Howdens Expanding Foams

Repair cracks and holes or insulate cavities with these expanding foams. Offering strength and resistance to damp, they are quick and easy to apply and suitable for both internal and external use. They can fill gaps in stone, brick, plaster, or concrete, and leave a tidy, professional finish. Often used for fixing window and entranceway frames, expanding foams can also create a watertight seal between a floor and a baseboard, or around radiator pipes. Some designs expand by up to 30 times their original size to provide effective insulation in wall cavities - great for stopping draughts or reducing noise levels. They come in a choice of handheld or gun-grade forms, making it easy to select the most convenient for the job.
