Marco’s 45 Intake Vent is engineered to deliver efficient attic ventilation by allowing fresh air to enter at the roofline, promoting proper airflow and helping extend the life of the roofing system. Made from durable no-break polypropylene, this intake vent is designed to perform in tough conditions while staying lightweight and easy to install. With a low-profile design and compatibility with roof slopes from 3:12 to 16:12, it provides a clean finish without sacrificing performance.
By introducing balanced intake airflow, the 45 Intake Vent supports a healthier roofing system by reducing heat buildup and moisture accumulation that can lead to structural damage and higher utility costs. Its durable composition withstands harsh weather and pressure conditions up to -75 psf, while screened and filtered options help block debris and pests. Fast installation and code approvals make it a reliable choice for contractors looking to minimize callbacks and deliver long-term performance.
