Enhance the comfort, energy efficiency, and security of your Surbiton home with bespoke secondary glazing from Alaskan Windows – South London and Surrey’s trusted glazing specialists. Whether you’re looking to improve insulation in a Victorian terrace or reduce noise in a modern flat, our custom-made secondary glazing offers a cost-effective, low-impact solution that preserves your existing windows.
Ideal for properties with single-glazed units, our secondary glazing is designed to create a sealed, double-glazing effect without replacing your original windows.
Secondary glazing involves the installation of an extra pane of glass on the inside of your existing window frame. This forms a pocket of air between the two panes, acting as an additional barrier against noise and temperature changes. The result? Better insulation, reduced condensation, and quieter living spaces – all without the need for disruptive renovations.
Our secondary glazing is slim, subtle, and virtually invisible from the outside, making it the perfect upgrade for period properties across Surbiton and the surrounding area.

Reduced Heat Loss:
Many homes in Surbiton feature traditional sash or casement windows, which often lack proper insulation. Secondary glazing improves thermal performance by trapping air between two panes of glass, reducing heat transfer, keeping your home warmer in winter, and helping you cut down on energy costs.
Noise Reduction:
Secondary glazing is highly effective at blocking external noise, particularly when there’s a large air gap between panes. Whether you live close to the train station, the A240, or a busy school run route, secondary glazing can significantly reduce traffic and urban noise for a more peaceful home environment.
Increased Window Security:
Adding a second internal pane strengthens your window against forced entry, acting as an extra security barrier. Our secondary glazing is available with lockable systems, strong aluminium frames, and tamper-proof fittings for complete peace of mind.
Preserve Your Existing Windows:
There’s no need to remove or replace your existing windows. Our installations are clean, efficient, and tailored to fit your existing frames perfectly. Whether you have original timber sash windows or steel-framed units, we provide a discreet solution that delivers modern performance with minimal disruption.

Every home in Surbiton is different, which is why we offer a wide variety of secondary glazing styles to suit your layout, budget, and needs. Choose from:
