For sealing door and window frames, roller-blind housings, and structural gaps against air leaks and heat loss, MapePUR Universal Foam M/G provides a rapid-hardening polyurethane barrier. 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.
The 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.
This foam is suitable for the following jobs:
Ensure the substrate is clean, dust-free, and free from grease, oil, or loose material. Mask adjacent delicate surfaces to protect them from overspray. Pre-dampen the substrate by spraying it with water to accelerate expansion and ensure optimum polymerisation.
The application temperature must be between +5°C and +30°C, with optimal performance achieved when the can is between +20°C and +25°C. Shake the can upside down for at least 30 seconds before use, and repeat shaking after any long interruption.
For gaps wider than 5 cm, apply the product in multiple layers, waiting for each layer to expand before applying the next. Spray the freshly extruded foam with water immediately after application to improve yield and curing speed.
Yes, this foam is formulated for the thermal and sound insulation of door and window frames. Its rapid curing and adhesion properties make it suitable for these applications.
Yes, the foam offers a soundproofing capacity of 58 dB (EN 12354-3 or ISO 717-1). This helps reduce acoustic leakage when filling gaps in building materials.
The foam is classified as B3 under DIN 4102, which indicates flammability. It is not a fire-rated or non-combustible foam and should not be used where specific fire resistance is required.
It adheres well to common building materials such as brickwork, concrete, gypsum, wood, metal, glass, foam polystyrene, PVC, and rigid foam polyurethane. Always ensure surfaces are clean and prepared.

Store in an upright position between 10°C and 25°C. Keep away from heat and direct sunlight. The shelf life is 18 months from the production date when stored correctly. Dispose of empty cans according to local regulations.
Proper substrate preparation ensures maximum adhesion and foam performance for MapePUR Universal Foam M/G.
This includes brickwork, concrete, gypsum, wood, metal, and glass.
Surface prep: Clean and prepare the substrate. Ensure surfaces are free from dust, grease, and loose particles. Dampen the substrate with water before application to assist curing and adhesion.
Primer: Not required. Dampening the surface with water acts as the pre-treatment.
This includes foam polystyrene, PVC, and rigid foam polyurethane.
Surface prep: Clean surfaces thoroughly. Ensure they are free from release agents or contaminants. Dampen with water.
Primer: Not required. Dampening with water is sufficient for these surfaces.
