Notes:    
General.

1.    LPCB Ref. No. 784b/01 & 784b/02  - Approved systems consist of Dryvit Genesis base coat, Dryvit Standard Plus reinforcing mesh, with or without Dryvit primer and a Dryvit Quarzputz PMRB, Sandpebble PMRB or Sandpebble Fine PMRB top coat, natural or tinted with a Qpcs value of up to 2.95MJ/kg.
    The stated EN 13501-1 classification is applicable to systems with a PMRB top coat, natural or tinted with a Qpcs value up to 2.63MJ/kg only.

2.    LPCB Ref. No. 784b/01 & 784b/02 - Any galvanised steel frame system, installed between floor slabs, confirmed by structural assessment to maintain the structural stability of the wall system in ambient conditions, and is suitable for the fire performance of the wall when exposed to fire within the building. The studs must have a minimum leg length of 45mm and be spaced at a maximum of 600mm centres (the stud size as tested was 100mm x 45mm x 1.2mm). The frame shall be clad with any sheathing board system suitable for the application on the external (cladding) face of the following generic types:- cement particle board (min. 12mm thick), cement-based calcium silicate board (min. 9mm thick), calcium silicate board (min. 9mm thick) or magnesium oxide board (min. 9mm thick). The system is approved with or without mineral wool insulation within the steel frame stud cavity. The internal face frame shall be clad with any type of gypsum wallboard that ensures that the required reaction-to-fire and fire resistance performance is provided when the wall is exposed to fire within the building.

3.    Subject to the stated conditions the Outsulation & Outsulation Plus systems (LPCB Ref. No. 784b/01) shall be installed in accordance with the application detail contained within Dryvit documents DUK204 (21/01/08) and DUK218 (V1 21-2-07) respectively. The Outsulation Rail system (LPCB Ref. No. 784b/02) shall be installed in accordance with the application detail contained within Dryvit document DUK664 (21-08-07).

4.    The system is approved with or without horizontal expansion joints in the render and insulation layer.

5.    Dryvit EPS insulation boards adhered to the sheathing board with Dryvit Genesis adhesive.

6.    Minimum 100mm high continuous horizontal lamella fire breaks shall be affixed direct to the sheathing board with continuous band of Dryvit Genesis adhesive. The fire breaks shall be positioned at a maximum of 870mm above openings and a maximum of 3100mm centres between consecutive breaks.

7.    The system is approved with or without horizontal expansion joints in the render and insulation layer.

8.    Dryvit EPS insulation boards fixed to a mechanical PVC 'T' spline railing system. The rails are fixed to the sheathing board using packing shims of up to 15mm thick at 300mm centres with suitable fixings to form the drainage cavity.

9.    The cavity fire break system and continuous horizontal lamella fire breaks shall be positioned a maximum of 800mm above openings, subsequent fire breaks shall be positioned at each floor slab at a maximum spacing of 3100mm centres.
