Are Sash Windows Secure?

Our sash windows security locks and durable materials make them highly secure. Homeowners can have peace of mind thanks to our sash window security bolts and PAS 24 accreddited upgrade package. Older timber sash window locks won’t be able to come close to the contemporary sash window safety features that come with the Quickslide Legacy uPVC system! Our window sashes are made from durable uPVC and don’t use the standard pully and countweight system. Instead the vertical sliding window system works via a specialised spring system making them much harder to break open.

Do You Have Classic Sash Window Styles?

Yes, we can supply all sorts of authentic looking period sash windows, including Victorian windows, Georgian, Edwardian, and even curved varieties. We have a massive selection of woodgrains and colours, and our collection of optional features lets you design the perfect window to suit your next project for your customers.

Georgian windows are recognised by their “six over six” design, while Victorian windows have clearer sightlines via a “four over four” design. Edwardian windows sit in the middle with a mix of the two astragal bar styles.

What Are Old-Style Sash Windows?

Historic sash window design is typically a timber or timber-looking window, with run-through horns, deep bottom rail, slim mid-rail, and astragal bars. With Quickslide, you can install windows that mimic all of these old-style features while incorporating all the modern benefits of uPVC and bespoke double glazing. Unlike old-styles, our modern sash windows don’t have cords, making them much more durable and long lasting. New sash windows have all sorts of marvelous features that can make them much more desirable compared to timber systems.

What Is A Sliding Windows?

Sliding windows, sliding sash windows, vertical sliders, or just sash windows are all names for a design where the window has two sashes that slide against each other to open and close. A timeless classic, these windows have been around much longer than casement windows or mock sash ones.

What Is A Window Sash?

The sash is the part of the window that moves, while the frame is the section that is fused and fixated to the wall. The sash sits inside the frame and can typically be moved back and forth, up and down, or left and right depending on the design.

Do You Do Sash Window Repairs?

While we don’t repair sash windows, we do supply with incredibly fast lead times, and we work with a range of trade partners that may be able to help. Get in touch with our professional team for more information if you’re in need of a sash window restoration or replacement. PVC sash windows can last much longer than timber, making them an excellent replacement for old damaged homes.

How Do Sash Windows Work?

A sash window consists of two sashes that slide up and down. Often these two sashes will be equal in size, although you do have the option of specifying a custom split. On advanced sash windows such as ours, both the top and bottom sash will come with a slide and tilt facility. For the sashes to slide up without immediately sliding back down, each sash is comprised with a mechanism used to counter-balance the sash eliminating the need for sash weights, sash cords and pulleys found on traditional sash windows. The balances are concealed in the two chambers found on each side of the sash window. Here at Quickslide we use a constant force balance system as well as a spring balance system.

how To Clean Sash Windows?

When cleaning your sash or casement windows, you should not use any harsh products such as bleach or nail varnish to get any marks off, as it could scratch or warp the frames. Quickslide recommends using a clean cloth together with a non-coarse neutral solution, such as washing up liquid mixed with hot water. This will get the marks off and prevent any damage to your windows. The sash double glazing incorporated on all of our vertical sliders can also help reduce condensation, leading to a crystal clear view that doesn’t create issues in the winter.

Why uPVC window sashes instead of timber sash windows?

Wooden sash windows may have the heritage appearance, but they won’t last as long as double glaze sash windows made from robust modern uPVC. Plus, they can require much more maintenance to prevent them from warping, splintering, or having their colours fade.

Sash windows timber can bend after continuously being opened and closed, or from intensive weather. A wooden sash window can be half the lifespan of the Legacy sash double glazing windows from Quickslide. If you have customers truly in need of timber sliding sash windows. then see our accurate woodgrain foils – they could be the perfect solution. All our foils are designed to match the appearance of wood sash windows, providing our windows with gorgeous classic aesthetics. Enhance properties today with modern plastic sash windows, and choose Quickslide to maintain that authentic heritage look.

I have used Quickslide a few times for their sliding sash windows. The service from the staff is quick and professional, they are always there to give advice and offer help with any query. The quality of the windows is excellent. They are a pleasure to install and have not had any problems with them since. They are easy to operate and keep the rooms warm and draught free in the winter months. All in all, I would not hesitate to recommend Quickslide and their products, one of, if not the best company I have dealt with.

Phil Wooller

Been using Quickslide for a few years now. Really happy with their product and customer service. Staff are always friendly and willing to help. An all round really nice company to deal with.

Swift Windows

Our customers, particularly in the traditional buildings around York, mainly request the 'Legacy' Sliding Sash windows. These windows look fabulous; so authentic that many people are shocked to discover they are not made of wood. The windows are a great advert and more often than not, having installed Quickslide 'Legacy' windows in a property, the neighbours will approach us for quotes for their own houses.

Juliet Waters

Our experience from first encounter at the Quickslide Sales office in Brighouse to the completion of 14 fantastic new sash windows, was absolutely first class. The company was a pleasure to work with throughout the process. Knowledgeable and extremely pleasant and capable staff at all points along the way.

Kevin Galloway

We ordered over 30 mainly sliding sash windows in 2 batches for a project. The quality of the windows is excellent and great value for money. The lead times for both orders were accurate. The communication prior to each delivery and from their own drivers were faultless.
