Casement Window Retrofit Double Glazing

Casement Windows: Retrofit Double-Glazing

Improve comfort and energy efficiency without changing the look of your home. High-quality double glazing tailored for traditional timber casement windows.

Modern Performance

Quiet, warm, and efficient

Casement windows are a beautiful feature of many Auckland homes, but older single-glazed units can be a major source of heat loss. Our retrofit solution replaces the single pane with a high-performance IGU (Insulated Glass Unit).

By upgrading your casement sashes, you'll enjoy a warmer home in winter, a cooler home in summer, and significantly reduced outside noise—all while maintaining the authentic heritage aesthetic of your timber joinery.

We use high-quality materials that comply with NZ/AUS standards, ensuring your investment is protected for years to come.
