We are looking for a reliable supplier of soundproof underlayment for 
engineered wood. The underlayment must be compatible to be glued to 
the sub floor (concrete) and engineered flooring to be glued on the 
underlayment. This is known as a double glue-down installation. 
It can be made of polyester fibers glued closely together with a 
thickness of 5mm. No film is needed to be glued on top of the 
underlayment because the engineered wood must be glued directly 
on the underlayment. Samples can be sent if the underlayment we are 
looking for is unclear. We are NOT looking for an underlayment for a 
floating installation. We are looking to become large distributors of 
this underlayment. 
Please set prices accordingly for many container orders
