FAQ for HardieTex™ system

What is used for external corners when using HardieTex™?

We recommend the HardiTex® External Corner Angle. It has a 2mm ridge for the texture coater to screed off to for a clean finish.

Why doesn't a HardieTex™ sheet have 4 recessed edges?

Sheets are installed vertically in walls exceeding 1200mm high.

What are the advantages for using HardiTex™ sheet rather than rendered bricks?

HardiTex® base sheets  are quick and easy to install enabling the interior to be started sooner and reducing construction time.Due to the lightweight construction it has greater design capabilities and savings can be made with the size of the footings required. HardiTex® can be used as the external cladding of a fire rated wall system.It will also product a smaller footprint.

How do you get a recess on the non-recessed edge of a HardiTex™ sheet?

Use an angle grinder fitted with a masonry or diamond blade and a dust collection device to form a recess as shown in the HardiTex™ fixing manual. Hitachi have an "Easy Bevel" attachment to suit an angle grinder.

Why doesn't a HardieTex™ sheet have 4 recessed edges?

As sheets are usually installed vertically there is no need to provide a recessed edge at the base. It also allows sheets to be cut to size without wasting the recessed edge.

 I have commercial type framing, and I wish to install HardeiTex™ as a facia. Is this feasible?

No, use ComTex® facade panel and fixing system for commercial type framing. Please refer to the technical manual for further information.

Can HardieTex™ sheet be attached to a galvanised iron external fence or any other existing fence?

No, there will be too much movement and cracking will occur at the sheet joints.

Can HardieTex™ be used a bracing?

Yes, HardiTex™ base sheets can be used to brace a wall frame. Please refer to the structural design manual for further details.
