Edinburgh Sash Windows

Sash windows are an elegant window style that is known for their ease of use and compact nature. Instead of swinging outward, sash and casement windows slide upwards, or downwards, opening an entire pane to allow for fresh ventilation. Perfect for homes where space is at a premium, our double-glazing units serve as fantastic replacement windows, giving you a window that will keep your home warm, and provide robust levels of security.

Sash and Casement Windows

Sash windows have remained at the same level of demand throughout the years in Edinburgh, being cemented as a historical and integral part of the architecture. That being said, double-glazing Edinburgh products have been soaring in popularity, and the traditional single-glazing windows that previously made up the majority of sash products quickly became outdated.

The UK is moving in the direction of reducing heat loss from the home through energy efficiency measures, and Pro Glaze Group’s Edinburgh double-glazing products reflect that perfectly. You can expect from us the following:

  • Upper sash
  • Lower sash
  • Sash cords
  • Warm edge spacer bars
  • Optional glazing products (bars, etc)


Our new double-glazed windows have all the charm of traditional sash windows, with the added boost of modern craftsmanship designed for the long term, lowering your carbon footprint and energy bills both.

Why upgrade with Pro Glaze Group?

Pro Glaze Group’s double or triple-glazed windows will make a huge difference to your home in the following ways:

  • Lower energy bills – Double-glazed windows block at least 50% of what would otherwise be lost heat, with triple-glazed windows blocking an additional 20 – 30 per cent.
  • Noise reduction – Double glazing windows in Edinburgh block around 70% of all external noise. The capital of Scotland is a busy place despite its compact nature, making this less of a luxury, and more of an essential feature for your peace of mind.
  • Reduced condensation – Our advanced double-glazed windows cut condensation down by nearly 3/4s, making your home cleaner, and healthier, by reducing the opportunity for microbial allergens affecting you.
  • Home security – Our double-glazing windows and doors come with maximum security features, with multi-point locking systems and thick, hardened Edinburgh glass.
  • Property value – Homes installed with double-glazed units benefit from an increase in property value, due to thermal efficiency and other quality-of-life features.


Aside from all of this, Pro Glaze Group offers the most bespoke products on the market. As the leading Scottish home improvement company on the market, we offer a full range of customisable window types, whether that be UPVC windows, bay windows, windows with tint or colour, and more.

Having your windows replaced with our double-glazing Edinburgh grade range may be an exciting prospect, but we understand it’s also common to want to know how long, and how much, the process is going to set you back. Our company prides itself not only on its speed but also our quality of installation service, complete with minimal disruption to your home.

How long our service will take depends entirely on how much work we have to do in your home. For a single sash window, you can expect between 2 to 3 hours approximately to complete. If this sounds like long for a window, understand that the structure of sash and casement windows is more complicated than your average window installation. This is also why you want to hire professionals, as even the slightest misalignment can mean the breaking down of your window.

Regardless of how many windows you require, you can always trust our service to give legitimate, accurate quotes, and a timeframe that we do our best to adhere to. Book a free survey today, and we’ll give you accurate figures that align with your plans as closely as possible.

Edinburgh’s New Town is a UNESCO world heritage site, and a conservation area, meaning they are subject to planning restrictions. The following are guidelines to follow for compliance:

  • Like-for-like replacement – The new windows must closely match the original design, materials and proportions of the old windows. This typically means timber-framed, vertically sliding sash designs.
  • Material requirements – Original materials such as timber are often required, but sometimes a pass can be given for some materials that achieve the same look, but aren’t of the same makeup.
  • Glazing specifications – Double glazing is sometimes permitted, but these windows must retain their traditional appearance. In cases where double glazing is not permitted, you may still be able to use secondary glazing.
  • Approval needed – Replacing windows in any listed area requires planning permission and listed building consent from the local authority.

Yes, our windows come in various materials that radically change the look and benefits of your Edinburgh windows in general.

  • Aluminium Sash Windows – Aluminium gives a sleek and modern design coupled with high thermal insulation.
  • Tilt and turn windows – Tilt and turn windows provide similar ventilation to sash windows, opening in two directions whilst opening and closing tightly for enhanced energy efficiency.
  • Vertical sliding windows – Modern vertical sliding windows mimic the sash window’s opening mechanism.
