Description

PVC ENCASED WOOD Field of Invention

The present invention relates to window and door profiles with the main body produced from wood and the external surface, i.e. the surface that faces outwards is manufactured from PVC material.

Prior Art

PVC material is being widely employed in window and door systems nowadays. PVC materials are amongst indispensable construction materials used in/on external surfaces, i.e. facades of buildings, particularly due to the high strength they have particularly against external factors. Especially in countries such as Turkey where intense rainfalls and rapid climate alterations are being experienced, doors and windows produced from PVC material, or even the incasing of facades of buildings by PVC material bring about substantial advantages for users. PVC materials, on the other hand, cause a significant 'visual pollution'. Additionally wastes emerging as a result of PVC material applications do pollute the environment significantly. Moreover, the PVC materials are not rapidly degraded in nature like wooden materials are. Waste materials maintain themselves for relatively longer periods and their degradation takes long.

The replacement of wooden materials by PVC resulted in insulation problems as well. This polymeric material is weaker with respect to heat-insulation as compared to wood. Thus, any lack in providing heat insulation in buildings causes the fuel consumption to rise, thereby wasting relatively more energy. In order the overcome this problem, extra insulation materials are employed in buildings, resulting in cost increases.

The carcinogenic effect of PVC is known widely nowadays. What matters in this respect is the manner such PVC material is produced. The VC monomer and the additives employed must be discussed and evaluated individually, if the carcinogenic effect of this material is to be considered. The material called as the VC monomer is vinyl chloride, which is produced from petroleum and salt during the first phase, and which corresponds to the incompletely polymerized form of PVC. Another fact known for a long time is that the direct intake of this substance leads to a particular type of cancer that focuses on the liver. With the air -that can not be controlled during PVC production in plants- escaping to the outer atmosphere, both the environment and naturally the workers within the plant are exposed to serious risks with respect to health. On the other hand, if no complete polymerization can be ensured during production, some amount of VC is retained in the PVC being produced. As a result of this fact, such PVC materials applied to windows and doors and to almost everywhere in buildings cause the persons living there to become intoxicated slowly. Another health-related problem that emerges during the production of PVC material is the additives. Additives such as stabilizers and pigments, heavy metal salts, fillers, and lubricants are employed to enhance the strength and/or the features such as heat and light insulation of PVC material. It is particularly dangerous if lead-type heavy metals and salts are accumulated within the human body.

Another issue in relation to the use of PVC materials is the occurrence of evaporation particularly on window panes. Water droplets form on the pane surface and window edges depending on the temperature difference between the interior (i.e. indoor side) and the exterior (i.e. outdoor side). Evaporation occurs more frequently in winter months. In order to avoid this problem, the interior places must necessarily be aerated 4 to 5 times a day. Aeration, however, leads to heat loss in the interior, resulting in an extra energy consumption.

Even though full-wooden windows seem to solve all such problems, they actually fail in providing a complete solution. Although wooden material is environment-friendly and provides a nice aesthetical view to users, it nevertheless requires maintenance and repair in certain frequencies, bringing about economical and practical concerns. In ecology, like the one of Turkey, involving intense rainfalls almost during all seasons, the necessity enhances towards maintenance and repair.

In brief, the inadequacy of present solutions and the necessity towards healthy and highly endurable window and door profiles, eliminating the present drawbacks of currently-used window and door profiles caused such a development be made. Objective of Invention

Accordingly, the present invention aims at solving the aforesaid problems.

The objective of the invention is to combine the advantages of both materials, i.e. of wood and of PVC, in a profile, by applying PVC onto the surface of wooden profile body facing the outdoor side to provide aesthetical appearance, healthy material, and high endurance.

Another objective of the present invention is to protect the user of such profiles against the effects of PVC material on human health, by producing the surface of profile facing the indoor side from wooden material completely.

A further objective of the present invention is to provide high endurance against external factors so as to reduce the necessity towards maintenance and repair and to render the situation more economic, by encasing the faces of profiles only that face the outdoor side with PVC material.

Yet a further objective of the present invention is to avoid the deformation and degradation of wood in time, by means of applying a tooth-joint system or encasing PVC on the outer section.

Still a further objective of the present invention is to both enhance the lifespan of profile and to save energy, by combining the strength of PVC material with the heat- insulation feature of wooden material.

Structural and characteristic features, and all advantages of the present invention shall be made clear by means of annexed figures described here below and a detailed description written by making references to said figures; therefore the present invention must be evaluated by taking said figures and the detailed description into consideration.
