Please note sheet sizes do vary so its better to have both the timber
joists and the roof sheets on site before starting work. You should fix
each joist after measuring the sheet you intend to use.
Step one
Fix your first edge bar as shown in diagram 1 slide the edge
fillet up the grove
on the bar as shown then cut the bar to length, remembering to allow for a
50MM
over hang into the guttering. Cut the aluminium base 2mm longer than the
intended
length of the polycarbonate sheeting, this will allow for the end cap to
be fitted later.
Drill and Fix the bar into position screw with no 6 screws at 3-400mm
centres
Ensuring the drip on the edge trim is in required place and neat from the
external view.
Repeat on opposite end diagram 1. Screws should be fix in the centre
section of the bar.
N.B Where bars are butting against wall the edge trim is not required
fit bar only.
Step two
You can either cut all sheets to evenly space them out or you can work
towards cut
a sheet in the middle, once you have decided start fixing centre bars, in
your required
position. drill and fix the bars with screws at 3-400mm centres
IMPORTANT REMEMBER TO LEAVE A CLEAR EXPANSION GAP OF 4MM
BETWEEN THE BAR AND THE POLYCARBONATE SHEETS.
Step three
Ensure all the rubber gaskets in the bars are flat with no bumps.
Step four
Cut your polycarbonate sheets the length if not already done ensuring that
all swarf is
removed use a vacuum or condensation free air line to remove swarf (never
try to wash it out).
Now fit anti dust tapes to the sheet use the solid foil tape to the top of
the sheet and
the vented tape to the bottom of the sheet peel of backing tape and stick
in place as
shown.
These tapes reduce condensation and keep out insects and dust so ensure
they are fitted
correctly Now peel about 50mm of the protective film down both sides and
place the sheet
in to place.
Step six
Position PVCU caps so that the toothed legs locate inside the centre of
the aluminium base
press down firmly then hammer down lightly with a rubber mallet or
equivalent until caps
lock down. As you work across the roof complete flashing as you go.
When the flashing is complete and all caps are in place remove
protective covering
Step 7
Fit the end caps into place. Now cut sheet closures to length between
bars and
push in to place as shown.
Tips
Cleaning only use mild soapy water try a small panel first to ensure there
is no reaction
never use solvent based cleaners.
You should not need to use silicone however if you do only use good
quality low modulus
neutral clear silicone.
For a good quality roof that will last the test of time avoid wide
sheets try to use
the recommended widths 1050mm in 16mm or for roofs over 4m long use 700mm
wide sheets.
Fix wall plates top and bottom fix joists as you fix polycarbonate bars
Use 9mm economy fascias all round and square white gutters for a
maintenance free finish.
