R-Value of a Garage DoorWe all know that a garage door is an integral part of any home. It keeps your vehicle safe and secure, as well as your belongings. Many people don’t realize that there are multiple factors to consider when choosing a garage door for purchase or installation—one of those factors being the R-value of a garage door. 

If you are considering purchasing a new garage door, the R-value is one of the most important things to consider. This value is typically measured in units called “R” and represents how well your door insulates your home from heat loss. The higher this number, the better it will perform in keeping your home cool during the summer months and warm during the winter months. 

What Is a Garage Door R-Value?

It’s a common misconception that the R-value of a garage door is the same as the insulation. In fact, it only accounts for about 10% of your home’s energy efficiency. Learn more from this blog post! For homeowners looking to improve their home’s energy efficiency and save money on utility bills, it is essential to know what an R-value does and how it can affect your home. 

A garage door’s R-value is the standard measure of thermal resistance. The higher its R-value, the better it can stop heat flow and keep your home comfortable year-round. Be sure to check your insulation before you buy a new one or replace an old sliding door with insulated roller doors in Pittsburgh, Pennsylvania, for maximum comfort throughout the winter and summer months!

Understanding R-Values Of a Garage Door

The type of insulation a homeowner chooses for their garage door depends on the material’s R-value and its thickness. Two common materials are polyurethane foam, which is thicker but has an average R-Value of 3.3 to 6.5, or polystyrene boards that have a lower R-value at around 1 inch thick as thin as 0 inches in some cases up to 2 inches high depending on what you choose from your local hardware store.

The R-value of different types of polyurethane insulation can range from as low as R-2.5 or 3.5 to a high value up to an impressive 10, depending on the type you use. Open-cell spray foam has nearly half the R-value per inch compared with closed-cell insulation when it comes down to numbers and measurements.

The common assumption is that an R-16 door is twice as effective at insulating as an R-8 door, but this isn’t the case. With a 5% increase in effectiveness, you can expect to save about $100 per year on heating and cooling costs.

People often think that higher insulation values provide significantly more insulation than lower ones; many assume an 8 rating (R) would be half of what it takes for 16 (R). Although we do see fewer savings with increasing R-value ratings from one home to another or even within different parts of your house like ceiling vs. walls etc., there’s still around a five percent difference between them all depending upon how much heat energy they’re trying to retain/release which could save you around $100 per year.

Many people assume that R-16 is twice as good as an R-8 value. This assumption doesn’t hold much weight because a decrease in heat flow by 5% and improvement of energy efficiency by another 5% aren’t considerable gains over the original insulation effectiveness from one material to another. The difference can be seen in the table below.

There is a difference in the ways that different manufacturers report their R-values. Some will give you an entire door assembly, while others only tell you about one of its components — insulation on center panels or between two halves of garage doors. Some have reported values as low as 5 and 10 for whole units but up to 32 when given just the number from central panes alone!

Even though the center of the panel on this door is thickly insulated, it’s important to remember that other parts on a garage door could leave you exposed even with insulation in place. This includes hardware and seals around your product – all elements can’t be insulated.

Keeping the R-Value with the Climate of the Surroundings

The ideal amount of insulation for garage doors in Pennsylvania is between 14 and 16 because the climate experiences extremely hot summers and cold winters. Those living in New York or Connecticut should also get the same rating to maximize efficiency while balancing warmth throughout different seasons. On the other hand, garage doors in Maryland and Florida don’t need to have an R-value of at least R7 like states in the Northeast as they have a very moderate climate.

Benefits of Well-Insulated Garage

A well-insulated garage is an essential element in insulating your home. Garage doors are often made of metal, which gives them low insulation value. A poorly insulated garage can make it harder to maintain a consistent temperature in your house or building. Good insulation will help keep the cool air inside during the warmer months and block out heat from entering when it’s cold. A well-insulated garage will be able to maintain a more stable and comfortable temperature throughout the year.

After installing insulation on your garage door, you can expect it to: 

• Stay cool in the summer and warm in the winter

• Save money on heating and cooling costs

• Reduce noise from outside your house or building

• Increase the life of your garage door

By insulating your garage door, you can save significant amounts of energy and money. A well-insulated door reduces the amount of heating needed in a building by acting as an insulation barrier between indoor and outdoor environments. It also lowers utility bills because it keeps cold temperatures out, which prevents them from entering houses and increasing their temperature throughout the winter months. 

By saving heat during colder seasons like winter, your car battery loses power slower – resulting in fewer difficulties shifting gears.

Why Replace Your Garage Door?
