High Impact Waterproof WPC Cladding Withstands Severe Storm Environments
Product Details
Waterproof WPC Cladding
,High Impact WPC Cladding
Engineered with high-density solid co-extrusion, this WPC cladding delivers exceptional impact resistance against hail and debris. Its reinforced structural design certified for high wind loads prevents cracking and warping, making it a reliable, long-term exterior facade solution for coastal and storm-prone commercial regions.
Unlike hollow profiles, the solid composite core resists heavy blunt impacts from hail, ladders, or flying debris without denting or cracking.
The deep-groove interlocking system locks boards tightly together, withstanding wind pressures up to Category 13 typhoons when properly fixed.
Formulated with premium polymers that maintain material elasticity in freezing temperatures, preventing winter frost-shattering. 配方升级了优质聚合物,在极寒温度下仍能保持材料弹性,杜绝冬季因冻融循环导致的脆化断裂.

If the cladding panels are installed horizontally, the joists must be installed vertically (and vice versa). Fix the joists to the wall using expansion screws. Keep the center-to-center distance between the joists at 30cm - 35cm (if the spacing is too wide, the wall will sag or flex).
Start from the bottom or the side. Use a starter clip (or screws) to secure the edge of the first panel to the joists. Make sure to double-check that this first piece is perfectly level or vertical.
Insert the tongue (male profile) of the next panel into the groove (female profile) of the previous one. Snap the dedicated fixing clip onto the exposed joint where the panel meets the joist, and tighten the screw. Repeat this process, stacking them like building blocks.
Cut the final panel to fit the remaining space. Cover and seal all perimeter edges and corners using matching L-shape corner trims (secured with structural adhesive or a brad nailer).
A1: Yes. The outer co-extruded shield is a 360-degree polymer layer that completely blocks salt moisture penetration. Combined with our stainless steel heavy-duty clips, the entire system resists salt corrosion and high wind uplift in coastal areas.
A2: Our solid cladding passes the standard ball-drop impact test without structural failure. Under normal storm conditions, standard-sized hail (up to 25mm diameter) will not leave visible dents or puncture marks on the hardened co-extruded surface.
