We offer a large selection of expanding foam products for all projects, including kits and expanding foam guns.
Expanding foam is most commonly used for filling ceiling cracks and other holes around the home, such as foundation cracks. It’s also a standard material used for window and door installations as well as around exterior pipes.
Expanding foam, also referred to as spray foam or spray insulation, is made of isocyanate and polyol resin. When the two chemicals come together, they react and expand up to 60 times their liquid volume.
Expanding foam bonds to all building surfaces and materials. It’s resistant to heat, water, and ageing, making it the ideal filler to use for large holes and cracks. Despite being a lightweight product, expanding foam also doubles as a structural support option.
The average expanding foam can support up to three times its weight in pounds per square inch. There are also denser expanding foam products that can support more weight and are also rodent and insect-proof.
Expanding foam has several densities from high to low for you to choose from. The strength you require will depend on what you’re filling or insulating. For example, high density expanding foam is typically used for outdoor and industrial applications, while lower-density products are for insulation and gap filling.
Expanding foam has dozens of applications. It can fill gaps, dampen sound, insulate and stop draughts, and so on. It can be used both outdoors and indoors, from cold storage warehouses to marine flotation insulation.
Depending on your project, you can apply your expanding foam using an expanding foam gun or the aerosol can and applicator it comes with. You can also purchase expanding foam tape, which is ideal for sealing your window frames.
