Installation Guide

Step one 

Fix your first edge bar as shown in Dia. 1. Slide the edge fillet up the groove on the bar as shown, then cut the bar to length, remembering to allow for a 50 mm overhang into the guttering. Cut the aluminium base 2 mm longer than the predetermined length of the polycarbonate sheeting, allowing for the end cap to fit later.
Drill and fix the bar into position, screw with no six screws at 3-400 mm centres, ensuring the drip on the edge trim is in the required place and neat from the external view. Repeat on opposite end Dia 1.
N.B. Where bars are butting against a wall, the edge trim is not required; fit the bar.

Step two 

You can choose to cut all sheets and then evenly space them out, or you can work toward cutting a sheet in half. Oncee you have decide,d start fixing centre bar, in your required position.Drill and fix the bars with screws at 3- 400 mm 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 sheet to he length if not already done, ensuring that all swarf is removed. Use a vacuum or a condensation-free airline to remove swarf (never try to wash it out). Now fit anti-dust tapes to the sheet. Use the solid foil tape on the top of the sheet and the vented tape on the bottom of the sheet. Peellofff the backing tape and stick in place as shown. These tapes reduce condensation and keep out insects and dust, so ensure they fit correctly. Now peel about 50 mm of the protective film down both sides and place the sheen in position.

Step Five
Position PVCU caps so that the toothed legs locate inside the centre of the aluminium base. Press down firmly, then hammer down lightly with your rubber mallet or equivalent until locked down. As you work across the roof, complete the lashing as you go (see tips).
When the flashing is complete and all caps are in place, remove the protective covering.

Step Six
Fit the end caps into place. Now, cut sheet closures to the length between bars and push them in place as shown.

Tips

For polycarbonate cut-to-size orders, please order your polycarbonate sheets after you have fitted your bars. We can then cut and tape your sheets to the correct size (width and length). Note that you should allow for expansion when ordering. (P.O.A)
If using lead flashing, ensure the lead (recommended) is fitted before the sheets and dress down as you install the roof panel. It's your lead in sections of 2m and seal the overlap with a lead mat, 100 mm.

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, if you do use it, 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 of 980 mm or less for roofs up to 4m long and 700mm wide for roofs longer than 4m.
Fix the wall plates, both top and bottom, and secure the joists as you install the polycarbonate bars.
Use 9mm economy fascias all round and square white gutters for a maintenance-free finish.
