BNAL PUF sandwich panels are manufactured on a Cannon sandwich panel foaming plant imported from Italy. The PUF panels are manufactured using high quality two component CFC Free PU systems. Poly Urethane Foam Filled Sandwich Panels are used for providing thermal & sound insulation. These are light in weight & have good strength.
Insulated corner panels facilitate joint – less corners, Size 300 x 300 mm
Cam Lock Arrangement
Cam Lock Arrangement provides strong interlocking between ceiling, wall, door frame, floor corner and T panels, The cam lock provides perfect and strong alignment between the panel joints. There are spaced at equal distances along the perimeter of the panels foamed strongly into the panels.
Tongue and Groove
Another special feature of our panels is the tongue and groove joining arrangement. In this arrangement the panels are interlocked together by tongue and groove arrangement made in the outer skin of the panels. This arrangement is especially useful for panels which are less than 50 mm thick.
