ISOVER HygroWick® 

ISOVER HygroWick® are coiled pipe insulation sleeves made of glass wool. The insulating sleeve has the shape of a hollow longitudinally divided cylinder made of one segment. The product is provided on the inside with a non-flammable capillary conductive fabric to ensure functionality in insulating cold distribution and on the outside it is provided with a surface treatment with aluminum foil. The longitudinal joints are glued with system perforated aluminum tape to perfectly close the housing and to create a functional and aesthetic covering of the capillary conductive fabric.

APLICATION

Insulating sleeve suitable for cold or dual distribution in the temperature range 0 to 250 ° C, especially for cases where there is also a requirement for non-flammability of insulation (protected escape routes, etc.). The insulation thickness must be at least such that the surface temperature of the cladding is higher than the dew point temperature.

ADVANTAGES

  • non-flammable type of insulation – reaction to fire class A2L-s1,d0
  • very good thermal insulation performance
  • excellent workability – the product can be easily cut with a sharp knife
  • very fast installation – without the need to glue the joints with adhesive
  • constant thermal conductivity over time thanks to the active element (capillary conductive fabric)
  • the only type of insulation that can be applied to pipes in operation
  • the product is made of min. 70% recycled glass
