Membrane Ceiling
Safe and comfortable. Rich in design and environmentally friendly, this is the ceiling of the future.
Ceilings are not only at risk of falling during major earthquakes. Ceilings falling due to aging and deteriorating base materials, daily delicate vibrations, wind and thermal contraction, and other such causes have been reported all over the world today.
Replacing heavy and hard conventional ceilings, a new concept of soft, lightweight, and strong membrane ceilings gently wrap people’s lives.

What is a Membrane Ceiling?
This ceiling construction method creates safe and comfortable spaces.
The danger of falling ceilings is not limited to major earthquakes. Aging and deterioration of the base material, daily delicate vibrations, cold and heat shrinkage. Ceiling falls due to these causes have been reported all over the world today.
Replacing heavy and hard conventional ceilings, a new concept of soft, lightweight, and strong membrane ceilings gently wrap people’s lives.
Feature
Light
Less damage in case of a fall
The mass of the membrane material is approximately 600 g/m². Compared to conventional ceiling materials, it is very lightweight, minimizing damage to people and objects in the room in the event of an unexpected fall.
Soft
Resistant to deformation and collision, and resistant to swaying and falling
The thin and soft membrane material not only enhances the room’s design, but also makes the structure capable of following deformation even in the event of large seismic shaking, thus reducing the risk of ceiling fallout to an extremely low level.
Strong
Catching Falling Objects
In spite of its extremely thin material with a thickness of only 1 mm, it has been proven in in-house tests to be strong enough to catch falling objects.
Drop Impact Testing of Membrane Ceilings - Membrane for Ceilings (BATYLINE)
Bright
Space with high quality light environment
It creates a space with a high-quality light environment by reflecting natural lighting from windows or indirect lighting effects from light transmitted through the membrane material.
Example of indirect lighting effect
Kansai International Airport Passenger Terminal Building
Chiba International Swimming Center
Sound absorption performance
Control room reverberation
Acoustic Measurement Tests
Membrane material: BATYLINE Aw
Facility name: Kurashiki City Indoor Swimming Center (indoor pool)
Room volume: approx. 9,000m² (25m x 36m x 10m)
| Date of measurement | Temperature | level of humidity | |
|---|---|---|---|
| Before installation of membrane ceiling wood, hair and magnesium plate (t=25) |
2012/3/27 | 31°C | 50%. |
| After installation of membrane ceiling BATYLINE Aw (t=0.7) |
2012/7/10 | 32°C | 74%. |

Before installation of membrane ceiling
After installation of membrane ceiling
Comparison of reverberation time before and after installation of membrane ceiling (average value per frequency)
After the membrane ceiling was installed, we confirmed that the reverberation time was reduced, mainly in the 160-200 Hz band.
Air conditioning efficiency
Control airflow to increase air conditioning effectiveness
We cooperated with the Kawaguchi Laboratory of the University of Tokyo’s Institute of Industrial Science in thermal environment measurement experiments, and confirmed that installing a membrane ceiling can control airflow in a room and save energy.
Experimental measurement of humidity-thermal environment of retractable membrane ceilings
When the membrane ceiling is closed
When the membrane ceiling is fully opened
Objective
- Verify the effectiveness of the membrane ceiling in blocking airflow by comparing the vertical temperature distribution in both the upper and lower spaces of the membrane ceiling when the membrane ceiling is closed and when it is fully open during the heating operation period in the winter.
- To verify the energy saving effect of the membrane ceiling by considering the change in heating load due to the opening and closing of the membrane ceiling.

Actual measurement result by thermo camera
By contrast of closing and fully opening the membrane ceiling, the membrane ceiling showed a blocking effect of about 4°C to 6°C when the heating was set at 22°C. (Kawaguchi Laboratory, Institute of Industrial Science, The University of Tokyo)
