It is possible to build an entire house, using wood only. None of the materials used in constructions offer such versatility. According to current researches, around 40 % of people in Germany and 80 % of people in Scandinavia prefer wood as residential building material. The share of wood as an architectural material achieved an important increase between the years of 1991 and 2002 in Germany.

Wood is healthy: Wood does not attract dust. It acts as a regulator, absorbing and emitting the humidity in the space it exists. It provides heat insulation higher than its alternatives thanks to its cells filled with air, preventing heat transfer. Heat conductivity of wood is typically as low as 0, 13 W/mK. Therefore, wood is used in making handles of mechanical components, decorations of ceilings and walls. The heating ratio of wood is fairly high. This means that it requires much energy for increasing and reducing the temperature of a wooden material. Wood needs as twice heat energy than stones and concretes. Likewise, it needs three-times more heat energy than that is used for heating and cooling steel.

Wood is economical. The life span of wood as a construction material, is commonly projected as 80 years, with a lot of wooden buildings dating from middle ages showing that this duration may well be past. The prejudice that wood needs frequent care is a reminiscent of those times that people thought it necessary to cover wood surfaces with impermeable films of paint.

Wood has unique technical properties. Materials expand with heat. Expansion causes decrease in strength of materials. Since steel is inorganic and non flammable, it is resistant to combustion. However, when it is used in buildings, it expands and collapses as a result of increase in temperature. Wood almost never expands with temperature. On the contrary, it dries and gains strength with the effect of heat.

 wx=Wood is superior in sound insulation:

Sound insulation depends on surfacial mass. Hardwood is ideal for sound absorption. Wood prevents echo and noise by absorbing them. Hence, it is commonly used in concert halls. On the other hand, sound is transmitted faster in wood than gases and liquids. It is very close to the rate of transmission in metals. The loss of sound energy as a result of friction is low in wood as a matter of its lightness and structure. Wood is widely used in musical instruments for these and other similar properties.

Wood is safe: Water and carbon dioxide emerges when wood is burnt. You can take a look at a Greenpeace report if you wonder what kind of things emerge when alternative artificial materials are burnt.

PVC Information

 wx=Wood is beautiful: Wood is a decorative material when considered from the aesthetic point of view. Each tree has its own naturally formed color, texture, grain and even scent. The structure of a wood changes according to the way it is cut. It is possible to find different wooden materials fitting different preferences of design and color. It can be painted with darker colors or can be shaded to lighter or darker tones during use. All these make wooden products distinctive, individual and unique to the user. Users feel happy when their personal styles reflect on to their environment with different windows designs. Wood windows and doors are fundamental components in interior decoration along with other architectural components such as flooring and furniture.

Wood is a traditional building material for all cultures from East to West. Since its value is long engraved in human subconscience, it is a common source of warmness for people of all cultures. Because of the fact that wood is the material of both ancient and modern times, it is the ideal choice for a wide array of projects from renovations to avant-garde buildings.
