Choosing Windows

Wood, aluminum, wood, aluminum, plastic (PVC), fiberglass and other window constructions are widely used market to ensure the highest consumer characteristics such as heat protection, aesthetics, reliability, and much more. Choose between wooden and plastic windows can be primarily guided by price category. Modern plastic windows are more focused on large-scale construction, they long-lasting and undemanding in operation. Modern wood windows, if in their manufacture have been met the requirements of relevant technical regulations on service life are not inferior plastic, but Operating wood windows require a great deal of attention. Design decisions, like plastic and wooden windows can be equally spectacular. However, the level of ecological safety of wooden windows in a number of cases may be disproportionately higher. Windows should be beautiful. Plastic with a stretch of the imagination be called handsome, his job is to make the window less than beautiful. Plastic window over time lose their appearance. Plastics can not renew, it is not repaired. If you have the look of windows is important, you need a box of wood. Wooden windows – is, first of all, indicator of housing quality. Bruce Schanzer shines more light on the discussion. Tree because of its natural unique properties has a greater insulation than plastic or metal. Wooden windows are not loaded electrostatically, and therefore do not attract dirt. Wooden box made of pine occupy the most successful niche market for money. Choosing eco-friendly, ergonomic and inexpensive wooden box made of pine, you'll spend a little more than windows, but get much more – above all, natural and totally harmless to health material. In plastic and tree has its pluses and minuses. The tree restricts the builders during construction and repair work. The windows need to tighten the film, do not expose the solution to the tree and between the wings, and – most important to observe humidity regime. Paintwork must renew in 10-15 years or once in two years, after washing the windows to wipe them with a special solution. Plastic eventually loses the appearance of his can not renew, he is not repaired. In the case of shrinkage of a house or other movements, and at very low temperature plastic can crack, it is necessary to replace the whole sash or window. In severe frosts may occur separation from the mounting box foam, as a consequence begin freezing slopes, or podduvanie. pvc does not have a crystal lattice or the preferred direction of strength – it is slightly runny stuff, so time is sagging doors. pvc electrified and, consequently, attracts dust. Residents of northern Europe, where climatic conditions are comparable to ours, have long appreciated all the advantages of wooden windows. The peak drag plastic there has already passed, and 70-80% now installed in the Scandinavian countries of windows – made of wood.

In Germany

Increasing housing density and increase in ambient temperature compared with the country territories – now well-known phenomenon that became known as the "urban heat island." Many researchers predict that green roofs could become a tool with which you can reduce overheating of the big city in the summer. The presence of vegetation on the roof closely mimics the natural environment, thus increasing the amount of greenery, the evaporating moisture and provide shade on the roof surface. Evaporation plant, located on the roof, as well as "shadowing" roofs – the main factors influencing passive cooling of roof in the hot season. As a consequence of these factors reduces the ambient temperature, because less heat is reflected back into the atmosphere. The vegetation on the roofs of the town a positive effect on ambient air quality, because it "captures" solid particles in the air, and also binds carbon dioxide – the main product of "breathing" of the city. Green roofs are becoming more successful habitat for various rare and endangered species.

It is reported that in London alone on a series of green roofs biologists have discovered more than 50 species of spiders. In Germany, on the green roofs were observed nesting sites of rare birds. Thus, green roofs could help in increasing the diversity of wildlife, although this advantage is heavily dependent on geographic features. Green roof – a space created by the addition of over a traditional roof system of additional layers of fertile soil and plants. Not to be confused with the traditional green roof, roof garden, where plants are located in freestanding containers (tubs) on the roof terrace or operated parking facilities. .

Ventilated Facades: Main Structural Elements

Ventilated facades: Key Elements of Designs For additional warming of outdoor structures between the wall and cladding can be installed insulating layer – in this case, in this case ventilation gap is left between the lining and insulation. In the ventilated facade design individual layers are as follows: wall insulation, air gap, the protective screen. Such a scheme is optimal, because layers of different materials are arranged with decreasing indices of their heat, and resistance to water vapor permeability increases from outside to inside. 1. Bearing wall A wall is a fulcrum for system. At the device mounted facade, are essential parameters such as: deviations from the walls vertically and horizontally, "littered" corners that are detected by the method of surveying.

Also of considerable importance is the material of which it is built and its degree of wear (if you have any). 2. substructure construction consists of brackets that attach directly to the wall, and bearing profiles forming the skeletal system, with special fastener elements mounted plate (sheet) tiles. The main purpose of designs is to securely attach a plate coating and insulation to the wall so that the insulation between the panel was finishing the ventilation gap. This excludes adhesives and other "wet" processes, and all connections are made mechanically. 3. Heat and sound insulation layer itself insulating layer protects the wall by alternating freezing and thawing, thus equalizes the temperature fluctuations in the wall and prevents deformation, especially adversely affecting the high-rise buildings. Thermal insulation has other advantages – increases the heat storage capacity of the wall and increases the sound insulation in a wide range of frequencies more than twice.

Wood Housing Materials

Tree in Russia is almost always remained the most used wall materials for personal dacha construction: high heat insulation, the classic appearance of a relatively small cost and highest the degree of environmental friendliness – a long time to make the wood is really the best option. But significant negative qualities of the houses made of wood lot, which together with the incessant increase in the cost and decrease the quality of construction of wooden houses is the basis for the search of better building materials. But, the best substitute for wood, perhaps surprisingly, is the tree itself. Arbol – a modern lightweight concrete on porous aggregates, consisting in 70-85% of wood chips normalized size and mineral binders (cement). It was he who, in principle, a tree, all collected all the outstanding properties of this timber, but not has its negative qualities. In modern building wooden country houses the most famous have laminated board, a simple timber and logs. But the companies made these kinds of materials is rarely designed to build thicker walls thirty centimeters, previously logs of less than fifty centimeters were simply inapplicable in the construction of residential buildings due to significant heat loss.

In Our age is an acceptable tree diameter is virtually unavailable. A desire to retain the value of homes within reasonable limits, rarely allows for even relatively cool, but still produced a log in 30-35 inches. Therefore, the most frequently used is absolutely unacceptable for good homes – with a diameter of 20-25cm.
