There are a number of reasons why you might want to choose new doors and windows for your home, perhaps a change of style, a renovation project, and of course, to upgrade the energy efficiency of your home. Perhaps you simply just want to increase the natural light in your property, and did you know, this can actually reduce CO2 emissions? More on that further down! If your current glazing has been in your home for many years, you may notice your energy bills creep up as they become less efficient and end up costing you more money. 

Here are some of the signs your glazing may need replacing… 

Signs your glazing may need replacing 

  • Condensation between glass panes – this suggests that the seal that sits within the two panes of glass has failed, this means that the gas that sits in there has seeped out and been replaced with moist air. The windows ability to retain heat will therefore be affected. 
  • Feeling a draught – if your home is feeling draughty, this, again, could indicate that the seal has failed. Whilst some people may look to replace the seal, if it’s old glazing, this will not be a long-term solution and your best bet is to replace it with a new, high-performance glass. 
  • Items fading in the home – today, windows are much better equipped for offering protection against UV rays, unlike old glazing. If you find items such as your carpet and soft furnishings are fading, this can be a sign you need to upgrade your windows. 
  • Leaks – whilst small leaks may be fixable, if your windows are causing any significant leaks then it’s time to think about a replacement, otherwise, this could cause further costly damage. 
  • Difficulty opening and closing – another telltale sign of inefficient glazing is difficulty opening and closing, this can be particularly dangerous in the case of emergency and should be dealt with urgently. 

Are new doors and windows more energy efficient?

The answer is simply, yes, and for a number of reasons! As mentioned, old windows with broken seals, leaks, and gaps, can cause your home to feel draughty, in turn, causing you to crank that thermostat up and pump warm air through the house. This is not ideal for either your bank balance, your health, or the planet. By replacing your existing glazing you can upgrade to a high-performance alternative, and these days, there are many more options available even down to the glass you choose.

Can better glazing reduce CO2 emissions? 

We all enjoy plenty of natural light flooding into our home, and many self-build and renovation projects have ‘light’ as a key element to the overall design of the home with spaces revolving around oversized glazing. Getting the balance right is key, you don’t want to cause your home to overheat with too much glazing, but you also want to be able to enjoy a healthy home that’s filled with light. 

It’s a fact that properties that have low natural light tend to have a higher dependency on energy use. Turning on lights more frequently rather than letting the natural light shine in. Part L1A of Building Regs states “As a general guide, if the area of glazing is much less than 20% of the total floor area, some parts of the dwelling may experience poor levels of daylight, resulting in increased use of electric lighting.” By increasing the light in your home, you can in turn reduce your CO2 emissions, creating a more eco-friendly space. 

What is the best glass for large doors and windows? 

The good news is, here at Kloeber, all of our glass is high-performing and energy-efficient!

All of our products are also available with solar control glass which can help to reduce the G-value – a unit of measurement for UV rays of the sun penetrating through the glass from outside – whilst still giving the insulating values needed to keep the heat in. This glass is best suited to large doors or windows – such as our sliding doors – which are south facing.

On the contrary, if you have a smaller space but want to increase the energy and heat in your home then you may wish to consider our low-Iron glass which increases the solar gain. This lets in more of the sun’s energy and heat into your home so it is particularly good for north-facing properties. It is also good for saving on heating bills in the winter and increasing the overall energy rating of your doors and windows!

Another way you can increase light in your home and reduce CO2 emissions is to consider a slimline frame design. This will mean you have a higher ratio of glass, therefore letting in even more light! 

For a slim frame design check out ÜberSlide slimline sliding door -it boasts minimal 20mm sightlines for that ‘barely-there’ frame. 

Fixed glazing is another fantastic option for letting in light and can be used for those awkward spaces too…

Or why not consider our chic Heritage range, offering a contemporary design and slim sightlines.
