Planning to convert your garage to living space? One of the most critical steps—especially in Portland’s damp, chilly climate—is ensuring your new space is properly insulated and heated. Without it, your converted garage will be cold in the winter, hot in the summer, and uncomfortable year-round.
In this guide, we’ll cover what it takes to insulate and heat a garage conversion effectively and how the experts at Boss PDX help homeowners in the Portland area turn their garages into cozy, code-compliant living spaces.
Why Insulation Is a Must for Garage Conversions
Garages aren’t built like living rooms. They usually lack insulation in the walls, ceiling, and garage door—meaning they don’t retain heat or block out cold. When you convert a garage to living space, adding insulation is essential to meet Oregon energy codes and provide year-round comfort.
Key Areas to Insulate:
- Walls: Fill the stud cavities with fiberglass or spray foam insulation before drywall installation.
- Ceiling: Insulate between joists—especially if there’s a room above or exposed roof.
- Garage Door: Replace with a wall or use insulated panels if keeping the door in place.
- Floor: Add rigid foam board beneath a raised subfloor or use an insulated concrete overlay.
Heating Options for Your Garage Conversion
Once your space is sealed and insulated, it’s time to think about heating. Portland’s winters require a reliable system to keep your new living space cozy and safe.
Popular Heating Solutions:
- Mini-Split Heat Pump: Highly efficient, easy to install, and provides both heating and cooling.
- Radiant Floor Heating: Ideal for new concrete pours or tile installations, especially in bathrooms or ADUs.
- Electric Baseboard Heaters: Simple and cost-effective for smaller conversions.
- Extending Existing HVAC: Can work if your home’s system is properly sized and ductwork allows.
Tip: Always install a programmable thermostat to keep your energy use efficient and predictable.
Don’t Forget Ventilation
Insulating your garage creates a sealed environment—so you’ll also need proper ventilation. A heat recovery ventilator (HRV) or exhaust fan may be necessary, especially if your garage conversion includes a bathroom or kitchenette.
