FIXING RECOMMENDATIONS
Cooldek roong should be laid into the prevailing wind and sit neatly on the preceding roof sheet. For Classic prole fasten
through each crest and for CGI prole fasten through every second crest. Use cyclone caps and neoprene washers in all crest
xings. Fix side laps with 12x20 hex head screws with neoprene washers at approximately 1000mm centres, refer below.
The values in all the above tables are for use with steel supports with a minimum thickness of 1.0mm BMT, G550, or timber supports with fixing details as
specified below.
