The nail-down flooring should be nailed to a further subfloor layer. The subfloor layer should be thick sufficient in order that nails will not protrude. The Iso-Move® flooring underlayment would reside below this layer, free of charge from any penetrating nails. Ideally, we'd use a material with 5kg/m2 and 10kg/m2. https://motherw371gmh0.blogdosaga.com/profile
