Description
Metal -faced polyurethane sandwich panels are the system of choice today for large industrial buildings, refrigerated ware houses, office blocks, exhibition halls, fair pavilions, schools and sports halls.
The aluminium or steel facings themselves are surface coated and can be manufactured with profiles of various
depths leading to a higher load bearing.
Polyurethane sandwich panels come complete with specially formed tongue – and – groove joints ensuring a
perfect fit and maximum integrity. Assembly is fast, easy and cost effective.
The resultant sandwich panel has a load-dearing capability many times greater than that achieved by adding together the load-bearing capacities of the individual layers. As a result, these thin, relatively lightweight sandwich panels can safely bridgewide spans.
Puf insulated sandwich panels for roof and wall :
These panels functions well as a roof or wall panel when used in conjunction with pre-engineered buildings or
conventional steel framing systems. The product features an overlapping major rib at the panel sidelap, this sandwich panel is filled with CFC free polyurethane in the core achieving Good R- Values and consists of exterior and interior facings of relatively thin metal sheet profiled.
Panel strength will be more because of double sheet with corrugated profiles with core thickness varies from – 30 – 120 mm thickness. Purlin spacings will be upto 5 m so that steel structure cost in purlin will be saved.
