WOOD & TILE FLOORING UNDERLAYMENT

Moisture control beneath wood flooring is critical to assuring a stable and proper installation.

The use of a vapor retarding layer underneath wood flooring provides a level moisture control in addition to noise suppression, adding value and longevity for any wood flooring installation.

Holland produces two vapor retarding paper products that are economical and feature rich: Blue Shield AS, and Blue Shield Grade 3030

The key functional characteristic for both products is the ability to provide a semi-permeable layer beneath a wood floor – allowing moisture to pass through at controlled rate. If moisture is not controlled beneath a wood floor, issues of warping, buckling and potential rotting of the sub floor are all possible issues that can be expensive to repair.
