In our years serving Broadbent, we've seen this problem again and again: homeowners lose hundreds of dollars annually through an uninsulated or poorly insulated garage door. An uninsulated door acts like an open window in winter and summer alike. If your garage door has no insulation, or only a thin layer, your heating and cooling system works overtime to regulate the temperature inside.and attached homes lose conditioned air directly into the garage.
Your garage door is one of the largest moving parts of your home's envelope. In Broadbent's climate, winter temperatures dip well below freezing, and an uninsulated door lets that cold seep into your garage, workshop, or even into adjacent living spaces if your home is attached to the garage. The same goes for summer heat. An insulated door slows that transfer significantly.
The R-value is the measure of thermal resistance.higher numbers mean better insulation. Most quality insulated garage doors carry an R-value between 8.8 and 18.4. That number tells you how effectively the door resists heat flow. A door with no insulation has an R-value of zero. The difference in your monthly energy bills can be 15,25% lower when you upgrade to a properly insulated door, depending on usage and local utility rates.
Beyond energy savings, insulation also dampens noise. A heavier, insulated door operates more quietly than a hollow steel or aluminum door. If you park inside or use the garage as a workshop, that's a real quality-of-life improvement.
Think of your garage door as a thermal weak point. In winter, warm air from your home's heating system migrates into the garage and then straight out through the door's surface. In summer, outdoor heat radiates through an uninsulated door into your garage, forcing your air conditioning to compensate. Over a heating season in Oregon, this cumulative heat loss adds up fast.
An insulated door with polyurethane or polystyrene foam core interrupts that transfer. The foam acts as a barrier, trapping air pockets that resist temperature change. Polyurethane foam is slightly more efficient than polystyrene and also provides better structural rigidity, but both options outperform no insulation by a wide margin.

If your current door is damaged or nearing the end of its life, replacing it with an insulated model is the cleanest solution. New insulated doors range from $600 to $2,500 depending on size, material, and R-value. We provide a free estimate so you know the exact cost before any work begins.
If your door is still structurally sound, you have another option: adding insulation to your existing door. Insulation kits are available and can be applied to single-layer or older doors. This is a more affordable route.typically $150,$400 for materials and labor.and can extend your door's useful life by several years while cutting energy loss immediately.
