Structural Stability & Acoustic Comfort
Our Straviwood acoustic isolation solutions are specifically designed to address the unique challenges of CLT and modular construction. With our state-of-the-art materials and techniques, we can provide excellent sound isolation between rooms. Our solutions are customizable and can be tailored to meet the specific needs of your project, ensuring that your building is not only sustainable but also functional and comfortable.
The primary reason for poor acoustic isolation in CLT construction is due to the low weight of the panels. Although CLT panels are thicker than traditional timber boards for structural applications, they are still much lighter than concrete or masonry. This means that they do not provide as much mass to attenuate sound transmission. In addition, the typical use of steel plate and fastened connections in direct contact with the panel, facilitates sound vibration via flanking sound transmission.
Acoustic comfort is an important consideration, generally regulated by European national standards, particularly in multi-family, educational and commercial buildings where noise can be a significant issue and additional sound insulation measures may be necessary to meet specific acoustic requirements.
Modular construction also requires careful attention to both structural stability and acoustic comfort. Modular buildings are constructed off-site in factory settings, with individual modules then transported to the site for assembly. Acoustic performance in modular buildings can be improved through the use of sound isolation solutions such as the ones available in our Straviwood range.
In summary, both CLT and modular construction offer many benefits, but maintaining structural stability and improving acoustic comfort are critical considerations. Proper design and engineering, along with the use of appropriate materials and construction techniques, can help to ensure that these objectives are met.
