Lauan (also known as Philippine Mahogany or Meranti)
Shorea spp. • Engineered (Plywood veneer)
Grain Pattern
Straight to interlocked grain with a relatively coarse, open texture; shows a faint cathedral pattern typical of rotary-peeled veneer.
Color Description
Medium reddish-brown to grayish-tan; sapwood is typically a pale yellow-gray. The luster is low to medium, and it tends to darken slightly with age and UV exposure.
Hardness Rating
800 lbf (Soft to Medium, depending on specific species density)
Durability Rating
Nondurable to Slightly Durable; susceptible to insect attack and rot if exposed to moisture.
Common Uses
Plywood facing, interior paneling, hollow-core doors, drawer bottoms, and inexpensive furniture backing.
Geographic Origin
Southeast Asia, particularly the Philippines, Malaysia, and Indonesia.
Market Value & Sustainability
Estimated Market Value
$3.00 - $5.00 per 4x8 sheet (estimated cost contribution of the veneer layer)
Wood Age Estimate
The oxidation and wear patterns suggest a sample that is 20-40 years old, likely part of mid-to-late 20th-century construction.
Sustainability Status
Many Shorea species are listed as Critically Endangered on the IUCN Red List due to over-logging; FSC certification is available but not standard for all Lauan products.
Workability
Easy to work with hand and machine tools, but the interlocked grain can cause fuzzy surfaces during sanding. Glues and finishes well but is prone to splintering.
Notable Features
Often lacks a distinct scent; contains some silica which can slightly dull cutters; widely used as a generic utility lumber substitute.
Finish Recommendations
Requires a grain filler for a smooth finish; takes stains well. Polyurethane or lacquer are recommended for protective interior use.
Identification Confidence
Medium-High; the coarse, open grain and reddish-brown hue are very characteristic of rotary-cut Lauan plywood commonly used in domestic construction.
