Shop / Isotop Sandwich Elements
Sandwich elements are innovative vibration isolators characterised by their high stability and low weight. They typically consist of a pressure distribution plate and an isolating layer. The pressure distribution plates in sandwich elements are mainly produced from strong materials like aluminium, steel or fibre composites (e.g. glass fibre or carbon fibre) to distribute the load evenly. The isolating layer is often made from lightweight materials such as polyurethane foam. The pressure distribution plate allows the sandwich elements to be used with various frame sizes. All that needs to be considered is the weight exerted on the respective bearing point.
Even though they are very light, sandwich elements offer structural strength paired with excellent isolation properties. This is achieved by a unique combination of rigid pressure distribution plates and lightweight isolating layers. Sandwich elements are ideal for applications in which weight-saving and high load capacities are demanded.
The PU foams used as the isolating layer account for the outstanding acoustic isolating properties of the sandwich elements. They are therefore ideally suited for applications in buildings in which sound control is important.
Sandwich elements are easy to handle and install owing to their light weight and construction method, which considerably reduces installation time and costs. Generally speaking, sandwich elements are also low maintenance, resulting in a further reduction in operating costs.
