The roof is the surface or roof covering the upper part of a building, mainly to protect the interior against weather and humidity. Thanks to our facade engineers who know how to perform a thermal balance and a BlowerDoor test, you can reduce the energy consumption of your building. They will make all the observations and analyses necessary to improve the energy performance of your building.

Of a basic form, the roof can be classified according to the type of substructure that will support the cover:

• Concrete
• Steel
• Wood

The developments in the field of glass currently allow to use of this material as a primary structure for buildings of high standing.

The skylights are light elements that are integrated into the roof and provide natural and zenith lighting for industrial and commercial buildings. They can, by crumbling, ensure the ventilation of all types of buildings and by opening 90 °, ensure access to the roof and the function of smoke evacuation outlet.
