Sandwich Puf Wall Panels
Cladding manufacture PUF sandwich panel for wall & ceiling panel.
The raw material used for manufacturing PUF panel is CFC free and fire retarded grade. Panels are provided with Tongue & Grove joints and specially designed Cam locks to enhance airtight assembly. PUF Sandwich panels are available with pre coated GI sheets, SS sheets or as directed.
The standard density is 40 Kg. ± 2 Kg. m3. Also available in different density.
The top and bottom coil (sheet metal) are clamped onto the plants unwinding unit and fed into the machine. In the first step, “corona system” cleans both reverse sides of the sheet metal using high frequency to remove greases and dirt and to guarantee the best possible subsequent full spread adhesion between foam and sheet metal. Thereafter the protective films are rolled onto outside of both metal sheets. The sheets are then brought together, the bottom sheet is foamed by the swinging foam head and the top sheet is mechanically steadied. Immediately thereafter, the panel is fed continuous line into the heated drying tunnel where the foam expands to its full volume, binds to the sheets and transforms both sheets to one robust, shear resistant composite structural panel. After leaving the tunnel the panels are cut according to your specification using flying saw/cutter.

Energy efficiency
with 80 mm thick sandwich panels with polyurethane rigid foam, the U value is 0.297 W/(m K).In comparison, asolid wall with 24 cm thick masonry and 2 cm plaster walls has a U value of 1.85 W/(m K).
Rigid polyurethane foam combines excellent thermal insulation properties with good mechanical strength,making it an outstanding construction material that does not rot,mold-resistant,odorless and non-toxic for all conceivable applications,The foam is resistant to the chemicals typically used in construction and is compatible with most solvent-containing adhesives,paints and wood preservatives.
polyurethane rigid foam is extremely durable and can be installed easily and securely,ensuring cost-effective,efficient construction.
Sandwich Wall Panels Concelead Fastening System
Sandwich PUF panel with a concealed-fixing method for high quality industrial and commercial buildings, where good aesthetics are paramount. The special double labyrinth joint of this panel, provides mechanical resistance and insulation superior to any other wall panel product of this kind. The panel external micro-V increases the aesthetic appeal of this panel, which can be orientated both vertically and horizontally as required.
If wind pressure on a wall sandwich panel is more than allowed limit of panels so it is needed to fix the sandwich panels with self-drilling screws on a metal net. On the ordinary panels these screws are visible but hidden screw wall panel are designed so that the drilling screw are operated under the notch and tab and cause tight and firm connection. Cladding hidden screw wall panels can be manufactured with various patterns and designed like fine, corrugated coarse corrugated. Beside the designs Cladding is presenting the hidden screw wall panel with water fall design to the market that has great insulator and firmness and can be assembled horizontally and vertically as well.
