- Timber
- Solid Dark Red Meranti, kiln-dried to 9–11% moisture, high density 450–500 kg/m³, or veneered marine plywood.
- Hardware
- Small “anuba” hinges; the sash locks with clips and an angled knob.
Painting
Painting takes place in robotic electrostatic painting facilities:
Impregnation
The window is sprayed and fully flooded with fungicidal preservatives in a flow-coating chamber.
Drying
In a closed room with controlled temperature and humidity, followed by sanding of the surface by machine and by hand.
Robotic electrostatic painting
A four-stage cycle with varnish and colourants or RAL colours. Every stage is followed by the necessary drying time, sanding and strict quality control, up to the final coat.
