Costs & Investment
Are Aluminium Windows Worth It?

They're worth it if you value slim frames, large glass areas and low maintenance — typically on extensions, contemporary homes and larger projects. On a small cottage replacement where appearance can be matched by flush uPVC, the extra cost may be harder to justify.
