Double Glazed Windows | Health Protection

Reduce Condensation

When we cook, bathe or even breathe, we increase the water vapour levels in our homes.  As saturated air contacts a cold surface, like a window, condensation forms. This dampness promotes bacterial growth and mould and can compound respiratory problems such as asthma.

Double glazed windows are typically 3-4°C warmer than those with metal spacer bars; reducing condensation by up to 80%

Double Glazed Windows | uPVC or Aluminium 

Maintenance Free Materials

Aluminium or uPVC double glazed windows, which one?

It really depends on what you are looking for with your double glazing. If you have a home with small windows then you might be better off looking at Aluminium. Aluminium tends to be stronger and therefore the windows can be made slimmer. This will give you more glass area compared with uPVC.

Whilst it’s true to say that Aluminium windows are slimmer and stronger. Investment and technology have resulted in multi-chamber uPVC double glazed windows which have similar strength.

Colour, Style, texture and choice used to be limiting factors but now, you can pretty much get whatever you’re looking for in both materials.

Maybe the one plus point for uPVC is the Timber Look, in my opinion, is more like the real thing.

What Are Double Glazed Windows2019-10-24T15:15:22+01:00

What Are Double Glazed Windows

Double glazed windows comprise two panes of glass which are separated by a gap. This gap in older style double glazed windows will usually be between 12mm and 16mm. In modern energy efficient new or replacement double glazing the gap will typically be 20mm.

The two panes of glass will typically be 4mm each giving an overall sealed unit size of 28mm. The sealed unit in modern double glazed windows systems will be filled with Argon gas. Because Argon gas is denser than air, adding it between the panes of glass improved the thermal efficiency of the window.

The sealed unit is then housed into a frame or a sash, these frames and sashes will be made from Timber, Aluminium or uPVC. The efficiency of the complete window system is assessed and to help chose the best window system for you BFRC (British Fenestration Rating Council) have created an energy rating scheme.

Double Glazed Windows are rated from A+ to G with G being at the bottom of the scale. The rating is calculated on the whole of the window which means that is it very important to ensure the quality of all components, not just the sealed unit.

Are Double Glazed Windows Worth It

Are double glazed windows worth it;  that’s a question which is asked a lot and whilst there is no simple answer, the answer is yes but for a lot of different reasons.

A Rated – Energy Efficient Windows

Testing has shown that new and replacement double glazing can reduce heat loss from your home by as much as 18%. This means that if you have single glazing or early-generation uPVC double glazed windows your bills will be much higher. At the same time, you may be experiencing increased noise from outside and added condensation from the performance of older window systems.

Fitting A Rated Energy efficient windows will save you money on energy bills which will help the environment whilst at the same time you will benefit from reduced condensation and noise.

So are double glazed windows worth it?

If we look at a home with single glazing and update that to A+ new or replacement double glazing windows then the potential savings are £797.04 per year. The example is based on a detached house with single glazing using electricity to heat the space. The calculations are done using the GGF official calculator.

The savings you achieve will vary depending on the current installation in your home and other energy measures which you adopt. Looking directly at the question are double glazed windows worth it would suggest yes, but not only financially.  Double glazed windows are worth it as a means to reduce CO2 emissions and as an opportunity to lower carbon use.
