Alaskan Windows’ excellent secondary glazing will provide warmth and protection for your Cousldon house. Whether you live in a historic property, a conservation area, or simply want to improve your insulation without replacing your existing windows, our unobtrusive secondary glazing is a cost-effective and efficient solution.
Secondary glazing is the installation of a second pane of glass into an existing window frame. This creates a sealed area between the two panes, providing a similar effect to double glazing but without requiring the removal or replacement of your existing window. It’s an excellent choice for homeowners in high-traffic areas looking for relief from outside noise and heat loss. We’re delighted to provide high-quality, made-to-measure secondary glazing for homes in Coulsdon.
We partner with trusted manufacturer Granada to supply expertly engineered units tailored to your existing windows for a flawless fit every time. As a local installer, we combine competitive pricing with attentive, personalised service to ensure a smooth and stress-free experience from start to finish.

Every home is unique, and our solutions are intended to reflect this. Secondary glazing comes in a variety of forms, including fixed, sliding, hinged, lift-out, and tilt-in. We’ll recommend the best systems for your specific needs, whether you want better insulation, better acoustics, or easier window cleaning.
Our glass is slimline and discrete, providing optimum performance while minimising visual effect. Every installation is custom-measured and completed by qualified professionals to achieve a smooth finish that complements your interior style while keeping the appeal of your property.

Secondary glazing provides tremendous benefits to Coulsdon homes by boosting both thermal performance and acoustic comfort. Secondary glazing provides a very effective layer of insulation by adding an extra interior pane of glass and creating a sealed air gap between it and the original window. This helps to keep warm air inside your home during the winter months, reducing heat loss and making it easier to maintain a pleasant indoor temperature. As a result, you may rely less on central heating, resulting in significant savings on your energy expenses over time.
In addition to thermal insulation, secondary glazing is a fantastic solution for noise pollution, which is a prevalent problem in busy areas such as Coulsdon, where regular traffic, trains, and public events disrupt daily life. Our high-performance systems are specifically engineered to limit sound transmissions, resulting in a quieter, calmer indoor atmosphere whether you’re working from home, resting, or entertaining visitors.

Adding an interior layer helps with both insulation and security. Our strong secondary glazing units serve as a secondary barrier against potential break-ins, with locking features and toughened glass to safeguard your property even further.
For listed or conservation properties in Coulsdon, typical double glazing may not be feasible due to planning constraints. Secondary glazing, on the other hand, is a non-invasive option that maintains the outward appearance of your windows while providing considerable modern benefits, increasing the likelihood of compliance with planning rules.
