For many Escondido homeowners, the garage is more than just a place to park cars. It's a workshop, storage space, home gym, or even a hangout area. But without proper insulation, your garage can be an energy drain.letting hot summer air and cool winter air affect your home's overall temperature. At Garage Door Escondido, we've helped countless homeowners improve their energy efficiency with insulated garage doors. Here's what you need to know.
Your garage door is likely the largest opening in your home. A single-car door typically measures about 7x8 feet (56 square feet), while a double-car door is around 16x7 feet (112 square feet). That's a lot of surface area that can transfer heat.

In winter, it may drop to near-outdoor temperatures. This affects: - Rooms above or adjacent to the garage, Your HVAC system's workload, Items stored in the garage, Comfort when using the garage
R-value measures insulation's thermal resistance.its ability to resist heat flow. Higher R-values mean better insulation.
R-Value Guidelines for Escondido: - R-6 to R-9: Good for mild climates, basic energy improvement - R-12 to R-16: Better for year-round comfort, attached garages - R-16 to R-18+: Best for conditioned garages, living spaces above
