Spray Foam Insulation is an insulation and air barrier material that is applicable to lofts, walls, under floors, ceilings, barns, boats, warehouse, commercial properties and seals it against air movement. When sprayed onto the desired surface in a liquid form, spray foam expands and fills all gaps, nooks and crannies. It minimises air infiltration and moisture entrapment, preventing drafts, condensation, cold spots and energy loss.
