Double Glazing for Aluminium Windows and Doors in Wellington.
When considering double glazing for your existing single-glazed aluminium windows, you need to know if there is a sill flashing underneath the existing window.

We’ll leave your existing aluminium window frames in place and replace your single-glazed panels with double glazed units. We’ll fit new aluminium beading to the fixed panels and add a new replacement extrusion for the opening sashes to allow for the extra thickness of the double-glazed glass panel.
