When selecting materials for exterior walls, one of the most common questions from architects, contractors, and buyers is: “Is WPC cladding truly waterproof?”

Last summer, Felix laid out a slab of treated wood for his backyard patio. The materials cost less than six thousand yuan, and he felt he'd made a smart move—the same area would have cost his neighbor twelve thousand yuan for WPC flooring, double the price.

When it comes to outdoor patio renovations, many people immediately think of wood—its warm, natural texture is undeniably appealing. However, this comes with endless maintenance: painting, anti-corrosion, insect control, moisture protection… Anyone who has lived in a log cabin or laid wooden platforms knows how fragile natural wood is outdoors.
