Hi,
Have received 2 very differing quotes for PVC double glazing (10 windows, 1 french doors, 1 porch door and 1 back door).
Quote 1 from Supplier X
Whole Window U-Value 1.28
Price: €9140
Quote 2 from Supplier Y
Whole Window U-Value 1.5
Price: €5200
Supplier 1 said their windows have spacer bars and are NSAI certified. Supplier 2 are certified but not NSAI, British standard of some description.
I'm going to quiz supplier 2 on their cheap quote.
I want to make sure that we get the best value window, not necessarily the cheapest.
Is it plausible that the windows from Supplier 2 are genuine and how should I prove that they're good.
