Application

Siderise Nexus Fusion boards provides a cost-effective prefinished rigid insulation with fire, thermal and acoustic properties for use in curtain wall, bespoke glazing systems and pre-cast concrete cladding systems.


Reaction to Fire – Nexus Fusion is classified as A1 to EN 13501-1 in mechanically fixed applications. Please see Table 1 for further information.


Table 1 : Reaction to Fire Performance


Classification Report; EUI-23-000506 


Thickness; Range 25-175mm 


Substrates; Mechanically fixed to gypsum or any other A1 or A2-s1,d0 substrate with a density of at least 525 kg/m³ 


Joints; Horizontal and Vertical with no gaps.


Air Gap; No air gap between product and substrate, with net facer tight to substrate.


For adhered applications, the reaction to fire performance for Nexus Fusion will be dependent on the type of adhesive chosen, the application weight of the adhesive and the reaction to fire of the substrate. Contact Technical Services for further information. 


Acoustic Performance


Siderise Nexus Fusion boards can offer additional acoustic absorption when incorporated into a façade build up.

 

Thermal Performance

For a given construction, the thermal resistance is determined by a combination of the grade of material and its thickness. The standard grade of Nexus Fusion has a nominal density of 77kg/m3 and a thermal conductivity of 0.038W/mK.

Description

Siderise Nexus Fusion boards are produced using stone wool slab material which has been specifically formulated to a Siderise specification for use in this exacting application.


The unique Nexus process takes this stone wool material which is then cut into strips and rotated through 90 degrees so the fibres are perpendicular to the board surface.


Additionally, the strips are subjected to lateral compression which eliminates any gaps and produces a more homogeneous board with a substantially better rigidity than a standard stone wool slab of the same density.

Whilst under compression the product is faced with an open filament net to one face which both maintains the compression and aids handleability. The opposite face is aluminium foil.


The Fusion board should be bonded on the net face to the glazing system or mechanically fixed to pre-cast concrete panels.

Siderise RFT 120/45 foil tape should be applied over all board butt joints on the foil facer. In glazing systems, Siderise RFT120/45 should be applied to all exposed edges of Nexus Fusion, lapping onto the foil facing and onto the substrate the Nexus is adhering to by a minimum of 10mm.


Siderise Nexus Fusion boards Features and benefits:

  • Classified as A1 to EN 13501-1 in mechanically fixed applications
  • Precision manufacturing and tight tolerances ensure that there are no gaps between boards, thus maintaining fire, thermal and acoustic performance
  • Removes the need for costly bespoke trays and the time-consuming process to install lightweight insulation
