Wind loads and weather testing

Weather testing on bi-fold doors is an important aspect to ensure that the doors can withstand different weather conditions, such as rain, wind, and extreme temperatures. This testing is typically performed to evaluate the durability, safety, and performance of the doors.

Water infiltration testing involves exposing the bi-fold doors to a controlled amount of water for a specified period, typically using a spray rack or shower apparatus. The doors are inspected for any signs of water leakage, such through the glazing, gaskets or frame.

Wind load resistance testing involves subjecting the doors to a series of wind gusts and pressures that simulate various wind speeds and directions. The doors are then evaluated for their ability to resist deformation, deflection, and damage from the wind loads, including those up to hurricane levels.

Thermal testing

Thermal testing on a bi-fold door typically involves measuring the door’s thermal performance, which is its ability to resist heat transfer.

This test is crucial because it provides insight into how well the door will perform in terms of energy efficiency.
