VILPE Airidge Felt Ridge Vent is suitable for installation on the ridges of residential roofs and can adapt to roof pitches up to a maximum of 45°. The roof ridge is opened at the location of the vent, and the vents are installed sequentially using built-in connectors. The ridge vent is fastened to the substructure by screwing through pre-drilled holes. To ensure the vent is attached securely, ridge shingles should be nailed over the vent along the nailing line.
