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.

These paper control moisture flow mitigating against warping, buckling and sub-floor degradation.



Proper underlayment allows for a slip layer in between the flooring and the sub floor reducing squeaks.

Vapor retarder is a layer that allows moisture to cross it’s interface at a controlled rate. This metered amount of moisture introduction allows for opposing sides of the retarding layer to equalize over time.

A: Vapor retarders are used beneath wood flooring to slow the introduction of moisture that could buckle or warp the flooring.  Additionally, the retarder allows moisture to escape the sub floor to avoid the moisture being trapped and leaded to rot.

Grade D papers are characterized as single ply and the asphalt material is saturated on both sides of the paper.  Grade B papers are laminated with a continuous layer of asphalt therefore the product is paper on both sides.  A Grade B Paper is considered to be a superior retarding layer.

Holland’s wood flooring underlayment papers are easy to install.  The paper is rolled out and overlapped with next layer by approximately 4 Inches.  Cover the floor in its entirety making sure the sub floor in clean of debris and protrusions prior to underlayment installation.  There is no need to secure the underlayment paper to the subfloor, the paper should be allowed to “float”.
