AdvanTech X-Factor, Huber Engineered Woods’ new premium subflooring, features a fade-resistant, water-shedding surface. According to Huber, the built-in protective top guards against flaking, delamination, or discoloration. This surface is also marker-friendly, which reportedly is great for jobsite communication. The long edges of the panel have tongue-and-groove joints, and the panel’s bottom surface is fully sanded. Huber says that panels are made with SFI-certified woods and do not off-gas urea formaldehyde or VOC emissions. Pricing unavailable.
