Product Description

Double Glass Patio Folding Doors is an aluminum folding door system designed for outdoor courtyards. It uses high-strength aluminum alloy frames and double or multi-layer glass panels, and realizes multi-leaf linkage folding through hinges and tracks. Its core function is to completely retract the door body to one side through space folding technology, maximizing the connectivity between the courtyard and the indoor space, while taking into account wind protection, heat insulation, sound insulation and safety performance.

Customized Waterproof Aluminum Folding Doors Core advantages and features

Spatial flexibility and visual transparency

Fully folding design: The door leaf can be completely retracted to one side, and the space occupied after opening is reduced by more than 80%, which is suitable for narrow courtyards or small apartments.

Obstacle-free vision: The width of a single glass leaf can reach 1000mm, and the height can be customized to 3000mm. With Low-E glass transmittance ≥85%, it can achieve seamless connection between indoor and outdoor landscapes.

Excellent physical properties

Wind pressure resistance and wind protection: The wall thickness of the aluminum alloy profile is ≥2.0mm, and the wind pressure resistance level reaches level 9 (wind speed ≥24.4m/s), which is applicable to coastal areas.

Heat insulation and energy saving: The broken bridge aluminum structure is matched with hollow glass (5mm+12A+5mm), and the heat transfer coefficient K value is ≤2.0W/(m²·K), which is 30% more energy-saving than ordinary doors and windows.

Sound insulation and noise reduction: The sound insulation performance reaches RW=35dB, which effectively blocks traffic noise (such as the noise of urban main roads can be reduced by 20dB).

Durability and low maintenance

Material life: The aluminum alloy surface is fluorocarbon sprayed, and the corrosion resistance reaches AAMA 2605 standard, the salt spray test is ≥2000 hours, and the outdoor service life exceeds 20 years.

Hardware system: The hinge is made of 304 stainless steel, with a load-bearing capacity of ≥150kg/set and a folding life of ≥100,000 times; the pulley group is equipped with high-speed rail-grade bearings, and the push-pull resistance is ≤20N.

Safety and anti-theft

Glass configuration: Standard 5mm tempered glass (impact strength ≥120J), optional laminated glass (impact strength ≥300J) to prevent breakage and splashing.

Lock system: Multi-locking point anti-theft lock cylinder, in line with PAS 24 security standards, 50% improvement in anti-pry performance.

Aluminum Folding Doors Aesthetics and personalization

Surface treatment: More than 10 colors are available, including matte black, champagne gold, wood grain transfer, etc., and RAL color card customization is supported.

Design style: It can be adapted to a variety of decoration styles such as modern minimalism, industrial style, French retro, etc., and the frame-sash ratio is adjustable (1:2 to 1:4).

Planning and installation suggestions

Size and layout planning

Opening size: Single sash width is recommended to be ≤1000mm, total width is recommended to be ≥3000mm (3 sashes are required for ordering), and height is recommended to be ≤3000mm (avoid ultra-high customization costs).

Folding direction: Choose left or right opening according to the courtyard layout. The two-way folding design requires storage space on both sides (≥500mm on each side).

Threshold design:

Barrier-free threshold: height ≤15mm, suitable for indoor and outdoor flat connection to prevent tripping risks.

Windproof drainage threshold: height 30-50mm, with drainage groove design, windproof level increased by 2 levels.

Functional requirements matching

High-frequency use scenarios (such as connecting the restaurant and the courtyard): choose heavy-duty pulleys and silent hinges to reduce noise and maintenance frequency.

Privacy demand scenarios (such as bedroom balconies): with electric blinds or frosted glass, the light transmittance can be adjusted to 30%-50%.

Safety demand scenarios (such as low-rise residential buildings): add anti-pinch rubber strips and child locks, the number of lock points ≥ 6.

Installation and maintenance points

Basic requirements:

Wall load-bearing: Concrete beams must be embedded above the opening, with a load-bearing capacity of ≥ 200kg/m.

Horizontal error: The horizontality of the track installation surface is ≤2mm/m, and the verticality is ≤1.5mm/m.

Construction process:

Measure the size of the opening and confirm the door body division plan.

Install the lower rail and the upper rail, and fix the expansion bolt spacing ≤500mm.

Hoist the door leaf and adjust the gap between the hinge and the pulley.

Install the sealing strip and lock, and test the smoothness of pushing and pulling.

Maintenance cycle:

Daily cleaning: Wipe the track and glass with a soft cloth every month to avoid sand accumulation.

Hardware maintenance: Add lithium-based grease every six months and check the looseness of the hinges.

Sealing strip replacement: Replace the aged sealing strip every three years to prevent air leakage and water leakage.

Cost and budget

Material cost: Aluminum alloy frame accounts for about 40%, glass accounts for 30%, hardware and installation each account for 15%.

Customization options: Electric opening system (increase cost by 30%), intelligent sensing system (increase cost by 50%).

Long-term benefits: Energy saving effect (saving electricity bills per year compared with ordinary doors and windows), property value-added (improve space utilization).
