Heat-insulated sandwich panel with metal armament is the barrier coating element of the roofing and side walling of the hall, which have been used in the construction industry for over 40 years. This construction part between two steel armaments (corrugated steel plate) is filled with polyurethane foam of different thickness and mineral wool.
- prefabricated coating system
- meets stability, physical and fire protection requirements
- long life span
- fast assembly
Advantages of these panels in contrast to the sandwich coating used formerly, and assembled on the spot are the following:
- They are pre-manufactured in order to avoid any continuity defects of the coating.
- Heat insulation indicator is almost 100% instead of the former 67%.
- They are transported to the place of assembly pre-manufactured and cut in size, which significantly shortens coating.
The thermal transmittance factor helps to define that. Thermal transmittance factor is the rate of transfer of heat (in joules) through one square meter of both sides of the building material in 1 second in case of 1 K(C) temperature difference. Marking: u (formerly k)
THE LOWER THIS FACTOR IS, THE HIGHER THE INSULATING CAPACITY OF THE WALL IS.
