Does attic over garage need insulation?

If you have an attic over your garage, you might wonder whether it needs insulation. This is often an overlooked space. In many homes, the garage has a common wall with the living area of the home, and it’s essential to insulate this wall to keep cold air from transferring into the house

. Even if your garage doesn’t have a garage door, you should consider insulating the ceiling, which is in between the decking and the ceiling of the garage.

To do this, you can either buy foam or drywall. Both materials will provide insulation for your attic, and you’ll need to measure and cut each piece to fit. Once you’ve measured, you can install the insulation.

Depending on the size of the attic, you can purchase low-expanding or high-expanding foam. You should also buy drywall, which uses the same measuring technique and buying recommendations as insulation.

When cutting the insulation, use gloves, and use a wooden guide to cut it to size.

What is the best insulation for a garage attic?

The most basic type of attic insulation is fiberglass, which comes in long blankets and precut batts. This type is good for attics that are finished above the ceiling, but isn’t quite as durable as blown-in insulation.

For an attic space above a finished ceiling, consider using paper-faced fiberglass bats, which are wrapped in plastic film to give the walls a smoother appearance.

Finally, opt for encapsulated fiberglass bats, which don’t expose fibers to the exterior of the walls.

When installing loose fill insulation, measure the area by square footage and depth. You can use a depth guide to ensure uniformity. You can purchase a precut bag, then cut it to size with a utility knife.

Be sure to keep an extra bag on hand, just in case you run out! If you’re using batts and rolls, measure by length and width. Once you have a rough estimate, buy the appropriate number of insulation.

How thick should garage attic insulation be?

Before you start the insulation process, you must address any attic flaws that may hinder proper installation. These issues include under-insulated vent pipes, awkward fixtures, and air leaks. All of these factors can diminish the effectiveness of the insulation.

Here are some tips to help you determine how thick your garage attic insulation needs to be.

The R-value of garage insulation should be the same as that of your house attic. It should be R-38 to  49 to be effective. The recommended R-value varies depending on climate.

Generally, in the Chicago region, R-38 insulations are required. Insulation materials are often listed by R-value per inch of thickness.

If you live in an area with hot summers and cold winters, you’ll need thicker insulation than if you live in an area with milder weather. The second factor is the type of insulation you’re using.

Fiberglass insulation, for example, is available in different thicknesses. The third factor is the R-value of the insulation. The R-value is a measure of an insulation’s ability to resist heat flow.

How much insulation do I need in garage attic?

Insulating your garage attic is important for several reasons. For starters, it will prevent heat from escaping from your garage. Because garages are usually not insulated, they may need more than you think.

There are two types of faced insulation: bare and faced. Faced insulation is the more expensive type. It is usually non-combustible, while bare insulation is more expensive.

Some building codes require faced insulation. Find out which type of insulation your local building codes require. Find out more about the R-Value of insulation in your area by checking with Johns Manville.
