Fixing
Instructions
Sheets
must not be stacked in direct sunlight or
distortion and discolouration will occur, due
to the serveral thicknesses acting as a magnifying
glass and causing heat build up within the stack.
If left in the open, sheets should be covered
with an opaque(not black) tarpaulin. Stack height
should not exceed 1.22m(4'0") and should be
supported on 2" battens, not more than 3' apart.
Cut
sheets singly or several together over a firm
support. Use a fine tooth saw at a low angle.
If 'binding' occurs the saw can be lubricated.
Care should be taken in handling and cutting
in very cold weather. Extreme caution is recommended
at temps below 4.5degrees Centigrade(40 Fahrenheit).
Drill sheets singly or several together, preferably
over a firm support using a hand or slow speed
power drill and a masonry bit. Holes should
be 2mm(1/16") oversize the fixing screw or bolt.
Never punch holes through the sheets;all holes
must be pre-drilled prior to nailing. Always
use Ariel fixings comprising screws, washers,
caps and for better support use Ariel Super
Fixings(See profile diagram and Purlin Centres).
When lapping ends of sheets the minimum lap
should be 150mm (6"). But where the roof slope
is less than a 10 degree a 12" overlap is recommended.
Never leave inadequately fixed sheets on unfinished
jobs. Fixings should not be overtightened and
no nearer ends of sheets than 50mm(2"). A false
ceiling must not be erected below the Vistalux
as this will cause heat to build up which will
discolour or distort trhe Vistalux sheet.
Wind
Loading. Where sheets are to be used on
buildings subject to high wind loadings, or
other unusual conditions, please refer to the
technical advisors.
Flashing.
Where Vistalux sheet meet a wall, the gap
should be sealed wiht Clear PVC flashing and
flat aluminium flashing or rpeformed aluminium
flashing.
