Bonus Room Comfort

Make Your Room Over Garage Comfortable Year-Round

Rooms built over garages are often uncomfortable. They can be freezing in winter and sweltering in summer, making them challenging spaces to use.

Spray foam insulation creates a powerful air seal and thermal barrier, helping to make these areas consistently comfortable.

Why Rooms Over Garages Are Uncomfortable

Garages are often unconditioned spaces, meaning they aren't heated or cooled. This lack of insulation and air sealing allows extreme outdoor temperatures to transfer directly into the room above. Without a proper barrier, air leaks are common, leading to drafts and significant temperature fluctuations. Addressing this requires a robust insulation and air sealing solution like spray foam.

The Challenge of Bonus Room Temperatures

Many Atlanta homeowners find their bonus rooms over garages are either too hot or too cold. This is often due to the lack of a proper thermal envelope. Unlike the main house, the garage below is typically unconditioned, exposing the floor of the room above to outside temperatures. This can lead to uncomfortable living or working spaces.

How Spray Foam Solves the Problem

Spray foam insulation acts as both an insulator and an air barrier. When applied to the ceiling of the garage or the walls of the bonus room, it seals tiny cracks and gaps that allow air to escape or enter. This prevents temperature transfer and helps create a stable, comfortable environment within the room.

Benefits Beyond Comfort

Beyond making the room usable, properly insulated rooms over garages contribute to overall home energy efficiency. By reducing the workload on your HVAC system, you may see lower energy bills. It can also help reduce noise transfer from the garage below.

Preparing for Insulation

Before insulation, ensure any necessary electrical or plumbing work in the ceiling or walls is completed. Verify that the space is free of debris. For older homes, check for any existing moisture issues in the garage or subfloor that may need addressing by a qualified professional before sealing the space.

Improving Your Room Over Garage

  • Assess current temperature and draft issues.
  • Inspect for any moisture or structural concerns.
  • Ensure all utility work is finished.
  • Clear the area for access.
  • Consider spray foam for air sealing.
  • Verify ventilation needs for the bonus room.
  • Confirm local building codes for insulation.
