Sash Windows Specifications: Get To Know Your Windows

Wednesday, February 13th , 2013

Windows are an aspect of your home that you’ll never really notice until something isn’t quite right; whether it’s the deteriorating appearance of the frames or the lack of energy efficiency, if your windows aren’t meeting high standards then your home will never be the way you’d want it.

Here at Bygone Windows we specialise in the manufacture and supply of sash windows that meet exceptionally high standards of quality. We pride ourselves on the quality of our products so we’d like you to get to know them a little better:

Energy Saving

Our windows are BFRC ‘A’ rated and we are Energy Savings Recommended by the Energy Savings Trust.

Improving your home’s energy efficiency can reduce your energy bills and your carbon footprint and our recommended windows can help.


Bygone sash windows come with a luxurious white painted timber or antique cream effect finish to ensure that your windows complement and enhance your home’s traditional charm.


Windows and doors are a prime entry point for criminals, which is why the security features of your windows are so important. Thanks to continuous development of our products, our windows are ‘Secured by Design’ and a police preferred product.

Ease of Use

We have designed our windows to be as easy to use and as easy to clean as possible. We fit tilt restrictors to all of our sash windows to ensure that cleaning your windows is a stress-free process!

When investing in new windows it’s important that you consider every aspect from energy efficiency to security; if you decide on substandard windows, every aspect of your home can suffer and you’ll find that you’ll need to replace them much sooner than you’d hoped.

There are a whole host of other specifications and details of our windows available on our site, please feel free to browse or contact us directly if you have any questions or queries.
