It is designed for sealing, filling, and insulating where enhanced fire protection is required.\u003c\/p\u003e\u003cp\u003eDeveloped for passive fire protection, it provides a reliable barrier against the spread of fire, smoke, air, and moisture in structural gaps and penetrations.\u003c\/p\u003e\u003cp\u003eThe foam cures with ambient moisture to form a dense, semi-rigid cellular structure offering both fire resistance and acoustic insulation. Once cured, it remains stable under temperatures from -40°C to +90°C, maintaining structural integrity and long-term adhesion to most construction substrates including masonry, timber, and metals.\u003c\/p\u003e\u003cp\u003eEquipped with a patented adapter system, the 600ml can allows precise, single-handed application with full control over flow and dosage, reducing waste and ensuring even filling of cavities. The formulation is completely free from HCFC and CFC propellants, providing a more sustainable, environmentally responsible alternative.\u003c\/p\u003e\u003cp\u003eWith an expansion rate of approximately 135% during curing and minimal post-expansion once set, this foam ensures consistent joint sealing, excellent acoustic reduction (58 dB), and thermal conductivity of just 35.4 mW\/m·K.\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;\"\u003e600ml\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\u003eFire Resistance (B2 Rated):\u003c\/strong\u003e Offers effective flame-retardant performance in fire-rated construction joints and penetrations.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHigh Filling Capacity:\u003c\/strong\u003e Expands up to 135% during curing to fill large gaps, voids, and irregular cavities efficiently.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eExcellent Adhesion:\u003c\/strong\u003e Bonds strongly to most building materials including concrete, brick, stone, wood, and metal, excluding PE, PP, and PTFE.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAcoustic Insulation:\u003c\/strong\u003e Delivers high sound reduction performance up to 58 dB, ideal for noise control in partition and service wall applications.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThermal Insulation:\u003c\/strong\u003e Enhances energy efficiency with a thermal conductivity value of 35.4 mW\/m·K.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eStable and Durable:\u003c\/strong\u003e Maintains volume and structure with less than 5% shrinkage and no post-expansion after curing.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEnvironmental Safety:\u003c\/strong\u003e Propellant gases are HCFC- and CFC-free, ensuring no harm to the ozone layer.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEase of Application:\u003c\/strong\u003e The system allows precise, comfortable, and controlled one-hand use without the need for additional tools.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTemperature Resistance:\u003c\/strong\u003e Retains performance between -40°C and +90°C once fully cured.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eFrequently Asked Questions\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eQ:\u003c\/strong\u003e Can this foam be used outdoors?\u003cbr\u003e\u003cstrong\u003eA:\u003c\/strong\u003e Yes, it is suitable for both indoor and outdoor applications.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eQ:\u003c\/strong\u003e Does the foam adhere to plastic?\u003cbr\u003e\u003cstrong\u003eA:\u003c\/strong\u003e It adheres well to most materials except PE, PP, and PTFE.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eQ:\u003c\/strong\u003e Is any additional equipment needed for application?\u003cbr\u003e\u003cstrong\u003eA:\u003c\/strong\u003e No, the adapter system allows for easy, controlled application without extra tools.\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"londonbricks-uk.co.uk","offers":[{"title":"Default Title","offer_id":55516345532801,"sku":"MM_LB205","price":25.8,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0687\/5329\/3624\/files\/5a359487ff24fb188456a654e874c544.png?v=1775833197","url":"https:\/\/londonbricks-uk.co.uk\/products\/fire-acoustic-expanding-foam-600ml","provider":"London Bricks UK","version":"1.0","type":"link"}
