Installation Instructions

SABIC Innovative Plastics 31
In semicircular barrel vaults both channel ends should
be sealed with perforated lter tape e.g. Multifoil AD
3400. See g. 22
Care should be taken to provide a clearance between
both the sheet edges and the sash platform to allow for
condensation drainage. See g. 23 and 24.
In general the total rebate depth for each prole should
include a minimum of 20 mm sheet edge engagement
and an allowance for thermal expansion.
25. Impermeable tape
on both sides
Specific Glazing Conditions
In certain environments, it is recommended that both
channel ends are sealed with an impermeable tape.
See g. 25.
These environments include:
• Extremely dusty environments (sawmills – welding-
stations, etc)
• Low humidity/dry conditions (shopping centres –
warehouses, etc)
• Limited temperature difference between the interior
and exterior (football stadia – metro/railway station
roong, etc)
