Secondary Glazed Windows and Doors for your Morden Home

If you live in Morden and want to improve the performance of your traditional windows without replacing them, secondary glazing could be the ideal solution. Many period properties feature original windows that add charm and character, but they may no longer meet modern energy efficiency standards. In fact, up to 10% of your home’s heat could be escaping through single-glazed panes.

Secondary glazing allows you to enjoy the best of both worlds. By installing a slimline, made-to-measure unit over your existing window, you’ll create an extra insulating layer, similar to double glazing, without altering the appearance of your property. This added layer improves thermal efficiency, reduces draughts and condensation, and helps preserve the condition of your original windows.

At Alaskan Windows, we specialise in secondary glazing for heritage and character properties in Morden and the wider London area. Our discreet, high-performance units are suitable even for listed buildings and conservation areas, helping you boost comfort and efficiency without compromising your home’s style or history.

Variety of Styles

Our secondary glazing is available in a range of styles to suit different window types, including hinged units for single casement windows and horizontal sliding systems that can accommodate up to five casements. Hinged options can also provide fire escape access where required.

If you have traditional sash windows, we offer vertical sliding units designed to mirror their function and appearance. Whatever style you choose, all units align precisely with your existing frames, ensuring a discreet internal finish and minimal visual impact from the exterior.

With Alaskan Windows, you can also get made-to-measure secondary glazing for any window. We custom cut our glass to your specifications, meaning we can provide secondary glazing for a range of window styles. Whether your designs are small or expansive, we can provide a unit that offers complete coverage for your classic windows.

Improved sound Insulation

Morden has a vibrant community, but with that comes busy streets.  Alaskans’ secondary glazing can act as a powerful sound barrier, reducing external noise.  As part of our partnership with Granada, we offer units that achieve remarkable noise reduction to make your home peaceful. With one of these units, you can achieve a larger gap between glass panes than with new double glazing, meaning the sound waves have to travel further.

Frequently Asked Questions

Secondary glazing is a type of glazing that helps to improve the thermal performance and noise pollution. This type of glazing can be fitted into all door and window frames.

Our secondary glazing will help keep your home warmer during the colder months of the year by retaining heat and keeping cold air from entering your home. You can also benefit from improved sound insulation, keeping noise pollution out.

Secondary glazing offers better thermal performance and noise pollution reduction than double glazing. The extra layer of glass works to block out unwanted noise, whilst also retaining heat in your home for longer.

  • Perfect professionalism from first point of contact to cleaning up after work. Very consistent and thorough in communication. Prices are upfront and fair and most importantly - finished product is perfect. So happy I found them on Checkatrade and decided to solicit a quotation from them. Local London shops and nationwide leaders didn't measure up!

    Customer, Dulwich, London

  • Three workmen carried the work out in just two days, friendly hard working.Douglas and Alastair very friendly and helpful salesmen - never pushy. Great family business - reliable and efficient from start to end.

    Mr Jeeves, Croydon

  • We had a great experience working with Alaskan Windows. Great communication and friendly staff. The work was completed in a timeframe that suited us and to a high standard. No complaints and would recommend to anyone. Thank you.

    Claire Archer

  • A very good experience from start to finish. Replacement of two old windows on 3rd floor of block of flats required advanced liaison with Block Management and scaffolders. The fitting day went well with all mess cleared away and finish well within the time quoted. Will definitely consider involving Alaskan in replacing two large living area windows at the property.

    Jeremy Noble

  • Professionally run company, quality products, very high quality installation and also a competitive price. I have used them on more than one occasion and happily recommended them to friends and family. I would certainly use Alaskan Windows again in the future for all double glazing requirements.

    Stuart Cooke

  • Absolutely thrilled that we chose Alaskan Windows for our window replacement! The sales team were fantastic—so patient and clear in explaining everything, especially since we didn’t know much about the different types of windows. No pushy sales tactics at all, and the price was surprisingly competitive. Huge thanks to the installation team—you did an amazing job! And a big shout-out to the admin team for making the payment process, documentation, and warranty follow-up effortless. Our home feels so much warmer now, and it looks incredible with the new windows!

    Albert Salihu

  • We have been so pleased with Alaskan Windows. From start to finish they have kept us informed, been clear on everything, kept all appointments, worked tidily and respected the property.
