Please note that the mountboard’s blackcore will change the surface colour to some extent – in comparison to whitecore.
Please note the colours shown here may be slightly different due to the limitation of colour rendition on device screens – if you require a mountboard swatch for an exact colour match please contact and we will send one out to you.
IMPORTANT transit damage to mountboard
We endeavour to pack mount board in a way that protects it during delivery to you. However, on occasions, a small amount of damage occurs to the board edges or corners. To prevent the need to replace damaged mountboard and the inconvenience it causes to you, we have reduced the price so it is equivalent to a board size that is 30mm smaller all the way around.
IMPORTANT delivery limitations
Please note, due to the size and nature of this product a packing/delivery surcharge of £ 8.00 inc VAT will be added to the delivery charge. Premium delivery is not available for this product. This does not apply to collections from our showroom.
