- Glazing Upgrades: Depending on the customer's requirements, initial glass might be retained, or “Slimlite” double glazing can be installed to improve thermal performance without changing the window's profile.

- Epoxy Resins: Advanced bonding representatives that can stabilize old wood and supply a permanent repair work that is stronger than the wood itself.
- Vacuum Glazing: An ultra-thin glazing alternative (as thin as 6mm) that uses the thermal efficiency of triple glazing while fitting into the original thin rebates of 18th-century sashes.
