Roof box
A roof box (technically: cornice box ) is a component on a house roof and is located under a roof overhang , so that the space between the house wall and the eaves is closed.
construction
Originally a roof box was made entirely of wood and was clad on the outer wall by boarding the rafters with tongue and groove boards.
Today plastic sheets or plastic boards are often used for the cladding. Since these have the advantage over wood that they do not rot and are lighter. However, plastics tend to become brittle when exposed to sunlight. With a roof box, there is sun protection when installed under a roof overhang.
If in the area of the roof box the design of the outer wall (e.g. with a clinker ) and the cladding on the underside of the roof surface are omitted, manufacturing costs can be saved.
purpose
A roof box leads to an optical rounding of the eaves or the roof and today offers space for lighting equipment around the house, since LED spotlights are cheap to get. At the same time, the facade and the roof structure are protected against wind and storms from below, as well as in the avoidance of the settlement of vermin under the roof overhang and additional insulation of the roof.
Living space for animals
Roof boxes do not provide space for their nests for various wall-breeding birds . For this reason, in the context of animal protection and conservation, some municipalities have switched to requesting replacement nesting boxes for heat-insulating renovations on the roof boxes of buildings . For non-insulated roof boxes for access is swifts and swallows recommended.
