Double glazing installers in Auckland
The largest market and the most competitive — almost every national double glazing brand has an Auckland depot, and most retrofit IGU specialists work the metro and the Hibiscus Coast. Mild winters mean the warmth case is weaker than the South Island, but condensation is the bigger problem in unrenovated post-war housing.
Condensation, not heat loss, is the headline complaint. Warm-edge spacers and good ventilation matter more than thicker IGUs.
