Siderise Nexus Core offers both specifiers and manufacturers a firesafe insulation core with superb integrity, rigidity, flatness and in-built structural performance.
Siderise Nexus Core provides a fire-safe stone wool insulation core for composite structures such as architectural panels and doors.
Siderise Nexus Core provides a cost-effective pre-finished rigid core to be used wherever thermal, fire, and acoustic insulation is required within a bonded composite structure.
Siderise Nexus Core boards are produced using stone wool slab material which has been Euroclass rated A1 and is specifically formulated to a Siderise specification for use in this exacting application.
Stone wool is manufactured from volcanic rock which has been melted in a furnace to temperatures in excess of 1500°C. The molten product is then spun into a wool-like substance that has excellent fire, acoustic and thermal properties.
The unique Nexus process takes this insulating 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 which both maintains the compression and aids handleability.
The Core board should be bonded on the net face. Siderise maintains a close working partnership with major adhesive suppliers to ensure the compatibility of materials and attainment of optimum bond strengths.
