As with other questions about the configuration of PVC structures, it is impossible to unequivocally answer the question of which windows are better to choose for a cottage. The optimal configuration depends on the features of the building in which the structure will be installed, the size of the opening, functional requirements, etc.
The question of why it blows out of the window is asked very often. If you ignore the problem of drafts, then heat losses will increase — and very soon, even at not the lowest temperature outside, the owner of the room will feel severe discomfort from the cold.
One of the advantages of modern metal-plastic windows is that they can be completed taking into account the needs of the owner. This applies primarily to the hardware mechanism — the hardware can not only open and close the sash, but also perform other functions.
