Why does adhesion matter beyond appearance?

Poor adhesion can allow moisture and air infiltration behind the foam, undermine its insulating performance, and in some applications affect structural sheathing. Adhesion testing catches this before it becomes a larger problem.

Spray Foam Adhesion Testing | Spray Foam Testing Services

Foam that looks fine on the surface can still be poorly bonded underneath — a condition called delamination that isn't visible without testing. Adhesion testing checks the bond between the foam and the substrate (framing, decking, or masonry) using pull-test methodology, identifying separation before it becomes a structural or moisture problem.

What We Check

Bond strength between the foam and the substrate at sampled points
Visual and physical signs of delamination or separation
Surface consistency and cure quality
Risk factors for future adhesion failure (substrate prep, application conditions)
Written findings with photo documentation

Who This Is For

Homeowners or buyers concerned about foam that looks loose, bubbled, or separated from framing
Contractors and manufacturers wanting independent verification of a disputed install
Attorneys and insurers evaluating a spray foam adhesion failure claim

Frequently Asked Questions

Delamination is when cured spray foam separates from the substrate it was applied to — framing, roof decking, or masonry — even though it may look intact on the surface. It's a bonding failure, not just a cosmetic issue, and it isn't reliably visible without testing.
