The answer is simple. If you choose quality aluminium joinery for your home or building project you are choosing a product that will do more than just add value. You are choosing something you will enjoy day after day and year after year. The smooth functioning of all your joinery will work quietly as you open windows, step outside or open up the bi-folds to catch a light summer breeze.

You won’t give it a thought — and that is just as it should be.

These are just some of the reasons that Altherm Aluminium Northland is the architects’ (and the good chippy’s) choice.

From homes to commercial and industrial premises, including public buildings such as schools, Altherm Aluminium Northland is the architects’ choice. For meeting the needs in window, door and joinery design, construction and installation through to innovation excellence, Altherm has led since the 1970s and still leads today.

We’re proud to call Northland home. For generations we have worked to provide Northlanders with the highest quality aluminium joinery products available in the market. We did then. We do today and we will tomorrow. So, please, take the time to browse our gallery showcasing just some of the ways in which we’ve used aluminium joinery to marvellous effect – practically and ascetically.
