RAWLPLUG mounting foam nozzleable universal winter RPS-W 750 ml for up to 45 l yield

RAWLPLUG RPS-W 750 ml is a universal winter-grade mounting polyurethane foam supplied with a nozzle/hose for controlled application. Formulated to cure and expand to approximately 45 liters of foam volume under appropriate conditions, this product is designed for sealing, bonding and thermal and acoustic insulation of joints, gaps and frames in low-temperature environments. The canister format with nozzle enables targeted dispensing for window and door installation, general construction repairs and insulating cavities where winter performance is required.

Advantages

The winter formulation maintains consistent reactivity and cure at lower ambient temperatures compared with standard foams, allowing reliable expansion, adhesion and insulating performance. The included nozzle/hose ensures precise application and reduces waste, while the 750 ml canister provides a yield suitable for medium to large jobs. The cured foam offers filling, sealing and bonding properties combined with thermal and acoustic insulation in building joints and around frames.

Suitable for

• Installation and sealing of windows and doors in cold weather
• Filling and insulating gaps, cracks and cavities in masonry, timber and metal frames
• Thermal and acoustic sealing where winter application is required
• General construction repairs and on-site sealing tasks in low temperatures

When it may not be suitable

This product is formulated for winter use and low-temperature curing; in high-temperature environments other standard or hot-weather foams may perform better with faster curing and different flow characteristics. It is not intended as a structural adhesive for load-bearing connections; for structural bonding or heavy-load fixings, use appropriate mechanical fasteners or structural adhesives.

Key specifications

• Canister volume: 750 ml
• Approximate cured foam yield: up to 45 liters (dependent on substrate and application method)
• Application accessory: nozzle/hose included for precise dispensing
• Temperature performance: formulated for use in low ambient temperatures (winter grade)
• Functions: sealing, bonding, thermal and acoustic insulation

How to use

Shake the canister according to manufacturer instructions before use. Attach the supplied nozzle/hose securely and apply with the canister held upside down for consistent dispensing. Apply foam in layers, allowing partial curing between passes when filling deep cavities to reduce heat build-up and ensure even expansion. After curing, excess foam can be trimmed, sanded and finished or covered with appropriate sealants or trim. Follow safety instructions on the label including ventilation, protective gloves and eye protection.

What to consider before purchase

• Verify that winter-grade foam is required for your ambient temperature and site conditions
• Estimate foam yield needs based on gap size and substrate porosity—actual yield depends on application technique
• Confirm compatibility with materials to be sealed or bonded (masonry, wood, metal, PVC frames)
• Ensure you have appropriate PPE and post-application finishing tools for trimming and sealing

Usage recommendations

For best results when installing windows or doors in cold conditions, pre-wet very porous substrates lightly to improve adhesion, apply foam in layers for deep fills, and allow full cure before trimming or applying finishes. Store unopened cans in recommended temperature ranges and use within the shelf-life specified by the manufacturer.
