PHS Airtight Spray Foam

PHS Airtight Spray Foam is specially developed to form an airtight, thermal and sound insulating interface between construction components.



PHS Airtight Spray Foam is specially developed to form an airtight, thermal and sound insulating interface between construction components.


• Adheres to all common building materials, with the exception of polyethylene, silicone, oils and greases, mould release agents, etc.
• Can be processed at temperatures from +5°C to +30°C.
• Hardened foam is elastic, predominantly closed-cell, rot-proof, moisture-proof, temperature-resistant from -50°C to +100°C.
• Resistant to aging, but not to UV radiation.
• Offers excellent thermal and sound insulation values.


• The adhesive surfaces must be free of dirt, dust and grease.
• Slightly moisten the building connection joint with a water spray.
• The optimal processing temperature is +20° C to +25°C.
• Shake the can thoroughly before use.
• Fill the joint no more than halfway, because the fresh foam expands to 2-3 times the initial volume.
• Foam layers thicker than 5cm in several steps and allow each layer to harden.
• The curing of the foam is supported and accelerated by additional moisture in the substrates (moistening of the substrates).
• For all joints, moistening is recommended after each layer of foam.
• Insufficient supply of moisture or excessive moisture can lead to unwanted shrinkage of the foam.
• Never press the partially hardened foam into the joint.
• Remove fresh foam stains immediately with foam cleaner. This can only be done in the tack-free period. Hardened foam can only be removed with special cleaner or mechanically.

 • PHS Spray Sealing Foam is suitable for windows, attic conversion, doors, walls, corner joints, air conditioning and ventilation systems, pipelines, wooden structures.
• Designed to fill and seal around gaps, cracks and penetrations in the building envelope to stop air infiltration, maintain thermal integrity and reduce the transfer of noise.
• Very versatile, therefore it can be used on various substrates like masonry, pla- ster, wood, concrete, aerated concrete, bricks, clinker, plasterboards, fiberbo- ards, various plastics, corrosion protected metals, styrofoam, various other in- sulating materials, rigid foam panels, ceramics, tiles, stone.
