Key Performance Indicators of Doors & Windows You Must Know: Sound Insulation, Heat Insulation and Anti-Theft

1. Anti-theft performance: The core of the main entry door

• Cold-rolled steel doors with a thickness of ≥1.2mm for the door leaf and ≥1.5mm for the door frame are the basic standard for anti-theft;
• The anti-pry time of qualified security doors is not less than 30 minutes, and the anti-pry hardware (anti-pry bolts, reinforced lock plates) is the key auxiliary part.

2. Heat insulation performance: The key of energy-saving doors and windows

• The U-value of energy-saving doors and windows for cold regions is required to be ≤1.2 W/(m²·K);
• Aluminum alloy doors with broken bridge profiles and steel doors with thermal insulation filling layer can significantly improve the heat insulation performance, which can save 30%-50% of air conditioning/heating energy consumption for homes and offices.

3. Sound insulation performance: The guarantee of space comfort

• Steel doors with solid structure and rubber sealing strips have better sound insulation effect;
• Aluminum alloy double doors with hollow glass and stainless steel screen can achieve both sound insulation and ventilation.
