From Embedded to Replaceable: Jack-Up Floor Systems for Every Acoustic Challenge
Entity view (Content)
What is a Jack-Up Floating Floor System?
Jack-up floating floors are high-performance vibration and noise isolation systems with very low risk for acoustical bridges. Unlike other floating floor types, jack-up systems lift the slab after it’s poured, guaranteeing a clean separation and consistent performance.
This method guarantees a high level of performance and reliability, especially in demanding applications such as auditoriums, gymnasiums, theatres, and sports halls.
Main Benefits of Jack-Up Systems
Jack-up systems provide a unique combination of structural and acoustic advantages, making them a go-to solution for critical projects:
- Reduced Risk of Acoustic Bridging: The slab is raised post-pour, eliminating contact points and reducing risk of flanking paths.
- No Formwork Needed: Streamlines construction and saves installation time.
- Slim Build-Up Possibilities: System height isn’t limited by isolator thickness.
- Customizable Air Void: Tailor acoustical performance to each project’s needs, without redesigning the whole system
- Use Pre-Lifted Slab for Storage: Efficient use of space during construction.
- Adapts to Complex Layouts: Easily accommodates irregular room geometries.
