You may have heard of sash window refurbishment but do not know what it is. Maybe you know about them and do not like the way they work, or do not work. Perhaps you wish they did work better, but do not know how they are supposed to work, or how they can be repaired.
The earliest known examples of these windows existed around 1658. They were used extensively in Victorian, Edwardian, and Georgian English homes. The version with both bottom and top movable panels was once widely used in the United States. Today they less common due in part to the availability of air conditioning systems. Many windows these days are designed so that they cannot be opened at all.
These ingenious devices were actually superior in that they have a bottom panel which can be opened by raising and a top panel which opens by lowering. This arrangement allows hotter air, which will rise to the top of a room near the ceiling, to vent out the top opening creating a slight vacuum in the room. As this happens, cooler, fresh air from outside will be gently sucked in through the bottom opening. This air, being cooler will tend to stay in the bottom of the room where the people are.
So in effect, a naturally operating circulation occurs, without an electrically powered, mechanical forced air system. This saves energy as well as wear and tear costs on the heating and cooling system. In this way maintenance or replacement costs are minimized or postponed.
While there is a lot of concern among the population about outdoor air quality, the fact is that indoor air pollution in the average home is up to seven times greater than outdoors. There are many reasons for this. Many building materials in homes, including paneling, drywall, carpeting, and paint contain toxic chemicals, like formaldehyde, which continually out gas into the air. This is also the case with furniture, typical household cleaning chemicals, pesticides, so called air fresheners, scented candles, and perfumes body care products.
Especially hazardous are newer homes. In the first two years of a home's life many of these toxins are depleted and filtered out by the inhabitant's lungs and bodies. While occasional exposure to small amounts of these chemicals may not seem to have a noticeable effect on a person's health, the cumulative and long term effect can be severe.
Many toxins never do leave the body, and a toxic load can accumulate that the body simply cannot cope with any longer. Chronic and sometimes mysterious health problems may begin to manifest. They might not ever be consciously associated with home air quality.
The level of individual toxins could be insignificant but the cumulative effect of hundreds or thousands can have a major effect on the inhabitant's health. Buildings that are sealed tightly and recirculate the same toxic air can have dangerous buildups of harmful chemicals. Air conditioners will not filter them from the home. Sash window refurbishment to make those windows work properly can be a step in the direction of creating a healthy environment at home.
