We supply all the steel casements required for our stone mullion windows. These are supplied galvanised as standard, with a high performance rubber weather strip between the leaves of the opening casements. The casements can be powder-coated if required (normally black) and can be supplied with a choice of traditional stays and fasteners if required. We can also supply these to custom sizes for use in existing stone windows in your house. They can be made to accommodate double glazed units of various sizes or alternatively you can use our traditionally made leaded multi-pane lights.
