Georgian and Victorian homes from the early parts of the nineteeth century have many fine examples of sash windows, which were fashionable although they could be draughty and noisy. Modern manufacturing processes for wooden sash windows have resolved many of these problems and made them popular again.
Sliding vertically, this window is designed to allow you to open them slightly without the upper window falling down. The older versions use a rope and sash weights inside the frame to keep the window open. Modern houses tend to have thinner walls which are not thick enough to house the old fashioned apparatus and the modern system of friction tracks are used.
These windows were only as good as the craftsman who made it and over the years any slight defects would have warped into large gaps between frame and window. Machines now take care of most of the process. Architects provide detailed CAD-generated detailed drawings and technical support and these are fed into the programming for the machinery.
The accuracy of machine manufacture and simulation models are necessary due to modern building standards related to durability, good insulation for noise and weather, and security concerns. Even the best craftsmen could not provide the number of windows built to standard that are required. Machinery is simply more accurate.
The client will choose what design to use and what colours or varnishes are used to finish the frame. Locks, hinges, glass, handles are all changed according to the client's wishes. Windows that keep the heat in and the sound out but let in lots of sunlight are usually chosen by clients.
The protection of the wood is a detailed process that involves spraying it with three coats of a sealant that fills microscopic spaces and reduces wear and tear. A preservative that extends the life of the wood by preventing fungus or insects from setting up home, comes next. A primer coat is sprayed on and provides a smooth surface for the final two top coats of paint or stain. This gives the wood durability and as the products used are all water-based, this process is environmentally friendly.
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.
