Advantages

Benefits & advantages

  • high thermal insulation
    Purenit has a very low thermal conductivity, which significantly reduces thermal bridges in the area of the window lintel or installation area.
  • resistance to moisture and putrefaction
    The material is stable even in a humid environment - non-absorbent, not attacked by mould, which extends its lifetime.
  • high strength and stability
    Purenit boxes are strong enough to attach blind and roller shutter systems and other components, while maintaining dimensional stability.
  • easy to work with
    The material can be easily cut, milled or drilled, which facilitates installation on site and adjustments as needed.
  • flame resistance (B2 - according to DIN 4102)
    Purenit is classified as a self-extinguishing material, which increases fire safety of the structure.
