What They are

For starters, it’s important to understand what commercial double glazing means and what it can do for your commercial space. Double glazing means you’re using two panes of glass on your window instead of a single layer. In addition, windows can be given an energy efficiency rating just like your appliances ranging from A-G which can also impact the price. Double glazing will continue to rise in popularity as these facts become more well-known and common knowledge. The frames of double glazing windows are made from aluminium, fibreglass, vinyl and wood and will vary in cost depending on the material and colour. They are known to have originated in Scotland in the 1870s and have evolved over time to what they are today.

Types & Styles

You should know that there are a wide variety of types of double glazing windows to choose from so it’s a wise idea to do your research in advance. It’s important that you take the time to search for what each one looks like so you can determine which will be best suited for your office space.

To name a few for consideration:

  • Casement windows
  • Single hung windows
  • Double hung windows
  • Awning windows
  • Fixed picture windows
  • Greenhouse windows
  • Round and octagon windows
  • Angle gable windows
  • Gliders
  • Bow and bay windows

They all differ in design and cost, and you’ll likely find that there are certain options that are more practical or fitting for your type of space and configuration. The upside is that there is a solution for you no matter what type of architecture you’re working with at your building.

Reduce Energy Costs

Most importantly, double glazed windows are going to save you money in the long-term. This is because of their excellent insulation capabilities and the fact that they keep you cool in the summer and warm in the winter months. Double glazing is a practical remedy to replacing single glazed windows which can allow for a lot of air to be exchanged and lost throughout the day.

Windows are given a thermal rating based on their ability to conserve energy, so be sure to check what this score is for the windows you’re considering installing so you know what to expect. With double glazing, you’ll be happy to see a decrease in energy costs when you go to pay your utility bill each month. Leaks, cracks or drafts on old or single paned windows will end up costing you in the long run so it’s in your best interest to address the issue as soon as possible. There’s no point in delaying this, so get the wheels in motion now.

Reduction of Noise

What’s great about commercial double glazing is that your office will be quieter and more pleasant of an environment to work in. These types of windows are particularly good at reducing the amount of noise that enters your building. This is especially important if you work on a busy street or have loud neighbours who bother you. The reason this holds true is because the air (or Argon gas) barrier between the two panes of glass acts as a natural sound barrier. Think of how much more productive you and your staff members will be when you choose to install double glazing in your space. You should be able to concentrate fully on tasks, and the noise and clatter from outside will be greatly reduced.

Property Value

Maybe one fact that you may not realise initially, is that as a business and property owner, double glazing is going to add value to your building. While it may not be the best choice if you’re remodelling a historic building, more times than not you’re going to be getting a return on your investment when making updates to your commercial space using double glazed windows. When you choose to sell in the future, you can point this out as a feature that’s going to stand out as an attractive upgrade to potential buyers. Overall, it’s a wise investment that’s likely to increase the resale value of your property and secure you a healthy return.

Finding A Qualified Contractor

What’s most important at this stage, is that you spend time finding and working with a qualified contractor for this type of project. You want someone who specialises in window installation and knows what they’re talking about when it comes to double glazing. You want the job done right the first time around and in a timely manner, so be picky about who you hire. Interview and meet with multiple contractors so you can compare their past work performance, personalities and pricing structure. Look for someone who not only have been working in the field for a long time but who have a solid reputation. Ask to look at pictures of previous window installation jobs and read reviews to help you narrow down your choices.

Installation Costs

Know that the cost of installing these windows isn’t a simple answer and will greatly depend on your exact location and the composition of your property. The rule of thumb is that you can expect to pay roughly 25% more for double glazing versus a single paned window. Remember to look at the big picture and that although you may be investing some extra money into your windows now, they’ll save you on energy costs down the road. It’s a wise idea to come up with a budget and then to shop around for various styles and designs based on what you want to spend and the structure of your building. Be prepared to negotiate the price so you’re getting the best value for your money, and consider buying at slower time periods such as toward the end of the year. Be willing to shop around for a good deal and only purchase the windows that are truly within your budget.

Office Building


Generally speaking, you can expect to have a 10-year manufacturer’s warranty on your double glazing. Consider also that your sub-contractor who installs your windows may have an additional warranty of their own that you should ask about prior to making your purchase. This should give you some peace of mind as you choose to invest your money into this project.


Another important benefit to point out is that double glazed windows also offer a safety feature. They’re thicker, and thus more robust, than single paned windows and will help to keep out intruders and burglars. You’re going to feel a lot more secure knowing that your windows are thick and can’t be damaged or broken into as easily. As a commercial property owner, you want to ensure that you and your workers are well protected from any external wrongdoers and feel safe and sound when coming to work each day. While cameras are nice to have they aren’t necessarily going to stop someone from trying to break your windows and steal your belongings.

Reduce Light Use

Furthermore, you may find yourselves turning on fewer lights while at the office when you choose to install double glazed windows at your property. This is because these types of windows help to allow the rays of sun to come shining into your space. You can opt to not use as much electricity lighting up your office and instead choose to open up your shades or blinds and let the sunshine in. This is a great feature for you based on the fact that you’re likely in, and using, your commercial building during the daytime.


These have been some of the most important factors to consider when installing double glazing at your commercial property. If you’re going to spend money on new windows, you may as well invest in one of the best protectors against noise and air seeping in and out. Take your time to shop around before deciding on which style you want to go for, because purchasing can be a large decision and investment. Whenever you’re feeling confused or need more information, then be sure to turn to the internet, local sales experts or contractors in your area who will be able to answer any further questions you may have regarding commercial double glazing.
