Construction Panels

Huber AdvanTech

Everything rests on your subfloors. From granite countertops and floor coverings, to your footsteps and furniture – the subfloor you choose today is the base your home depends on for a lifetime. Because it’s engineered with a unique resin technology for advanced moisture resistance and more wood for superior strength and stiffness, AdvanTech® subfloors give your finished floors a smooth, flat surface with a luxurious, solid feel.
Unlike other subfloor alternatives, AdvanTech subfloors stand up against moisture to help protect your home from potential weather-related delays and rework during construction, while helping to ensure quiet, stiff floors with no creaking or nail pops over time. When you choose AdvanTech subfloors, you choose new floors for a lifetime – a promise backed by a Lifetime Limited Warranty.

Huber Zip System

Seasons change, but your indoor comfort shouldn’t. Air leakage can increase energy costs because it makes heating and cooling systems work harder to keep your home cool in the summer and warm in the winter. With ZIP System® sheathing and tape, you can build in protection against air leakage and possible moisture damage within your walls. ZIP System® sheathing and tape is a revolutionary solution for exterior walls and roofs with a built-in moisture barrier and air-tight, taped seams, to keep air and moisture out and energy savings and comfort in.
