My friend lives on the coast in a 10th floor condo. Frequently the wind will blow hard enough that the inner opening exterior door will flex and cause an extremely loud whissle. Wind blown rain will flex the door and allow water entry into the codo. You really have to be careful during elevated winds to brace the door before opening.
Does anyone know if there is a weather strip that can cause a lap seal for the door so that when it flexes the seal will be maintained. This is a steel door.
