Now that the weather is warmer, neighbours are out in their gardens with their kids and pets, enjoying the sunshine. My secondary glazing was installed in late February 2023, but it's only now that I have had an opportunity to test how well the secondary glazing dampens excess outside noise. Unfortunately, the product does not do what Anglian promised. I can clearly hear every word of normal conversations that my neighbours are having. The product is rubbish and based on all of the other poor reviews about products from Anglian, is anyone interested in joining a class action law suit against this company? That may be the only way to hold them to account.
