Panels are insulated with 40kgs (other densities also possible ) of CFC free polyurethane of approved pre-mixed system, injected by a high pressure mixer, between cladding as per choice of customer and are locked securely together with camlocks with steel hooks.  The result is an extremely durable structure with high thermal insulation.

Camlocks are moulded and permanently anchored in the injected rigid CFC free polyurethane foam core during the manufacturing process of sandwich elements.  They are are tightly joined by a tongue and groove system into a monolithic assembly.  Assembly is performed from the interior simply by turning with a hex wrench the locking arm of the camlock in one panel, which engages the pin in the adjacent panel.  The camlock action drums the two panels tightly together.

The tongue and the groove edges assure positive alignments of all elements.  TSSC modular insulated rooms are easily added to at any future time or taken apart and reassembled in another location.
