Laminate flooring finish - 
If you are using laminate flooring, we recommend placing a solid layer on top of the SFUF ( such as plywood layer).  Proceed to install your laminate flooring as per manufacturers recommendations.

Proceed to lay your underlay directly on top of the SFUF, and finish the installation by laying carpet as per manufacturers instruction.
