Folding Windows
Folding windows open horizontally from the bottom, delivering fresh air with space-saving innovation.
Your Affordable Folding Window Manufacturer
The folding window has hinges on the top of the frame and can be easily opened by simply turning the crank at the bottom. Thanks to the top hinge design, these windows are the perfect solution to let in the breeze while keeping out the rain, perfect for places like bathrooms or kitchens. The versatile design of folding windows is perfect for pairing with picture windows to create a beautiful focal point.

Zhonglian: Precision-engineered folding windows for global projects.
Zhonglian’s folding windows deliver exceptional weather resistance and energy efficiency through aerospace-grade aluminum. We customize systems for global projects, from new builds to renovations, with patented sealing technology.
About aluminum profile color
Select from 200+ RAL Classic colors or request custom Pantone matches. Our anodized/aluminum frames undergo 3-stage anti-fade treatment for lasting vibrancy.
Glass Options
Configure with energy-certified glazing:
5+3+5mm double/triple tempered IG units (U≤1.1W/m²K)
Low-E coated glass (SC≤0.28)
Laminated safety glass (EN 12600 Class 1)
Integrated with ISO-certified gear sets (VBH/ROTO/HOPO). Multi-point locking exceeds 1500N anti-burst force (PAS 24:2012), with 50,000-cycle durability testing.
Engineered for Extreme Conditions
Miami-Dade certified folding systems withstand Category 5 hurricanes (ASTM E1996) with 12,000Pa wind load resistance.
Seamless Living Space Transformation
Configurable for sunrooms to terraces with RAL-matched finishes complementing contemporary to coastal aesthetics.
Aluminum folding windows utilize EN AW-6060 T6 alloy frames certified to EN 12210 Class P9 weather resistance. This aerospace-grade material withstands -30°C to 80°C extremes without warping/cracking, with 3000-hour salt spray certification (ISO 9227). Configurations span ≤6m per unit, structurally validated per EN 1999-1-1 standards for custom project integration.
EN 13947-Certified Eco Performance
Zhonglian’s thermally broken frames achieve Uf≤1.2W/m²K (EN ISO 10077-2), paired with triple glazing (Ug=0.5W/m²K) for 45% HVAC reduction per EN 13947. The recycled aluminum content exceeds 80% (SGS-certified), with 95% lower embodied carbon versus virgin material (ISO 14044 LCA). Contributes to LEED v4.1 MRc4 credits.
Factors to Consider When Buying Folding Windows
Performance Specification
Define required metrics: 1.ACH≥4 for ventilation (EN 13141-1) 2.VT≥0.7 for view clarity (ISO 9050) 3.Security Class RC2 (EN 1627)
Aesthetic-Technical Integration
Match RAL colors to facade materials (ΔE≤1.5). Select frame profiles (60-120mm) per structural load calculations (EN 1999-1-1).
Life Cycle Cost Analysis
Evaluate: 1.Initial cost vs 25-year ROI (ISO 15686-5) 2.Energy savings ≥35% (EN 13947) 3.Maintenance index ≤0.3
The benefits of choosing Folding windows
Rain-Safe Ventilation
Folding windows allow continuous airflow during light rain, with integrated drainage channels preventing water ingress while maintaining ventilation.
Forced Entry Resistance
Interlocking frames with stainless steel multi-point locks create a unified barrier, blocking intrusion attempts at every connection point.
Architectural Integration
Minimal-profile frames maximize glass area, achieving clean sight lines that complement both modern and traditional building designs.
