Elasticity loss by a sealant of plastic windows – the typical reason of blowing off and a thinness of an antechurch. Such problems with a window arise, as a rule, for second or third operation (maybe earlier) if not to clean and to grease sealing rubber as that is demanded by the producer.
Drafts and catarrhal diseases are a far incomplete list of that discomfort which is delivered by "problem windows" with the grown old sealant. Replacement of a sealant by new will help to solve a problem.
4 main signs of need of replacement of a sealant
It is necessary to understand that not the sealant, and, for example, adjustment of a clip of a shutter of the PVC window is sometimes guilty, but nevertheless it is possible to specify 4 main signs of need of replacement of a sealant:
the expiration date expired — for a window sealant it is usually 5 years;
at the closed windows dust, noise from the street gets to the room, from a window blows;
visually wear tracks, cracks or production defects are defined;
emergence of frost, condensate or mold.
