Energy Efficient Double Glazing: The Lowdown

energy efficient double glazing

Regardless of property size, poorly insulated homes can cause multiple problems for property owners. From a build-up of condensation, to uncomfortable, interior cold spots, energy efficient double glazing can help you tackle these challenges.

Over time, these issues can impact your levels of comfort and the structural integrity of your home.

For some, upgrading insulation may be the first port of call, providing an impressively airtight seal to block out the worst of the weather.

For others, upgrading existing glazing can offer similar benefits-and the opportunity to renovate the exterior to create a flawless first impression.

If you`re seeking something similar, and are desperate to drive down your bills, installing new double glazing is the perfect place to start.

With the above in mind, we give you the lowdown on energy efficiency ratings, how each glazing option compares, and the benefits you stand to gain by upgrading your existing windows...

Energy Efficiency Ratings, Explained

If you`re thinking of selling your property, or renting it out to tenants, an Energy Performance Certificate (EPC) is now a mandatory requirement. So what exactly is it?

Put simply, an EPC rating provides an overview of your home`s efficiency, and the associated costs involved for heating and maintaining your rooms.

The rating you receive for your home will depend on several factors, including:  

  • How much energy is used in the home
  • The quantity of carbon dioxide emissions.

An EPC lasts for 10 years on average. If your property is more than 10 years old, you will probably need a new audit before you can relocate.

Your energy efficiency rating should hover between A-C. Homes rated at the top of this scale are more economical to heat, making them attractive to prospective buyers.

If your rating is lower than expected, don`t worry! There`s plenty you can do to improve things without blowing your budget.

Your EPC will provide a few recommendations for increasing the overall rating, with an indication of the savings you can expect by implementing these suggestions.

Why is Energy Efficient Double Glazing Such a Big Deal?

Despite recent progress, homeowners are still making do with outdated, single-pane windows.

Over time, these windows become less effective, resulting in uncomfortable draughts and cold spots.

Unlike single-pane windows, uPVC double-glazed windows feature two panes of glass, enabling you to sandwich warm air between them and insulate your interior space.

The robust, resilient framework also eliminates potential gaps. Airtight chambers and seals prevent heat from escaping, helping you heat your home for less. 

How Does Energy Efficient Double Glazing Compare to Single Glazing?

Although it provides a simple barrier, single glazing is ineffective for retaining heat. Unlike double glazed windows, single glazed windows enable heat to pass through unhindered.

This interferes with the internal temperature and your ability to reduce your bills. So what makes double glazed windows superior to their single-glazed brethren?

The "air pocket sandwich" effect is the secret to their success. This nifty pocket of air creates the ultimate barricade, reducing the average rate of heat transfer.

Is Triple Glazing Worth the Extra Expense?

For properties in exposed areas of the country, the additional "buffer" of triple glazing is worth the additional expense.

Those living in noisy areas can also benefit from this product, with the extra layer of glass drowning out sounds from outside.

However, for the majority of homeowners, double glazing is usually sufficient, providing the protection you require for your home at a far more affordable price.

Modern uPVC windows tend to come in grades A-C as standard, ensuring you meet WER requirements for homeowners.

Are There any Other Measures I Can Take to Increase my Energy Efficiency Rating?

Absolutely! After upgrading your glazing, simple tweaks around your home can further support these efforts.

Homemade draught excluders are a cheap and effective fix-if you have scraps of fabric lying around your home, these are ideal for this purpose.

Other fixes, such as caulking and sealing, prevent warm air from escaping, enabling you to retain more heat. You could also consider replacing your existing boiler with a more energy-efficient model.

Generally speaking, combi-boilers are of the greenest boilers on the market. With combi-boilers, you simply heat the water as required, rather than all at once.

As this boiler type is also condensing, they reduce energy wastage, making them smart and efficient to use.
