Stormproof Casement 78‑56 Timber Window Tooling Sub‑line: Engineered rebates and gasket grooves for unbeatable weather‑seal performance.
System Snapshot
The Stormproof Casement 78‑56 tooling pack produces a robust 78 mm frame partnered with a 56 mm sash, incorporating stepped weather rebates for exceptional exposure resistance. Designed for areas subjected to severe UK wind and rain ratings, the profile accepts double or triple glazing up to 32mm and integrates continuous compression gaskets.
Ideal for: Coastal properties, high‑rise developments, exposed rural sites, schools and public buildings seeking Class 4 air‑tightness.
Design & Performance Highlights
Offset ‘stormproof’ overlap: sash sits proud of frame to shed water and deflect driving rain.
78 mm Frame Depth: ample room for multi‑point locking and concealed trickle‑vents
Thermal U‑values: achieves as low as W/m²K 1.2, with triple glazing and warm‑edge spacer.
64 mm Sash Rebate: accommodates IGUs up to 40mm whilst keeping slim external sightlines.
Discrete Drip Groove: machined underside of the sash to minimise water run‑back.
Opening Variants Supported
Side‑Hung (Left / Right) – standard egress window for quick escape routes.
Top‑Hung – projecting hinge keeps sash clear of rain track when ventilating.
Fixed‑Light – non‑opening sash for matching transoms or sidelights.
