Some issues keep recurring in our inbox, on flooring forums: cork strips among them.
A few days ago we received the following email:
"I realise the importance of leaving an expansion gap around a wooden floor (oak parquet in my case) but can you tell me why we are told to insert cork strips around the edge? Surely the cork is only taking up valuable expansion room. Is it ok to just leave a 10mm gap all around?"
This was our (recurring) answer on this subject:
Thank you for your question. We are trying so hard do tell everyone exactly that: DON'T use cork strips to fill the expansion gap.
These were used many, many years ago to divide design parquet pattern and the block border and somehow ended up in the expansion gap.
So, you are absolutely right. Leave your expansion gap 'empty' to cater for any natural seasonal movement of your wood floor."
Many thanks, it's nice to be right for once!
Of course he was right, we still don't understand how the old-fashion cork divider strip ended up as recommendation to fill your expansion gaps.
