Polyurethane Systems for building and industry

The most demanded solutions to isolate floors acoustically

Noise inside dwellings is very common, but depending on the materials used and the insulation performed, it can be more or less intense. The shuffling of chairs, the crying of a baby, the noise of the washing machine, the conversations ... even the noise of snoring can be transferred from one house to another.

This sound is transmitted when sound waves strike on a surface. Therefore, if we want to avoid that the internal sound of the rooms expands or that the external sound enters inside the house, it is necessary to isolate the surfaces that surround that room.

In order to be able to isolate a house correctly, it is necessary to analyze important points such as the type of noise, the frequency of the noise, the type of structure to be insulated, the materials used ... Fortunately, today we do not have to keep on to bearing the noise of our neighbors as there are different solutions available to isolate the floors from an acoustic point of view.

The most demanded solutions for acoustic insulation of floors

A very common solution to acoustically isolate a home is to place a raised floor over the original one, and between both, to install an insulation material that reduces noise. These types of performances are very effective since they manage to attenuate up to 90% of the noise.

Fiberglass, rock wool, expanded polystyrene, cellular glass, polyurethane foam or phenolic foams are some of the most used materials to acoustically isolate a home.

There are also other solutions that combine two materials by increasing the isolation of sound waves transmitted solidly to the outside, and acting as a barrier against noise towards the interior. We can include in this group the PKB2, the agglomerates or the texfon.

Properties of polyurethane as an acoustic insulation

Polyurethane systems are a good solution to acoustically isolate floors as they meet the levels required in the Basic Noise Protection Document, where the allowed decibels are greatly restricted.

If we speak concretely of its use in houses, their characteristics, such as their high sealing capacity, allow them to be used in all elements of any home: walls, sanitation and windows.

Thanks to their high sealing capacity, the application of polyurethane systems (either in plating, injected or projected) is very effective in absorbing noise and soundproofing the house. In addition, it provides very good results in isolation from airborne noise, so it is used not only in homes, but also in places with higher levels of decibels such as discos, cafes or factories.
