With sunshine one minute and howling with wind and rain the next, it’s no wonder we Brits have a fascination with windows. If you are wondering if double glazing is the best choice for your property, these key questions will hopefully give you an answer.

What is double glazing?

Double glazing uses two panes of glass separated by a layer or argon gas to keep your home more energy efficient and reduce sound. The argon gas is a poor heat conductor and therefore keeps warm air from escaping, while the second pane of glass acts as a barrier to noise.  Double glazing reduces the amount of condensation on the inside of your windows and because of the double layers of glass, your security is heightened as they are more difficult to break than single glazing.

What is triple glazing?

Triple glazing is effectively three panes of glass separated by argon gas. This means it has an extra layer of glass to insulate your home making it even more difficult for heat to escape from your home. 

As you would expect, triple glazing is more expensive than double glazing. If you have any rooms that are particularly cold or battle from external noise, you might consider just doing these with triple glazing. 

How will I know if my double glazing needs replacing?

69% of people buy double glazing to replace existing ones. If you are unsure whether yours need replacing, these signs will help you decide – 

  • They’re draughty
  • They are leaking / letting water in
  • They allow excess amounts of noise in 
  • They are difficult to open, close and close, or are sticking
  • They’re often covered in condensation (especially between panes)
  • The PVC is yellowing or timber is cracking 
  • There’s visible damage, particularly to the seals. 

How much money & energy can I save with double glazing? 

Saving energy saves money. Our windows have an A+14 energy rating. This means your home would retain an additional 14kWh per m² each year over a standard A+0 rated window. 

So what does this mean in actual savings? Compared to C rated windows, you would save enough energy each and every year to run a full-size A++ energy rated fridge freezer constantly and do a 2kg load of washing every other day for a year.

What frames can I use?

Energy-efficient double–glazed windows are available in a variety of frame materials, sizes and colours. uPVC frames are the most popular as they last a long time, are easy to care for and can be recycled. Wooden frames might have a lower environment impact but require maintenance and replacing more regularly. Aluminium frames are slim and long lasting and can also be recycled (though are more costly).  Choose your frame style: 

  • Casement Windows
  • French Casement Windows
  • Flush Sash Windows 
  • Tilt & Turn Windows 
  • Sash Horn Windows 
  • Sliding Sash Windows 
  • Bay and Bow Windows
