RigidRAP

Why wrap your house with a piece of paper when you can build so much better with IBS RigidRAP. Better bracing, air control, moisture control and you can work inside the house during construction which speeds up your move in date.

IBS RigidRAP® is an 8mm OSB3 product that has been laminated with an approved building paper to give your house dual protection from the weather during your building process.

How to install RigidRAP?

You can download the installation guide on this page.

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.

How do I join at mid-floors?

You must use a Z flashing if joining RigidRAP at mid floor level. For all other horizontal joins we recommend 150mm flashing tape.

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 be left before cladding?

You can leave outside in the weather for up to 90 days before cladding.

Can I direct fix to RigidRAP?

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 on steel frames?

No, but you can use IBS RigidRAP-XT. Full details are on our website.

What certification does RigidRAP have?

IBS RigidRAP has Codemark certification.
