Thanks for that, brilliant. I'm looking to roof a pergola and have taken some pointers from your video. Many thanks. Quick question though... could you have used wider sheets to cut down on the number of sheets such as the 1200mm (or even wider) you mention? 👍

@sunnysidenz 10 ай бұрын

Hi there, no worries :) Yes you can absolutely use wider sheets. I'd normally use 1220mm but I happened to have some 610mm that I needed to use. If you use 1220mm (or wider) you need rafters at around 600-650mm apart. So some of these will be in the middle of the sheet. In which case you use the Twinwall fasteners to fasten the sheet onto the rafter (drilling an expansion hole first). Hope that helps! Kurt.

A very useful video that will give me the confidence to replace my poly twinwall porch roof. The existing roof is 2m wide and 1m long with only outer supports. Do you think it would be better to add a middle support? Thanks again Colin

Glad it was helpful :) Yes you would need to add supports no further apart than 600mm (for 6mm Twinwall) or 800mm (for 8mm). Otherwise it will flex too much. Regards, Kurt.

Hi - I noticed you were kneeling on the panels. I was not aware they were strong enough to support a man’s weight. It won’t crush the channels in the panels to kneel on them while using the rubber mallet?

@sunnysidenz 4 ай бұрын

Hi there, good spotting. Ideally you wouldn't kneel on it, but because I've used it for some time I know how much weight I can put on it. Too much weight, especially on the point of the knee, and you will crush the channels. Best practice would be to use a drop sheet and plank on top if you need to put weight on it :)

Where did you put the screws into the roofing??? Everything I read says don't screw threw the H profiles.

@sunnysidenz 5 ай бұрын

Hi there, our H snap joiners are designed to be screwed through the bottom, into the rafter. Then you put the sheets on and then snap the top part of the H joiner on. If the sheets are 1200mm wide, they will also need to be screwed through the sheets into the rafter that goes under the middle of the sheet. More info here: twinwall.co.nz/ Thanks, Kurt.

Hi there, thanks for the vid, the spacings between the rafters you mention need to be 640mm, is this centre to centre, inside or outside dimension? Cheers

@sunnysidenz 5 ай бұрын

Hi there, no worries. It depends on the width of the sheet, and the inside width of the joiner. E.g. if your sheets are 610mm wide, and you allow a 30mm gap for the joiner, then you'd have 640mm spacings centre to centre. There's a diagram here that may help: sunnyside.co.nz/product/twinwall-polycarbonate-roofing/ Thanks, Kurt.

Great video! Where did you buy your twin wall polycarbonate sheeting from?

@sunnysidenz 4 ай бұрын

Thanks :) We actually supply the Twinwall, so if you're in New Zealand it can be purchased from sunnyside.co.nz. If you're not in New Zealand, if you search for Twinwall or Multiwall polycarbonate in your area you should find some suppliers. Thanks, Kurt.

How do you add long 3m C sections , wont slide on too much friction.

@sunnysidenz 9 күн бұрын

Yes, any longer than a metre or so can be difficult. Generally you should cut the U channel to the width of the sheet only. If you really want the full 3m length you could try levering them on with a long piece of aluminium. Or using a rubber mallet (and a block of wood) to slowly push them on. Hope that helps! Kurt.

I'm looking to replace a clear corrugated pvc roof. The timbers are already installed but not to vertically every 4ft however there are horizontal latts going across so can the multiwall just be fitted onto the latts?

@sunnysidenz 3 ай бұрын

Hi there. Yes, generally it can be fitted directly on to the horizontal purlins, as long as the joiners that you're using are suitable for that. It should show in the installation instructions for your system whether it's ok to only be supported on the purlins (depending on how far apart they are - usually around 800mm 32in or so). Thanks, Kurt.

Hi there, thanks for your message. I'm not sure I understand what you mean. Could you please clarify? Regards, Kurt.

Very helpful , just a question how did cover on the joiner for water, dust we don’t have to use tape ?

@sunnysidenz Ай бұрын

Hi there, generally you don't need to cover the ends of the joiners. However if the top end is exposed (e.g. not under a flashing) then you could put some sealant in there. Or if you're in a very dusty environment you could put sealant or tape on both ends of the joiner. Thanks, Kurt.
