HVACQuick Ventilated Frieze Blocks

A well-built eave is attractive, keeps rain from the walls, and provides a sheltered space in which to install attic ventilation. Unfortunately, like all vents, soffit and frieze block vents also provide a vector for pests to potentially enter the home. HVACQuick is proud to offer its own line of superior ventilated frieze blocks. Ideal for open-eave construction and manufactured exclusively for us, these superior products let air into, and keep pests out of, the attic better than any available alternative.

All-aluminum construction
Manufactured in the USA
