The Modern Manufacturing Processes For Wooden Sash Windows Discussed

Modern 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 is the preferred material for windows, having a higher insulating power than metal and being both beautiful and traditional. Sashes are the moving parts of a box window, the sections that move up and down to ventilate the room. This design dates from the 1700s, as a 'new' innovation over the casement window, which swung open from side hinges. The style has been popular ever since.

Many of the premier makers of wooden windows are located in the United Kingdom and in Canada. Local mills and carpenters can also do custom replacements on site or from precise measurements. Some mills dating from the 1800s are still operating, with their original equipment still in use. Although there are some modern improvements in window making, many projects require exact replicas or reasonable facsimiles of the original windows, and the old technology has not been surpassed.

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 though old tools and methods may still be employed in customizing windows, modern technology can be used to improve energy conservation, sound proofing, and weather resistance. Micro-porous paint allows the wood to breathe, releasing trapped moisture while waterproofing the window against the weather. Special acoustic panes can reduce noise from outside, and the transfer of heat and cold is slowed by thermal glass and double glazing.

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.
