Common Corrapol®-BT questions:
How many fixings for a Corrapol®-BT sheet?
This is entirely up to the discretion of the installer as it depends on so many factors such as pitch, location, exposure etc. However, we suggest a minimum of twenty Corrapol® -BT fixings per sheet.
Is there a recommended purlin or rafter width for Corrapol®-BT Corrugated sheets?
Yes, this depends on a lot of factors such as pitch and location etc but please view our Corrapol®-BT Installation Guide for more detailed information!
What is the coverage width of a Corrapol®-BT sheet?
Each Corrapol®-BT corrugation is approx. 95mm peak to peak so depending on how many overlaps you are doing the sheet coverage is 835mm or 740mm for one or two overlaps per sheet, respectively.
What is the minimum pitch of Corrapol®-BT?
The Corrapol®-BT sheets themselves can be installed at any pitch from 0 degrees to vertical. However, due to the fact that the sheets overlap, we recommend a minimum pitch of between 5 degrees and 10 degrees is used to allow the water to run off depending on the location and application it is being used for. Remember the pitch of your roof will affect how much support is required so please see our Corrapol®-BT Installation Guide for more details.
