Glass

The majority of the windows and doors we supply are double glazed, in accordance with the New Zealand Building Code’s H1 Energy Efficiency clause.

As with choosing your aluminium joinery colour, we always recommend looking at the various glass options in-person so you can get a better feel for how your windows will look in-situ. No matter which glazing options you select for your new joinery – tinted or clear, argon-filled, Low E – all of our ALTHERM^® windows are supplied with safety glass that complies with New Zealand Building Code Glazing Standard NZS 4223.
