I had to replace the floor tiles in my conservatory and decided to buy Distinctive Flooring Ribbed Carpet Tiles Sapphire from Screwfix. I laid them using double sided tape and was happy with them. After a few months gaps started to appear between the tiles which steadily got worse. I tried to contact Screwfix and eventually got a response via their web site. The came back saying that these tiles had to be glued down and they arranged to supply a another box of tiles to allow me to refit them to remove the gaps. When the new box arrived I found that there were no instructions to state they had to be glued. There is no information stating this on either the Screwfix or the manufacturers web site. To make matters worse I found that the tiles beneath the two sofas had not shrunk making relaying them a disaster as they wouldn’t line up. Be warned do not contemplate buying these tiles.
