What is Insulated Glazing or IGU?

Benefits of Insulated Glazing for Energy-Efficient Homes in Leicester

Benefits of thermal glass unit

If you’re in the process of building or renovating your Leicestershire home, you’ve likely come across the term “insulated glazing.” But what exactly is insulated glazing, and why is it becoming a popular choice among homeowners? 

In this article, we’ll explore the world of insulated glazing, discussing its benefits, how it works, and why it’s an excellent investment for energy-efficient homes.

What is Insulated Glazing?

Insulated glazing involves the use of two or more glass panes separated by a gap filled with air or gas. This gap acts as a barrier that significantly reduces heat transfer between the interior and exterior of a building.

If you weren’t sure, insulated glazing (IG) is the technical term for ‘double glazing’ and ‘triple glazing’.

How Does Insulated Glazing Work?

The secret behind the efficiency of thermal glazing lies in its construction. The gap between the glass panes acts as an insulator, preventing heat from escaping during the colder months and blocking unwanted heat from entering during warmer months. 

Additionally, some thermal glazing units contain a special gas, such as argon or krypton, between the panes. These gases have a higher density than air, further improving the insulation properties of the windows.

How Long Does Insulated Glass Last?

Insulated glass is designed to be durable and long-lasting. On average, well-maintained insulated glass windows can last around 20 to 25 years or even longer.

However, the lifespan can vary depending on several factors such as the quality of the materials used, the installation process, the local climate, and how well the windows are maintained over time.

Regular maintenance, including cleaning the glass surfaces, inspecting and maintaining the seals, and addressing any issues promptly, can significantly extend the lifespan of insulated glass windows. Proper care helps prevent moisture buildup between the panes, which can lead to condensation and reduced insulation efficiency.

The Benefits of Insulated Glazing

Improved Energy Efficiency

One of the primary reasons homeowners opt for insulated glazing is its remarkable energy-saving capabilities, especially as over 25% of heat escapes through windows.

By minimising heat transfer, insulated glazing helps maintain a consistent indoor temperature, reducing the need for constant heating or cooling. This, in turn, leads to lower energy bills and a reduced carbon footprint.

Enhanced Comfort

Thanks to efficient temperature regulation, rooms with insulated glazing stay more comfortable throughout the year. Say goodbye to cold drafts near windows during winter or the unbearable heat seeping in during summer.

Noise Reduction

Insulated glazing doesn’t just stop at temperature control—it also provides excellent noise reduction. The multiple layers of glass and the insulating gap work together to dampen external noises, creating a quieter and more peaceful living environment.

Condensation Control

Traditional single-pane windows are more prone to condensation buildup, which can lead to mould and mildew issues. Insulated glazing significantly reduces condensation by maintaining a balanced temperature on the inner glass pane, ensuring a healthier indoor environment.

Increased Property Value

Investing in energy-efficient features like insulated glazing can boost your property’s value. Potential buyers are increasingly drawn to homes that are equipped with sustainable and cost-effective solutions.

Installation Process

Choosing the Right Insulated Glazing

Selecting the appropriate type of insulated glazing depends on factors like climate, budget, and aesthetic preferences. Consult with experts to determine the best fit for your home.

Professional Installation

While some experienced DIY enthusiasts might consider installing insulated glazing themselves, it’s recommended to hire professionals. Proper installation ensures the windows perform optimally, seals are airtight and reduces double glazing failure.

Maintaining Insulated Glazing

Cleaning Tips

Maintaining insulated glazing is relatively simple. Regularly clean the glass surfaces with a mild glass cleaner and a soft cloth to keep them looking clear and attractive.

Preventing Damage

Avoid using abrasive materials or sharp tools that could scratch or damage the glass. Inspect the seals for signs of wear and tear and address any issues promptly to maintain the insulating properties.

Is Insulated Glazing Worth It?

Long-Term Savings

While the initial cost of installing insulated glazing might be higher compared to traditional windows, the long-term savings on energy bills make it a financially prudent choice. The energy efficiency translates into reduced heating and cooling expenses.

Professional, skilled, great communication from the on-site team - honestly, the best workmen I’ve ever had. They left the place tidy and neat. Thanks guys! They did a great job on a dreary, winter’s day with a smile. I love the new porch, which was a decent price. Honestly though, the sales guy Tom and the crew of Cal, Jake and Aaron were great. After having had a bad experience before with a different company, I’ll be using Phair Windows to replace my windows in the near future as well.
