Is Double Glazing Sustainable?

25 November 2021

Is double glazing sustainable? At Dempsey Dyer, we’ve been helping businesses and companies across the UK realise how much double glazing can help them. Double glazing makes windows, doors and even conservatories more durable, efficient and comfortable for your customers. As a result, it’s a dramatic improvement for most homes and commercial buildings.

However, is it a sustainable one? With energy bills rising more than ever and the climate situation feeling more precipitous, now is the time to make sustainable decisions for your company. Fortunately, modern double glazing is already paving the way for homes and businesses to become more eco friendly. Today, you can now offer uPVC, aluminium and timber windows and doors that are recyclable, sustainably sourced, and efficient enough to reduce energy usage.

With Dempsey Dyer, you can invest in double glazing that is sustainable for your business. We make sure our full range of double glazing products won’t harm the environment, and they can help your customers make savings for their homes as well. Because of this, anybody looking to make their home more sustainable will look to you. And, with us as your trade supplier, you can get fast turnaround times and the capability of custom orders to help you provide the answers.

Is Double Glazing Efficient?

One of the main questions about double glazing is how efficient it is. With Dempsey Dyer, you can invest in windows and doors for your business that can dramatically improve the insulation of homes and commercial buildings. Our designs can come with uPVC, aluminium or timber profiles, which are resilient, durable and air and water-tight. Because of this, there will be no room at all for cold air to get through, helping your customers keep warm throughout the year.

Double glazing uses two panes of glass, as well, providing more insulation. The two panes of glass can trap heat inside while keeping cold air outside, meaning energy escapes less as well. As a result, double glazing can improve the effectiveness of the energy your customers will use, meaning they’ll be able to stay warm while relying less on their central heating. Because of this, they’ll reduce their energy bills and their carbon footprint, and they’ll have your company to thank.

Is Double Glazing Sustainable Long-Term?

Double glazing is also a long-term, sustainable investment for your customers. When they choose one of our windows and doors through your business, they’ll be able to get a design that will stand the test of time. Our double glazing products are highly durable, and they’re fully weatherproof to make sure the profiles won’t crack, twist or warp out of shape. As a result, some of our windows and doors can perform for decades to come, and they don’t need regular maintenance.

Even when they wear down, our double glazing remains sustainable. It’s because Dempsey Dyer’s range of windows and doors is all fully recyclable, and it’s sustainably sourced as well. Because of this, none of the products you order from us will ever end up in a landfill, giving your eco-conscious customers peace of mind. And, for your business, you can reduce your carbon footprint by needing to order fewer windows and doors and choosing sustainable options for your company.

Double Glazing with Sustainable Materials


We only install double glazing that has sustainable materials in its design. Because of this, we’ve made sure that uPVC is a key part of our range. uPVC windows and doors are more versatile than old steel or timber designs, as the material is fully weatherproof and can perform capably in even the worst conditions. Not only that, uPVC windows and doors are more thermally efficient than those old designs, helping your customers save on energy bills and decrease their carbon footprint.


Aluminium double glazing is just as sustainable as our uPVC double glazing range. With aluminium profiles, the double glazing you can offer to your customers will be strong and resilient, making it more secure and able to last longer. Your customers won’t have to maintain aluminium windows and doors regularly, and they can still last for nearly half a century. The profiles won’t warp, crack or even discolour, meaning they won’t need replacing or repairs to reduce the materials used and emissions created.


At Dempsey Dyer, we can also supply engineered timber double glazing to your business that is sustainable. It’s because we use Accoya wood across our range, a specialised timber product that is manufactured sustainably. We put the wood through a process that strengthens it and makes it more resistant to wind and rain, but the process produces no harmful toxins. And, because our timber windows and doors are fully recyclable, you can let your customers know it will never end up in a landfill.
