Be about winter, cold wind infuse, how does window leak wind to do?Actually door window leaks wind is sealed thing not only, have very big knowledge among them.
Doors and Windows profile, production technology
Windows and doors is the relationship between air leakage and the material is very big, if the material is bad, the compressive strength is no door window frame, don't test, big wind and rain with a two or three years may occur deformation, once the deformation, cracks may appear between frame and glass, sealed performance is poor, and air leakage, into a series of problems, such as dust and blowing the longer, the larger the aperture, open the floodgates... from now on
So, when we are window of window of choose and buy, should notice door window material to pledge and make craft all the more.Want to avoid choose and buy to be made by the door window of manufacturer of a few inferior profile or without any qualification safeguard.
Doors and Windows installation
Installation also is the main factor that decides whether door window is sealed, even if have high grade door window, installation is not in place also can affect door window sealing performance badly.
Above all, door window must be an zheng, the likelihood after door window USES period of time otherwise can appear door window more and more slanting circumstance, the aperture between window frame and wall body also can be bigger and bigger, leak wind is unavoidable.Next, when door window is installing, need makes foaming gum to fill the aperture between window frame and wall.Wait for hair bubble gum to solidify hind, wipe on sealant equably on the periphery of window frame again, prevent rainwater to seep into indoor from the installation aperture of window and wall body already, also prevent leak wind.
It is important to note that the Windows need to be in the internal and external double-sided sizing, if in order to save time or cost, only in the internal glue, or in the internal point of a few glue, will lead to the Windows and doors leakage phenomenon.
Door and window seal
Sealing strip is a common problem of aging cracking, if there are signs of hardening, can be addressed from the following aspects.
It is to look for door window manufacturer, seek advice whether to need to change;If so, contact a professional to replace it.The 2nd it is him to change sealing strip, vitreous sealing strip is to insert the card slot on vitreous edge inside, when changing, need to pick out with screwdriver only draw out, insert new sealing strip again go in and knock tight can.
Hardware for doors and Windows
Hardware fittings is the product that the activity in door window is frequent, be worn easily, if do not have high quality hardware fittings, door window performance also can discount greatly.
Specifically, hardware accessories and lock lock distribution around the doors and Windows, when the door lock, lock, lock button firmly together, cooperate with hinge (hinge) or friction, common produce strong sealing clamp force, make the sealing strip elastic deformation, thus providing enough for doors and Windows sealed performance, make the fan, box to form an organic whole, and thus improve the sealing performance.If hardware fittings is inferior, door window quality is again good, its heat preservation, heat insulation sex also does not have which go.
