Category guide
The sandwich panel joins two steel sheets to an insulating core in a single element that is roof covering, insulation and internal lining at the same time. Modeco supplies PU panels of 30 and 50 mm in RAL 7016 and the PIR panel of 80 mm, for the roofs and walls of halls, canopies, workshops and warehouses. The thickness is chosen according to the thermal calculation for the building.
The facings are continuously hot-dip galvanised steel sheet to EN 10346. The PIR core has a reaction to fire of B-s1, d0 to EN 13501-1 — low contribution to fire, little smoke, no flaming droplets; the thermal conductivity of the core is λ = 0.02 W/mK for PIR and about 0.022 W/mK for PU. For a particular panel the manufacturer's declaration of performance applies.
The panels are fixed through both facings into the substructure with screws with an EPDM sealing washer 6.3×19: GTR W 6.4/7.0 × 100–140 mm into timber, GT6 SP and GT12 SP 5.5/6.3 × 90–150 mm into steel. The screw length is the panel thickness plus the engagement in the substructure. The joints are sealed with butyl or vapour-barrier tape in the groove, because moisture passes through the joints and not through the panel; a roof panel is laid with the overlap of the upper sheet in the direction of flow.
Questions and answers
The PIR core has the better reaction to fire — class B-s1, d0 to EN 13501-1 (low contribution to fire, little smoke, no flaming droplets) — and a thermal conductivity of λ = 0.02 W/mK; the PU core has λ of about 0.022 W/mK and is used where the fire requirement is not decisive. Modeco supplies PU of 30 and 50 mm and PIR of 80 mm.
GTR W 6.4/7.0 × 100–140 mm for a timber substructure, GT6 SP and GT12 SP 5.5/6.3 × 90–150 mm for a steel one, always with an EPDM sealing washer 6.3×19 that seals the penetration through the upper sheet. The screw length is the panel thickness plus the engagement in the substructure — for a 80 mm panel into steel that is 90–150 mm depending on the profile.
PU of 30 and 50 mm and PIR of 80 mm. The thickness is not chosen from a catalogue but according to the thermal calculation for the building — a heated hall needs a thicker roof panel than an unheated canopy; the facings are sheet to EN 10346.
RAL 7016 (anthracite grey) for the PU panels of 30 and 50 mm. Other RAL shades are made to order with a longer lead time, because the panels are then produced specially; the facings are galvanised steel to EN 10346.
