Ventilation System Installation and Improvement

Installing or upgrading a ventilation system is a proactive approach to ensuring good air quality. For existing garages with inadequate ventilation, consider adding exhaust fans. These can be strategically placed to remove moist air from areas prone to condensation, such as near the garage door or around water heaters. The size and placement of the fans should be calculated based on the garage’s volume and the expected moisture load. For example, a 1000 cubic foot garage might benefit from a fan with a capacity of 100 cubic feet per minute (CFM) or higher. Supplementing exhaust fans with intake vents can further improve air circulation. These intake vents can be positioned higher up on the walls to draw in fresh air, while exhaust fans are placed lower to expel stale, moist air. Regular cleaning and maintenance of both intake and exhaust vents are crucial for maintaining optimal airflow. In new garage constructions, planning for proper ventilation during the initial build is ideal. This includes designing for adequate air exchange, incorporating appropriately sized vents, and ensuring the proper location and sealing of these vents.

The Role of Insulation in Moisture Control

Insulation significantly reduces moisture buildup by minimizing temperature fluctuations. Large temperature swings cause condensation, as warm, moist air cools and releases moisture. Properly installed insulation acts as a barrier, slowing down these temperature changes and reducing the opportunity for condensation to form. Different types of insulation offer varying levels of moisture resistance. For example, closed-cell spray foam insulation exhibits excellent moisture resistance compared to fiberglass batt insulation. Choosing the right type of insulation for your garage’s climate and conditions is critical in minimizing moisture problems.
