When choosing and installing polycarbonate solid sheets, it's important to consider factors like thickness, UV protection, and transparency based on your project’s needs. For roofing or outdoor applications, opt for sheets with UV coatings to ensure durability. Always leave expansion gaps during installation to accommodate temperature changes, and use proper fasteners to prevent cracking. PC sheets can be easily cut, shaped, and drilled with the right tools, making them ideal for custom projects. Proper installation ensures optimal performance and longevity of your PC sheets.
