Which way do the sheets need to be installed?
All sheets should be installed vertically for bracing. Sheets can be installed horizontally if they are not used as a bracing panel.

How much gap do I need to leave between sheets?
You need to leave a 2mm gap around all sides of the sheets for expansion and contraction. This means 4mm between the sheets on all sides. Hence the sheet width of 1196mm.

What tapes do I use?
A list of all tapes that have been tested and approved is listed in our Installation Guide. All tape installation should be in accordance with the manufactures install details.

What is the nailing pattern on the sheets?
150 centres around the perimeter of the sheets and 300mm through the centres. 75mm centres on the top and bottom plate. If not used as bracing 300mm centres.

How long can the RigidRAP-XT be left before cladding?
You can leave outside in the weather for up to 90 days before cladding.

Can I direct fix to RigidRAP-XT?
Corrugated iron is the only product than can be directly fixed as this profile forms a cavity type system. Corrugated iron needs to be installed vertically when fixing directly. All other cladding products need to be fixed to a cavity system.

Can I use RigidRAP-XT on timber frames?
Yes you can, although no bracing tests have been done with timber frames. You could use as a wrap only.

What certification does RigidRAP-XT have?
IBS RigidRAP has Codemark certification.
