Dormer windows. Features, design, shapes

Some attic systems require regular airing and good lighting. This avoids dampness and air stagnation. To do this, when building roofs use dormer windows. They are placed on the slopes of the roofs at a distance of not less than 15 meters from each other so that the roof construction is more stable. Their number depends on the size of the roof and the wishes of the owners. If there is no electric lighting in the attic, the movement along it can be difficult, so having at least one window is mandatory.

Dormer windows have a design similar to a birdhouse. They have walls, a roof and a glazed part, they look very neat and pretty, representing together with the roof a single whole. Windows should be proportionate to the roof, as too bulky constructions will spoil the entire architectural ensemble or even create the danger of collapse of the floors.

Attic windows can be of several types. Most often they have a rectangular shape, they are made on roofs with two slopes or on flat roofs. In rare cases, the windows can be in the form of a semicircle or triangular, their manufacture requires experience and sufficient skill to prevent the passage of air or leaks during rains. Dormer windows of unusual shape look on the roof quite original.

If the attic space is conceived as a residential building, then it should be very well illuminated. The problem will be solved by additional bay windows. Their design allows several frames to be placed side by side. Such windows are characteristic for country mansions or for houses with non-classical layout. Their shape is also mostly rectangular, because such PVC profiles are easier to implement. But you can find windows of an oval or round shape.

When working independently on the manufacture of windows in the attic, it is important to carefully calculate the distance between them, based on their number. In the future, this will avoid problems with the installation of roofing. Another point - should be left a sufficient distance from the pediments, skate and cornices. These are the most important and important points when designing the layout of windows. Their form and complexity will depend on the functional purpose. Simple uncomplicated structures suitable for ventilation. You can actively apply and fantasy for the purpose of decorating the roof, but not at the expense of the direct tasks that the dormer windows should perform. That is, designs can be more complex and original, but with the preservation of direct lighting and ventilation functions.

To increase the efficiency of ventilation of attics, it is necessary to plan windows on both sides of the roof. The illumination depends on the dimensions of the glazed part of the structures. The width of the dormer windows should not exceed the distance between the rafters. This will avoid additional material costs and problems with fixing the structures. The roof covering is then simply installed between the windows.
