Innodek composite decking boards are produced in batches and made from 60% recycled hardwood making this a natural product. For this reason slight colour variations may occur (most noticeable when purchasing uncapped boards in different lengths) so where possible we advise that customers purchase the correct amount on their initial order and in the same length to minimise the risk. Whilst we will always endeavour to combine all products from the same manufacturing batch this is not always possible when stocks are low or additional boards are added at a later date so on some occasions it may be necessary for us to combine deck boards from different manufacturing batches and in different lengths.
