Prefabricated Panels, sandwich
type, available in standard, modular, lengths starting from
200 mm upto 1500 mm, heights range from 2000 mm to 6000 mm.
The panel consists of two outer skins with an inner insulated
centre made of self-extinguishing polyurethane resins complying
with ASTM D 1692/58 - DIN 4102B2 specifications, high insulation
coefficient (standard density : 40 Kg/cu.m.) and high pressure
injection techniques. Finishes : self-extinguishing fiberglass,
stainless steel AISI 304, galvanised plate, galvanised-prepainted
and galvanised-plasticised sheet metal. Panel's range of thicknesses
: from 60 mm to 200 mm.

Puf Panels
Prefabricated Panels in various
materials from pre-coated, G. I. S. S. either on both sides
or two different materials inside and outside are of Sandwich
type information and available in standard, modular lengths
to suit the requirement. The inner insulated center of the
sandwich panels is made of Polyurethane version suitable for
above use with average density of 40 Kg/M. The automatic foaming
machine regulates the volume and high pressure injection.
The polyurethane ( PUF ) in between the 2 skins. Panels range
of thickness from 60 mm to 200 mm.
The prefabricated panels can
be expanded to form required shape by connecting a male female
type of attachment implanted in the panels at site and further
made totally leak proof using fine spray polyurethane resins
at the site.
