How To Choose The Right UPVC Windows for Apartment Projects

In overseas apartment projects, window systems not only affect building aesthetics but also determine ventilation, natural lighting, and long-term maintenance costs. For overseas window and door distributors, selecting the right uPVC window type is a crucial factor that impacts project deliverability, client satisfaction, and profit margins. This guide provides practical advice to help you quickly identify which uPVC windows are most suitable for apartment projects, combined with actionable recommendations based on our brand VIGORAWINDOWS’ manufacturing experience.

Why Apartment Projects Require Structurally Stable uPVC Windows

Unlike villas or detached houses, apartment projects typically demand higher consistency, weather resistance, and safety from windows. For example, in the high-temperature environments of the Middle East, or the humid climates of Africa and Southeast Asia, profile stability directly affects service life.

According to India’s Central Public Works Department – Technical Guide on Window Systems (2023):

“In tropical regions, uPVC window system with insufficient profile stability are prone to deformation and seal degradation under prolonged high humidity, so the supply chain must utilize high-grade weather-resistant formulations.”

This aligns with our experience in overseas projects. In apartment projects in the Middle East or Africa, distributors often prefer fixed uPVC windows for their structural simplicity and low maintenance, while using operable windows as needed for ventilation.

Common Window Types and Their Selection Logic

In apartment projects, choosing the right window is less about “the most expensive” and more about “the most suitable.” The following three types are widely used globally, each with distinct advantages.

1. Casement uPVC windows — Ideal for Apartments Prioritizing Sealing

Casement uPVC windows feature outward or inward opening mechanisms with evenly distributed seals, offering excellent airtightness and water resistance, suitable for:

• Coastal or rainy regions

• Energy-efficient modern apartments

• Mid- to high-rise buildings (higher wind pressure)

According to Singapore’s Housing & Development Board (HDB) Material Performance Specification – 2022:

“Outward-opening uPVC windows show significantly better energy performance per unit area compared to side-swing models, making them ideal for humid and monsoon-prone buildings.”

VIGORAWINDOWS provides multiple hardware options, including multi-point locking systems, mosquito screens, and weather-resistant seals, ensuring casement windows maintain high stability across countries.

2. Fixed uPVC window — Economical and Stable Choice for Apartment Facades

Fixed uPVC windows cannot open and are commonly used for:

• Facade design

• Stairwells

• High-rise safety zones

• Large curtain wall areas

Their main advantages are lower cost, high sealing performance, and zero maintenance, making them ideal for large-scale projects.

We offer fixed windows in standard or custom sizes, allowing developers and distributors to control costs while maintaining visual consistency.

3. Tilt and turn uPVC windows — Versatile Ventilation for Mid- to High-End Apartments

Tilt and turn uPVC windows combine inward-opening and tilt-in ventilation, suitable for:

• High-end apartment projects

• European-style buildings

• Families prioritizing safe ventilation

Advantages:

• Tilt function allows safe ventilation

• Reduces heat loss in winter

• Better sealing than most sliding windows

This type has seen growth in South America and Eastern Europe, meeting functional demands for premium projects.

Large Apartment Projects Benefit from Custom uPVC Window Systems

In real projects, standard sizes often cannot meet architectural designs. Many overseas distributors prefer custom uPVC windows.

Customizable features include:

• Glass types (Low-E, laminated, insulated)

• Profile colors (white, gray, wood grain，custom)

• Hardware systems (European, Middle East, Africa compatible)

• Anti-theft structures and mesh screens

• Large floor-to-ceiling window structures

According to Malaysia CIDB’s Industrialized Building Component Performance Report 2023:

“Customizable window systems significantly improve construction efficiency and facade consistency in apartment projects.”
