This Wellington home presented a unique challenge with its combination of timber and aluminium joinery, along with greenhouse-style windows that required a careful, tailored approach. The homeowners wanted to upgrade their single-glazed windows to improve insulation and comfort while preserving the home’s character. With Wellington’s cool climate and strong winds, reducing heat loss and condensation was a key priority.

retroGLAZE® Retrofit Double Glazing provided a custom solution that seamlessly integrated double glazing into both timber and aluminium frames—enhancing thermal efficiency without altering the home’s aesthetic. Unlike many providers who shy away from retrofitting greenhouse windows due to their complexity, the  RetroGlaze Partner™ embraced the challenge, delivering a high-performance solution that improved warmth, reduced condensation, and maintained the home’s stunning natural light. The result? A warmer, quieter, and more comfortable living space where modern efficiency meets timeless design.
