Frequently Asked Questions
A: STC (Sound Transmission Class) is a rating that measures a door’s ability to reduce airborne sound. The higher the STC rating, the better the door is at soundproofing. For example, an STC 35 door provides moderate noise reduction suitable for offices, while an STC 50+ door is ideal for recording studios and high-security applications. Understanding STC ratings is essential when selecting an acoustic door to ensure it meets the soundproofing needs of your specific space.
A: Yes! We offer a wide range of customization options, including different materials, finishes, glass panels, hardware, and custom sizes. Whether you need a unique aesthetic or specific functional requirements, we can tailor our acoustic doors to fit your project. Additionally, we provide options such as specialty veneers, custom glazing for glass doors, and integrated security features for sensitive environments.
A: Acoustic doors are designed to be installed with specific seals, thresholds, and frames to maximize their performance. While standard door installation principles apply, it is crucial to ensure a proper fit and seal to prevent sound leakage. Our team can provide guidance or professional installation services. Improper installation can significantly reduce the effectiveness of an acoustic door, so we strongly recommend working with experienced professionals to ensure the highest level of noise reduction.
A: Many of our acoustic doors are available with fire ratings ranging from 20 to 180 minutes. This ensures that your doors not only provide superior soundproofing but also meet safety and compliance requirements for various industries. Fire-rated acoustic doors are ideal for applications in hospitals, schools, hotels, and corporate buildings where both fire safety and noise control are critical. We offer a variety of models that combine high STC ratings with UL-certified fire resistance for enhanced safety.
A: The right door depends on your noise control needs, budget, and application. For moderate noise reduction, an STC 35-40 door may suffice, while high-performance environments like theaters or studios may require STC 50+ doors. Additionally, consider the material and aesthetics of the door in relation to the space where it will be installed. Our team can assess your needs and recommend the best solution based on factors such as environmental noise levels, desired privacy, and architectural style.
