Modern Manufacturing Processes For Wooden Sash Windows Leave Craftsmen In The Dust
Sash windows are old-fashioned and are found often in Georgian and Victorian homes. Made by hand, there were irregularities in windows that over time made the windows warp in the frames, letting in cold and noise. Modern manufacturing processes for wooden sash windows have eradicated these problems.
A sash window opens by sliding up and the original design had a rope and counterweights built into the frames that were used to keep the window at the level it was opened to. Walls were thick however in old houses and a modern house cannot fit the width of these windows. The modern method is a friction track to hold it open.
These windows were made by skilled craftsmen for much of their history and their quality depended on what skills the craftsmen had. Slight defects that were originally unnoticeable become gaping holes as the elements take their toll over the years. For this reason, architects provide CAD drawings which are now used to program the machines making the windows.
Modern building standards have forced manufacturers to greater accuracy as durability, insulation and security requirements are part of the building codes. There are also many more constructions happening simultaneously and the old methods would never provide this standard. Machines just do the job better.
The client chooses the basic design and items such as locks, hinges, handles and glass type are made accordingly to his or her recommendations. The colours and varnishes used can also be changed as needed. Windows that allow sunlight in, keep heat in and sound out are preferred.
Once the window is completed, the wood is sprayed with three coats of water-based micro-porous sealant that reduces maintenance. Then an environmentally-friendly preservative that has a long service life is used to protect against attack by fungus or insects. Water-based spray paints are used for a primer coat to fill the pores in the wood. This will prevent water penetrating into the joins and seals. Two top coats of paint or stain, chosen by the client, give a finish resistant to wear and tear.
Gasket complete the sealing of the window as they come between a window and its frame. The gasket does not get twisted or warped and therefore keeps out the cold, keeps in the heat and reduces noise pollution.
The modern manufacturing processes for wooden sash windows involves CAD technology, hydraulic cramps, quickset moulders and computerized morticing systems. Managed by control software specific to each manufacturer, a production management database controls the whole manufacturing process to schedule.
