Siderise NXS Nexus Fusion for Spandrel Panels - Fire, Acoustic and Thermal Boards
Verified by manufacturer 2 months ago
Siderise Nexus Fusion is a cost‑effective prefinished rigid insulation offering fire, thermal and acoustic performance for curtain walls, glazing systems and precast concrete cladding.
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 the technical datasheet for further information.
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 manufactured from stone wool slabs formulated to a Siderise specification for use in these applications.
The Nexus process involves cutting the stone wool material into strips and rotating them through 90 degrees so that the fibres are oriented perpendicular to the board surface.
The strips are then laterally compressed to form a more homogeneous board with increased rigidity compared with a standard stone wool slab of equivalent density. During compression, an open filament net facing is applied to one face to maintain compression and assist handling. The opposite face is aluminium foil.
Nexus Fusion boards should be bonded on the net‑faced side to glazing systems or mechanically fixed to precast concrete panels.
Siderise RFT 120/45 foil tape should be applied over all board butt joints on the foil facer. In glazing systems, the tape should be applied to all exposed edges of Nexus Fusion, lapping onto the foil facer and onto the substrate by a minimum of 10 mm.
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
- Provides an alternative to bespoke tray solutions and is intended to simplify installation.
