A 4mm polycarbonate sheet is a lightweight and easy-to-handle twinwall polycarbonate sheet. It can be used in a variety of DIY projects around the home and garden. Commonly, 4mm polycarbonate is a popular choice for replacement greenhouse panels, or cloches to protect seedlings from inclement weather. It has excellent light transmission, giving you a very clear and bright light, where it is used. Clear polycarbonate is a popular choice over glass due to its resilience and shatterproof nature, glass is notoriously fragile, and can be easily broken.
