NWFA Mandatory Installation Rules for Solid 3/4" Hardwood
Never install flooring tight against drywall or door jambs. Seasonal changes in relative humidity cause wood and rigid cores to expand. A 0.5" perimeter gap avoids buckling and peaked joints.
Butt ends between adjacent rows must be separated by at least 6 to 8 inches. Repeating H-joints or steps creates structural failure and click-lock separation under heavy furniture.
Based on NWFA contractor production benchmarks including underlayment, field click-lock, and baseboard installation.
Includes 10 boxes, baseboards, quarter rounds, and transition strips (US National Retail Average).
Extra square footage stored flat in a climate-controlled room for future dye-lot matching board repairs.

Frequently Asked Questions: 180 Sq Ft Flooring Takeoff
How many boxes of Solid 3/4" Hardwood do I need for 180 sq ft?
For a 180 square foot project, you should purchase exactly 10 boxes. With an industry-standard 8% waste factor, this yields 200 sq ft of total material, giving you 20 sq ft per box and leaving ample attic stock for future replacements.
Why is an extra 8% waste factor recommended for this installation?
Every room requires cutting boards to fit perimeter walls, door jams, and closet alcoves. Off-cut ends shorter than 6 to 8 inches cannot be reused under NWFA joint-stagger rules. Factoring in 8% prevents project delays caused by dye-lot mismatch if you run out of boxes midway through installation.
Do I need separate underlayment padding for 180 sq ft of flooring?
Yes, this material requires approximately 2 roll(s) of 100 sq ft acoustic moisture underlayment pad. Remember to seal all seams with heavy-duty polyethylene vapor tape.
How wide of an expansion gap should be left around the room perimeter?
Per NWFA and NALFA standards, maintain an uninterrupted 1/4" to 3/8" (up to 1/2" for solid hardwood) expansion gap against all vertical walls and door frames. This gap is neatly concealed by baseboard and quarter round molding to allow natural seasonal expansion without floor buckling.
