Moisture-Resistant Wall Construction

Walls are an integral part of a structure's water and weatherproofing system. Details in wall design and construction are important in preventing damaging moisture build-up, whether the moisture originates from outside or inside the building. Care in wall design, particularly around window and door openings, can prevent damaging moisture build-up.
