retroGLAZE® suppliers.

Retrofitting or replacing your windows and doors can have you feeling uncertain.  How do you know you can trust that the product used is to a high standard?

Double glazing.

Our double glazing manufacturers here in New Zealand provide the highest-performing double glazing units, including superior thermal spacers. These suppliers are current members of IGUMA (“Insulating Glass Unit Manufacturers Association, New Zealand), meeting BRANZ testing standards.

Profiles: Timber.

retroGLAZE® has developed a suite of timber profiles specifically designed for retrofitting double glazing into existing timber frames. Our supplier, Tunnicliffe Timber, uses wood grown sustainably here in New Zealand and these timber profiles meet export-grade standards.

Profiles: Aluminium.

retroGLAZE® has developed a suite of aluminium profiles unique for retrofitting double glazing into aluminium frames. These aluminium profiles are exclusive to retroGLAZE® and the aluminium is extruded here in New Zealand by our supply partner, Fairview Systems. The aluminium “billet” that is used in the extrusion process is predominantly supplied from Tiwai in the South Island.
