Retrofit Double Glazing for Aluminium Framed Windows
We are licensed installers of the Ecosee solution for retrofitting double glazing into existing aluminium windows and doors.
The Ecosee system
Double glazing without new joinery
Ecosee is a resilient double glazing system specially designed to upgrade the performance of single panes in aluminium frames. It is cost effective to install because we only replace the glass without needing to change the frame.

Ecosee benefits

- The conversion is relatively straightforward – we simply replace the glazing bead that secures the single glazing with a new bead for the double glazed unit. The result is close to that achieved by new joinery.
- We use our own aluminium profiles, customised to suit any window or door frame, so there are no delays.
- Because double glazed units are heavier, we upgrade the window hardware. Sliding doors fitted with double glazing may need adapters installed.
- We also upgrade to safety glass where there’s a risk of someone walking into the door or window.
- More balanced indoor temperatures – cooler in summer, warmer in winter.
- Improved energy efficiency – lower power costs.
- Noticeable noise reduction.
- Less condensation and mould.
- Better protection for your furnishings from solar UV rays.
- Special glass options are available for extra insulation (argon gas), and UV blocking (low E glass).
The result: a warmer, drier, quieter and healthier home.

'Pay by the room' double glazing offer
This allows us to complete the double glazing of your existing windows in stages, as and when you can afford it.
There is no need, or expectation, for all the work on your house to be completed at the same time in one job.
We can work at your home every few months or when you have the budget. We will start with south-facing windows, and continue from there at a pace that suits you.

Is the work done on site?
Yes, the work is carried out on site. We only remove the glass from windows we are working on and replace it the same day, so your property is always weathertight and secure at the end of each day.
Will I need new aluminium window frames?
No. Usually, we can retrofit the double glazed units into your existing frames. If that’s not possible for some reason we’ll advise you.
Do you reuse any of the existing glass?
No, for best results we use completely new glass. That way we can guarantee the product. Your existing glass will be removed and recycled.
Do I need new hardware fitted?
Yes. Because the new units are heavier we’ll fit new handles and window stays as part of the process.
Can I change the shape of the window frames or swap an opening window for a fixed pane?
Yes. In some cases we can swap opening windows for fixed panes. We may also be able to remove crossbars in larger windows and replace them with a larger glass pane to improve the view. We can advise you when we undertake the quote.
