Window components are the wide variety of different elements which make up individual glazing units and glazing systems.

Types of window components include glazing panels, sills and lintels, frames and subframes, mullions and grilles, vents and trickle ventilators, weep holes, cavity closers, gaskets and sealants, weatherstripping, dust pads, locks, latches, catches and handles.

Modern windows are generally prefabricated off site, and require a large number of different components to function properly. Whether timber, aluminium, steel or upvc, windows are complex building elements which require a thorough understanding to specify.
