We work with the industry’s leading manufacturers to ensure you receive a high-end product that boasts quality. Hung from the top corners, our sash windows are less likely to distort under their own weight. On top of this, the dry gasket glazed drainage system helps eliminate trapped moisture. Our sash windows are constructed to ensure they last well into the future.

Practical and easy to maintain.

Sash windows are not just an aesthetic solution, but a practical one too.

Each of our sash windows in Surrey have their own unique benefits. Our timber sash windows are classy, strong and durable. Our uPVC sash windows are virtually maintenance free and will not corrode, rot or warp. Our uPVC alternatives look like timber but are more cost-effective, whilst our graceful aluminium sash windows are a resilient and stylish modern edition of the classic style.

All of our sliding sash systems are reinforced too for added security, with each material offering its own benefits.

Each of our Sash windows guarantee a blend of timeless class of an old system and the convenience of modern manufacturing and security!

Technical Information



  • A 128mm outerframe matches timber sash dimensions, making installation simple.
  • Windows can be made up to a maximum size of 1600mm wide and 3000mm high.
  • Large and small sash profiles give equal sight lines to the top and bottom sashes.
  • 150mm and 210mm sills.
  • 10mm/20mm/50mm frame packers.


They have an authentic ovolo shape to the frame, bead, sash and sill; you have the option of adding Georgian bars, sash horns, weather bars and a deep bottom rail (for period properties); and flush gaskets to mimic traditional glazing.



A spiral balance system sits within the frame to counter the sash for smooth motion and the internal glazing bead ensures the window is much more secure than if the beading was on the outside.


Thermally Efficient

The uPVC, timber and aluminium sash window systems are designed to achieve a Window Energy Rating of Band ‘A’. A-rated windows can make a significant different to home energy bills. On top of this, they’re better for the environment too. They even stop energy waste too by preventing draughts with pile seals to the sash and outerframe.
