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.
These have probably existed since at least 1658, beyond that we do not know. They were commonly used in Edwardian, Victorian, and Georgian style homes in England. A double panel version, with both top and bottom movable panels, became quite popular in the United States. Lately they have become less so with increasing use of air conditioning systems. It has become common for many windows to be designed not be open-able at all.
These efficient devices are superior in performance and provide healthier air. Having a top panel that opens downward and a bottom panel which will open by raising, openings at two different heights are created. This results in a natural circulation of air in the room. Hot air rises toward the ceiling and finds its way out the top. As it leaves the room it draws cool, fresh air into the room from below to replace it. This cooler air stays near the bottom of the room and acts to force warm air out the top.
Thus we have a naturally operating system of air circulation, saving electricity and wear on the forced air system. That system can be reserved for very hot days or parts of days. In this way maintenance work and system replacement can be delayed and minimized.
There seems to be much concern about outdoor air pollution. It is known however, that indoor air quality in the average home is about seven times worse than outside. There are several reasons for this. The materials used in much home construction is laden with chemicals like formaldehyde which continually out gas into the air. Examples of materials are carpeting, paneling, paint, and drywall. Furniture materials have the same problem. Also pesticides, so called air fresheners, home cleaning products, scented candles, perfumes and body care products give off large quantities of toxins.
New homes are especially hazardous. Many of these chemicals are depleted in the first two years after construction, and filtered from the building through the lungs and bodies of the inhabitants. Exposure to small amount of chemicals may appear to not have any observable effect on someone's health. The cumulative effect, however, can be drastic.
Some toxins never are expelled from the body and the toxic load can build to a point where the body is simply unable to cope any longer. Mysterious, chronic health issues may start to show up. These might not ever be associated with toxic air at home.
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.
