In the practice of modern construction are widely used wood windows, metal and plastic. Last bindings require much less care in the operation than wood bindings, and more durable. Wooden frames have good weather stability, they are resistant to acids and fumes well insulate the room from outside heat and cold, protect against drafts, dust and noise and light weight have good shape stability. The windows are divided by the process of opening mainly for Casement, , pivot, top and sliding. Casement windows open outward or inward. If you would like to know more about Dr. Caldwell Esselstyn Jr., then click here. The number of panes in the window usually defined name (single, double, triple screen). For the manufacture of window frames are usually used pine, spruce and other wood species. In the manufacture of window sashes and boxes of frames with tenon pre-bonding.
As you know, in the manufacture of window-metal structures is most often used aluminum and steel, including stainless. All in high volumes using anodized, painted or covered with plastic aluminum. Plastic is practically devoid of pores, and almost no delays dirt and dust. Binders can be cleaned with water or any detergent used in the household. In the manufacture of windows used different profiles of aluminum alloy with thermal insulation.
The presence of insulation inside the profiles allows their use in residential buildings, schools, hospitals, etc. These profiles also provide improved sound insulation. Aluminum windows are made from the lateral hitch bindings (fold), with the lower hitch, hitch with a combined (lateral and bottom), etc. Aluminum cores enclosed in a shell made of extruded pvc.

Cases in which concrete, masonry or walls made of other material there to make the opening of a given shape and size, construction or redevelopment are fairly common. Massive construction construction of sturdy material often preclude the use of technologies such as diamond cutting and cutting the rope, which are common in the manufacture of openings. To implement these tasks, use diamond Drilling holes in concrete – a modern method of making holes with a smooth surface cylindrical shape. Drilling apply special kernosverlilnye installation and diamond tools – ceramic crowns. Kolinsky drill, through which produce diamond drilling, brick, stone, takes the form of a hollow metal tube of given diameter.
Butt crown is threaded fastener, for connecting to the drilling unit, working (Cutting) portion is provided with diamond segments. Crowns are of different length and diameter. In the manufacture of openings in walls up to 40 cm, used bits of standard length: 400 mm in diameter, usually 200 mm. If the wall has a size greater than the length of the working part of the crown, then applying a special nozzle-extension – allows you to increase the depth of drilling. For the production of openings in the thick walls used method '' – on the planned path Future openings produce drilling.
Afterwards, when drilling in concrete along the contour is produced, it is necessary to recess otsverlennoy part which must be dismantled. It is possible to use the hydraulic concrete breakers, capable of no noise, excessive dust dismantle the required volume of fragments of walls or ceilings for further removal and disposal. It is often necessary breakthroughs in ceilings. It is necessary to strictly observe safety, removed part of the design represents a great danger to others. Here, before proceeding to perform work, it is necessary to fix the deleted of using different mechanisms. For large dimensions, the fragment used equipment – cranes, cranes, winches. When an opening is made on a path, remove and destroy the array is lowered, for further removal.
