Ventilated Facade

Polyurethane rigid foam is an excellent insulation material, particularly well suited for applications requiring high mechanical properties. In the form of laminated boards, they are applied on roofs, ventilated facades, ventilated double walls, masonry construction, single-wall masonry interior walls, floors and ceilings and for floor heating systems. 

It should also be pointed out that the levels from ventilation noise in, for example, workshop premises are often lower than those emanating from other sources, for example machines of various kinds. It is not uncommon for the ventilation noise from industrial premises to cause more disturbance in adjacent offices than in the industrial premises themselves. The fact that ventilation noise propa gates in this manner is due to its pronounced low-frequency character. The more low-frequency components in the noise, the greater the propagation. Sound radiation from industrial premises, via duct openings in facades and roofs, may in this manner also cause disturbances in nearbv residential accommodations. 

Design of innovative natural ventilation systems such as systems with solar towers, glazed double facades, facades with passive shaft ventilation or with some means of heat recovery...
