We manufacture Altus Aluminium's wide range of market leading residential and commercial windows and doors. We specialise in all types of new residential and commercial windows and doors, residential renovations and conservatory design and installation.

Rylock Otago has five main product lines that we manufacture and / or market. Our primary activity is the manufacture and sale of Rylock Aluminium Joinery. Sitting alondside this is our "Dualglaze" double glazing, "Windsor" garage doors, "Unex" balustrades and "Phantom and Amplimesh Insect Screens”.

Through our highly experienced and customer focussed staff, Rylock Otago is committed to working with our customers to ensure that we find the right solution for their needs. No job is too big or small for our team who will work with customers to help cut through the jargon and technical details that seem so prevalent in the aluminium joinery industry.
