Investing in New Windows
February 7, 2011
When it comes to replacement windows cheaper isn't always better.
As the old adage goes, cheap isn't always best and replacement windows is certainly a case in point. I am sure there are many fantastic offers out there but with all things, don't be taken in by what may seem an offer too good to be true - sometimes it isn't. Poor fitted windows or windows that offer lower thermal performance levels will cost you more in heating bills and therefore, you have defeated one of the main objectives of having them replaced.
So, what do I need to look out for? Many new windows will come with energy ratings - a bit like the ones you find on new white goods such as washing machines and fridges. Also, if you choose windows with Low Emissivity glass, this will help maintain a more consistent temperature throughout the year as it will prevent excessive solar gain in the summer by reflecting the heat outside, while the coating on the inside of the glass keeps the warmth inside during cold spells.
In order to meet Part L of the Building Regulations, all replacement windows will have to meet this rigorous standard. You should therefore choose windows with a Window Energy Rating (WER) of band C or above, or a combined U value of 1/6W/m2K. This science doesn't stop here I am afraid. You need to ensure that it is the whole window U value that is quoted and not simply the centre pane value, as this can be a misleading value for the full unit.
For houses that are Listed in a Conservation Area or where Permitted Development Rights have been removed, our advice is to consult with your local authority Historic Buildings Officer before considering replacing windows. The reason for this is that Upvc frames may not necessarily be the most appropriate material to be employed on a historically sensitive property.
