Roofs: closing the building from above

The roof is the largest single surface of most industrial buildings, and it is also the surface most exposed to weather. A metal roofing system is planned as part of the envelope, together with drainage, roof penetrations and the way the roof meets the wall at the eaves.

Roof inquiries should describe the roof plan, the drainage direction, and every penetration or roof-mounted item separately. If the roof will also carry a photovoltaic array, say so at the start, because a roof that carries solar equipment is planned differently from a roof that only has to close the building.

Metal panels within the envelope

Metal panels are one element inside the envelope system. They form the wall and roof surfaces, and they are chosen together with the frame, the fixings and the junction details. A panel description on its own does not describe a building, and this site does not present panels as standalone products with published specifications.

If your inquiry concerns panels, describe where each panel type is used, which surface it closes, and what it must join to at its edges. That is the information a manufacturer needs in order to confirm scope, and it is the information this site asks you to prepare before you send an inquiry.
