| Security | Basic Fitch Fastener | Key-locking Fasteners and Toughened Glass |
The Bespoke Process: From Consultation to Installation
Developing a custom sash window is a multi-stage process that requires accuracy engineering and artisanal ability.

- Lumber Selection and Cutting: The chosen wood is cut utilizing CNC machinery for accuracy and hand-finished by joiners.
- Glazing and Painting: Windows are glazed in a regulated factory environment to guarantee a vacuum seal. They are normally spray-painted with micro-porous finishings that allow the wood to breathe while fending off water.
