Our approach to glass replacement focuses on delivering modern, high-quality features while retaining the elegance of your original windows. We provide glass replacement for traditional timber sash windows and timber casement windows, with ultra-slim double-glazing for superb performance.

And with expert window restoration specialists on-site, we maximise efficiency and cause minimal disruption to you.

Benefits

Ultra-slim, sealed double-glazed units

5-year guarantee

Fits into most single-glazed openings

Warm Edge Spacer Bar reduces perimeter condensation

Approved Document L thermal performance

Elastic dry glazing sealant for durability

The diagram reveals the construction of our sash window replacement glass units.

Two panes of 4mm glass are filled with a heavy gas, which aids acoustic performance.

The inner pane is a Low-E glass, which reflects heat back into the room.

A Warm Edge Spacer Bar (shown in black) reduces perimeter condensation.

We always install the sealed units with 6mm beading to ensure good weather deflection, and to preserve the life of the window for many years.

Heritage sealed units

Classic Heritage slim units incorporate a range of period glasses, to closely replicate the aesthetics of the original glass.

Acoustic performance

The gap between the glass panes is filled with heavy gases, typically Krypton or a Krypton/Xenon mix. This gives a much better acoustic performance than standard Argon-filled units.

The 12mm sealed units we typically install give a 31 dB Rw acoustic rating. Specialist acoustic glazing units are also available, and provide up to 38 dB Rw sound reduction.

Thermal performance

Thermal performance is strong, with typical 12mm units offering a U-value of 1.9 W/m²K. Lower U-values (to 1.3 W/m²K) are also available for units with larger cavities or thicker glass.

Long-lasting glazing sealant

Glass in sash and casement windows is traditionally sealed with linseed oil putty. As this dries, it becomes brittle and pulls away from the frame, allowing water ingress and premature damage to timber and paint.

Instead, we use an elastic sealing compound called Repair Care Dry Seal™ MP, which comes in a choice of finishes and can be painted over. The result is a superior, long-lasting, effective seal.

Both the works and resident liason were an excellent standard and the works were successfully completed to programme and budgets.
