Are you looking for high-quality windows for a commercial installation? Then you'll have noticed one thing straight away. The world of windows is much more varied than you might first have thought.
Today's suppliers offer whole catalogues of different types of windows. The glass used. The material used for the frame. The energy efficiency rating. The decorative features.
In our opinion, this range of options is a horn of plenty – one that benefits project managers, window installers and building users alike.


But we're not going to deny there's a downside. That downside is a little something consumer behaviourists call "analysis paralysis".
With such a range of options available, how can you know which to choose? Why, for instance, should you use uPVC windows rather than timber, metal or some other material?
It's not long before a quick flick through a window catalogue can leave you howling at the moon.


That's why we've put together this buyer's guide to commercial uPVC windows. We cover:

  • The kinds of commercial uPVC windows available
  • The benefits of uPVC as a material
  • How we can help you get the materials you need

We hope it helps you in your next commercial project.


What is a uPVC window?

uPVC stands for "unplasticised polyvinyl chloride". It's a rigid and durable type of plastic used for window frames, doors and guttering.
The word "unplasticised" is important. Standard PVC is vulnerable to weathering, rot and corrosion. The lack of plasticisers in uPVC, however, makes it a highly durable, insulating and low-maintenance alternative to wood.
These qualities are ideal for window frames. They can be manufactured in a range of colours and finishes, they last for years and they keep the heat in and draughts out. At a time when the cost of living continues to soar, this can be a great benefit to homeowners and business owners alike.



Examples of commercial uPVC windows

The phrase "uPVC window" refers to the material used for the frames. Within this category fall several different types of windows. In commercial installations, these include casement windows, tilt-and-turn windows, fixed or picture windows and high-security windows.
Large-scale casement windows are designed to cover a wide area of a building's facade. They provide a high level of ventilation  and insulation without obstructing the view. This can give a commercial building a wide, open aspect.


Tilt-and-turn windows also offer good ventilation, but they open differently from casement windows. Their inward-opening mechanism makes them easy to clean in high-rise buildings.
Fixed windows, sometimes known as picture windows, are large, fixed panes of glass often used for storefronts or other large facades. They maximise a building's views and can give commercial settings a modern aesthetic.


Whichever style you choose, high-quality uPVC windows now provide exceptional security thanks to their robust, multi-point locking systems, toughened glass and reinforced frames. This enhanced security is indispensable, no matter how big or small your business.
And like all modern windows, uPVC frames come in a range of styles and finishes. This helps your windows blend into the building as a whole and can even reflect your brand identity.


Why use uPVC windows in commercial applications?

At this point, you may be wondering why uPVC is the best material for commercial applications. Why not use metal, wood or composite materials?
In our view, there are four compelling reasons to choose uPVC. These are durability, energy efficiency, low maintenance requirements and cost-effectiveness.


1. Durability

uPVC is built to withstand harsh weather conditions. This is one reason we're confident enough to offer a 10-year warranty. It's also why uPVC is a popular choice of material for commercial buildings that have to put up with the Great British weather.



2. Energy efficiency

uPVC frames offer excellent insulation. They create a tight seal that keeps heat out in summer and in during the winter months. This means building managers are less likely to reach for the thermostat and the finance team is less likely to wince at your company's energy bills.

3. Low maintenance requirements

uPVC windows are easy to clean and don't require painting. All you need is a sponge or cloth and a gentle detergent solution. And because they're unpainted, they never need to be repainted and they never end up looking old and tired. This makes them a low-maintenance option in any commercial setting.


4. Cost-effectiveness

Finally, uPVC is a cost-effective solution, especially compared to metal. If you work with the right suppliers and installers, you're likely to get more bang for your buck.


What to look for in a uPVC window installer

It's a hard fact of life: materials are only as good as their providers.
Yes, you can invest in the best materials on the market. But if you work with a subpar supplier, you're likely to be faced with logistical complexities, delays and budget-eating downtime.
