SIGA Wigluv 20/40 Tape: 2-1/4' Wide

Special split back for exterior window sealing.

The white general usage exterior tape is the perfect choice for sealing panel joints on plywood, foam boards or OSB panels without the need for a primer. See OSB application notes below. Once applied, Wigluv is UV and driving rain resistant, and can be left exposed for 12 months. Wigluv is highly vapor permeable, reliable, and provides permenant protection for roof and facade.

A favorite of Fine Home Building's Backyard Tape Test. Download a copy of the article here.

OSB application issues: OSB varies from mill to mill across the US. In most cases, Wigluv will bond to the smooth face of OSB without issues. Please test your application and if you have doubts about the bond after 24 hrs, please prime the joint with SIGA Dockskin primer.  Once primed, Any SIGA tape will adhere to the rough surface of OSB and bond well.
