Guaranteed Safe Checkout

PHS Airtight Foam is an airtight PU expanding foam, specially developed to form an airtight, thermal and sound insulating interface between construction components. It properties include thermal insulation, sound dampening, high elasticity on curing and airtightness.

Applications:
  • 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, can be used on various substrates like masonry, plaster, wood, concrete, aerated concrete, bricks, clinker, plasterboards, fibreboards, various plastics, corrosion protected metals, Styrofoam, various other insulating materials, rigid foam panels, ceramics, tiles, stone.
  • Adheres to all common building materials, with the exception of polyethylene, silicone, oils and greases, mould release agents, etc.
Features & Benefits:
  • 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.
  • Resistance to aging, but not to UV radiation.
  • Offers excellent thermal and sound insulation values.

Application

Application Guide:

  1. The adhesive surfaces must be free of dirt, dust and grease.
  2. Slightly moisten the building connection joint with a water spray.
  3. The optimal processing temperature is +20° C to +25°C.
  4. Shake the can thoroughly before use.
  5. Fill the joint no more than halfway, because the fresh foam expands to 2-3 times the initial volume.
  6. Foam layers thicker than 5cm in several steps and allow each layer to harden.
  7. The foam cures more effectively and quickly when additional moisture is present in the substrates.
  8. Moistening is recommended for all joints after applying each layer of foam.
  9. Insufficient supply of moisture or excessive moisture can lead to unwanted shrinkage of the foam.
  10. Never press the partially hardened foam into the joint.
  11. Remove fresh foam stains immediately with foam cleaner. This can only be done in the tack-free period.
  12. Hardened foam can only be removed with special cleaner or mechanically.
