{"title":"Expanding Foam Sealants","description":"\u003cp\u003eFill irregular openings and reduce unwanted air movement in suitable areas with the Expanding Foam Sealants collection at FixTimber. Browse straw-applied and gun-applied foams, low-expansion window and door formulas, multipurpose gap fillers, and products intended for cracks, penetrations, cavities, and transitions around compatible building materials. Expanding foam can be useful for selected repair and insulation tasks when applied within the product’s stated limits.\u003cbr\u003e\u003cbr\u003eFoam products vary in expansion rate, density, yield, curing time, temperature range, moisture resistance, fire classification, color, and suitability for interior or exterior use. Low-expansion formulas may be more appropriate around window and door frames, where excessive pressure could distort components. General gap-filling foam may suit larger stationary openings, but it should not be assumed to provide structural support, waterproofing, pest control, or a complete fire-blocking system.\u003cbr\u003e\u003cbr\u003eRead all directions and confirm the maximum recommended gap size, required moisture conditions, application position, ventilation needs, and permitted substrates. Protect nearby surfaces because cured foam can be difficult to remove, and use gloves, eye protection, and other equipment specified by the manufacturer. Do not apply near ignition sources or concealed heat-producing equipment. Exposed foam may require trimming and an approved protective covering. For active leaks, large voids, fire-rated assemblies, or safety-critical penetrations, use an appropriately tested system or obtain professional guidance.\u003c\/p\u003e","products":[],"url":"https:\/\/fixtimber.us\/collections\/expanding-foam-sealants.oembed","provider":"FixTimber","version":"1.0","type":"link"}
