When creating the aperture for your intumescent air transfer grille it should be noted that you will need to account for the 6mm hardwood liner that is recommended in most cases. This means you will need to add 12mm to each dimension to establish the size of the aperture. For example, a 300x300mm grille will need a 312x312mm aperture, and a 112x225mm grille will need a 124x237mm aperture.

Please note: First, check that your door is suitable for the fitting of an air transfer grille. If so, most doors will require the fitting of the hardwood liner. Your installer should be able to determine if the density of the core material is suitable that it does not need the hardwood liner - if in doubt, do fit the liner as per the instructions.
