Sometimes there are situations when plastic windows see through and let the cold through. In order to prevent drafts, you need to know some of the nuances. It happens that the windows begin to skip the cold from the moment of installation. In such cases, it is worth checking the quality of the window installation. Perhaps the master moved away from technology and made mistakes. Check how well the slopes are foamed. This is very easy to do if plastic slopes were used during installation. If everything is done correctly, then the slopes will be completely filled with foam. Secondly, it is worth checking if the veneered doors are blowing from under the opening. It is possible that the door was not properly adjusted during installation. This can cause cracks, which leads to drafts.
Also, if the window stood for several years and only then began to see through, then this: The foam with which the slopes were foamed dried up and turned into dust. It should be removed and the slopes filled with new foam. Sealing rubber bands wear out over time and lose their quality. Buy new rubber bands and replace the old ones with them. Check the structure for cracks along the window sill. If current are available, it is necessary to cover them with a solution, both from nutria and outside. There is also an option that the door is simply loose and needs to be adjusted.
