Windows to suit your style

We offer a range of sash window styles to match your old windows, and to maintain the style of your home.
Sliding Sash Windows Image 1

Our sliding sash windows work in the same way as a traditional wooden box sash window, with both top and bottom sashes sliding up and down.

Convenient and simple to operate, the two sliding sashes within an outer frame work independantly of each other on a balanced load mechanism, designed to hold the sash at any height you desire.

We can replace bay windows, as well as arched and swept head windows with PVC-U sliding sash windows.

Our PVC-U sash windows are incredibly low maintenance, requiring only a quick wipe down with a damp cloth to keep them looking as good as new.

The window sashes feature an inward opening tilt facility to allow easy and safe cleaning of the outside frame and glass from inside your home. This is particularly useful for second storey windows or windows positioned in a hard to reach place, such as above a conservatory.

Assessing Visual Quality

The standard method to assess the Visual Quality of Low-e glass is to stand perpendicular to the glass at 3 meters away. Do this in natural daylight but not direct sunlight as well as ensuring there is no visible moisture of the glass. If your vision is not impeded under this situation, then your windows are of good visual quality.

Windows Plus Low-e glass can allow you to stand at 2 meters away instead of 3 meters. This means that Windows Plus Low-e glass is much better than industry standards.

How can I make my conservatory warm?

There are many different ways to achieve this. Most likely, you will end up doing all of them.

  1. Double glazing your windows. Windows transfer a lot of heat from inside your home to outside. Double or triple glazing your windows is a quick way to ensure that heat stays within your home. 
  2. Replacing glass conservatory roofs. While traditional conservatory roofs look beautiful they have a myriad of problems. They let out too much heat when it's cold outside. A thermally efficient warm roof can make sure your conservatory remains warm in the winter.
  3. Update your doors. Depending on the type of door you are using for your conservatory, you may be losing out. Wear and tear can accumulate meaning your once energy-efficient door are no longer good enough. Get your door inspected and if needed, repaired to keep saving on your heating bills.
  4. Convert your conservatory to a sunroom. This is a big change as it no longer is a conservatory but an extra room in your home. With both heating and cooling mechanisms, you will really feel the benefit.
  5. Having Double or Triple glazed windows. Windows are one of the main reasons Conservatories lose heat so quickly. By insulating the Windows, you will see a big difference.

What is the difference between Double glazing and Triple glazing?

Double Glazing is the process of using two panes of glass within a frame while Triple Glazing is using three panes.

Between these panes of glass is a layer of Argon gas. Argon gas insulates the window resulting in a higher energy-efficiency.

With three panes of glass against two, Triple Glazing is more energy-efficient than Double Glazing.

What is PVCu?

uPVC (also known as PVCu) stands for Un-plasticised Poly Vinyl Chloride. This is the fancy way of saying a "Plastic based product". PVC is a popular material to be used in building and is a very flexible and superb material to be used.

When you see the "U", this means that when the plastic hasn't been softened during the creation process resulting in a much stronger material than standard PVCs.

Is there a guarantee?


All our products come with guarantees. Generally, these guarantees will be between 10 - 15 years. Get in touch to ask about our guarantees.

How often should I clean my windows?

There are many factors to include when thinking about keeping your windows clean. A rule of thumb is to get your windows cleaned twice a year. If you live in a more open area and are exposed to harsher elements (sea air etc) then you should clean your windows three times a year to prevent any dirt and grime causing future issues.
