{"title":"Foam Sealant","description":"\u003cp\u003eSpray foam is one of the most versatile sealing materials in the construction industry: it can fill gaps, be used for window and door installation, and solve thermal and sound insulation tasks all with a single material. Its ease of use has made it popular even among non-professionals — but incorrect application results in just as faulty an outcome as with any other material.\u003c\/p\u003e\n\u003ch3\u003eWhat is spray foam?\u003c\/h3\u003e\n\u003cp\u003eSpray foam is a one-component or two-component polyurethane foam that expands after application to fill cavities and gaps, then cures. Once cured, it forms a solid foam with thermal insulation, soundproofing properties, and mechanical stability, which can be cut, sanded, and painted.\u003c\/p\u003e\n\u003ch3\u003eWhat is spray foam used for?\u003c\/h3\u003e\n\u003cp\u003eFor window and door installation: Spray foam seals the gap between the frame and the wall opening — providing fixation, thermal insulation, and sealing functions simultaneously.\u003c\/p\u003e\n\u003cp\u003eFor filling indoor and outdoor gaps: At mechanical penetrations, pipe passages, and structural gaps.\u003c\/p\u003e\n\u003cp\u003eFor thermal and sound insulation applications: Closed-cell spray foam variants offer good thermal insulation; open-cell variants are primarily suitable for soundproofing.\u003c\/p\u003e\n\u003ch3\u003eFire-resistant spray foam\u003c\/h3\u003e\n\u003cp\u003eAt fire-critical joints — such as mechanical penetrations through fire-rated walls or openings in stairwell walls — fire-resistant (intumescent) spray foam must be used. This foam expands when exposed to fire and seals the opening. It cannot be replaced with standard spray foam.\u003c\/p\u003e\n\u003ch3\u003eWhat should you pay attention to during application?\u003c\/h3\u003e\n\u003cp\u003eSpray foam expands by 30–50% beyond the cavity volume during curing — the amount applied must be adjusted accordingly. Too much foam can deform the window frame. Pre-wetting the substrate (with a fine water mist) speeds up curing and improves adhesion. Excess foam can be trimmed off with a sharp knife after curing.\u003c\/p\u003e\n\u003cp\u003eBrowse our selection of spray foams or request advice to choose the right foam type and fire protection class for your application.\u003c\/p\u003e","products":[{"product_id":"kerakoll-hyper-foam-combi","title":"Kerakoll Hyper Foam Combi","description":"\u003cp\u003eSelf-expanding foam for filling and fixing.\u003cbr\u003e\u003cbr\u003e Kerakoll Hyper Foam Combi can be used with a spray gun or by hand with the applicator nozzle.
