Format
Wide-Plank Flooring Flooring
Wide, long boards (typically 7"–10"+) that make rooms feel larger and more custom — the defining look of modern mountain and luxury interiors.
Character
Why Wide-Plank Flooring
Look
Fewer seams and long, uninterrupted runs create an open, high-end, contemporary feel — especially in white oak.
Stability
Wide planks move more with humidity, so quality engineered construction and proper acclimation are key — exactly what mountain climates call for.
Species
Most often European or French white oak; also available in American oak and walnut.

What It Needs
Installing Wide-Plank Flooring
The requirements that apply specifically to this product — with the standard each one comes from.
NWFA tells you to glue-assist anything over 5 inches
This is a requirement, not a preference, and the reasoning is mechanical: a wider board means fewer fasteners per square foot of floor, so the fastening alone no longer restrains it. The guidelines state that wide plank — solid or engineered, over 5 inches — should be installed using the glue-assisted method when site conditions allow, unless the flooring manufacturer says otherwise. The adhesive has to be a wood flooring adhesive with elastomeric qualities, so it holds the board down while still permitting the normal seasonal movement the board will have.
NWFA Installation Guidelines
Movement scales in a straight line with width
Using the Forest Products Laboratory's coefficient for American white oak, a two-point drop in moisture content narrows a plainsawn board about 0.017 inch at 2¼ inches, 0.038 inch at 5 inches, 0.056 inch at 7½ inches and 0.075 inch at 10 inches. Nothing about wide plank is unpredictable — it is the same wood behaving the same way over a longer span. That is why the answer is engineered construction and a rift or quartersawn face rather than avoiding the width.
USDA FPL Wood Handbook, Table 13-5
Where the subfloor tolerance tightens
Because glue-assist is involved, the flatness requirement moves to the stricter of NWFA's two tiers: 1/8 inch in 6 feet or 3/16 inch in 10 feet, rather than the 3/16 inch in 6 feet allowed for mechanical fasteners of 1½ inches and longer. A subfloor that would have been acceptable under a nail-down strip floor is not automatically acceptable under wide plank.

Best For
Open-concept great rooms, mountain-modern homes, and anyone wanting a larger-scale, custom look.
How We Install It
We favor engineered wide-plank for dimensional stability at altitude, installed glue-down or floating over prepped, moisture-tested subfloors.

Frequently Asked Questions
Is wide-plank flooring good for mountain homes?
Yes — in quality engineered construction with proper acclimation and moisture prep, wide-plank white oak performs well through altitude humidity swings and delivers the open, custom look most mountain-modern homes want.
How wide can the planks go?
Common luxury widths run 7"–10" and up, in long lengths. Wider boards move more with humidity, so engineered construction and correct install become more important — we'll match the format to your home and climate.
