The Benefits of Double Glazing

Insulated glazing, also know as double glazing to the layman, oh where to begin? Well let’s start with the definition shall we?
The Double Glazing term relates from double to tripled paned glass windows separated by an air or other gas filled space to reduce heat transfer. Pretty groovy, huh? Insulated Glass Units (IGUs) are manufactured with laminated or tempered glass that varies in thickness from 3 mm to 10 mm or sometimes even more in special applications. This is a very important feature to consider for your home because nearly 25% of the energy used to heat and cool your home is lost through ineffective single glazed windows. Let’s face it, any improvement that results in a smaller carbon footprint, reduces drafts and cold spots, and conserves the air temperature of your home, gets the thumbs up in my book.
We found an excellent UK based company called Zenith Windows who explained to us how their double glazed windows help reduce energy bills;
Typically, the glass panes are separated by a spacer. A spacer is the piece that separates the two panes of glass, and seals the gas space between them. Historically, spacers were made primarily of metal, which manufacturers believed provided more durability.
We recently had a home energy survey conducted and our old windows show plenty of hot spots, check out this thermal camera image below;

The bottom line is, if you are thinking of replacing your old windows, make sure you pick an energy efficient double glazed window and then you can relax and watch the energy savings pile up!
Thanks for reading, if you would like to share your success stories from changing to double glazed windows we would love to hear from you, just leave a comment…
Double glazing windows are the best option. They are energy efficient and give great security. They also keep the noise pollution away.
Is there really an added benefit to triple-glaze? Or double-glazing is enough?
