Young Curly Brunette Girl In Front Of The Wooden Door

• A French door is a door (installed singly or as one of a matching pair or series) consisting of a frame around one or more transparent and/or translucent panels (called lights or lites); it is also called a French window as it resembles a door-height casement window. A pair of French doors does not generally include a central mullion (as do some casement window pairs), thus allowing a wider unobstructed opening. The frame typically requires a weather strip at floor level and where the doors meet to prevent water ingress. An espagnolette bolt allows the head and foot of each door to be secured in one movement. The slender window joinery maximizes light though into the room and minimizes the visual impact of the doorway joinery when considered externally.
• A louvred door has fixed or movable wooden fins (often called slats or louvers) which permit open ventilation while preserving privacy and preventing the passage of light to the interior. Being relatively weak structures, they are most commonly used for wardrobes and drying rooms, where security is of less importance than good ventilation, although a very similar structure is commonly used to form window shutters.
• A composite door is a single leaf door that can be solid or with glass, and is usually filled with high density foam. Most composite doors carry secured by design accreditation and PAS 23 and PAS 24.
• A flush door is a completely smooth door, having plywood or MDF fixed over a light timber frame, the hollow parts of which are often filled with a cardboard core material. Skins can also be made out of hardboards, the first of which was invented by William H Mason in 1924. Called Masonite, its construction involved pressing and steaming wood chips into boards. Flush doors are most commonly employed in the interior of a dwelling, although slightly more substantial versions are occasionally used as exterior doors, especially within hotels and other buildings containing many independent dwellings.
