GM-FF is made using compressible elastomer technology. Compressible elastomers are a completely different technology than vulcanised rubber. Typically vulcanised natural rubber or neoprene is defined as incompressible. This means it requires high loadings in order to obtain some static deflection to provide for any vibration isolation. These types of systems simply do not work in buildings where high floor loading is neither available or desirable. In a similar manner, fibreglass isolators are comprised of rigid particles which loose elasticity when compressed. The end result of this material is a dramatic degradation of performance over time.
Compressible elastomer technology allows for low natural frequency at low loads. Due to the suitability of low loading, the rubber can cover the entire floor surface, providing consistent performance throughout. Vulcanised rubber isolator systems require the isolators to be carefully positioned and extra isolators are often needed depending on weight and position of equipment. This requires additional layout planning, installation and costs.
GM-FF is supplied with a moisture barrier. There is no need for any plywood formwork the material is simply rolled out, with joints taped. The concrete can be poured directly onto it. The only additional accessory required is an edge perimeter flanking isolation strip.
