Sandwich Panels PUF, PIR, Rockwool

Rigid polyurethane foam, sandwiched by metal or flexible facings, is increasingly successful in meeting the requirements of the construction industry, emphasizing on cost effective system building and energy conversation. Their specific file of application covers the construction of industrial and commercial buildings, ware houses and cold storages, refrigerated transportation).

Polyurethanes are three dimensionally networked macro cellular thermosets as a result of a reaction between a multifunctional polyol and a multifunctional isocyamnate/MDI in the presence of a blowing agent and additives. Apt metals can supply sandwich panels in various thickness (35mm to 100mm), various facing combinations of pre painted steel and aluminium in thickness ranging from 0.25mm to 1.0mm and in different colors.
