Bostik Evo-Stik Expanding Spray Foam Filler - 500ML

It is critical to maintain continuity and ensure that no gaps or spaces are left uninsulated. This would result in higher energy bills, owing to heat and energy loss through these gaps. However, it is quite difficult to insulate awkward bends on a pipe or the irregular spaces on the plasterboard or fill gaps in the insulation. This difficult task is made easy using Bostik Evo-Stik expanding spay foam filler.
