Questions to Ask



The Double Glazing Company has developed the retroGLAZE® system for retrofitting double glazing into homes.  


The retroGLAZE® system works in any home, whether timber or aluminium joinery.  It is designed to use as much of your existing joinery as possible.  This results in less waste than other double glazing options while maintaining a high quality outcome.  The savings are significant: 35%-45% of the cost of full replacement.

For the most part, the changes will be virtually unnoticeable.

Take a look at the gallery to see some of the different doors and windows that we have double glazed.
