Double Glazing Existing Homes in the Waikato

Hamilton and its surrounding townships of Cambridge, Matamata, Morrinsville and Te Awamutu boast a broad range of New Zealand house styles.  From late 1800s Villas and early 1900s Bungalows, with their traditional colonial style windows, through to modern era homes with large aluminium joinery windows and doors, The Double Glazing Company solutions cover the spectrum.

Where home owners are looking to retain the character and wider benefits of timber, retrofit double glazing into the existing timber-framed windows, together with options like high-performance draught seals are the answer. 

These beautiful character homes can thus have high performing windows that both respect their heritage and provide comfort and enjoyment in 2021. 


Where replacement double glazed windows are sought, whether for moving away from deteriorated timber joinery or flimsy 1960s-1970s aluminium-frame windows, The Double Glazing Company solution range includes thermally enhanced replacement joinery with all the modern-day functionality and low maintenance benefits.

Where homes owners have existing aluminium joinery that is robust, The Double Glazing Company solution of retrofit double glazing into the existing frames provides the opportunity to upgrade the insulation and make changes  to modernise the look and feel of the home.
