Windows is an essential part of any building, which is why keeping them as the first day is important.
This requires a good product at the time of installation and a good workforce. There are different types of window, but regardless of the nature of the window. There are two equal elements: the hole and the window, which must be joined. If this union is not done well, problems such as the tightness of the building, air leaks, loss of energy, or in some cases moisture stains and fungi may come.
Other effects can be seen related to the structure of the window, more specifically with the frame: a badly installed frame can suffer deformations and suppose an overload for the building.
