Polycarbonate Twinwall Roofing

PlacidCasual · 12 Jun 2017 at 21:48

Hi guys.

Does anyone have experience of twinwall polycarbonate roofing like Corotherm? I see it advertised as 900mm or 1050mm. Is this the distance between centres on the rails or the sheet width? I've looked for info but have drawn a blank.

If your wondering why I'm asking in a computer forum well I'm only registered here a beer form a sausage making forum and a woodworking forum and this forum is generally good at this stuff.

Any help much appreciated

It'll be the width of the sheet. The sheets come in many many different sizes.

Thx, still at a loss as to what the centre to centre distance will be as I've yet to find a good data sheet with this info. I'll try writing to a supplier.

Does it have a bba certificate? Usually have that kind of info on there...

I used it on my conservatory roof. I think I added 15mm gap between the sheets for the bar that goes between them, but as I found different bars have different sized gaps. Do you know what bar you want to use?

Not yet, I'm in process of designing my lean to workshop. I have a 4m by 6m pad but only intend to use 3m by 6m for the workshop. I need to buy some windows which will set my overall dimensions but I'm aiming for cheap miss measures or second hand units. I've been looking at Corotherm but I'm also looking for cheaper alternatives.

Our 'conservatory ' was really just a wooden frame with corotherm type panels for walls and the roof. Worked well as the panels let in lots of light. We only used it as a kids playroom and place to store their toys so weren't worried about security or properly heating it. Worked well though.
