Double Glazed uPVC Sash Windows

upvc sash window white

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 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.

Fabulous uPVC Sliding Sash Windows! We have never had any complaints about the quality. You won’t be disappointed by our competitive prices. Check our measuring guide, get your sizes and ask for your sash windows online quote!

Tradition With Technology

Our sliding sash windows are manufactured using the EVOLVE uPVC profile designed to truly emulate traditional heritage frames. Featuring brush seals around the openings for exceptional draught proofing and to assist the environment. ‘Low E’ glass together with a warm edge spacer bar provide exceptional heat retention, and a superior ‘A+’ energy rating. 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 differing climates.

Our vertical sliding sash windows ensure that your home retains its character and charm. You can choose from a wide range of styles, features and hardware options to complement your home.

Choose from a wide range of colours.

As standard our sash windows come in a smooth white finish but you can also have them sprayed in any RAL or Farrow & Ball colour.

If you want a more natural look our woodgrain colour selection is the right choice. The foiled finishes bring windows to life with a woodgrain effect that never needs painting. Dual colour finishes are also available: meaning a coloured exterior can be paired with a smooth white interior to keep its effect on the room neutral.

We are now offering woodgrain windows with seamless welds making the joints almost invisible.

High quality hardware is fixed to integral reinforcements for reliable and smooth opening. The travel restrictors stop both the top and bottom sashes from opening more that 100mm. The standard 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, sash pulls and safety restrictors. With all optional finishes, you will find exactly the right match for your taste. Heritage style hardware also available.

 

* Note – our travel restrictors are only available in white, chrome, gold and satin silver
