Match the usage scenario
For residential interior framed doors, an 8mm thickness is sufficiently lightweight; frameless doors and balcony or entrance doors require 10–12mm; for high-traffic public areas, 12mm or greater is recommended to prevent wobbling or deformation.
Consider the area of the glass panel
If a single glass panel exceeds 1.5m², the thickness should be at least 8mm; if it exceeds 2m², it requires more than 10mm. Thickness must increase in proportion to the surface area to prevent cracking caused by uneven stress distribution.
Verify through actual measurement
Use calipers to measure the actual glass thickness to avoid discrepancies where the product falls short of the manufacturer's 10mm claim. Also, ensure the glass thickness matches the load-bearing capacity of the hardware to prevent the door from sagging.
Consult regulatory standards
According to the *Technical Specification for Application of Architectural Glass*, the minimum thickness for a glass door leaf should be no less than 12mm; adhering to safety standards ensures operational stability.
