DGSL Polycarbonate Greenhouse Panels, 14-Pack 4'x2' Twin-Wall Sheets — 80% Light, Impact-Resistant

These are 14 DGSL twin-wall polycarbonate greenhouse panels (4' x 2' x 0.16") designed to let up to 80% light through, resist impact, and maintain a stable greenhouse environment across -44°C to 120°C.

Replace or upgrade your greenhouse roof and walls with durable, lightweight twin-wall sheets engineered for gardening demands. DGSL panels combine high light transmission with strong impact resistance and broad temperature tolerance, making them a practical option for hobbyists and small-scale growers who need a reliable covering that’s easier to work with than traditional metal or glass.

How do these panels affect light and temperature inside my greenhouse?

DGSL twin-wall polycarbonate sheets transmit about 80% of available light, balancing brightness with diffusion to reduce hot spots. Their twin-wall construction traps air between the layers to provide insulating value, helping moderate interior temperature swings.

• 80% light transmission for healthy, even illumination
• Light diffusion reduces direct sun scorching on delicate plants
• Air gap between walls improves thermal insulation
• Working temperature range: -44°C to 120°C

Are these polycarbonate panels durable and safe against impacts?

Yes — the panels are made from impact-resistant polycarbonate that is far less likely to shatter than glass. That resilience makes them suitable for areas with hail, falling branches, or accidental knocks during greenhouse maintenance.

• High impact strength and shatter resistance
• Lightweight yet structurally strong for typical greenhouse frames
• Better safety than single-pane glass in breakage scenarios
• Long-lasting performance under normal weather exposure

How easy is it to cut, fit, and install these sheets?

Installation is straightforward: the twin-wall panels can be cut with a utility knife or scissors to fit your frame. Adhesive backing is removable for simple placement; align and press into position, then secure with compatible fasteners or sealants recommended for polycarbonate.

• Cuttable with common tools (cutter knife or scissors)
• Peel-off adhesive backing for quick placement
• Fits standard greenhouse framing systems when trimmed to size
• Minimal specialized hardware required for most installations

What sizes and quantity are included, and how do I plan for replacement?

This pack contains 14 sheets, each sized 4 feet by 2 feet with a 0.16" twin-wall thickness. Measure your greenhouse panels and plan overlaps or trims; having a spare sheet or two simplifies phased replacement and future repairs.

• 14 sheets per pack (4' x 2' x 0.16" each)
• Twin-wall design for strength and insulation
• Order extra for overlap, cutting errors, or phased installs
• Compatible with most hobby and small greenhouse frames

Who this is for: gardeners, greenhouse hobbyists, and small-scale growers seeking a lightweight, safer alternative to glass — ideal for those who want good light transmission, improved insulation, and resilience to impacts. These DGSL sheets suit DIY installers who need panels that are simple to cut and fit, and who want reliable material performance across wide temperature ranges.
