N° H003 - Primary Fasteners (Note: All installations should comply with the recommendations contained in MCRMA Techinical Papers N° 12 & 14; BS3200 and other relevant national standards)

Primary cladding fasteners Self tapping and self drilling screws (galvanized carbon steel) with galvanized steel rectangularpressure plate washers.

Number and location offasteners

1 N° fastener at every support rail fixed through male extrusion plus intermediate fastenersas required by project specific calculations.

Fixing Cladding210G Structure Check that the structure is in a suitable state to receive the cladding before commencing fixing. Subcontractor must

confirm acceptance to main contractor.

215 Structure Do not fix cladding until final coats of paint have been applied to all contact surfaces of supporting structure, andremove all dust and foreign matter before finally fixing panels into position.

Drill all holes and install fasteners at regular intervals in straight lines, centered on support bearings.

Install fastners to correct tightness using special tools recommended by the fastener manufacturer. When used,screw guns must be fitted with depth sensitive devices and be used at the correct speed.

Check fasteners on completion and adjust as necessary to ensure that they are watertight and sheeting is securebut not buckled or distorted.

N° H014 - Fixing Generally (Note: All installations should comply with the recommendations contained in MCRMA Techinical Papers N° 12 & 14; BS3200 and other relevant national standards)

Accessories Matching flashings and support zeds.

410 Fixing Panels The use of Ondatherm sandwich panels requires accurate setting out, with due allowance for buildingexpansion devices (these must not be built over).

Before fitting the panels, the cladding contractor must inspect the supporting structure using thecriteria below listed, to ensure that the panels do not take on any uneveness inherent in the supportsupport system, thereby causing the finished surface of the facade to be out of true.

The results of a bilateral inspection by the principal contractor and the supplier of the support systemshould be duly recorded in any inspection report.

In case of complaint in respect of ArcelorMittal - Arval products we will require production of theinspection report for the support structure.

Any roof panel system is aesthetically only as good as the framework to which it is fixed. It isessential therefore that the support system is true to line and plumb. We recommend that allsecondary steelwork to which Ondatherm panels are fixed be designed to be capable of adjustmentduring erection. ArcelorMittal - Arval recommend steelwork tolerances as listed below:-

Vertical tolerance (full height of building) = 5mm maximumAlignment (adjacent vertical supports) = +/-2mmHorizontal tolerance (full length of building)

Ondatherm panels are purpose-made to specific requirements. Site cutting is not normally required,if cutting is required the following should be observed:-

Before cutting, masking tape must be laid on the cutting line to protect coating from damage.Cutting must be carried out with a jigsaw, blades are to have fine metal cutting serrations.Note - Angle grinders or similar type tools must not be used.

Cut panels on suitable supports to avoid de-lamination of metal skins by vibration.

All exposed foam cut panel edges to be protected afterwards with self adhesive foil tape. Cut openingsin panels for outlets, vent pipes, flues, etc. to the minimum size necessary. Reinforce edges of openingswith support angles/flashings.

Drill all holes and install fasteners perpendicular to the surface of the panels. Position the fasteners atregular intervals in straight lines, centred on the support bearings. Remove dust and any other foreignmatter before finally fixing panels into position.

Protect panels adequately during fixing and up to Completion against mechanical damage/disfigurement.Rectify any defects as quickly as practicable to minimise damage and nuisance. Cladding panels andflashings must be cleaned down and swarf, rivet mandrels, debris, etc. must be removed on a day to daybasis as work proceeds.

Paint all cut edges to match face finish.
