Alutech Dach – Insulated roof sandwich panel

ALUTECH DACH is a composite roofing panel composed of two metal sheet coverings connected by an insulating polyurethane layer . Panels can be installed on any type of bearing structure and in particular on metal structures. Superior sheet corrugation enhances load performances of ALUTECH DACH panels , which can be applied on big support dimensions.
