ACH 121 Lecture 12a Doors
- 14. Types of Doors: Stile & Rail Panel Doors Glass & Louvered
- 33. Locksets & Strikes Deadbolt Lockset Strike Plate
Hinweis der Redaktion
- Flush: plywood, hardboard or plastic-laminate face panels bonded to solid or hollow-core Stile-and-rail: vertical and horizontal members enclosing wood, glass, or louver inserts creating panel, sash, storm, screen or louver designs Accordion Fold: assembled from narrow slats that give long, drape-like appearance
- Increases the dimensional stability of a door Provides thermal insulation, sound insulation & fire resistant Fire rated wood doors range from 20 minutes to 1 ½ hours Solid-core material: wood, particle board, mineral composition or combination
- Glue-Block Core Most common construction Wood blocks bonded together, with end joints staggered Stiles & rails are bonded to core Entire assembly is sanded to a smooth, uniform thickness Face panels are bonded or glued to the assembly Must meet a min. of 1/12 thickness
- c. & b. Framed-block core: stile and rail frame surrounding an interior core of wood blocks, which may or may not be bonded together, but are bonded to face panels d. Stile-and-rail: consists of wood blocks bonded into stile and rail panel units; Particle-board core: constructed of one or more pieces of particleboard, each the full thickness of the core, may or may not be glued or end-glued together. Stiles and rails may or may not be bonded to core e. Mineral-composition core: only available in fire-rated doors, similar to particle board core doors, core is made of inorganic, non-combustible material formed into a rigid slab. Special blocking and framing are normally required to accommodate hardware, glazed openings and other cutouts f. wood-block, lined core: combination of previous constructions, central wood-block core, with a 3/16” or thinner liner of particleboard or other material bonded to each face to constitue core thickness. Face panels are bonded to assembly and stile & rail frame. Provides added sound insulation, fire resistence
- Do not provide much thermal insulation or sound insulation Used in interior applications
- Mesh: wood or wood derivative material joined, interlocked or woven together to form a grid or mesh; honeycomb cores of expanded paper are most common cores Ladder Core: wood or wood derivative strips placed horiz. Or vertically
