Upgrading sash windows to double glazing

If you are considering fitting double glazed sash and case windows into your property, it is not always necessary to replace the complete window.

If you already have sash and case windows and your existing casement is in good condition, we can manufacture new sashes to fit exactly into the existing box.

This means there is no need to remove panelling and shuttering and offers considerable savings over complete replacement. The case is carefully renovated, the external pointing is renewed, and the windows are fully draught proofed.

Q. What is the Simplex Easy Clean System?

The Simplex Easy Clean System is a very simple way of allowing access to the outside of your sash windows.

The fittings allow you to open the bottom sash like a door, making maintenance and cleaning straightforward.

The easy clean system is the only system for sash windows. It is available in a number of finishes, steel, brass, chrome and satin, to ensure your sash windows are looking their best.

Q. Will my sash windows last for years to come, or should I consider full replacement?

A. The vast majority of sash windows in Edinburgh can be fully refurbished and will outlast a modern replacement. Georgian and Victorian sash windows have been manufactured from slow grown pine which is a far stronger, more durable timber. When your sash windows are fully refurbished they will last another 100 years – as long as the exterior paintwork is maintained.

Q. Can I install double glazed sash windows in my property?

A. For grade A listed buildings the answer will generally be no, but for most other properties it is not a problem. A phone call to the local planning authority will clarify this.

The Scotsman (see below) recently reported that the Edinburgh City Council were reviewing the ban on Double Glazing in certain Conservation Areas.

Q. When cracked glass is replaced will the sash window still be weighted correctly?

A. No, modern glass is 4 mm thick and the original was only 2mm. The windows will need to have additional weights added to ensure a perfect balance.
