• Also suitable for subsequent installation
• Chamber length 50 cm incl. continuous removable insulation core WLG* 040
• Insulation core with 12 cm diameter can be pushed up to the vapour retarder in the corresponding core hole of the thermal insulation level without causing a thermal bridge

Flange collar optionally available in:

• Flange collar made of bituminous membrane (PYE PV 200 S4 sanded surface)
• rigid PVC
• PVC roofing sheet, Resitrix or Elevate

In the version with flange collar made of bituminous membrane, the flange collar is root penetration resistant in accordance with EN 13948.

*WLG describes the thermal conductivity group of a construction (insulation) material and indicates the thermal conductivity of a material for a thermal flow. The thermal conductivity of polystyrene, at 040, is particularly low, it is therefore optimally suitable for reducing heat losses (thermal insulation) and action of heat (cold insulation).
