Being an integral part of your home architecture, doors are vital for aesthetic purposes, giving entry and exit points, privacy, and as a barrier to noise. The latter is especially important in today’s noisy world. The ability of a door to block noise is given a value using different rating systems such as Rw rating and STC. This is the cradle of the debate – Rw rating vs STC bifold doors – which we’re going to demystify today.
Rw (Weighted Sound Reduction Index) rating and STC (Sound Transmission Class) are two metrics used to measure the degree to which sound is blocked by a barrier, in this case, the door. If you’re keen to understand these ratings and their implications in the selection of bifold doors, then you’re in the right place. Our discussion will give you an informational insight into noise rating comparisons and acoustic door standards.
Before we delve into the juicy details of comparing Rw rating and STC for bifold doors, let’s get the basics right.
The Rw or Weighted Sound Reduction Index is a rating system widely used in Europe to measure the sound insulation property of a material. The value ranges from 0 to 100, wherein the higher the value, the better the material is in blocking the transmission of airborne sound.
STC, on the other hand, stands for Sound Transmission Class, a standard predominantly used in North America. Like Rw, it measures the effectiveness of a door or other barriers in preventing sound transmission. An STC rating can show how well a door can reduce noise from everyday activities like conversation, or louder sounds like musical instruments or a running engine.

Conflicting claims and marketing hype can make it difficult to choose between doors with Rw ratings and those with STC. How do you compare these two distinct ratings? Let’s find out.
Both Rw and STC ratings quantify how well a particular bifold door will prevent the transmission of sound. Both ratings are based on laboratory tests conducted under controlled conditions.
The primary differences lie in the types of sounds the ratings focus on. STC tends to be more focused on human voice frequencies, while Rw considers a broader range of frequencies. Consequently, a door with a high STC might be excellent at blocking out chatter but not as effective against lower-frequency noise such as traffic or music.
When it comes down to selecting a door based on Rw rating or STC, you must consider the kind of noise you’re trying to block. Understand what sound frequencies you are most concerned about and choose the door with the rating that best addresses your needs.
As STC is ideal for dealing with sounds within the speech frequency range, it might be your best choice if you’re looking to reduce noise from conversations or high-pitched sounds.
However, if you’re dealing with mixed noise types, or sounds at lower frequencies, considering Rw-rated doors might be a more practical decision.
Florida is known for its vibrant life, picturesque beaches, and unfortunately, hurricanes. In areas like Miami-Dade, where the risk of hurricanes is high, building codes require stringent standards, requiring doors not only to perform acoustically but also to withstand high winds and impact.
In Miami-Dade, Florida, the building codes for doors also factor in elements like noise control and acoustic efficiency. Therefore, when selecting doors, residents often need to ensure that they meet the acoustic door standards recommended for the state.
Understanding and comparing Rw rating vs STC bifold doors is pivotal when deciding on the best doors for your home or office. Remember, the best door for you depends largely on the nature of the noise you are trying to block. Both Rw and STC rated bifold doors have their merits and the optimal choice will significantly enhance the quiet and comfort of your living or working space.
