Pu Sandwich Panel Fire Resistance

Thanks to their properties the panels may be applied in object that require very high fire resistance pu sandwich panel is the most effective acoustic materials used on construction.

Pu sandwich panel fire resistance. The tests are based on. Fire resistant panel the fire class of a highly flammable substance polyurethane is b3. Therefore they can achieve different u values depending on the core and the thickness of the panel. As a result these thin relatively lightweight sandwich panels can safely bridge wide spans.

Pur b2 polyurethane b2 normally classed as b s3 d0. B1 and b2 grade pu panels are available for cold room. Take the 50 mm thick pu sandwich panel for example and the panel can absorb the sound over 30 db m2 widely used in the steel structure factory building activities room roof wall air clean room ceiling and partition. Fire resistant properties along with high insulation values offers a world of benefits compared with traditional pu panels.

Panels with a rigid polyurethane core also char in the event of a fire. Sandwich panels tenax with polyisocyanurate foam pir and polyurethane foam pur core are particularly suitable for the structures with very high thermal performance and fire safety requirements as well as for the structures with the risk of water condensation in the thermal insulation. Advantages of rigid polyurethane foam sandwich panels in factory and industrial buildings are. Pu panel is suitable for low and high temperature controlled applications like cold room and freezer room it has the characteristics of good thermal insulation low cold air leakage easy to transport and install lower running cost and higher fire resistance property.

Construction of industrial building using steel faced panels. Sandwich panels have λ values from 0 024 w m k for polyurethane to 0 05 w m k for mineral wool. The installation of a system with sandwich panels minimizes thermal bridges through the joints. The film summarizes the fire tests commissioned by if p c insurance and carried out in collaboration with several research institutes.

It also emits less heat and smoke. All the pu panels are connected by the easily operated built in cam lock. For example a panel just 100mm thick can easily bridge a clear span of some 6 metres. However the charred layer is not as strong as that in a pir or ipn core and it has a relatively low resistance to fire.
