Elevate your agricultural productivity with the Venlo Glass Multi-Span Greenhouse – a Dutch-engineered masterpiece that sets the gold standard for controlled environment farming. Renowned for its superior light transmission, structural efficiency, and timeless durability, this greenhouse is tailored for high-yield cultivation of premium crops, where precision and consistency are non-negotiable.​

Core Advantages​
1. Unrivaled Light Performance​
High-Transmittance Glass Panels:​
4mm/5mm clear tempered glass with 91% visible light transmission, optimizing photosynthesis for crops like tomatoes, cucumbers, and roses.​
Low-iron options available for enhanced light diffusion, reducing leaf burn and promoting uniform growth.​
Anti-reflective coating (optional) increases light capture by 5–8% in low-light seasons.
​
2. Robust & Long-Lasting Structure​
Hot-Dip Galvanized Steel Frame: Heavy-duty profiles with 300g/m² zinc coating ensure corrosion resistance, supporting a 25+ year lifespan.​
Venlo-Style Design: Narrow gable spans (3.2m–4.0m) and reinforced trusses maximize structural stability while minimizing shadow areas.​
Weather Resistance:​
Wind load capacity up to 160 km/h (certified for coastal and high-wind regions).​
Snow load tolerance of 80cm, with optional snow melting systems for alpine climates.
​
3. Advanced Climate Control​
Thermal Insulation:​
Double-glazed units (4mm+4mm) with argon gas filling reduce heat loss by 40% compared to single glass.​
Triple-glazed options for extreme cold zones, maintaining stable temperatures even at -25°C.​
Precision Ventilation:​
Continuous ridge vents (15–20% of roof area) paired with sidewall vents for natural airflow.​
Integrated fan-pad cooling systems for temperature regulation in hot climates, achieving 1–2°C precision.​
Smart Automation: Compatible with climate management software (e.g., Priva, Hoogendoorn) for automated control of vents, shading, and CO₂ enrichment.
​
4. Space-Efficient & Scalable​
Multi-Span Configuration: Interconnected bays with modular lengths (customizable from 10m to 100m+) and ridge heights (3.5m–6m) maximize land utilization.​
Column-Free Interiors: Wide aisles (1.8m–2.4m) and minimal support columns enable easy machinery access and optimize planting density.​
Zoning Capabilities: Internal partitions with thermal curtains allow separate climate zones for multi-crop cultivation or growth stages.
