Key Stone Blocks – Stylish, Functional, and Rain-Screen Ready

Key Stone Blocks offer a perfect fusion of elegant design and functional performance, making them a top choice for rain screen applications. These blocks are engineered with a decorative drip channel that actively funnels water away from the building, protecting the exterior from moisture buildup.

Integrated weeping holes prevent condensation and promote continuous airflow, ensuring your walls stay dry and ventilated. This combination of features keeps your structure safe, while enhancing energy efficiency and long-term durability.

The large rear angle makes cleaning simple and supports fast peel-and-stick installation. Whether you’re working on new construction or a retrofit, installation is quick and precise.

Each block includes a removable 3-inch trim ring, offering flexibility across various siding types and project requirements.


Designed for Timeless Style and Practical Use

Crafted with a deep wood grain texture and sharp miter joints, Key Stone Blocks replicate the look of real wood while providing superior weather resistance. They blend easily with traditional and modern exteriors, offering both curb appeal and professional finish.

Unlike glued screens that detach over time, these blocks feature a molded-in screen that prevents insect intrusion while staying permanently secured. This ensures minimal maintenance and consistent protection, year after year.
