It provides a robust fire-resistant seal for construction joints, service penetrations, door frames, and window surrounds, forming a durable barrier against fire, smoke, and air movement.\u003c\/p\u003e\u003cp\u003eThis foam expands up to 50 times its original volume, effectively filling irregular or wide cavities that conventional fillers cannot reach. Once cured, it adheres excellently to most building materials, including brick, concrete, plaster, metal, and timber. Its formulation supports efficient job site progress, as it allows for cutting, sawing, or plastering just one hour after application. The 750ml size yields approximately 40 liters of cured foam, ideal for professional use.\u003c\/p\u003e\u003cdiv style=\"margin-top:30px;\"\u003e\n\u003ch2 style=\"font-size:22px;font-weight:700;color:#1a1a2e;margin-bottom:16px;\"\u003eProduct Specifications\u003c\/h2\u003e\n\u003ctable style=\"width:100%;border-collapse:collapse;border:1px solid #e0e0e0;border-radius:4px;overflow:hidden;\"\u003e\n\u003cthead\u003e\u003ctr style=\"background:#1a1a2e;\"\u003e\n\u003cth style=\"padding:12px 16px;text-align:left;color:#ffffff;font-weight:600;text-transform:uppercase;font-size:12px;letter-spacing:0.5px;\"\u003eSpecification\u003c\/th\u003e\n\u003cth style=\"padding:12px 16px;text-align:left;color:#ffffff;font-weight:600;text-transform:uppercase;font-size:12px;letter-spacing:0.5px;\"\u003eDetails\u003c\/th\u003e\n\u003c\/tr\u003e\u003c\/thead\u003e\n\u003ctbody\u003e\n\u003ctr style=\"background:#f8f9fa;\"\u003e\n\u003ctd style=\"padding:12px 16px;font-weight:600;color:#333;border-bottom:1px solid #e9ecef;width:45%;\"\u003eSize\u003c\/td\u003e\n\u003ctd style=\"padding:12px 16px;color:#555;border-bottom:1px solid #e9ecef;\"\u003e750ml\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"background:#ffffff;\"\u003e\n\u003ctd style=\"padding:12px 16px;font-weight:600;color:#333;border-bottom:1px solid #e9ecef;width:45%;\"\u003eSales Unit\u003c\/td\u003e\n\u003ctd style=\"padding:12px 16px;color:#555;border-bottom:1px solid #e9ecef;\"\u003eEach\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\u003c\/div\u003e\n\u003ch2\u003eFeatures \u0026amp; Benefits\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eHigh Fire Rating\u003c\/strong\u003e: Achieves Class B1 performance for up to four hours of fire resistance when properly installed.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEffective Gap Filling\u003c\/strong\u003e: Expands significantly to ensure complete coverage in irregular voids and joints.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFast Curing\u003c\/strong\u003e: Ready for trimming or plastering within one hour, minimizing downtime on site.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eStrong Adhesion\u003c\/strong\u003e: Bonds securely to masonry, metal, and timber.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAcoustic Insulation\u003c\/strong\u003e: Closed-cell structure provides effective sound dampening along with thermal and fire-resistant properties.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHand-Held Application\u003c\/strong\u003e: Easy trigger design for direct use, eliminating the need for an applicator gun.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eApplications\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDoor and Window Installation\u003c\/strong\u003e: Creates a fire-rated seal around frames.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eService Penetrations\u003c\/strong\u003e: Fills gaps around pipes, conduits, and cables.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eStructural Gaps and Cavities\u003c\/strong\u003e: Ideal for sealing irregular joints or voids.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThermal and Acoustic Insulation\u003c\/strong\u003e: Reduces heat loss and noise transmission behind cladding and soffit boards.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eInstallation Guidance\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSurface Preparation\u003c\/strong\u003e: Ensure surfaces are clean, sound, and lightly moistened.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eApplication Method\u003c\/strong\u003e: Shake the can vigorously and apply foam in layers.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCuring and Finishing\u003c\/strong\u003e: Allow the foam to cure before trimming or plastering.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eFrequently Asked Questions\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eQ: How long does it take for the foam to cure?\u003c\/strong\u003e\u003cbr\u003eA: The foam cures in approximately one hour, allowing for cutting or plastering.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eQ: Can this foam be used outdoors?\u003c\/strong\u003e\u003cbr\u003eA: Yes, it is suitable for both indoor and outdoor applications.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eQ: What materials can this foam adhere to?\u003c\/strong\u003e\u003cbr\u003eA: It adheres to brick, concrete, plaster, metal, and timber.\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"londonbricks-uk.co.uk","offers":[{"title":"Default Title","offer_id":55516403040641,"sku":"MM_LB1387","price":39.88,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0687\/5329\/3624\/files\/8c0c4881aa906dd8732c8730a101415e.png?v=1775833637","url":"https:\/\/londonbricks-uk.co.uk\/products\/fire-rated-expanding-foam-750ml","provider":"London Bricks UK","version":"1.0","type":"link"}
