often not easily removable, especially in the case of retrofitting or renovation projects. Since it is an adhered material, it cannot be removed easily without damaging the surface it is applied to. This limits future retrofitting and renovation options and may reduce the potential resale value of a property.
Moreover, spray foam insulation traps air within its cells, which can cause potential moisture retention and mold problems. This can be a major concern for lenders, as mold can cause severe damage to the structure of the building and lead to significant health hazards for occupants.
Finally, a lesser-known reason why lenders may not prefer spray foam insulation is due to its fire resistance rating. Polyurethane spray foam is a highly combustible material, and while it is subject to building code standards and is designed to meet certain fire resistance ratings, there is still the potential for the material to ignite and spread flames rapidly.
While spray foam insulation has excellent insulating properties and offers numerous benefits, it may not always be the ideal choice for lenders. The cost of installation, limited retrofitting options, potential mold and moisture problems, and fire resistance ratings, all contribute to lenders’ reservations towards this material.
Lenders must weigh the potential benefits of the material against the cost and risks associated with its installation when considering financing a project that includes spray foam insulation.
