Gap fillers solve the problem of drafts and heat loss in living spaces. They seal tiny openings and gaps around windows, doors, sinks, etc. Premium gap fillers complement home insulation by providing additional air-sealing abilities and water resistance.

Note: Gap filler foams are perfect for sealing narrow cracks and joints, but they’re not a substitute for spray foam insulation when you need full-surface thermal protection.

What Are Gap Fillers and Why Are They Essential?

Gap filler is a material used to fill a building's gaps, holes, and cracks. It is made using polyurethane-based polymer, which expands rapidly upon application. Gap fillers block air, moisture, pests, and other elements from having access to your space. They are used to seal tiny spaces in windows, doors, walls, kitchens, plumbing systems, etc.

Gap fillers provide excellent air sealing abilities that help prevent air infiltration and drafts in buildings. They are also applied as a crack filler. Gap fillers improve energy efficiency by reducing heating and cooling bills. They prevent moisture damage, maintaining structural integrity in buildings. Gap fillers possess strong adhesion, making them bond easily with different materials such as metals, ceramics, wood, and plastics.

How Do Gap Fillers Improve Home Insulation?

Gap fillers improve home insulation by providing additional air-sealing capabilities. They prevent air leaks by sealing holes, gaps, cracks, and openings in the building.
