REFORAC flexible foam 1c – soft foam is a specially-formulated PU foam that, thanks to its elasticity, can absorb the movement of components such as those caused in the long term by temperature fluctuations. The strong adhesive properties of the product prevents cracks forming in corners, thus guaranteeing the temperature and sound insulating properties between components such as window frames and masonry walls. Adding moisture (for wetting) further strengthens the fine cell foam structure of the product. The strict ISO 9001/EN 29001 quality standards apply to the development and manufacture of this product.

  • Window installation (clean and controlled filling and application of insulation layers for windows and roller blind cavities) – Filling holes in door posts; but not standalone as a mechanical fix.
  • Filling cavities in wall breaches for all types of facilities and services.
