Double glazing installers in Otago

Dunedin's older villas and Queenstown's holiday-home builds are two very different markets. Dunedin retrofit work is dominated by a few long-established installers; Queenstown new-build glazing is its own premium scene with H1-Climate-Zone-6 spec requirements.

Climate Zone 6 H1 requirements are stricter — for new builds you'll typically need argon fill plus low-E, sometimes triple-glazed for north elevations.
