Compact Design – No Added Ceiling Height

Both hanger types are engineered as extremely simple sheet‑metal components that can be installed directly with wood screws. To support tight construction height requirements, the hangers are optimized so they do not increase the total ceiling height—the ceiling grid can be installed flush with the I‑joist or CLT element.

We currently offer two ceiling grid options:

• GK60 mm
• Wooden bar

AH60W – For GK60 mm Ceiling Profiles (Up to 25 kg Load)

The AH60W acoustic hanger uses a 3 mm InfiniSpring® element and is tailored for the GK60 mm metal ceiling profile.

• Designed for 25 kg maximum load, matching our existing GK60 hangers
• Optimal load range 15–25 kg to meet typical support distance requirements
• Height‑minimized with an upper spacer to prevent spring contact with the I‑joist/CLT
• Installed using standard wood screws

A sample table of recommended support distances is provided below.

P = Support distance along the I‑joist or CLT element
T = Support distance between adjacent I‑joists or CLT elements

The following performance curve provide the natural frequency of AH60W hanger relative to applied load, supporting accurate acoustic design.

AHWW – For Wooden Bar Ceiling Grids (Up to 45 kg Load)

For wooden grid structures, the AHWW acoustic hanger uses a 4 mm InfiniSpring®-spring, providing increased load capacity and longer support distances.

• Designed for loads up to 45 kg
• Equipped with spacers on both upper and lower connections to ensure the spring does not touch the I‑joist/CLT or wooden bar
• Allows significantly greater support distances compared to thin GK60 steel profiles
• Can reduce the total number of hangers needed for the suspended ceiling

Customer Feedback

We are pleased to share positive feedback from Jarno Valkama of Rakennustoimisto Pekka Kynnös Oy: “The installation of InfiniSpring acoustic products went smoothly, and we are happy to continue using these products in the future.”

Acoustic Performance Validation

To confirm compliance with the National Building Code of Finland’s noise requirements, comprehensive acoustic measurements were carried out at Pehula. InfiniSpring solutions are designed to minimize both impact noise and airborne noise, creating a better learning and working environment. Special attention was given to sensitive areas such as the music room, where sound isolation is critical to prevent disturbance in adjacent spaces.

The results clearly meet the required standards. Below is a summary of the measurements:

Standardized Sound Level Difference (DnT,w)

Measurements were performed using a loudspeaker connected to a pink noise generator. Sound pressure levels were recorded in both transmitting and receiving rooms, and standardized sound level differences (DnT) were calculated based on reverberation times. Both results horizontal for the wall structure and vertical for the floor exceed the requirements.

Figures 1 and 2 show the structural setups and measurement results.

Figure 1. Standardized sound level No 1 DnT,w 55 dB

Figure 2. Standardized sound level No 2 DnT,w 73 dB

Standardized Impact Sound Level (L’nT,w)

Impact sound measurements were conducted using a standardized impact sound device. Sound pressure levels were measured in the receiving rooms, and L’nT,w values were determined using the reference curve procedure.

Again, both results clearly meet the requirements. Figures 3 and 4 show the detailed measurement data.

Figure 3. Standardized impact sound level No 1 L’nT,w 45 dB

Figure 4. Standardized impact sound level No 2 L’nT,w 27 dB

Conclusion

The Pehula project demonstrates how InfiniSpring acoustic solutions deliver reliable performance, ensuring compliance with strict noise regulations while enhancing comfort in educational environments.

Transforming Pipe Support Design for Quieter Spaces

One of the latest innovations using InfiniSpring® technology is the Acoustic Pipe Support, which redefines how pipes are mounted and isolated. Traditional supports, such as those based on SFS 5377, create rigid connections that transmit noise and vibration into surrounding structures.

By replacing the stiff vertical U-profiles (U50) in these supports with InfiniSpring® springs, the system becomes flexible and acoustically optimized—dramatically reducing sound transmission. This makes InfiniSpring® Acoustic Pipe Supports an ideal choice for environments where acoustic performance is critical.

Real-World Application: Hospital Installation

The first InfiniSpring® Acoustic Pipe Supports were installed in a hospital setting for a horizontal DN300 pipe, using two key components:

• InfiniSpring® Acoustic Pipe Slide
• InfiniSpring® Acoustic Anchor Point

These components work together to manage thermal expansion and vibration. The Pipe Slide allows the pipe to move freely within a groove, while the Anchor Point absorbs high longitudinal loads while remaining flexible in other directions. This combination ensures both structural integrity and acoustic isolation.

Custom Solutions for Healthcare and Beyond

InfiniSpring® Pipe Supports are fully customizable for different pipe sizes and applications. Whether you’re designing HVAC systems, medical gas lines, or industrial piping in sensitive environments, we can help create a solution that meets your acoustic and structural needs.

InfiniSpring® has developed a novel prototype of a vibrating conveyor. Students at SeAMK have followed vibrating conveyor development and supported with the manufacturing drawings and assembly of the vibrating conveyor. Vibrating conveyor was first assembled and tested at SeAMK laboratory to validate design simulations. A Finite Element (FE) simulation model of the vibrating conveyor enables in-depth analysis of the converyor’s mechanical and dynamic behavior, allowing students to see simulated data being compared to prototype testing data. In the future SeAMK students can use vibrating conveyor for studying real life dynamic and vibration phenomena. Students can also practice vibration measurements using the vibrating conveyor.

Vibrating conveyor prototype is incorporating InfiniSpring®-springs in a clever and efficient way. The conveyor is constructed entirely from sheet metal steel, manufactured exclusively using laser cutting. It is powered by an eccentric motor with adjustable speed, and the system allows for changes in both motor RPM and spring angle.

This prototype demonstrates impressive functionality:
At 5300 RPM and a 45-degree spring angle, the conveyor operates with smooth, consistent vibratory motion and effectively conveys materials in a continuous flow. The use of InfiniSpring®-springs enables not only vibration but also contributes to the efficient, integrated design of the entire structure.
InfiniSpring Company will productize vibrating conveyor designs. Ultimately, the goal is to design an optimized and simplified version where the InfiniSpring®-springs become an integral part of the conveyor’s structural frame. We look forward to showcasing the final vibrating conveyor designs later once they are complete.

If you’re interested in integrating InfiniSpring®-springs into your vibratory machinery or dynamic systems, don’t hesitate to contact us. We’re always open to new collaborations and applications.
