WECU – WE CORK UNDERLAYMENTS
Read our new Choosing the Best Cork Underlayment blog article for help with selection!
For sound control and stress crack protection under ceramic tile, marble and hardwood floors.
WECU (pronounced “we see you”) is our economical and effective cork underlayment. We are proud of its flawless track record since its introduction in Florida in 1978 where tens of millions of square feet of WECU cork underlayment have been installed. A special preservative has been incorporated into the cork and binder mixture making WECU impenetrable to moisture. The density this process creates provides both effective sound control as well as stress crack protection. It is by far the most reliable cork underlayment on the market.
WECU is the economic and effective solution for sound control and stress crack prevention under ceramic tiles and hardwood floors.
Provides superior isolation of ceramic tile, marble and stone from existing and future stress cracks.
