Garage door insulation can have far-reaching benefits, whether it’s hot or cold outside. Insulation provides a thermal boundary. It can maintain conditioned indoor air, which is beneficial whether you have an attached garage and rooms adjacent to the garage space, or a detached garage where a variety of activities may take place inside.
Insulation has long been known to improve energy efficiency. Although construction standards don’t completely address air leakage in garage spaces, insulated garage doors can benefit you during any season, for the following reasons:
Make the Garage Suitable as an Indoor Workspace
Insulation keeps in cooled air; it can also raise the indoor temperature over 20°F compared to outside. This can mean the difference between a chilly room and one comfortable to work in. Homeowners use their garages for everything from DIY workshops to complete home offices. Garage door insulation can keep out blistering heat and freezing cold, so you can work more comfortably and productively.
A Cold Garage Can Transfer Cold Air to Adjacent Rooms
Cold air can seep in through gaps in the garage door. It can also transfer through walls to rooms next to the garage. If your thermostat is set to a comfortable temperature, your HVAC system will have to work harder to maintain that setting. You might have a hard time achieving any comfort. This scenario not only wastes energy; it also strains your heating system to the point it can break down much sooner than expected, meaning you’ll have to pay to fix or replace it potentially years earlier than necessary. At the very least, you’ll likely have higher energy bills.
Your Car Is Protected in Freezing Weather
Freezing conditions can shorten car battery life, lower air pressure in tires, and cause engine, transmission, and brake fluids to thicken. Spark plugs and wiring can be negatively affected as well. An insulated garage door can therefore help your car run more reliably. Extreme heat can be a problem as well, as it can damage tires and batteries and shorten the life of engine oil and coolant. Also, fuel evaporates faster in high heat, so an insulated garage can contribute to improved fuel economy.
Your Storage Is Better Protected
Whether you store paint, oil, or even food or beverage products in your garage, protecting them from temperature extremes can keep them viable. A garage is a convenient place to store utility items. Paints, oils, and, other goods have recommended storage temperatures to maintain their quality. If you store perishable food items, improper temperatures will lead to spoilage, so you could be wasting them without knowing it.
Tools and Equipment Can Last Longer
Car batteries work best in temperatures between 30 and 90°F. Temperature extremes affect other mechanical components as well. If liquids in a lawnmower or power washer freeze, the equipment can be damaged beyond repair. Components in power tools can be affected by extreme temperatures as well.
In-Garage Refrigerators Can Work More Efficiently
Refrigerators are typically designed to operate in a moderate temperature environment. In extremely hot conditions, a refrigerator will require more effort to keep things cold, which can wear out critical components such as the compressor. Freezing outside temperatures can cause the refrigerator to reduce its workload to the point the freezer thaws out. Moderate temperatures enable the appliance to work more efficiently.
