When sealing gaps and penetrations in construction, you need more than just a filler. You need durable insulation and sound dampening that performs for years. MapePUR Universal Foam M delivers a stable, closed-cell fill that insulates against thermal transfer and sound, resists moisture, and prevents mould. It’s the right foam for a robust, energy-efficient build.
MapePUR Universal Foam M is a one-component expanding polyurethane foam engineered to fill, seal, and insulate gaps across diverse construction applications. It forms a stable, closed-cell structure with excellent mechanical characteristics, providing significant thermal and acoustic insulation. This foam is waterproof, resistant to temperatures from -40°C to +90°C, humidity, ageing, and mould formation. Its CFC-free formulation ensures environmental responsibility, setting it apart from basic fillers by delivering comprehensive performance in a single product.
Every performance metric in MapePUR Universal Foam M supports a more durable, energy-efficient building envelope:
MapePUR Universal Foam M applies easily with its hand lever, simplifying precise filling. Substrates must be clean, dust-free, and oil-free. For optimal expansion and hardening, dampen surfaces with water before application. Shake the can well for 30 seconds, then hold it upside down. Fill the gap from the lowest point upwards, aiming for 50-60% volume as the foam expands to complete the fill. For continuous work, shake the can periodically. Excess uncured foam can be cleaned with MapePUR Cleaner. Once hardened, the foam can be cut, sanded, drilled, or skimmed before painting to finish the surface. For gun-applied precision, consider MapePUR Universal Foam G with the MapePUR Gun Standard.
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.

| Sealing construction features on roofs | Prevents air and moisture leaks, contributing to overall building envelope integrity. | Roofers, builders |
| Bonding electrical fittings | Secures electrical boxes and conduits in place while providing insulation. | Electricians |
| Sealing formworks for concrete pouring | Prevents concrete bleed, ensuring cleaner edges and preventing waste. | Concrete formworkers |
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.
