EnStron Underlayment

For years, builders have settled for underlayment products like Lauan plywood which are produced in a layering process and more susceptible to delamination and voids making them not ideally suited for usage as an underlayment. Products like vinyl floor coverings require a smooth, consistent surface. EnStron underlayment from Plummer Forest Products fulfills this need and more. EnStron is a composite underlayment panel engineered with a smooth surface and a density 50% greater than Lauan plywood.   

EnStron is made with a no added formaldehyde (NAF) process using recycled quality pine and northwest white wood fibers which do not have natural acids like Lauan plywood.  These acids cause bleed-through and staining of vinyl floor coverings.  EnStron is the most environmentally friendly underlayment choice available.


EnStron Underlayment Plus

Formaldehyde-Free EnStron Underlayment Plus is simply the best Choice for resilient floor underlayment. Products like vinyl floor coverings require a smooth, consistent surface. EnStron Underlayment Plus is a particleboard underlayment panel which was engineered from scratch. Customers desired a panel with higher density, and a smooth, consistent surface. The board needed to eliminate delaminating and color bleeding, issues commonly found with other underlayment products. Plummer exceeded those expectations. We engineered it with recycled wood fiber and no added formaldehyde (NAF), making it the most environmentally friendly underlayment choice as well. In fact, we are so confident in EnStron’s performance, we backed our EnStron Underlayment PLUS with one of the best warranties in the industry. With our 15-year performance guarantee, you will not find a better underlayment panel.





arrow Consistency – EnStron is engineered to meet precision manufacturing standards. It has no core voids or hidden imperfections.
arrow Smooth Surface – EnStron’s exceptionally smooth surface means it provides superior bonding between the floor covering adhesive and the panel. The consistent face means you don’t have to worry about panel imperfections, delaminating, or seaming after you lay vinyl floor coverings. Sanding tolerance is a low .005.
arrow Density – At 46.5 lbs/cu. ft. EnStron is twice as dense as Lauan plywood. It deflects and resists panel damage from impacts like dropped tools better than other underlayment products. Panels with high density enable nails and screws to hold tighter, reducing floor squeaking and panel movement.
arrow Surface Hardness – EnStron’s superior hardness helps eliminate the need for panel patching and sanding. Unlike Lauan plywood, fasteners will not split the surface of Enstron.
arrow Solid One-Piece Construction – No need to worry about call-backs due to veneer delamination. EnStron is an integrated panel with no layers, therefore it holds together, even in high moisture areas like bathrooms and kitchens.
arrow Environmentally-Friendly – EnStron is made from 100% recycled waste from wood products. It is an environmentally superior option versus Lauan plywood. It is composite panel made with no added formaldehyde (NAF) resins. The result is a panel third party tested to 0.00ppm.
arrow Storage and Handling – Always store EnStron panels flat on a minimum of 5 bunks or skids in dimensions of 2”x4”x48”, spaced evenly at least every 16”, with spacers between panels in a dry, covered, and level area.
