What Are Sash Windows?

Wondering why sash windows are so popular? Well, that’s easy. It’s their design and functionality, of course. Our sash windows are manufactured in our Wirral warehouse and are made up of double glazed panels that allow a lot of natural light into your property. 


The sash windows work on a vertical slider, allowing you to slide your windows up and down and lock them into place to provide more ventilation in your home during warmer days. Their simple, yet elegant design makes them popular with homes in Liverpool because they’re a timeless classic with a range of modern features, making them the best of both worlds. 

Why Choose Sash Windows?

With such a huge array of double glazing windows Liverpool on offer, you’ll be spoilt for choice! 

Our sash windows are designed with A rated energy efficiency in mind, and as a member of BFRC, you can be certain that our windows meet the highest standards of energy efficiency. This keeps the heat up and the energy bills low in your home.

Since we manufacture our sash windows close to Liverpool in our Wirral warehouse, we can speak of the quality of our work. With our system of runners, springs, and counterbalancing parts, we know that our sash windows open smoothly and will continue to do so for years to come.

Perhaps the most impressive thing about sash windows is their versatility. Want to bring a touch of the classic to a modern home? That works. Or maybe you live in an old property in a conservation area and you need to stick to their original style? If that’s the case, Ultra-Seal’s sash windows can be designed to replace existing windows whilst keeping the new ones true to the old style. 

The simple elegance of a sash window is timeless, but just because their stunning design is from yester-year doesn’t mean their security features are. At Ultra-Seal, we work hard to ensure all our frames are reinforced, our locking systems are police-approved, and our panes are securely fitting into all corners of the frame to prevent would-be intruders. 

Why Choose Ultra-Seal?

So your heart’s set on sash windows (an excellent choice, by the way), but now you’re wondering what makes Ultra-Seal so special? Well…

  • 15 Year Ultra-Seal Guarantee: We guarantee the quality of our windows for up to 15 years, so you know that our sash windows Liverpool are built to go the distance. 
  • 10 Year Insurance Backed Cover: Whilst our guarantee lasts 15 years, we also offer a 10 year insurance backed cover, meaning if the windows should fail in the first 10 years, we’ll replace them for free. 
  • Certass & BFRC Registered Installers: As members of both Certass and BFRC we’re able to prove our professionalism and the quality of our windows. Certass shows that we’re a professional organisation registered with our local council and we’ve proven the quality of our work.

Needed to replace one of my double glazed window units as while stimming my front yard a stone let rip and smashed the outer layer window, was incredibly impressed by the service here the staff here are incredibly helpful and were only to willing to help me to get a window sorted asap, the fact you could see they were also incredibly busy and still be able to squeeze me in was amazing.

Great service, price is competitive and prompt. Ultra-Seal have now installed a new porch and windows on the front of the house, following last year's installations at the back. Excellent job again! I might also add that after 9 and a half year the front door became faulty (10 year guarantee) and was changed for a complete new one with out any hassle. Will always use Ultra-Seal...there fitting crew were excellent throughout.

Just had 6 new windows fitted and they look fabulous. From start to finish was a great experience from Stuart to Mark to the fitting by Darren and Allen who were fantastic workers, polite, obliging and very professional. They left the house spotless. Many Thanks Ultra-Seal.
