It expands on contact with atmospheric moisture to fill deep cavities, forming a stable closed-cell structure that adheres to common building substrates including brickwork, concrete, gypsum, wood, metal, glass, foam polystyrene, and PVC.\u003c\/p\u003e\n\n \u003ch3\u003eHow it works\u003c\/h3\u003e\n \u003cp\u003eThe one-component prepolymer mixture reacts with humidity to expand and fill irregular voids. The cured foam functions as both a thermal insulator and an acoustic barrier, offering a soundproofing capacity of 58 dB to reduce transmission through partition walls, service penetrations, and window reveals. It resists water penetration, mould growth, and service temperatures from -40°C to +90°C. Once fully hardened, the yellow foam can be mechanically worked by cutting, sanding, grinding, drilling, or painting, and it can be skimmed directly with cementitious renders.\u003c\/p\u003e\n\n \u003ch3\u003eNumbers that matter\u003c\/h3\u003e\n \u003cul\u003e\n \u003cli\u003e\n\u003cstrong\u003e58 dB soundproofing capacity:\u003c\/strong\u003e Rated under EN 12354-3 or ISO 717-1 to isolate acoustic flanking paths through structural gaps and frames.\u003c\/li\u003e\n \u003cli\u003e\n\u003cstrong\u003e0.036 to 0.039 W\/m K thermal conductivity:\u003c\/strong\u003e Low thermal conductivity (DIN 52612) to prevent thermal bridging around door frames, window fittings, and roof penetrations.\u003c\/li\u003e\n \u003cli\u003e\n\u003cstrong\u003e25 to 30 minutes cut window:\u003c\/strong\u003e Minimum waiting time before the hardened foam (at Ø 20 mm, +20°C, and 60% R.H.) can be safely cut back for finishing.\u003c\/li\u003e\n \u003cli\u003e\n\u003cstrong\u003e1.5 to 5 hours full cure:\u003c\/strong\u003e Complete hardening window depending on temperature and moisture levels, allowing fast turnaround before skimming or painting.\u003c\/li\u003e\n \u003cli\u003e\n\u003cstrong\u003e45 litres free expansion yield:\u003c\/strong\u003e High volumetric yield from a single 750 ml can (measured at +20°C and 60% R.H.) to maximize coverage in large cavities.\u003c\/li\u003e\n \u003c\/ul\u003e\n\n \u003ch3\u003eWhere to use it\u003c\/h3\u003e\n \u003cp\u003eThis foam is suitable for the following jobs:\u003c\/p\u003e\n \u003cul\u003e\n \u003cli\u003eThermal insulation and soundproofing of door frames, window frames, and roller-blind housings.\u003c\/li\u003e\n \u003cli\u003eFilling and insulating gaps between different building materials and external insulation systems.\u003c\/li\u003e\n \u003cli\u003eFixing support frames in place for door and window fittings, and filling the gaps between frames and walls.\u003c\/li\u003e\n \u003cli\u003eInsulating through-pipes for heating, air-conditioning, and cooling systems.\u003c\/li\u003e\n \u003cli\u003eFilling and insulating construction features and fittings on roofs and flat roofs.\u003c\/li\u003e\n \u003cli\u003eBonding embedded electrical fittings such as cable-runs and junction boxes in plasterboard walls.\u003c\/li\u003e\n \u003cli\u003eSealing formwork to prevent leaks when pouring fluid concrete.\u003c\/li\u003e\n \u003c\/ul\u003e\n\n \u003ch3\u003eLimitations\u003c\/h3\u003e\n \u003cul\u003e\n \u003cli\u003eDoes not adhere to polyethylene, silicone, or Teflon.\u003c\/li\u003e\n \u003cli\u003eCured foam must be protected from direct UV exposure to prevent surface degradation and damage.\u003c\/li\u003e\n \u003cli\u003ePressurised cans must not be exposed to direct sunlight or temperatures exceeding +50°C.\u003c\/li\u003e\n \u003cli\u003eUncured foam cleanup requires solvent-based MapePUR Cleaner, which may discolour sensitive substrates; verify compatibility via a test area before use.
