Window & door types

Between them, our members offer every type of window and door you could want. Each will be carefully designed to meet stringent weather testing and safety requirements - for example, opening restrictors are available to prevent children accidentally falling through the open window. All window types come double-glazed as standard and most are available with triple glazing. See our Energy-Efficiency Guidelines for Timber and Aluminium-clad Windows for more on glazing units. See our Guidelines on Narrow Cavity Insulated Glazing Units for advice on slimline double-glazing.
