Yes... The Double Glazing Company can retro-fit double glazing into aluminium joinery - windows and doors.


The old glass will be removed and the existing aluminium joinery modified to be able to allow the double glazing unit to be retrofitted.  For the most part, this will just require new beads to be fitted.  These beads will be colour matched to your existing joinery.


In some cases additional modifications are required.  The outcome is still the same - the windows will have new double glazing units fitted and you will barely notice any visible difference.

We have solutions for all joinery, no matter the age - if it’s robust, double glazing can be retro-fitted into it.
