Wood will expand and contract across the grain, and a wide panel made of solid wood could change width by a half of an inch, warping the door frame. By allowing the wood panel to float, it can expand and contract without damaging the door. A typical panel would be cut to allow 1/4" (5 mm) between itself and the bottom of the groove in the frame.
Grooves are used for a range of purposes in cabinet making and other woodworking fields. Typically, grooves are used to house the panels in frame and panel construction and the bottoms of drawers. For more structural construction, grooves are created along the sides and/or ends of panels, such as in tongue and groove construction. [2]
Cross-laminated timber (CLT) is a subcategory of engineered wood [1] panel product made from gluing together at least three layers [2] of solid-sawn lumber (i.e. lumber cut from a single log). [3] The grain of each layer of boards is usually rotated 90 degrees from that of adjacent layers and glued on the wide faces of each board, usually in a ...
Laminate panel is a type of manufactured timber made from thin sheets of substrates or wood veneer. It is similar to the more widely used plywood, except that it has a plastic, protective layer on one or both sides. Laminate panels are used instead of plywood because of their resistance to impact, weather, moisture, shattering in cold ...
Hollow core doors are much lighter than solid wood doors, cheaper and are easier to install. However, sound travels more freely through them, which can be a problem if the house is noisy or the occupants desire a lot of privacy. Also, hollow core doors should not be used as doors to the outside because they can more easily be broken open by ...
Large self-supporting wooden roof built for Expo 2000 in Hanover, Germany. Engineered wood, also called mass timber, composite wood, man-made wood, or manufactured board, includes a range of derivative wood products which are manufactured by binding or fixing the strands, particles, fibres, or veneers or boards of wood, together with adhesives, or other methods of fixation [1] to form ...
The creation of pressed wood begins with the veneers [2] being placed in a rotary dryer. [3] This dryer is typically heated with steam at around 204 °C (400 °F). This process prepares the veneers for the humidifying process in which the veneers are then placed into humidification chambers.
