Why Choose UPVC Windows | Benefits, Myths and Buying Tips

UPVC windows, with their superior thermal insulation, sound insulation, sealing, corrosion resistance, and high cost-effectiveness, have transformed from a "cheap alternative" into one of the mainstream choices for modern building windows, driven by energy-saving policies, consumption upgrades, and industry competition.

For most ordinary family homes, UPVC windows are a practical, economical, and comfortable choice. By selecting high-quality profiles, hardware, and glass, and ensuring professional installation, they can provide a warm, quiet, energy-efficient, and long-lasting comfortable living environment.

Over the past decade, thermally broken aluminum windows have dominated the market, but product homogenization has led to fierce competition. Window and door companies urgently need new growth points and differentiated products. UPVC windows, with their unique advantages, have become a key focus for many brands (such as Fuxuan and Senying), who have invested heavily in introducing advanced German technology and equipment to create "new PVC windows" and enhance quality and brand image.

Early PVC windows did indeed give the impression of being "prone to aging and deformation," largely due to insufficient profile thickness and outdated formulas resulting from low-price competition. Today's UPVC doors and windows have undergone a fundamental transformation:

• Formula Upgrade: Utilizing more stable UPVC raw materials and additives significantly improves weather resistance and impact resistance.

• Structural Optimization: Multi-cavity structure and internal steel reinforcement design solve strength and rigidity issues.

• Process Innovation: Introducing advanced European automated production lines and welding processes results in higher precision and more stable quality.

• Hardware Matching: Collaboration with high-quality hardware brands (such as Roto and Siegenia) enhances overall lifespan and user experience.

Practical Tips for Purchasing UPVC Windows

1. Focus on Profile Quality:

* Profile Wall Thickness: The minimum measured wall thickness of the visible surface of the main profile should not be less than 2.5mm. Too thin a thickness will affect strength and lifespan.

* Internal Steel Reinforcement: Check whether the profile has an internal galvanized steel reinforcement. The thickness and assembly method of the reinforcement are very important. 1. **Branded Frames:** Prioritize well-known domestic frame brands (such as Kron, Conch, and Shide) or imported brands (such as VEKA and REHAU).

2. Emphasis on Hardware:Hardware is the "heart" of the window. Choose internationally renowned brands such as ROTO, Siegenia, and G-U, or top-tier domestic brands, to ensure smooth and flexible operation for decades.

3. Crucial Glass Selection:Choose according to your needs: Insulating glass (basic configuration), Insulating glass + Low-E glass (better thermal insulation), Laminated insulating glass (better sound insulation and burglarproofing), Vacuum glass (ultimate thermal insulation).

4. Key to Sealing Strips:Use EPDM rubber sealing strips, which are elastic, resistant to aging, and less prone to cracking. Multiple sealing designs significantly improve airtightness and watertightness.

5. Installation Techniques Determine the Final Effect:Installation is 70% of the final result and 30% of the quality. The installation must be carried out by a professional installation team to ensure that the installation is horizontal and vertical, the filling is full, and the sealant is evenly distributed; otherwise, all performance will be greatly reduced.
