PRE-INSULATED COPPER PIPES COUPLED BY WELDING. INSULATING SHEATH IN SEAMLESS CLOSED CELLS EXTRUDED PE WITH EMBOSSED PROTECTIVE FILM. EUROCLASS BL s1 d0.

Insulation Features

Insulating material in extruded PE foam, seamless, with closed cells and a very high resistance factor to the diffusion of water vapour. Coupling performed by welding the two embossed films which facilitates separation and reduces installation times.

  • Thermal conductivity at 40°C λ ≤ 0,040 W/m*K
  • Water vapour diffusion resistance factor (anti-condensation) ≥ 15000 μ
  • Fire reaction Euroclass BL s1 d0 (EN13501:2019)
  • Operating temperature -40° ÷ +100°C
  • Does not contain CFCs

Smooth external film in white LDPE with high mechanical resistance.
