MoistureLok is available on these panels
*MoistureLok is not available at all McElroy Metal facilities. Extra lead times may apply.
When the temperature and humidity conditions reach the dew point, moisture condenses on the underside of metal roofing and forms droplets of water, which can cause damage to the contents of a building.
Roof panels with McElroy's MoistureLok, provide a medium for trapping this moisture in the specially designed pockets formed in the membrane.
The material holds that moisture until conditions go back below the dew point. The moisture is then released back into the air in the form of normal humidity.
MoistureLok is the McElroy Metal trade name for the DripStop product line.
To prevent capillary or wicking action, the MoistureLok membrane should be field-treated (glazed) with heat to fuse the fibers. Glazing is a process of melting MoistureLok fibers to help prevent the wicking process. Please refer to McElroy Metal’s MoistureLok and Capillary Action flyer for more details about MoistureLok and Glazing.
Panels with MoistureLok can be lapped. To prevent wicking into the lap, we recommend the bottom two to three inches of overlapping panels and trim also be glazed.
