Why Choose Hinged Windows
Hinged windows remain one of the most popular window styles in Singapore for good reason. Their design offers a unique combination of performance, aesthetics, and practicality suited to both tropical climates and modern architectural styles.
Types of Hinged Windows We Offer
Sinhao E&C provides a comprehensive range of hinged window configurations to suit different spaces, building types, and design preferences across Singapore.
Single Hinged (Casement) Window
The classic configuration with a single sash hinged on one side. Ideal for kitchens, bathrooms, and smaller openings. Opens fully for maximum ventilation and easy cleaning.
Double Hinged (French Casement) Window
Two sashes hinged on opposite sides that open outward from the centre. Creates a wide, elegant opening perfect for living rooms, bedrooms, and balconies.
Top-Hinged (Awning) Window
Hinged at the top and opening outward from the bottom. Allows ventilation even during rain — an excellent choice for Singapore’s frequent downpours. Often used in combination with fixed panels.
Bottom-Hinged (Hopper) Window
Hinged at the bottom and opening inward from the top. Commonly installed in basements, utility areas, and stairwells where outward-opening is not feasible.
Fixed + Hinged Combination Window
A fixed glass panel paired with one or more operable hinged sashes. Maximises natural light while providing targeted ventilation — a popular choice for HDB and condominium renovations.
Premium Materials for Singapore's Climate
We offer hinged windows in a range of frame materials and glass options, each selected for performance in Singapore’s hot, humid, and high-rainfall environment.
Frame Materials
Aluminium Alloy — The most popular choice for Singapore properties. Lightweight, corrosion-resistant, and available in powder-coated finishes across dozens of colours. Requires minimal maintenance and offers excellent structural strength.
Steel — Preferred for commercial and industrial applications where enhanced strength and security are required. Steel hinged windows offer a slimmer profile with greater load-bearing capacity.
Timber — A premium option for landed homes seeking a natural, warm aesthetic. Our timber frames are treated for moisture and termite resistance, ensuring longevity in Singapore’s tropical conditions.
Glass Options
Clear Float Glass — Standard option offering good transparency and light transmission.
Tinted Glass — Reduces solar heat gain and glare while maintaining outward visibility. Ideal for west-facing windows.
Tempered (Toughened) Glass — Up to five times stronger than standard glass. Breaks into small, blunt pieces for safety. Required by BCA for certain window locations.
Laminated Glass — Two layers of glass bonded with an interlayer. Provides enhanced security, sound insulation, and UV protection. Recommended for ground-floor units and noise-sensitive areas.
Double-Glazed (Insulated Glass Unit) — Two panes separated by a sealed air gap for superior thermal and acoustic insulation. Increasingly popular in Singapore for energy-efficient homes.
How We Install Your Hinged Windows
From initial consultation to final handover, Sinhao E&C follows a proven, transparent process that ensures every hinged window installation meets the highest standards of quality and safety.
BCA-Compliant Hinged Window Installations
At Sinhao E&C, we adhere strictly to the Building Control Act (BCA) standards in Singapore. All hinged window installations are carried out in full compliance with BCA regulations, including requirements for window safety devices, structural integrity, and approved materials.

Factors That Affect Hinged Window Pricing
- 📏 Window Size: Larger windows require more material and heavier-duty hardware. Standard HDB window sizes are more affordable than custom oversized panels.
- 🪟 Glass Type: Clear float glass is the most affordable. Tinted, tempered, laminated, and double-glazed options each add 20%–80% to the base glass cost depending on specification.
- 🔩 Frame Material: Aluminium is the most cost-effective. Steel adds 30%–50% for enhanced strength. Timber is the premium option, costing 50%–100% more than standard aluminium.
- 🎨 Finish & Colour: Standard white and silver are included in base pricing. Custom powder-coat colours, wood-grain finishes, and anodised treatments may incur additional charges.
- 🔧 Hardware & Locking: Basic push handles are standard. Upgrading to premium crank handles, multi-point locks, or child-safety restrictors adds $30–$120 per window.
- 🏗️ Installation Complexity: Ground-floor installations are straightforward. Upper floors, tight spaces, or structural modifications (e.g., widening openings) increase labour costs.
- 🗑️ Old Window Removal: Removing and disposing of existing windows adds $50–$150 per window depending on type and condition. Sinhao includes this in all standard quotes.
- 📐 Quantity & Scope: Full-home replacements (8–15 windows) typically qualify for volume discounts. Single-window replacements may have a minimum service charge.

What is a Hinged Window?
A hinged window, also known as a casement window, is a type of window where the sash is attached to the frame by one or more hinges on the side. It swings outward or inward using a handle, crank, or push mechanism, providing excellent ventilation, an airtight weather seal, and unobstructed views of the outside.
In Singapore, where the tropical climate brings intense sunlight, high humidity, and frequent heavy rainfall, hinged windows are an ideal choice for both residential and commercial properties. When closed, the sash presses firmly against a compression gasket, creating a seal that keeps out rain, dust, and humidity far more effectively than sliding windows.
Hinged windows are widely used across HDB flats, condominiums, and landed homes in Singapore, and are one of the most popular window types recommended by architects and interior designers for their combination of functionality, security, and clean aesthetic lines.

Materials Used in Hinged Windows
Selecting the right material for your hinged window frames is essential for durability, maintenance, and aesthetic integration with your property. Here’s an overview:
🪟 Aluminium Alloy
The most popular choice in Singapore. Lightweight, corrosion-resistant, and available in powder-coated finishes across dozens of colours. Requires minimal maintenance and offers excellent structural strength for hinged window frames.
🔩 Steel
Known for its strength, steel provides long-term protection and enhanced security. Often galvanized or powder-coated to prevent rust. Preferred for commercial and industrial applications requiring maximum load-bearing capacity.
🪵 Timber
A premium option for landed homes seeking a natural, warm aesthetic. Our timber frames are treated for moisture and termite resistance, ensuring longevity in Singapore’s tropical conditions. Offers excellent natural insulation properties.
🪟 Glass Options
Choose from clear float, tinted, tempered (toughened), laminated, or double-glazed insulated glass units. Each option offers different benefits for UV protection, security, sound insulation, and energy efficiency.
The Benefits of Hinged Windows for Singapore Homes
Choosing the right windows impacts your comfort, energy bills, and property value. Here’s how hinged windows benefit Singapore homeowners:
Superior Ventilation
Hinged windows open fully — the entire sash swings outward or inward — allowing maximum airflow into your space. This is particularly valuable in Singapore’s tropical climate, where cross-ventilation can significantly reduce reliance on air conditioning.
Tight Weather Seal
When closed, hinged windows press firmly against the frame gasket, creating an airtight compression seal that keeps out rain, dust, and humidity — far more effective than the overlap seal of sliding windows.
Energy Efficiency
The superior sealing of hinged windows reduces air leakage, helping maintain cooler indoor temperatures and lowering energy consumption from air conditioning — supporting Singapore’s green building initiatives.
Enhanced Security
Multi-point locking systems and hook-shaped locks embedded in the frame make hinged windows one of the most secure window types, offering strong resistance against forced entry.
Sound Insulation
The compression seal and option for double-glazed or laminated glass make hinged windows excellent for noise reduction — ideal for properties near busy roads, MRT lines, or construction sites.
Unobstructed Views & Easy Cleaning
With no centre rail or overlapping panes, hinged windows provide clear views and maximum natural light. The outward-opening design allows easy access to both sides of the glass from inside your home.
