Box and another box, according to the material it can be divided into: steel sub-box, aluminum sub-box, wooden sub-box and so on. In the new building, because the construction of the doors and windows of the building is completed, the size is not very standardized, the installation of sub-box, you can more accurately determine the size of doors and windows processing. Vice box on the doors and windows to play a role in positioning, positioning. In general, large projects require the installation of sub-box, so that the normative even stronger. Sub-box positioning, after installation, the doors and windows size and location to determine the wall surface structure of the treatment, and not to make the windows and doors of the surface damage or abrasions, played a role in protecting doors and windows.
In addition, it is also conducive to the installation of doors and windows, operability better. More conducive to the insulation of doors and windows and sealing performance, in particular, steel doors and windows due to thermal expansion and contraction caused by the expansion and contraction. So that the edge of the doors and windows to produce cracks, both affect its overall appearance, but also reduces the anti-seepage, energy saving, compression deformation of the functional requirements, so in the high doors and windows, the design and use of steel sub-frame structure, greatly improved doors and windows in these three A number of effective performance, improve the living environment of the safety and comfort. However, from the objective fact, the sub-box on the doors and windows of the seal, insulation, insulation and other aspects may not be good, especially the steel sub-box thermal conductivity stronger, if not handled properly, but easy to produce leakage, thermal conductivity Phenomenon, so in the zero single, retail doors and windows installed, the window box is not necessary.
