Q."Should carpet tiles be laid before or after partitioning has been installed ?" A. Installation is quicker and waste is kept to a minimum when carpet tiles are fitted before partitioning. However, carpets would need protection during the construction of the partitions and the tiles would be flattened along the lines of the partitioning if it was to be removed in the future. Jennor's preference is to lay carpet tiles after partitioning has been fitted. This is in order to minimise the risk of damage and ensure that a perfect finish is maintained onto which furniture can be installed.
