Designed to provide a medium-performance fire-resistant seal, it is ideal for construction joints, service penetrations, door frames, and window surrounds. It forms a durable barrier against flame, smoke, and air movement, offering up to two hours of protection.\u003c\/p\u003e\u003cp\u003eThe foam expands approximately 1.5 to 2 times its original volume, making it suitable for filling smaller to medium cavities where controlled expansion is needed. Upon curing, it adheres excellently to most building materials, such as brick, concrete, plaster, metal, and timber.\u003c\/p\u003e\u003cp\u003eCutting, sawing, or plastering can be done just one hour after application, at working temperatures between +5°C and +25°C, facilitating efficient progress on active job sites. The 750ml can size provides optimal yield for professional use, expanding to approximately 1.2 to 1.5 litres when fully cured. Its hand-held format allows for convenient use straight from the can, making it ideal for site convenience or smaller sealing tasks.\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\u003eModerate Fire Rating\u003c\/strong\u003e: Class B2 performance for up to two hours’ fire resistance when correctly installed.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eControlled Expansion\u003c\/strong\u003e: Expands 1.5 to 2 times its can volume, offering a manageable fill for general sealing.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFast Curing\u003c\/strong\u003e: Ready for trimming or plastering within an hour, reducing downtime.\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: Provides sound dampening in addition to thermal and fire-resistant properties.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eConvenient Application\u003c\/strong\u003e: Supplied with a straw nozzle for quick, easy dispensing.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSize\u003c\/strong\u003e: 750ml can expands to approximately 1.2 to 1.5 litres of cured foam.\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 for up to two hours of protection around frames.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eService Penetrations\u003c\/strong\u003e: Fills gaps around pipes, conduits, and cable entries.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eStructural Gaps and Cavities\u003c\/strong\u003e: Suitable for sealing joints in concrete, stone, brick, and plaster.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThermal and Acoustic Insulation\u003c\/strong\u003e: Used behind cladding to reduce heat loss and noise transmission.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eFAQ\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eHow long does it take to cure?\u003c\/strong\u003e The foam cures in approximately one hour, allowing for trimming or plastering.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWhat materials can it adhere to?\u003c\/strong\u003e The foam bonds well to brick, concrete, plaster, metal, and timber.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eIs any special equipment needed for application?\u003c\/strong\u003e No, the foam can be applied directly with the included straw nozzle.\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"londonbricks-uk.co.uk","offers":[{"title":"Default Title","offer_id":55516402844033,"sku":"MM_LB1381","price":34.1,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0687\/5329\/3624\/files\/9db09ef7751f58936274e4454c0bb020.png?v=1775833633","url":"https:\/\/londonbricks-uk.co.uk\/products\/fire-rated-expanding-foam-750ml-high-performance-seal","provider":"London Bricks UK","version":"1.0","type":"link"}
