They are obliged to produce all this as accurately as possible so as not to damage the walls or objects of the interior, if it is impossible to protect them in any way. After the double -glazed window is installed and thermal insulation is equipped. The second of these processes is to seal all the cracks between the wall and the installed window using mounting foam. When the latter freezes, slopes and window sills are installed. The host in all this process falls preliminary preparation of the premises and the removal of construction garbage. All the rest of the installers must do it themselves. This approach will allow you to get durable and well -functioning windows.
