ELBOWS

A wide variety of shapes and features can be obtained from a block of material by means of CNC cutting machines, given the ease with which rigid polyurethane and polyisocyanurate foams are machined. These products are machined into pipe shells, sections, elbows and can be sold directly or equipped with a vapour barrier in situ. There are two types of vapour barriers available:

  • aluminium-polyester multilayer complex for non-visible applications: T-PIR
  • aluminium-polyester-PVC multilayer complex for visible applications with a great visual appearance, resistant to impacts and the elements: T-PIR+system.

EThese products can be machined using any of the commercialised foams, especially PUR D35, PUR D40, PIR M and CASSPIR.

Technical characteristics

  • Rigid polyurethane or polyisocyanurate foam machined in elbows from a block.
  • Elbows can be supplied with a factory built-in vapour barrier (VB), in which case they are manufactured from pipe shells cut in a mitre joint. Two VB systems are available with the use of PIR M as core insulation:
    • aluminium-polyester multilayer complex for non-visible applications: T-PIR
    • aluminium-polyester-PVC multilayer complex for visible applications with a great visual appearance, resistant to impacts and the elements: T-PIR+system.
