Heat Efficiency of Double Glazed Doors
UPVC Door Energy Ratings
For those homeowners who are going to fit double glazed front doors, one of the first things to check is the energy efficiency rating of the product you are considering by looking at the WER (Window & Door Energy Rating).
Window Energy Ratings (WER’s) are issued by the British Fenestration Rating Council and grade the whole window and frame together as one complete unit by categorising them alphabetically, with an A rating being the top – the rating is also based on ‘traffic lights’ so green is good, red is ‘danger!’
However, more and more window systems are exceeding the requirements of the A rating and so there are many uPVC Doors that can get A+ or even A ++ ratings for energy efficiency.
