Description
xOverview
Upgrade or replace greenhouse roofing with Sinimaka 10 pack twin wall polycarbonate panels. Each panel measures 6 feet by 2 feet and sits about 0.16 inches thick. The twin wall design combines lightweight handling with rugged impact resistance, making these sheets well suited for greenhouses and similar projects where clear visibility and durability matter.
Why these panels stand out
Engineered to perform across a wide range of conditions, the panels stand up to extreme weather from minus 40 Celsius to 120 Celsius. They offer solid heat preservation and insulation, which can help create a more stable growing environment across seasons. While not a guarantee, the insulation characteristics may help reduce heat loss at night and during cold snaps.
- Impact-resistant twin wall structure designed to endure hail and impact without cracking
- All-weather resilience that accepts temperature swings and heavy precipitation
- Good insulation properties to help stabilize your greenhouse interior
Light, clarity, and growth
The panels feature a high-transparency surface with a UV-resistant coating. They block up to 99.9% of UV rays while delivering approximately 89% light transmission. The double-layer construction diffuses light, creating a gentler, more uniform light environment that can support steady plant growth.
- High clarity for strong ambient daylight inside structures
- Diffused light helps minimize hot spots and shadows
- UV protection paired with robust light transmission
Workable and DIY-friendly
These sheets are lightweight, making handling and installation easier and potentially less costly. They cut without cracking or splintering, and they can be cold-bent to form curved roof profiles. This makes them a practical option for DIY garden builders and modest renovation projects.
Versatile applications
Beyond greenhouses, the panels suit a variety of uses where clear, durable cover is desired. Possible applications include pool or aisle roofs, garden fences, cold frames, aquarium lids, chicken coop roofs, hurricane windows, and more. The combination of aesthetics and practicality supports flexible designs.
What you get
