The common low window sill is about 0.5 meters away from the ground. If the 0.4 m guardrail or fence is added close to the inner wall, the protective measures required by the specification must be met. If the window sill is too large, such as a bay window, the child often stands on the window sill and the user must stand on the window sill to open the window. At this time, the height of the guardrail attached to the window sill should be 0.9 meters.
The net height of the guardrail should not be less than 1.05 meters. The net height of guardrails for middle and high-rise and high-rise residential buildings should not be less than 1.1 meters. It is 0.9 meters higher than the window guardrail.
