You’ll be all “WHITE” with A-rated Windows

Over the last couple of weeks I’ve been writing about the different energy efficiency improvements in the home. Most recent Blog posts have focused on Solar Thermal and Photo Voltaic technology and how investing in these can not only make your home more efficient but also possibly provide an additional income.

However not everyone will be in the position to consider this type of home improvement. Reasons for this could vary from either a financial or practical perspective like living in a flat. Homeowners will still look towards a more improving their homes by replacing your windows for a more efficient design.

I have been told several times recently that homes that have or desire an alternative colour window to white struggle to get the ultimate A-rated efficient window in other colours. The question is why can’t we supply an A rated Mahogany or Rosewood uPVC window?

It's White

Taking the Anglian Mahogany, Rosewood and Golden Oak windows first. Due to their dark colour these window frames will absorb, unlike white, far more heat and being a thermal plastic are liable to expand to a greater extent. To combat this Anglian dark woodgrain windows are always fully reinforced. This additional steel reinforcement reduces the thermal performance of the frames. As such even if we were to use low iron glass in the out pane we would be unable to achieve an A rating.

As you can see from the above it is a balancing act to ensure that our windows meet all the stringent performance criteria that we expect, whilst at the same time achieve a thermal performance.

Whilst the majority of window companies are able to offer A rated white PVC windows, it is far more difficult to achieve an A rated dark woodgrain finished window that has the same performance characteristics. So the questions to ask is if you find a company that actually has an A rated dark woodgrain Window Energy Rating or do they possess one for white only? If they do, have they compromised on the performance of the window (i.e. not fully reinforced) to achieve this standard?
