Retain the Character of Your Property

Character sells

Estate agents will tell you: original sashes, timber casements and mullioned stone windows add measurable value. UPVC replacements typically take value off — the room feels wrong and the front elevation loses coherence.

Invisible from outside

Because the whole install sits on the room-side of the primary window, the front of the building is completely unchanged. Slim aluminium sight-lines behind the original glass are barely visible from the street.

• No change to the elevation
• Original glass stays visible
• Slim internal sight-lines
• White, black or heritage colours

Best of both worlds

You keep the sash cords, the wavy glass and the deep reveals — and you get the warmth, quiet and draught-proofing of a modern window. That's the whole point of the product.
