10 Tips for optimal sound protection

Install soundproof doors

It has been proven several times that permanent noise can make you ill. So this is a point not to be underestimated, which builders should already pay attention to when planning a new house.

Because once the house is up, not much can be aligned without a lot of effort. In the following guide, you will therefore find tips worth knowing about optimal sound insulation in and around the house.

1. Sound insulation already starts with the walls

Who attaches importance to a good sound insulation, should already pay attention with the walls to a sufficient sound insulation. Here it is recommended to use thick, solid concrete walls. Alternatively, you can also go for solid bricks or sand-lime bricks. Even a massive noise barrier with a thickness of 17.5 centimeters can achieve a sound insulation level of up to 58 dB.

2. Optimal sound insulation through special soundproof windows

A very important factor in terms of sound insulation are also the windows. New windows are now often fitted with sound insulation as standard.

But it is not only the glazing that matters, the window fittings and seals should also be of high quality and well adjusted or. Be firmly pressed to the window frame.

Only if these are also really tight do they have good insulating properties of up to 32 dB. However, there are also special soundproof windows that promise even greater sound insulation.

Sound insulation with double glass - this is how it works

In these, for example, special glazing is used which, in contrast to conventional soundproof windows, is asymmetrically constructed and thus breaks the sound waves even better.

If the window glass is also covered with an acoustic film or if the distance between the two panes is increased, the sound insulation effect is even higher. You can find more information about windows with these special sound insulation properties, including competent advice, here.

Builders should make sure that the intended windows have the RAL quality mark. The following video explains compactly what is behind it and what it brings you as a consumer.

3. Simply block out the noise

Sound insulation also continues with the doors. The rule of thumb here is: the heavier, the higher the sound-insulating effect. But the door panel and material also play a significant role – after all, a door is opened and closed countless times a day.

Therefore it should have a high stability. With a modern front door made of plastic, you already get good heat and sound insulating properties, but aluminum front doors are even better, because they are even more stable – you can get front doors with both frame materials at hilzinger.

Also keep an eye on the thickness of the filling, as its thickness also has an influence on the insulating effect. Finally, it is important for you as a builder to make sure that the doors close tightly to the floor so that no sound can penetrate through here.

4. All good things come from above

Especially in regions with a lot of air traffic, noise pollution can be very high. The roof should therefore be planned as a solid construction right from the start and have very good, sound-absorbing insulation.

5. Insulating attics and ceilings

The attic should also be well insulated, as should the ceilings. It is best to use a particularly heavy and also multi-layered construction method here. A floating screed or elastic floor coverings (z.B. Plastic and cork flooring) take a lot out of the sound waves.

6. Roller shutter box

Even if your windows appear to be sound-insulating: if the roller shutter boxes do not also have appropriate insulation, it is not possible to guarantee complete sound insulation. So do not forget about them in your planning!

7. Pipes are an ideal noise carrier

Noise also finds its way into the house via pipes and ducts. The installed pipes should therefore have a sheathing. Sound insulation is optimized by special insulating materials made of tear-resistant multi-composite material.

8. Create a noise barrier with furniture

If noise is transmitted through the walls, it helps to put up large pieces of furniture. This can be, for example, a closet that is placed in front of the wall. It should not be screwed to the wall, however, as the sound waves will otherwise be transmitted to the furniture.

9. Getting to grips with noise with textiles

Textiles are also a good noise killer. High-pile carpets and floor-length drapes with folds can be used to achieve very effective sound insulation. Textile murals are also advisable.

10. Break the sound with multidimensional surfaces

The larger and smoother a surface is, the better sound is reflected. Especially in large rooms, the walls should therefore not be free-standing if possible. If furniture is placed all over the room, such as shelves, room dividers, wall units, desks or chairs, the sound waves can be refracted much better.
