What does it actually mean to clients?

The scheme is designed to distinguish between the elite [1st] Window Partner and other very much smaller regional Internorm “Distributors” who by definition do not meet these strict criteria. By engaging with AT-Eco Windows you are working with one the largest and most successful UK Internorm providers.
