The main disadvantage of wooden houses is their tendency to shrink. Even after three years of operation, the value of this parameter can be equal to 2-3%. The humidity of the air and the degree of drying of the material before construction begins also greatly affect the behavior of wood.
Of course, the eye will not notice such fluctuations. But if you are going to put plastic windows, a casing in a wooden house will be a prerequisite for their installation. In the old days there were no problems with skewed doors and windows, since the log house was kept for more than a year under special awnings. Today, no construction company will offer you such working conditions, since cunning developers try to send goods to customers as quickly as possible. In this case, no one is already worried about quality.
By the way, what is a casing? In a wooden house - this is a special box that is installed in a window or doorway. It is designed to compensate for mechanical stresses and distortions that occur in any wooden structure. Stresses are evenly distributed along the duct, as a result of which the window remains intact, and the doors will close normally.
If the structure has more than one floor, then a casing in a wooden house should be mandatory. Its manufacture cannot be attributed to particularly simple works, and therefore it requires a sufficiently high qualification. You can make it not only from an array, but also a type-glue type. The most expensive construction will be a solid wood.
If you plan to reduce costs, you can perform a typesetting-glue construction, making it from the edged remains of the timber. Most often in this case, a jumper and sidewalls from a solid array are used, while the window sill is made from a stacked beam. Install this design on a special profile. Its shape depends on what geometric configuration will be at the window or door. Specialists install casing in a wooden house in a variety of ways.
Most often they use cutting a special comb at the end of a window or doorway. A groove is also cut out on the mounted pigtail, thanks to which it is possible to secure it as firmly as possible, avoiding displacement and deformation. Among other things, this design will maximize the overall appearance of the house, as the openings will look much neater. In general, the casing of windows in a wooden house will not only make the whole building more beautiful, but also significantly extend the life of the PVC windows themselves, completely eliminating their deformation and warping.
It should be made only from a high-quality and well-dried wooden profile, since otherwise all your efforts will be meaningless. If you "lead" a poorly dried piglet, then the effect will be similar to the shrinkage of the whole house. It is also advisable to soak it with an antiseptic. The experience of builders shows that the casing in a wooden house in most cases is an absolutely necessary element that carries not only decorative, but also a functional load.
