Fix your first edge bar as shown in dia 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 aluminum 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 Dia 1.
N.B Where bars are butting against wall the edge trim is not required fit bar only.
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.
Ensure all the rubber gaskets in the bars are flat with no bumps.
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.
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 (see tips).
When the flashing is complete and all caps are in place remove protective covering
Fit the end caps into place. Now cut sheet closures to length between bars and push in to place as shown
For polycarbonate cut to size order your polycarbonate sheets after you have fitted your bars and we can cut blow and tape your sheets for you to the correct size (width and length) NB do not forget to allow for expansion when ordering. (P.O.A)
If using a lead flashing ensure the lead (recommended) is fitted before the sheets and dress down as you fit the roof panels Fit your lead in sections of 2m and seal the over lap 100mm with lead mate.
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 980MM or less for roofs up to 4m long and 700mm wide for roofs 4m plus
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.
