Bullet proof vest technology
Buildings tend to move a little bit as gravity and pressure does its work.Sometimes temperature variations and variations in humidity adds up to this as well. The solution to this is normally called expansion joint.
An expansion joint however is nothing you’d like to have in your design because of its fabulous look – on the contrary it’s often quite ugly.
The expansion joints needed to take care of the movements in the construction of the building are difficult to do anything about, but the expansion joints needed to take care of the internal stress in for example ceilings and walls are something completely different. They can be eliminated by the selection of which type of material to use.
Let’s use seamless acoustical ceilings as an example. Convenient as we happen to know quite a lot about them.
Most types of seamless acoustical ceilings have limitations due to the internal stress in the material. Normally these limitations are set to 150 – 200 m2 single sheet without having to start over with an expansion joint in between.
Fellert acoustical ceilings however, can be installed in single sheets 1000 m2 in size (sometimes even larger) without any need of expansion joints.
This is because of the extreme flexibility of the Fellert plaster, where the cotton fibers used in the plaster will act as reinforcement taking up a the shifitings and movements internally. We call it Bullet proof vest technology.
