A new technique to identify sealant failures on building exteriors has been introduced by Global Prevention Services.

The majority of modern commercial buildings employ design techniques that utilize exterior walls as non-structural (non-load supporting) “skins.” This skin is functionally designed to control and limit air and water passage. Connecting each piece of the skin is a flexible seal designed to prevent the free passage of air and water. Most of these buildings are sealed with hand-applied sealants. It is almost impossible to install all the sealants perfectly and imperfect building seals allow air and water to enter and escape from buildings. SealTests allows for a cost effective scientific solution to identify sealant failures, the company said.
