Constructions to enhance quality of life

Vibrations emanating from nearby railway lines or industrial installations generate noise and vibrations. Isolating buildings, or parts of buildings, prevents tremors and the negative side effects those can cause. The vibration isolation products developed by Getzner satisfy all relevant standards at a reasonable cost.

Lesmac provides solutions for:

Elastic mounting of buildings: Understanding and mastering the challenges involved

Elastic mounting systems using Sylomer® are an efficient way to reduce the transmission of vibrations from the surroundings into the structure. Case Studies from Getzner help to understand what successful projects for vibration isolation of buildings look like.

Resilient mounting systems for stairs: Step lively

Walking can cause vibrations and noise which can affect adjacent rooms, transmitted through walls and ceilings. One common source of such problems are stairs.

Fortunately, this is a problem which is easy to solve. By mounting the stair flights and the foundations, it is possible to minimize the transmission of vibrations to other parts of the building. Mounting of this kind can be carried out with full surface, strip or discrete bearings. With Sylomer®, planners have an excellent, proven material available for ensuring elastic isolation, which can be used in a variety of construction designs.

Working with wood: Knocking out the knocks with Getzner products

Even though wood is a beautiful material to build with, it has the disadvantage that it can be excited with a very small amount of energy and transmits noise quite well. As a result, builders working with wood face special challenges when it comes to noise protection. Transmission of noise is also influenced by the type of joints that used between partition walls, side walls, ceilings and structural components, and the type of materials can also be an important factor.

Footstep noise and airborne noise can be transmitted directly through the ceiling, but also indirectly, for example via exterior walls or ventilation shafts. Noise can also be transmitted more easily if there is solid contact between the partition walls. Working together with construction designers from various areas, Getzner has developed new solutions in the field of noise protection. Sylomer® insert pads are an effective means of interrupting the transmission of noise and help to ensure good isolation of the rooms.

Footstep noise: Fleet feet

Depending on their weight and speed, people make noise when they walk. The resulting footstep noise can be transmitted to nearby rooms via walls and ceilings, causing annoyance. The relevant values are set forth in DIN 4109 for multi-story residential dwellings. Designers can help block transmission of footstep noise by isolating components which propagate the vibrations. Isolation of this kind can be carried with full surface, strip or discrete bearings. For new building construction, the use of insulation mats for footstep noise on a floating base has become the most common method, and the special solutions developed by Getzner are frequently used for renovation projects.

High-Resilient Bearing

The high-resilient bearings isolate vibrations and concussions in structures extremely efficiently, even while taking up minimal space (loads up to 6 [N/mm2]).

Many buildings, such as high-rises, must be supported on elastic bearings in order to efficiently protect them from vibrations and concussions. High-resilient elastic bearings are also required for structures in which high loads meet very small areas, such as for crane installations, steel structures and heavy machinery. However, high loads typically also require large bearing surfaces over which the weight can be evenly distributed. In many cases, such large surfaces are not available due to design constraints.

The high-resilient bearings from Getzner offer high performance, particularly with small support surfaces.
