In this video we outline the steps involved when assembling a roof using multiwall polycarbonate sheets.
Access Plastics and 365plastics.ie, our online store, provide a Free cut to size service on all multiwall polycarbonate sheets.
We will not only cut the multiwall polycarbonate sheet to the required sizes, we also blow out the sheet to ensure that all plastic sawdust and plastic swarf is clear of the sheet. When that is completed we will apply a solid tape to one end of the sheet and a vented tape to the other end to protect the sheet. All our sheets arrive to you door, ready to be fitted.
In the above video, we explain the complete roofing assembly process, including placement of the roofing gasket and capping bar. The capping bar comes across the joint and the fixing screws, usually 60mm long, are placed into the pre-drilled holes.
For rafters where sheets are not been butted edge to edge, there is no need for a capping bar to be used, a simple use of a fixing button will cover the job.
It is important to use neutral curing silicone, as acetoxy silicone may attack the polycarbonate sheet.
When the sheeting is in position and the roofing is almost completed, it is necessary to achieve a water tight seal between the house wall and the multiwall polycarbonate sheet. This is achieved by using a butyl backed lead flashing, which is available in white and lead colour.

Just finished a roof today. Flashband was a pain to get joined accurately to 2 surfaces at the same time. I decided to cut the backing tape in half. Then i glued the top half to the wall. When this was done i then removed the backing tape from the bottom half and glued that down to the roof. I also cut the flashband into 1m lenghts to make it more manageable. Finally, i stuck a single length of narrower flashband overlapping the top of the supplied flashband. Now to see what happens when it rains.
Bit of feedback from fitting a roof today: it would have been extremely helpful if you’d said in the video to pre-drill the holes for the fixing buttons before fitting the solid and vented tape so the flutes could be hoovered or blown out: had just got two panels taped, end caps fitted, lifted up onto the rafters and drilling the first hole for a fixing button filled the flute with plastic swarf. Now considering whether to take it all down and strip the tape before pre-drilling or just have it look a mess.
Excellent presentation. Very well described. Thank you,
What about these on timber wall frame,how you join them together, these bars are for roof?
I wat to make double wall acrylic similar to double wall POLYCARBONATE sheets. Any idea if double wall acrylic with have a better insulation property's that the double wall polycarbonate ? I'm attempting to make a glass studio/office.
I found you video extremely helpful, however Its a shame you didn't go to greater detail in drilling the 18mm button hole, did you drill a pilot hole first? what type of drill to use? as making a mistake here becomes an expensive error. Could you give some more detail please.

when you drill the hole particles of polycarbonate gett into the flutes and is very difficult to remove.
What is the minimum pitch/slope that you recommend for multiwall poly-carbonate sheets?

Most of them require a minimum of 1/12, but you are better off with a minimum of 2/12. It also really depends on the thickness/strength of the sheets you are using. They can vary a lot, from 8mm two wall, to 32mm 7 wall as far as the snow loads they can carry.

Simply put it’s a 5-10degree slope, to facilitate rainwater run off and self cleaning.
What is a span with a4x8 sheet will it span 8 feet thanks
You didn't show how to get those confounded caps on the fixing buttons , darned near impossible to get some of those buttons into it's hole , if you had a bit longer length of plastic between the pull off cap and the button ,it would give us something to hold on to while tapping in the cap .
