Retrofit Double Glazing for Auckland Villa & Timber Windows
Keep the original character of your home while enjoying modern warmth and comfort. We specialise in retrofitting high-performance double glazing into existing timber sash and casement frames.
Thermal performance for heritage homes
Retrofit double glazing is the process of replacing the single pane of glass in your existing timber windows with a modern Insulated Glass Unit (IGU).
Unlike full window replacement, we keep your original high-quality timber frames. This makes it the most cost-effective way to double glaze your villa without losing its heritage soul.
Retrofit vs. Full Replacement
Many homeowners believe they need to replace their entire window to get the benefits of double glazing. In most cases, your original timber joinery is superior to modern replacements if properly maintained.
- ✓ Cost-Effective: Significant savings compared to full timber or aluminium replacement.
- ✓ Preserve Character: Keep the authentic look and feel of your heritage villa.
- ✓ Sustainability: Less waste and reuse of existing high-quality timber.
- ✓ Fast Installation: Less disruption to your home and no need for major structural changes.
