	Wet Seal System are one of the original MCM installation systems, along with dry seals, used for around 40 years in the US and still widely used today. Also known as a “single line barrier wall” or “fully-sealed wall”, wet seal systems are installed with a joint located between adjacent panels that is fully sealed with exposed sealant. Tested in the US to AAMA 501 & 501.1 standards, in the UK fire class tests will likely be according to Euroclass A1 or A2, A or B as the lower rating.

The Metal Constuction Association, Technical Bulletin Panel System Definitions, dated March 2018 defines

Wet Seal System: This was one of the original installation systems and is still widely used today in a variety of applications. Also known as a “single line barrier wall” or “fully-sealed wall”, a Wet Seal system is installed with a joint located between adjacent panels that is fully sealed with exposed sealant. This installation type creates a single barrier between the exterior environment and the interior cavity behind the panel. Air and water infiltration is minimized by the flexible exposed sealant located at each panel joint. In this type of system, the sealant installation and adhesion to the panel on each side of the joint is critical for successful performance. This type of installation should be inspected regularly to make sure that the sealant has not lost flexibility or adhesion to the panel as the exterior envelope ages.

The Wet Seal system is intended to stop water

infiltration at the exterior panel surface; however any

water or condensation that may find its way into the panel

cavity gathers at the sill flashing. A well designed Wet

Seal system will generally include the use of properly

designed sill flashings with weep tubes to allow unwanted

water to exit. The use of an air/water barrier is generally

recommended to protect the panel cavity from moisture

damage; however the wall assembly should be tested

without this additional barrier in place so that

performance of the exterior cladding assembly may be

determined isolated from the air/water barrier

performance.

Tested to AAMA 501 & 501.1 standards
