Sealant Joints: Don?t Ignore this Small Component and its Big Mission [Pushing the Building Envelope]

Excellent post by Christopher Matthews of Glazing Consultants International, LLC on the topic of sealant joints. He describes a common scenario where water intrusion is reported near windows and doors, only to discover that sealant is failed or missing at exterior joints.

It should not take a rocket scientist or even an envelope consultant to determine that open exterior joints can allow large amounts of water into the wall system at these locations, but for many owners, a consultant is required.
