This is part three of our blog series, The ABCs of Doors & Windows. Follow the links to read parts One and Two.
Brick Mold Casing (BMC) – This is the exterior molding on a window or door frame that sits against the structure’s exterior material, serving as a decorative boundary for siding, brick or other material.
Casing – The casing is the interior trim that surrounds the window or door which covers the gap between the window/door and the drywall, hiding the frame, insulation and caulking.
Cladding – The vinyl, fiberglass or aluminum jacket that covers the wooden core on the exterior side of a window or door is called the cladding. It helps preserve the wood and improve its weather resistance.
Divided Lites – Divided lites create the look of multiple, individual panes of glass in a window or door. They can use many different panes of glass or they can be simulated to mimic the look of multiple panes to take advantage of the improved energy efficiency of a single pane. Divided lites are popular in a wide range of architectural styles, from historic replications to modern farmhouses.
Insulating Glass (IG) – This glass assembly consists of two or more sealed glass panes separated by a space between to reduce heat transfer. Insulating glass, which can contain argon for improved thermal insulation, is one of the most impactful window and door features in terms of energy efficiency.
Obscure Glass – Often used on entry doors and bathroom windows, obscured glass features a pattern in the pane that provides privacy while maintaining full light transmission.
Screens – Screens are made of close-mesh woven material of metal or fiberglass attached to an aluminum or wood surround, inhibiting the entry of insects while still permitting light, air, and field of view when windows and doors are open.
Tempered Glass – This safety glass is required for large windows and windows that are low to the ground. The glass is heated and then cooled rapidly in a controlled environment for added strength. The tempering process also makes the glass safer due to the pebble-like fragments created when shattered.
Transom – These windows are located above the main window or door and can be either stationary or operating. They allow more light to enter while also adding a decorative touch.
Weather Strip – Made of felt, foam tape or formed plastic, this strip of resilient material around the door or window reduces air and water infiltration by sealing the sash and frame.
