■ SOLUTIONS FOR ACOUSTIC INSULATION TIMBER STRUCTURES

ACOUSTIC INSULATION FOR TIMBER STRUCTURES Acoustic in wooden buildings depends on a careful study and an accurate project execution For more than 40 years, Isolgomma has been developing products and solutions for acoustic and thermal-acoustic insulation geared towards improving the quality of life. Ever since its foundation in 1972, the launch of innovative products, covered by international patents, the expansion towards new markets and sectors and the achievement of quality certifications have made Isolgomma a well-known and appreciated brand all over the world, result of high experience and...

Acoustics and comfort within wooden buildings Wooden buildings are more and more considered as a valid alternative to the traditional constructions in reinforced concrete. Wooden buildings are very common in Northern European countries and are spreading massively both in Italy and in the rest of Europe. The reasons for this continuous growth lie in the unique properties of wood, such as excellent thermal insulation and mechanical resistance. The main advantages of timber structures are: ■ Anti-seismic behaviour: thanks to a light weight and to the types of connections, wooden walls are less subject...

ACOUSTIC INSULATION FOR TIMBER STRUCTURES Timber joists floors Timber joists floors are very common and are still used a lot in new constructions, also due to their low weight and excellent structural behaviour. In old buildings, this type of floor is very common and it is often preserved during renovation projects, both for its functionality and for aesthetic purposes, which is appreciated in all the markets. To grant the compliance of the old wooden floors with the most recent technical standards and regulations, very often during renovation a structural reinforcement and stiffening is adopted...

CLT Floors and walls The CLT technology was born and developed as an innovative and an alternative to the wooden frame structures. The concept of CLT is based on prefabricated wooden panels which, disposed both horizontally and vertically, will form the bearing structure of the building. The CLT panels can be produced with a wide variety of dimensions, up to 5 meters per 20 meters long, with a thickness that can exceed 40 centimetres. The prefabricated panels are to be installed on site, through standard mechanical fixing elements. A subsequent advantage of this technology is that the CLT elements...

Acoustic and thermal insulation for floating floors HIGHMAT products have been developed to reach extremely high insulation on floors with the floating screed technology. Highmat is a combination of rubber bearings and polyester fibre assembled together in stand-alone panels, to be positioned on the base floor before casting the floating screed. The Highmat system is the ideal choice to reach a first-class acoustic performance on all floor typologies. This product is particularly indicated for wooden floors as it increases significantly the acoustic performance at low frequencies and allows to...

Acoustic and thermal insulation for floating floors APPLICATION FIELDS UPGREI is a product line for high performance in acoustic insulation, developed with cutting-edge technologies, for applications in the construction using floating screeds. Upgrei is made in rolls using a special type of EPDM rubber that exploits the tried and tested Grei technology, coupled with a polyester fibre layer. The combination of these two materials gives the product excellent acoustic, thermal and mechanical properties. The Upgrei line is ideal for impact sound insulation of wooden floors, especially when high acoustic performances...
