Be a decoration expert aluminum window purchase installation points
As traditional steel and wooden windows gradually fade from the home improvement scene, aluminum alloy and PVC windows have taken center stage in the market. With a wide variety of materials available, it's essential for consumers to understand how to properly identify and purchase quality aluminum alloy windows. In this article, we’ll walk you through the key steps to buying and installing aluminum alloy windows effectively.
Part 1: Choosing the Right Type of Aluminum Alloy Windows
There are numerous types of aluminum alloy windows on the market, ranging from basic models to more advanced options like wood-aluminum composite systems. Before making a purchase, it’s important to plan out the window type that best suits your home. Consider factors such as opening style, design preferences, and functional needs.
Types Based on Opening Mechanism
Aluminum alloy windows can be categorized based on their opening mechanisms into four main types: fixed windows, casement windows, sliding windows, and tilt-and-turn windows. Fixed windows are fully sealed and ideal for areas where ventilation is not needed. Casement windows offer excellent ventilation and save space, while sliding windows take up less room but may compromise on sealing and airflow.
Types Based on Profiles
Aluminum profiles come in two main categories: standard aluminum and thermally broken aluminum. The latter offers superior thermal insulation, addressing the common issue of poor heat retention in traditional aluminum frames.
Types Based on Thickness
Common aluminum alloy thicknesses include 40mm, 45mm, 50mm, 60mm, and beyond. The choice depends on the overall design and structural requirements of your home. It's important not to choose blindly—consider the aesthetic and functional needs of your space.
Advantages of Aluminum Alloy Windows
Compared to traditional materials, aluminum alloy windows are lightweight, durable, and offer excellent air and water tightness. Thermally broken aluminum also provides better insulation, contributing to energy efficiency and long-term cost savings. These features make them a popular choice for modern home improvements.
Part 2: Mastering the Buying Process
Purchasing aluminum alloy windows involves careful planning and informed decision-making. Understanding the material properties and knowing what to look for can help you make a smarter choice. Here are some tips to guide you through the selection process.
Check the Appearance
Inspect the surface of the aluminum profile. A high-quality product should have a smooth finish without visible damage, color inconsistencies, or imperfections like chips, burrs, or oil stains.
Measure the Thickness
Residential aluminum windows typically come in sizes like 55mm, 60mm, 70mm, and 90mm. Thicker frames generally provide better wind resistance. For balcony windows, it's recommended to choose at least 70mm thick profiles for durability and safety.
Test the Strength
Qualified aluminum alloy should have a tensile strength of at least 157 Newtons per square millimeter. You can test the flexibility by gently bending the frame and checking if it returns to its original shape without deformation.
Examine the Oxidation Layer
A good aluminum alloy window should have an oxide layer of at least 10 microns. To check, gently scratch the surface and see if the oxide layer can be easily removed. If it does, the material may not be of high quality.
Part 3: Installation Tips for Perfect Results
The installation of aluminum alloy windows requires attention to detail to ensure proper function and longevity. Following the correct procedures will help you achieve a seamless fit and improved performance.
Determine the Position
Before installation, refer to the architectural drawings and mark the exact position of the window. Use tools like plumb lines or theodolites to ensure accurate alignment, especially for the top edge of the window.
Waterproofing and Corrosion Protection
Install weatherstripping as specified in the drawings, and apply anti-corrosion treatment to the outer surface of the window frame. Use stainless steel fasteners to prevent electrochemical reactions and ensure long-lasting performance.
Fixing the Window Frame
Once the positioning is confirmed, install and secure the window frame. If embedded iron pieces are present, weld the window frame directly to them. Otherwise, use metal expansion bolts with plastic anchors and ensure proper rust protection after welding.
Gap Filling and Sealing
After installation, fill the gaps between the window and the wall with elastic insulation material or glass wool. Seal the outer edges with a 5-8 mm deep groove using a high-quality sealant for optimal weather resistance.
Part 4: Final Inspection and Acceptance
Once installed, a thorough inspection is crucial to ensure everything is functioning correctly. This step helps avoid future issues and ensures the window integrates well with your home’s design.
Check the Appearance
From a distance, inspect the window’s surface for even color, no deformations, cracks, or scratches. A visually appealing and well-maintained window reflects quality craftsmanship.
Check the Sealing
Ensure the rubber gasket is smoothly aligned with the glass channel, without curling or gaps. The gap between the gasket and the frame should not exceed 1mm for a tight seal.
Inspect the Frame Alignment
Check the vertical flatness of the window frame and the connection between the window and the wall. Use a mirror and telescopic tubes to test the tightness of the joints and confirm the window is properly installed.
Comments: While installing aluminum alloy windows may seem straightforward, there are many details to consider. By paying attention to each step during the installation process, you can ensure a smoother transition into your new home with greater peace of mind.
