How Interior Doors Reduce Sound Transmission


Your dishwasher shouldn’t be quieter. Better-performing interior doors reduce sound transmission!

How often are you irritated because you can hear your dishwasher or washing machine in the next room? Or maybe you’d like not to hear your teenager’s loud music? What if many of the sounds you’d like to block could be significantly minimized just by upgrading your interior doors? Well, that’s certainly a possibility.

In this post, you’ll learn how interior doors reduce sound transmission.

How sound travels

When sound comes into contact with a barrier like an interior door, some of the energy from the vibrations transfers to the door. The resulting vibrations in the door then set the air in motion, creating sound on the other side of the door. The mass and stiffness of the barrier impact how much sound will transfer.

Thus, the inside of your interior door is critical when considering noise reduction.

Why your interior doors matter

Busy homes or active areas create a lot of noise. However, you’d probably like to keep that noise confined to its space. Upgrading your interior doors is a budget-friendly, easy solution. You’ll want to determine the Sound Transmission Class (STC) and/or the OITC (Outdoor-Indoor Transmission Class). You can read more about STC and OITC in our blog.

Once you’ve determined what your level of sound reduction is, then you can review all the doors that meet those requirements. We offer ProCore® solid cores for all molded doors as an upgrade. This can reduce the transmission of sound by up to 50 percent compared to a hollow core door.

Our TRIA™ interior doors are carved from composite wood and have a solid core. The TRIA collection doors have the highest STC ratings of all our interior doors.

Where better interior doors will benefit you the most

Where to install higher-quality interior doors depends on the layout of your space as well as what occurs in it. We’ve discussed the annoying sounds of a dishwasher and washing machine. If your home has its own laundry area, install a solid core door here to reduce the myriad of sounds. Kitchens are typically open spaces now, so it might be harder to ignore the dishwasher.

They also make sense in bathrooms or bedrooms. Again, these are noisy areas, so a great solid door in a child’s bedroom will hopefully keep him or her asleep. For bathrooms, eliminate noise related to plumbing and the blow dryer.

By reducing the transmission of sound throughout your home, you can create a better experience for each of your spaces. And interior door upgrades are certainly not a blow-the-budget kind of upgrade. It’s worth checking out some better doors if the noise in your space is impacting your quality of life.

We invite you to review all our interior doors. Better interior doors reduce sound transmission, providing you a more serene environment. Just another way that JELD-WEN is here to make your possibilities come true.

Old World Interior Doors


If you’re designing for Old World style, don’t forget about your interior doors. Interior doors don’t have to be plain or boring. Old World interior doors can have a carved appearance, raised panels and other details. There are many options that offer great appeal. There are several benefits associated with how a composite wood door is made. In this blog, we’ll take a look at those.

Benefits of wood composite doors

In addition to adding style, interior doors can offer other benefits. First consider the materials. Deriving doors from composite wood, an engineered wood product made from wood fibers, can provide better performance than wood. Composite wood doesn’t react to humidity the way that all-wood doors do. It resists bowing, splitting and warping. Composite is also more durable. It can withstand the daily abuse that an interior door must take. This type of core also helps to block out sound so when closed, any room can be a quiet room.

The look of wood composite doors

Because composite doors aren’t all-wood, there’s no visible grain or imperfections to bleed through the paint. These painted doors will look great for years.

Creating Old World interior doors

Old World style is a blend of hard and soft; formal and comfortable. Carvings and details are found throughout homes in patterns, on furniture and of course on doors. Composite doors can be finished with a carved appearance. There are a variety of patterns to customize the look. Complement the etchings in your mantle or the intricacy of your molding in your interior doors.

First you would choose your profile, which can be wide or narrow. Then decide how intricate you want the door. Panels can be raised or inlaid. Dramatic contours make a statement. Complete the look by choosing a color for your door. Old World color patterns are known to be rich and regal. Colors are often dark like burgundy, navy or forest green. Ocher and cream are lighter. Really, the choice is up to you and how much you want your Old World interior doors to stand out.
