Our two-piece vent block, which includes the block and screen, is a smart choice when you need effective cross-ventilation in garages, foundations, and range hoods. Our precast concrete blocks are available in a range of shapes, designs, and sizes, built to last through the years enhancing the appearance of your building while providing your first line of defense against moisture, musty air, and debris.

Reinforced with a galvanized frame, our concrete vent blocks will allow trapped moisture to exit, maintaining adequate circulation of fresh air beneath your home or any other structure. Our vent blocks are designed to cut heavy winds without blocking circulation of air, with decorate louvers available in one solid piece for decorative use only.
