The Modern Manufacturing Processes For Wooden Sash Windows Researched
September 3rd, 2010Modern manufacturing processes for wooden sash windows have not changed all that much over the years, since custom work dominates this field, whether the units come from a national company like Sears or a local woodworking mill. There are standard window sizes which are available as well from building supply houses and online sites.
Wood has more insulating qualities than metal, is considered more decorative as an architectural element, and is the most traditional material. Wooden sashes, which consist of one or more panels that move vertically, began to replace casement windows (hinged on the sides and swinging outwards) in the early 18th century. The elegant architecture of the Georgian period in England and the Colonial days in North America has led to a preference for sash windows up to the present.
Windows with sashes and frames must have tight joints, properly slanted sills to drain off water, and balance weights or other devices inset that keep them in the desired position. Expert craftsman are just as important today to properly assemble products. Many premier makers are located in the United Kingdom and in Canada, but all manufacturers offer custom work from precise measurements and ship their products all over the world.
If the house is a standard, modern design, if energy efficiency is paramount, or if expense must be kept low, factory windows may be chosen rather than custom designed ones. Some are manufactured to comply with regulations that will qualify the home improvement for tax credits. Others fit modern houses which are designed to use mass produced materials.
Even quality reproductions, made unit by unit on demand, may have special porous paint that is waterproof, while allowing the wood to breathe out moisture for longer life. Panes may be single, or many set in wooden frames, and the glazing and caulking must be expertly done for years of weather resistance. New windows may be double glazed for additional insulation from heat, cold, and sound, or made with special acoustic or thermal glass. The traditional look of a classic home is preserved while the homeowner still gets the benefit of modern technology.
Even for those who must follow historic guidelines, who choose to retain the integrity of a certain style, or who can afford the cost of custom work can benefit from new advances in this field. New types of paint can be completely waterproof while allowing the underlying wood to breathe, or release moisture which, if trapped, would cause eventual rot. New types of glass can deaden sound, and double glazing (using two panes of glass with an air layer in between), will provide more insulation from both temperature extremes and noise.
Modern manufacturing processes for wooden sash windows are a mix of old technology and new, with the best of both offered for new construction or replacement.
