Energy efficient windows

Windows have long been used in buildings for daylighting and ventilation. Many studies have even shown that health , comfort , and productivity are improved due to well-ventilated indoor environments and access to natural light.

Glass as an independent object mostly as beads dates back to about bc. It originated perhaps in Mesopotamia and was brought later to Egypt. Vessels of glass appeared about bc , during the reign of Thutmose III , a pharaoh of the 18th dynasty of Egypt. From Mesopotamia and Egypt, glassmaking using the basic soda-lime-silica composition traveled to Phoenicia, along the coast of present-day Lebanon. From there the art spread to Cyprus, Greece, and, by the 9th century bc , the Italian peninsula.

After the conquests of Alexander the Great in the 4th century bc , glassmaking skills spread to the East, including the Indian subcontinent.

It is a non-destructive analytical technique that provides a wealth of information, including element mapping. Decorated windows have been a feature of English churches for over years, depicting scenes from the Bible, the lives of saints, royalty, heraldry and benefactors. In some cases the glass remains in its original windows, but more often it has been moved at least once and many windows have been destroyed.

This makes it difficult or impossible to reconstruct the windows and identify the decorations. On many fragments the decoration is completely obscured. There are over fragments of glass, generally in poor condition.

Characterization of archaeological and in situ Scottish window glass

The history of antique window glass goes back to a time just before the turn of the first century AD. Phoenicians along the Syrian-Palestinian coast developed a technique of glassblowing that allowed for a variety of shapes of hollow glass items. Spreading throughout Germany, Italy, France, and Switzerland as a result of the rise of the Roman Empire, glassmaking flourished and the Romans began using it for architectural purposes.

It wasn’t until the 11th century that the mouth-blown cylinder technique of making sheet glass for windows was first developed in Germany and later adopted by the Venetians.

Historic building window replacement presents a variety of challenges. Each design parameter affects the others. For example, historic requirements may mandate narrow sight lines to replicate original glazed wooden sashes. New insulating glass might impact the muntin profiles or change shadow or sight lines. A custom finish that eliminates the need for repainting may require thermally separated aluminum framing with deep glazing pockets.

Deteriorated building framing may require a custom window rather than an off-the-shelf product. The biggest concern with glazing replacement in an historic building of any kind is not knowing what might be uncovered during demolition. The owner, architect, and glazier cannot know the true condition of the wall until the old windows have been removed and demo is complete. Often, the historic opening is out of square, either due to primitive early construction methods or building movement over time.

The difference may be subtle or significant. There may also be structural issues associated with deteriorated window framing or deteriorated masonry around the opening. Repair measures may affect glazing dimensions and the type of glazing system or product specified. Once demo is complete and the design and construction team can assess the historic building conditions, there are many devils that influence the details. The need to retain historic building fabric — from the exterior wall material to interior finishes — may require creative solutions so that windows fit precisely into original openings.

Early manufacture of glass involved single sheets of glass manufactured by a craftsman by blowing through a tube. Generally the further back in history you go, the wavier the glass is. Wavy glass is the cool-looking glass commonly found in older window panes, doors, and furniture built prior to the early s. Early glass also has tiny bubbles called seeds.

Historical items dating to the 15 th —18 th centuries will be displayed in a glass case right on the street. It was uncovered this May during archeological monitoring in the course of a Maly Zlatoustinsky Pereulok-Armyansky Pereulok crossing project. There will also be nine carved gravestones under the glass and a piece of the 19 th century stone pavement restored around the showcase. There will be metal railing around it. The exhibit will be illuminated to highlight the details.

The installation of the museum window is being carried out by the Moscow Department for Major Housing Repairs. While clearing the spot we found three fragments of 17th century gravestones. Regarding the foundation, experts had to restore the masonry in several places using original materials. The difference between the new and original parts can be seen in the colour, texture and joint sealing. According to Yemelyanov, archeologists also found six other gravestones on Maly Zlatoustinsky Pereulok and Armyansky Pereulok where an old church graveyard once was.
