FH Forte Fleece Vapour Retarder

Excluding Sales Tax
  • A transparent vapour retarder for the airtight layer in roof and wall constructions. In general FH FORTE Fleece Vapour Retarder is suitable for use in building components that are non-vapour retardant on the outside. In constructions that are well sealed on the exterior (e.g. flat roofs, renovations) the low sd-value guarantees a high degree of drying towards the interior during the summer months. A check should be made in every case by carrying out a calculation (e.g. with WUFI) to ensure the suitability of this option. ISOCELL’s staff will be pleased to offer you technical support. The FH FORTE Fleece Vapour Retarder can also be used for the sub-and-top system in refurbishment.
