Installation Guide
Please note that sheets vary in size by up to 10mm. Do not install your roof timbers until you have the sheets on site to measure them as you go.
Step one
Fix your first edge bar, as shown in this one. Slide the edge fillet up the grove on the bar as shown, then cut the bar to length, remembering to allow for a 50MM overhang into the guttering. Cut the aluminium base 2MM longer than the predetermined length of the polycarbonate sheeting, enabling the end cap to fit later.
Drill and Fix the bar into position screw with no six screws at 3-400MM centres, Ensuring the drip on the edge trim is in the required place and neat from the external view. Repeat on the opposite end, Dia 1.
N.B. Where bars are butting against a wall, the edge trim is not required to fit only the bar.
Step two
You can cut all sheets and then evenly space them out, or you can work towards cutting a sheet in the middle once you have decided to 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 are removed. Use a vacuum or condensation-free airline to remove the 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. Peel the backing tape and stick it in place as shown. These tapes reduce condensation and keep out insects and dust, so ensure they fit correctly. Now peel about 50MM of the protective film down both sides and place the sheet into place.
Step Five
Position PVCU caps so that the toothed legs are inside the centre of the aluminium base. Press down firmly, then hammer down lightly with a rubber mallet or equivalent until the caps lock down. As you work across the roof, complete flashing as you go (see tips).
Remove the protective covering when the flashing is complete and all caps are in place.
Step Six
Fit the end caps into place. Now, cut sheet closures to the length between bars and push them into place as shown.
Tips
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 does 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 dressed down as you install the roof panels. Fit your lead in sections of 2m and seal the overlap 100mm with a lead mate.
Cleaning: 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, only use good quality modulus-neutral clear silicone if you do.
For a good quality roof that will last time, avoid wide sheets and 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, and fix joists as you fix polycarbonate bars
Use 9mm economy fascias all around and square white gutters for a maintenance-free finish.
