Replacement Windows & Doors

Replace your old timber or aluminium joinery with our new thermally enhanced windows and doors, including high performance double glazing.

If your windows need replacing, our replacement window solution is a great option for your home. Designed here in New Zealand for our climate, our thermally enhanced windows and doors provide superior insulating performance. This means you retain more heat inside when its cold outside.

How does the process work?

Installation is a straightforward process. We will remove your existing timber or aluminium windows and doors (frames and glass), and replace them with our thermally enhanced replacement window and door joinery – ThermaL 4.0™.

What is ThermaL 4.0?

The Double Glazing Company has partnered with Fairview Systems, NZ leaders in window & door solutions, to develop ThermaL 4.0™ – the next generation of thermally enhanced aluminium joinery.

Advancing from previous generations of aluminium windows and doors in New Zealand, the ThermaL 4.0™ design incorporates thermal performance enhancements together with manufacturing efficiencies to give you high performing windows and doors at a competitive price. When combined with our high performance SuperTherm™ glass it will create a warmer, dryer home in winter and a cooler home on those hot summer days.

On completion, you will have windows that perform at the top end of NZ’s WEERS rating system.
