What type of plyboard should I use on GRP Roofing? As per the title, what type of plyboard should I use with fibreglass roofing?
We would recommend that you use 18mm tongue and grooved OSB 3 sterling board for your fresh roof deck. The tongue and groove will make it easier to install and you will not have to reinforce the seams with roofing resin and glassfibre. For more information on what types of decking to use with fibreglass roofing, check out our guide . Hope this helps. If you have any more questions, please give us a call.
