“Dualglaze” is the brand name for the systems developed to enable us to carry out the retrofitting of new double glazing units into your existing aluminium window and door frames.  New aluminium extrusions have been created to enable this work to be carried out.

As we are also aluminium joiners, and in some cases have actually manufactured the original joinery, we believe we are the best placed to carry out this work. Many conversions are not straight forward and benefit from our aluminium joinery knowledge and expertise to ensure that the job can be completed, and completed correctly.
