Double Glazed uPVC Sash Windows
At Colin’s Sash Windows, we are committed to help you with the best suitable windows to give your house a new look. Our uPVC sliding sash windows are manufactured in the UK, supplied nationwide and exported worldwide. Unlike many suppliers, we always give the best price possible to all customers first time – homeowners or trade.
Designed to replicate the traditional timber sash window whilst incorporating the benefits of uPVC. Our sash windows operate like traditional box sash windows – both the top and bottom sashes slide up and down as standard, and most of them tilt inwards for easy cleaning. They are also double glazed, A energy rated. All our sliding sash windows are made-to-measure and delivered to your property ‘ready to fit’. Since they come with a 10-year warranty, you don’t have to worry about your investment.
Tradition With Technology
Our sliding sash windows are manufactured using the SPECTUS uPVC profile designed to truly emulate traditional heritage frames. Featuring woolpile strips that provide an excellent seal against weather, air and debris infiltration. ‘Low E’ glass together with a warm edge spacer bar provide exceptional heat retention, and a superior ‘A’ energy rating. An innovative dedicated weather bar add another level of defense against rainwater – an extra feature unique to this type of window. Designed with not only elegance and authenticity in mind, but security too. The sliding sash windows are multi-chambered and reinforced to prevent deflection through different climates.
Our vertical sliding sash windows ensure that your home retains its character and charm. You can choose from a wide range of styles (including the Georgian sash windows style) features and hardware options to complement your home.

High quality hardware is fixed to integral reinforcements for reliable and smooth opening. The optional travel restrictors stop both the top and bottom sashes from opening more that 100mm. The safety restrictor is non-locking and auto-engages when the sash slides past. They are primarily used as both a safety and security feature. The hooks and pole eyes come loose so you can decide whether you`d like them or not.
As standard, each window is supplied with white furniture including lock, pole eyes and sash pulls. With all optional finishes, you will find exactly the right match for your taste. Heritage style hardware also available.
* Note – our travel restrictors are an extra feature and only available in white, chrome, gold and satin silver

Integral blinds for your sash windows
We’re pleased to offer our sash windows with built in blinds. The double glazing has venetian blinds in between the 2 panes of glass with a magnetic slider control on the left or right side to move them up and down and open/close. They’re available in white, silver and cream colours.
Obviously they’re more expensive than traditional blinds but there are no unsightly cords to get tangled up and they don’t need to be cleaned! With our climate becoming hotter and sunnier at times they’re perfect for deflecting sunlight during the hottest part of the day. Integral blinds cost around £ per sash window (1 blind in the top sash and 1 blind in the bottom).
We offer a bigger range of colours for our normal uPVC windows including blackout blinds which are very popular in children’s bedroom windows and cinema rooms. Please take a look at our Integral Blinds page for more information.
