Shocking quality AVOID We paid for triple glazed, energy efficient windows. Once installed we commented to the installer how we could still hear outside noises, whereas our other triple glazed windows (not Anglian) we couldn’t and also it felt draughty. Installer stated that it was due to the vents which were now a mandatory requirement. A few weeks later, still unhappy, my husband looked past the vents and found that the windows didn’t fit properly as there were big gaps at the top join! We firmly believe the installer knew this when he fitted them and tried to cover it up. Appalling. Wouldn’t recommend them to my worst enemy.
