Traditional Designs for Sash Windows
At Spectrum, we know how important it is to maintain period properties. If you live in a conservation area or a listed building, sliding sash windows may be important to preserving the architectural style. We think that uPVC sliding sash windows are perfect for you.
With uPVC, these sash windows are more weatherproof than ever before. Compared to traditional timber, there’s much less yearly maintenance required. You can make sure that you choose new uPVC sliding sash windows that will improve your energy efficiency, with an ‘A’ rating, and argon filled units are available upon request.
As a Certass accredited team, we provide deposit protection, insurance backed policy, and an easy way to register your installation. Make sure you're choosing a competent person.
10 Year Warranty
We ensure a ten year warranty on all of our double glazing products, along with a 12 month maintenance check for your peace of mind. That's our pledge in offering you quality assurance.
Extra Features for Sash Windows Colchester
When designing your next uPVC sliding sash windows look through the extra features we offer, like customisable hardware to match your existing designs. If you’re looking specifically for heritage designs, choose our run-thru sash horns astragal or Georgian bars. Your uPVC sliding sash windows will look truly authentic with this attention to detail.
Plus, you can improve the security of your uPVC sliding sash windows with a few additions. We offer toughened glass and security bars to discourage intrusion, especially hard impacts. Furthermore, with the addition of travel restrictors can make them safer for children.

A sliding sash window refers to a window with sashes that slide upwards, downwards (or, in this case, both). This is compared to casement windows which typically have a hinge pivot and typically pivot from the side (side hung) or the top (top hung).

"The fitting guys were a great laugh, enjoying several cups of tea! Everything was left really tidy and cleaned up well and I got to enjoy my conservatory for the end of this “supposed British summer”. We are now looking at getting our windows replaced with them as well, thoroughly recommend."

"Fantastic job from the guys that fitted our new sash windows, we originally chose white but changed our minds after seeing an oak effect one in their office when we went to drop off a cheque. So glad we did, we’ve had so many compliments from people."

"Couldn’t be happier with my new conservatory, having to now work from home, we needed the extra office space. We didn’t have a huge budget but we were able to get what we needed, perfect escape from the rest of the house!"

"I have recently had a conservatory built & I couldn't be more happier with the result. Build finished April 2022. The workmen were great, on time every day & a good laugh. The quality of workmanship was excellent. Richard & Kelly checked on the build almost daily, to see if everything was alright. If you had any questions or concerns, they were more than happy to assist. They paid attention to every little detail. Even when they were on holiday. Thank you to James, Ross, Gareth, Ryan, Rob, Richard & Kelly, for building a beautiful place for me to relax."

"Spectrum glazing where brilliant when choosing and building our new conservatory. They designed exactly what we wanted with Ultraroof, which is a brilliant idea and makes the room useable all year round. All members of staff are helpful and always available for assistance. The workmen used are professional and hardworking (even coming in awful weather). Overall, I'm very happy with the finished outcome of our new conservatory and very pleased we chose Spectrum Glazing over the other big named companies. If I had any more windows or doors needing doing I'd be using these guys will recommend to people as well. Thanks again guys!"

"Absolutely over the moon with our conservatory! Would 100% recommend this company, they listened to what we wanted and the result is better than what we imagined! The whole building team were also amazing. Thank you so much Spectrum Glazing! ⭐️⭐️⭐️⭐️⭐️"

"Really impressed with the service (and price) of the windows we got (five windows front and back). We've had them in for over a year and not had any problems - in fact the only problem we had was on the day of install they couldn't get the biggest of the frames up our tight staircaise - but this was solved easily with them sorting a scaffolding thing to lift it up from the outside. Very happy with everything and I would definitely use them again."

"Couldn't be happier with both the end result and the service. We chose a local family run company for good reason, we have been burnt by the big guys before. From the initial planning by Rob who knows his stuff, planning and working with us to get exactly what we wanted, through surveys, and almost weekly site visits from Richard and kelly checking the standards and progress. I can't thank the fitters, Gareth & Ross enough, you guys worked through the november storms never wanting to slow the job down. Absolutely 5* service throughout. Were they the cheapest? No, but not the dearest either! you can't go cheap on a project like this, extending your home. They worked with us to complete by Christmas and again, Spectrum delivered...... literally. You get what you pay for and with spectrum we got 1st class."
