Product Advantage
With a double-layer PP woven structure and 15% built-in insulation cotton, it increases the greenhouse’s night temperature by 3-5℃ and reduces heat loss by 40%. Compared with ordinary single-layer curtains, winter heating energy consumption decreases by 35%, stabilizing the crop growth environment. It’s a core advantage of woven fabric greenhouse insulation curtains, suitable for high-temperature-demand crop cultivation.
Light transmittance reaches over 85% (GB/T 2680-2021) with a light uniformity ≥90%, avoiding the "severe light blocking" issue of ordinary curtains. It ensures crops get sufficient light throughout the day, promoting photosynthesis and shortening the growth cycle of leafy vegetables by 5-7 days, meeting the needs of high-transmittance greenhouse curtains.
Added with 0.8% UV stabilizer and anti-aging coating, it retains ≥85% tensile strength after 3-year simulated outdoor exposure (xenon lamp test). It resists acid and alkali (PH 3-11) without cracking or embrittlement in harsh weather, with a service life of over 5 years—67% more durable than ordinary curtains (2-3 years), making it a top choice for anti-aging greenhouse curtains.
With IPX5 waterproof coating (no leakage under continuous low-pressure spraying), it achieves 100% moisture resistance in humid environments. Its mold resistance reaches Grade 0 (GB/T 24346-2021, no mold growth), avoiding mold pollution to crops. It’s suitable for moisture-proof greenhouse curtains in rainy southern areas.
Weighing only 200-250g/㎡ (1/3 the weight of traditional canvas curtains), it lifts at 0.5m/s with an electric rolling system—50% more efficient than canvas. Soft and easy to fold, it takes little storage space, and one person can complete daily maintenance, reducing labor costs for greenhouse curtain operation.
With longitudinal tensile strength ≥25kN/m and tear strength ≥1.8kN, it resists level 8 winds (17.2-20.7m/s) without deformation or tearing. Double-line edge locking prevents thread breakage, stably protecting the greenhouse structure, suitable for wind-resistant greenhouse insulation curtains in windy northern areas.

Product Uses
In areas with -10℃ to 0℃ winter nights, its 3-5℃ temperature increase and 40% heat loss reduction keep tomatoes, cucumbers warm. Withstands level 8 winds, preventing curtain damage. Reduces heating energy costs by 35%, ideal for large-scale winter veggie cultivation.
Its IPX5 waterproof grade and 0-level mold resistance fight frequent rain and high humidity. Blocks excess moisture, avoiding mold on mango, banana plants. 85% light transmittance ensures sufficient light, maintaining fruit sweetness—perfect for humid, rainy southern greenhouse operations.
Seedlings need stable temps and uniform light. Its ≥90% light uniformity promotes even seedling growth, while heat retention stabilizes 20-25℃ day/night temps. Lightweight design (200-250g/㎡) works with electric rollers for quick temp adjustments, cutting seedling cycle by 5-7 days.
Flowers (roses, lilies) need consistent environments. Its 5-year service life (67% longer than ordinary curtains) reduces replacement costs. Anti-UV coating prevents color fading on flowers. Easy operation suits large greenhouses, ensuring stable blooms for commercial supply.
FAQ
Q1: Can this woven fabric protector be cut to fit irregularly shaped battery boxes in mobile energy storage vehicles?
A: Yes. It's highly flexible and supports on-demand cutting. The 30-50m roll design ensures minimal waste, and it fits tightly to irregular shapes without affecting its waterproof or flame-retardant properties.
Q2: How often does the protector need replacement when used in sun-exposed PV energy storage stations?
A: With UV stabilizers, it has an outdoor service life of over 5 years. Annual inspections for wear are recommended, but replacement is only needed if tears or strength loss (below 80% of original) occur.
Q3: Will the IP65 waterproof performance decrease after long-term exposure to heavy rain in coastal areas?
A: No. It undergoes strict marine-grade waterproof testing; heavy rain or salt spray won't reduce its waterproofing. After 3 years of coastal use, IP65 grade remains intact.
Q4: Can it be used with anti-corrosion coatings on battery box surfaces without affecting adhesion?
A: Yes. Its surface texture won't interfere with coating adhesion. It can be installed directly over cured anti-corrosion coatings, enhancing protection without compromising the coating's effectiveness.
