Recommended Butyl Tape And Sealant For Installing A MaxxAir RV Roof Vent
Question:
When installing a Maxxair roof fan/vent, what size butyl tape and sealant around the vent do you recommend?
asked by: Steve W
Expert Reply:
I recommend the Alpha Systems Butyl Tape for RV Weatherproofing # AL28FJ as it's 1" wide to fully cover the flange of your vent. Make sure you overlap the ends to form a tight waterproof seal. You can see me doing this at 2:50 mark in the attached video below.
As for the sealant, I recommend the Alpha Systems 1021 Self-Leveling Sealant for RVs # AL98KV. One tube of this will be enough to fully cover the screws and layer it down to the roof to ensure you don't have a water leak.

This Alpha systems tape and caulk is different than the kit your website links to, for install of the delux fan. Why the difference? Which is better and why? Thank you -
