SLP Plastic Slant-Back Static Vents

UL 2218 Class 4

The SLP vents are Air Vent's slant-back plastic static roof vents: the SLP61, with a 16.5 x 19.5 in. flashing, 9 in. square opening and 61 square inches of net free area per vent, and the SLP150, with a 21.5 x 25 in. flashing, 13 in. square opening and 150 square inches per vent. The 2026 ventilation catalog prints a rust-free insect screen and a UL 2218 Class 4 Impact Rating for both. The catalog also prints a limited lifetime warranty for both, while Air Vent's June 2025 warranty chart lists roof louvers and static vents under a 5 Year Limited Warranty; the two documents disagree.
