65 Series Thermal Break Casement Window
The volume workhorse: 1.5 mm walls, 15 mm thermal break, 32 mm glazing groove and a price that still works on 200-unit projects.

YFG90 Three-Cavity Integrated Screen System Window
One frame. Three cavities. Screen, glass and sash in a single plane.
01 — Overview
Engineered detail, not marketing copy.
YFG90 is the window we specify when a project cannot afford to compromise: deep 90 mm frame, 2.0 mm load-bearing walls, three independent thermal chambers and a 25 mm visible face that keeps sightlines quiet. The stainless insect screen sits flush inside the frame instead of bolted on the outside, so ventilation no longer costs you the view or the finish.

Any RAL, matched to sampleRAL-CUS
Powder coating at 40–80 μm on a chromated pre-treatment, in a matte, satin or anodised finish. Teak and walnut sublimation are available, and any RAL can be matched from a physical sample. Colour boards are sent for approval before production.
04 — Design details
The detail is the difference.
Three cavities, not one
The frame is divided into three closed chambers. Each one interrupts heat transfer, and the outer two carry drainage away from the inner seals.
Screen without the visual cost
The 304 stainless mesh runs in its own track inside the frame, flush with the sash. From inside you see one clean line, not a bolt-on box.
Engineered for driven rain
Stepped drainage, pressure-equalised chambers and three EPDM sealing lines deal with wind-driven rain instead of relying on a bead of silicone.
Hardware that survives humidity
Multi-point locking with stainless internals; handles and hinges tested for coastal air rather than dry inland air.
