DF/DFP consists of a rigid PVC-U profile containing EPS insulation forming a continuous insulated cavity closer around door and window openings, preventing cold bridging.

Dacatie DF/DFP Frame Formers are suitable for use with all window and door frames, including timber, PVC-U and aluminium. Available in two profiles: DF for cavity widths of 100 mm, and DFP (for internal fixing) for cavity widths of 125–150 mm.

A fully insulated cavity closer made up into a sturdy, factory built frame former saves time by eliminating the need for site fabricated timber templates around window and door reveals.

All Dacatie products are manufactured to ISO9001 and ISO14001 standards. All Dacatie products are chlorofluorocarbon (CFC) and hydrochlorofluorocarbon (HCFC) free, have zero ozone depletion potential (ODP) and low global warming potential (GWP).
