Polycarbonate Sheets longer than 3.6 m

Polycarbonate Sheets longer than 3.6 m

Need long polycarbonate sheeting?

Are you searching for profiled polycarbonate sheets longer than 3.6 m? Perhaps you need a twin-wall longer than 3.0 m?  We have long polycarbonate sheets. Almost all sheets are available up to a length of 7.2 m, others up to 9.0 or 9.6 m and some up to 11.98 m !!!

We regularly get calls from customers who are told at major chain hardware stores that polycarbonate roofing sheets are only available up to 3.0 m in length. This is simply not true!  This only reflects what they keep on their shelf!

It is always advisable, where possible, to have a single sheet along the fall of the roof. This means that the polycarbonate roof sheet is not joined along its length.  There a few reasons why this is advisable:

  • it keeps the sheet cleaner,
  • is easier to install,
  • is more economical,
  • makes it less likely that you will have a leak!

When you need to join

Finally, if it is necessary to join sheets lengthwise (this would normally only happen with a sheet run in excess of around 7-8 meters) it is important to consider a few things.

  • The join will need to occur over a support beam (purlin).
  • Each sheet should extend past the support (and screws) by a minimum of 100 mm, this will effective give a minimum 200 mm overlap as pictured below.
  • in some cases it may be advisable to use a sealing strip to ensure that no leaking occurs. This is mainly in low fall situations.
  • Joining twin-wall or multi-wall sheets (such as Sunlite, Makrolon, Sunpal, Danpalon etc) is not as easy!  Give us a call if you are considering this.

    Do you need to use silicon to seal between the joins?

      Hi Rick

      Generally using silicons on polycarbonate sheets is not recommended. Silicon can ‘stick’ the sheets together preventing expansion and contraction – which over time can damage the sheets. There are sealing tapes that can be used for this purpose if required. Try to keep a good fall, a good overlap and setting the sheets correctly help with any joint!

      Hope this helps

    Is there anywhere above the snow line where polycarbonate has been used in a ski lodge? If we were to think of using this material for an entrance area, how silly would we be? Can anyone name a lodge where this material has been used please?

    Cheers

      Hi Greg

      Polycarbonates are used all over the world – including cold climate (snow areas). Many sheet include info on snow loads. What sort of sheet are you thinking about and where are you located?

      Thanks Team PC

    I am replacing the roof on my greenhouse and need a polycarbonate roof that is suitable for growing orchids and ferns under. I can not find what light % the sheeting has. When asking suppliers they will not commit to what particular sheet of theirs is suitable.
    If I can just get a bit of guidance it would be great.

      Hi Helen
      Thanks for your enquiry. If you look at the brochure the light and heat transmissions are shown for each colour. I have attached the link for you.

      Generally the most popular colours for a greenhouse would be Clear, White Diffused or maybe Opal but you would need to work out how much light and heat you actually need.
      The style of greenhouse can also influence what you use – i.e. do you have vents that you can open in the hotter months to allow the build up of heat to escape.
      Other than that if you know other orchid growers you maybe able to see what they have used.
      Regards Team PCR
