The standard size for external sheathing boards is 1200mm x 2400mm. This equates to 2.88 SQM so you can work out how many boards you need for your project by dividing the SQM of your project by 2.88. We recommend adding at least 10% to cover cuts, breakages and wastage.

If you are using Klasse sheathing boards for internal applications then the board edges can be tape and jointed similar to using a standard gypsum plasterboard.

Usually Klasse sheathing boards are used in external systems and to increase fire resistance we recommend sealing all joints with Klasse FIREFEND FR Silicone Sealant.

Put simply, for indoor applications - yes.

All Klasse external sheathing boards are Euroclass A1 Fire rated meaning they are fully non-combustible materials.
