Polycarbonate Greenhouse Replacement Panels 4FT (Length) × 2FT (Width) × 6mm, Twin-Wall, 10 PCS

Give your greenhouse a fresh start with clear polycarbonate panels in the standard that fits most backyard frames. Each panel combines a hollow twin-wall core with a 4 mm build, trapping air between two layers so the interior holds warmth on cold nights and sheds excess heat in summer. The result is a steadier climate for seedlings, herbs and fruiting crops.
These greenhouse replacement panels are engineered around the qualities plants need most. The twin-wall structure slows heat loss in winter and softens summer heat, while the surface coating blocks 99% of harmful sun rays without dimming the light your crops rely on. Over 80% of natural sunlight passes through, feeding photosynthesis and keeping growth vigorous.
Features:
Thermal Insulation: The hollow twin-wall core holds warmth at night and releases excess heat by day, steadying the greenhouse climate across seasons.
High Light Transmission: Over 80% of sunlight passes through to feed plant growth while the coating blocks 99% of harmful sun rays.
Shatterproof Build: High-impact polycarbonate stands up to hail, storms and strong winds without cracking.
Wide Climate Range: Panels remain stable from -40°C to 120°C (-40°F to 248°F) without warping or turning brittle.
Easy Customization: Each sheet weighs about 0.75 kg (1.65 lb); trim it with a utility knife or fine-tooth saw and install it alone.
