Custom Aluminum Folding Window

Overview

Aluminum folding windows are available in several innovative configurations to accommodate diverse architectural needs. The principal types include horizontal folding, vertical folding, bi-fold, and multi-panel linked folding designs.

Key Features:

Flexible and Wide Opening: Multiple sashes fold neatly to one or both sides, maximizing the clear opening for ventilation, natural light, and unobstructed views.
Compact Storage: When opened, the panels stack compactly, saving interior and exterior space and enhancing usability.
Versatile Application: Suitable for both residential and commercial spaces, especially where a seamless indoor-outdoor transition is desired.

Due to their ability to create wide, barrier-free openings, aluminum folding windows are an ideal solution for large window apertures and commercial service counters, such as shop selling windows.

Horizontal Folding Windows

Horizontal folding windows feature multiple panels that fold and slide horizontally along tracks, creating wide openings when fully opened.

Structure: Aluminum frame with horizontal track system, hinged sashes, pivot hinges, rollers, multi-point locks, handles, glass panels, and sealing strips.

Features: Ideal for wide openings and panoramic views. Panels fold to one or both sides, offering flexible opening configurations. Perfect for patios, terraces, and commercial storefronts requiring seamless indoor-outdoor transitions.

Vertical Folding Windows

Vertical folding windows operate with panels folding upward or downward along vertical tracks, suitable for specialized applications and counter-style openings.

Structure: Aluminum frame with vertical track system, vertically-hinged sashes, pivot hardware, counterbalance mechanisms, locking systems, handles, glass panels, and weather sealing.

Features: Excellent for service windows, kiosks, and food service applications. Vertical folding saves horizontal space and provides easy transaction access. Ideal for commercial environments requiring frequent operation.

Bi-Fold Windows

Bi-fold windows consist of two hinged sashes that fold together like a book, offering a simple solution for medium-sized openings.

Structure: Aluminum frame with dual-track system, two hinged sashes, central pivot hinge, rollers, coordinated locks, handles, glass panels, and perimeter sealing.

Features: Cost-effective and space-efficient design balancing opening area with structural simplicity. Reliable operation with minimal maintenance. Suitable for residential and light commercial applications with moderate opening requirements.

Structure of Folding Windows

Aluminum folding windows consist of several essential structural components, carefully designed for durability, performance, and flexibility. Below is a detailed breakdown of its structure:

1. Fixed Frame and Movable Sashes

Aluminum folding windows are engineered with an emphasis on functionality, strength, and smooth operation. The primary structural components include:

1.1 Frame and Sash:

Frame and Track Integration: The frame and guide track are manufactured as a single, unified system. This ensures stability and precise alignment for the folding panels.
Sash Lightweight Design: The window sash utilizes lightweight aluminum profiles, reducing the overall weight. This design minimizes the mechanical load exerted on hinges, rollers, and other hardware, prolonging system lifespan and ensuring easier operation.

1.2 Aluminum Material:

Typically made of 6063-T5 or 6061-T5 aluminum profiles, providing excellent strength, corrosion resistance, and machinability.

1.3 Thermal Break Technology:

Polyamide thermal break strips are integrated into frame profiles to minimize thermal conductivity and enhance energy efficiency while maintaining structural integrity.

1.4 Surface Treatment:

The aluminum profiles for folding windows are available with several customizable surface treatments to enhance durability and visual appeal:

Anodizing: Offers superior corrosion resistance and a sleek metallic appearance. Standard color options include silver, champagne, bronze, black, and gold.
Electrophoresis: Provides a uniform, smooth, and durable finish with excellent abrasion resistance. Common colors include silver, champagne, coffee, and black.
Powder Coating: Delivers a hard-wearing, weather-resistant surface with a broad selection of colors. Available in all standard RAL and custom colors, including matte, gloss, and textured finishes.
Wood Grain Finish: Recreates the look of natural wood using heat transfer technology. Popular choices include oak, walnut, cherry, teak, and other custom wood patterns.
PVDF Coating: Uses polyvinylidene fluoride for maximum durability and resistance to UV, chemicals, and extreme weather. Available in a wide range of colors, including metallic and deep matte tones.

2. Hardware Components

Hinges & Rollers: Heavy-duty pivot hinges and rollers facilitate the synchronized folding and sliding of multiple window panels along the integrated track.
Locking Mechanisms: Multi-point locks and secure handles ensure safety, ease of use, and reliable closure.
Auxiliary Hardware: Additional fittings, such as adjustment screws and limiters, maintain alignment and prevent panel misoperation.

3. Sealing Components

Weather Stripping: High-performance sealing strips and compression gaskets are applied at all interfaces—between the frame, sash, and adjacent panels—to prevent air and water leakage.
Interpanel Seals: Specially designed seals at panel junctions maintain insulation and weather tightness even during repeated operation.

4. Glass Options

The glass installed in aluminum sliding windows determines their thermal and sound insulation properties. Common glass options, along with typical thickness ranges, include:

Single Tempered Glass: A basic, durable, and cost-effective choice. Common thicknesses: 5mm, 6mm, or 8mm.
Laminated Double Glass: Enhanced security and soundproofing, made by bonding two layers of glass with an interlayer. Common thickness: 5mm+0.38mm+5mm or 6mm+0.38mm+6mm.
Insulated Glass (IGU): Two panes of glass separated by a spacer for improved thermal insulation. Common thickness: 5mm+12A+5mm, 6mm+12A+6mm, or variations with larger spacers for better insulation.
Triple Glass (Laminated + Insulated): Offers superior thermal and sound insulation by combining laminated glass with insulated glass. Common configuration: 5mm+9A+5mm+9A+5mm.
Low-E Coated Glass: Glass with a Low-E coating to optimize energy efficiency by reducing heat transfer while maintaining natural light. Can be combined with insulated configurations like 5mm+16A+5mm (Low-E).
