NPS® Iso Beam

The self-bearing NPS® Iso Beam with expanded polystyrene footing (EPS) is patented for its optimal coupling with polystyrene ceilings. It maintains the thermoacoustic isolating advantages of this material, eliminating the risk of heat bridges between ceiling and beam, while guaranteeing lower surface in-plane.

The metal structure, made of structural steel (UNI EN 10025-2) is made of one or more truss welded using metal active gas welding (Process UNI EN ISO 4063-135) according to NTC 2008 in force.
Lower chords are inserted in precast class C28/35 concrete footing (UNI EN 206-1:2006), and equipped with reinforcement and surface reinforcement sized to support the heavy load of the ceiling on the NPS® Iso Beam. Two galvanised metal angular profiles positioned on the sides of the beam and partially encapsulated in cast concrete act as housing for the ceiling and guarantee the lower surface in-plane.

Product Details

Technical data

Metal structure Made of structural steel in conformity with UNI Standard UNI EN ISO 10025-2
Footing Made of expanded polystyrene footing (EPS) and concrete. Two galvanised side metal profiles partially encased in cast concrete act as housing for the ceiling and guarantee the lower surface in-plane.
Casting framework C25/30 when not otherwise noted by the designer
Self-supporting Yes. NPS® Iso Beam bears itself and the ceiling that rests on it, already from the moment it is placed on the column (1st phase), already before the formwork cast (2nd phase)
Welding Using metal active gas welding (Process UNI EN ISO 4063-135) according to NTC 2008 in force
Mechanical resistance to fire ( R ) No
Standards referenced In the 1st phase § 4.2 NTC 2008 and Eurocode 3 In the 2nd phase § 4.3 NTC 2008 and Eurocode 4 For anti-seismic § 7.6 NTC 2008 and Eurocode 8
Design Elaborated with the System calculation procedure conforming to the current Standard, and signed by a qualified technician.
Countable length Distance between theoretic supports used in the calculation
