Huber Engineered Woods Huber AdvanTech Subflooring
Huber AdvanTech moisture-resistant OSB subflooring panels — the premium subfloor alternative to commodity OSB and plywood.

Tongue-and-groove edges; 500-day moisture warranty when seams are taped with AdvanTech Seam Tape. No added urea formaldehyde. DOC PS2; APA Rated Sturd-I-Floor. Available in 19/32 in, 23/32 in, and 1-1/8 in thicknesses. Compatible with radiant in-floor heat systems.
