FEEL CONFIDENT IN THE QUALITY OF MASTIC

Mastic’s cutting-edge siding solutions combine advanced science, engineering and R&D to deliver uncompromising performance that stands up to Mother Nature’s worst.

Secure Locking Systems

Mastic’s T3-LOK® Panel Locking System grips panels together for fast, easy installation. It’s uniquely designed lock tightens under pressure to keep siding in place during extreme weather conditions.

Deep Projection For Strength and Beauty

Enhanced full 3/4 inch panel projection and uniquely angled, Mastic panels create straighter, deeper shadow lines for a premium look. And since the color is throughout the panel, nicks and scratches are virtually eliminated.

Robust Roll-Over Nail Hems

Our panels are engineered to be 200% more rigid than standard siding with robust roll-over nail hems. Mastic technology boosts durability, making our panels more resistant to cracking, impact and thermal distortion.
