SANDWICH PANELS

 

Sandwich Panels are available in Aluminium and Steel profiles. These panels are specially designed for building requiring high insulation values. The factory injected insulation core with polyurethane gives excellent properties. MEI can provide a wide range of colors with reasonable period of time. A stock of fast moving color is available. Polyurethane insulation composed principally of the catalyzed products of polyisocyanate and polyhydroxyl closed-cell structure. It is used world wide as insulation against temperature extremes and has been adapted as one of the best energy material in the building industry.

 

Middle East Insulation manufactures roof and wall sandwich panels by use of PUR, PIR and Phenol with external and internal sheets of steel ALu Zinc or Aluminum of different thickness, coating and colors

Suitable for roof and wall of industrial, commercial and agricultural building

  • • Easy to handle
  • • panel with light weight
  • • can be used with large spans
  • • produce high insulation values due to its cell structure
  • • Ensure very low vapor permeability due to closed cells structure

Structure:

Free from CFC/HCFC mean no effect on Ozone Layer
