Soniflex door insulation


When thinking about optimizing the acoustics in a given room, ceiling and walls are what comes to mind first and foremost. However, it is often the door with its low mass that constitutes an entry point for noise. For this reason, experts commonly count doors among the so-called sound bridges. We at soniflex are here to help you with door insulation and offer you high-quality options for the effective and visually attractive sound-proofing of doors.


Areas of application for door insulation

Our noise-control solutions are for instance perfect for rehearsal rooms, recording studios or home theaters. But also for doctors' offices, law firms and office spaces - wherever the need for privacy and concentration requires that no sound be transmitted to adjacent rooms and that no outside noises disturb a confidential consultation. Our door insulation system is the ideal solution for effectively minimizing distracting sound transmission wherever privacy and quiet are needed.

soni PORTA
Effective and comfortable door insulation with soni PORTA Earsplittingly loud music from your teenager's room, bothersome noise from the hallway, loud phone conversations from the adjacent office, lack of discretion in treatment rooms - wherever closed doors are supposed to provide undisturbed quiet, our door insulation kit is the ideal solution for effective noise reduction.Our soni PORTA solution consists of six precisely fitting elements that form an attractive pattern and are simply glued to the door using the two included installation aids and our easy-to-understand installation instructions. Thanks to our unique, protected self-adhesive solution, you can remove soni PORTA again from smooth surfaces without leaving any residue, if necessary, for instance when moving out.Elegantly shaped cutouts for the door handle, on the left or right as needed, complete the sophisticated design.Depending on the application, the material has to be mounted either on the inside or on the outside of the door. For this reason, soni PORTA has been designed in two standard heights. It is important to install the door insulation material always on the side of the noise source.Functional explanation: Sound waves spread out from the noise source and hit the nearest surfaces. In order for these waves to be effectively absorbed or dampened, the insulation material must be installed where the waves first hit – i.e. on the side of the door facing the noise source.soni PORTA is suitable for the sound insulation of any room door with rebate - in private homes as well as in day-care centers, kindergartens, schools, medical facilities, offices, hotels, banks, etc.The soni PORTA elements are made of a combination of two highly effective acoustic materials: a heavy layer and an acoustic foam layer. The heavy layer on the underside of soni PORTA is glued directly to the door leaf, increasing its mass and thus the overall sound insulation effect of the door. The visible side consists of an acoustic foam layer covered with an attractive felt material. The foam’s open cells absorb sound energy. The robust and dirt-repellent felt surface is available in trendy colors. The edges of the elements can be masked with our soni VLD adhesive tape, if desired.For ordering the soundproofing set that fits your door, you will need the outer dimensions of the door leaf. Please measure the width and height of your door leaf on the outside, i.e. on the side in the direction in which your door opens.Please note: If the gap between the door leaf and the floor is too wide, we recommend mounting a door sweep or a door bottom seal. Only when all gaps and openings around the door are closed, perfect soundproofing is possible. soni PORTA is also available in a version that is not removable without residue: soni PORTA Basic Important information on installing soni PORTA door insulation: Correct installation is crucial for soni PORTA to be fully effective: 1. unhinge the door before installation and place it in a horizontal position on a stable surface. 2. apply the individual insulation elements horizontally to ensure optimum adhesion of the adhesive. Do not apply when hanging! The weight of the integrated heavy film could cause the adhesive to come loose again (does not apply to soni PORTA Basic). 3. leave the door to rest for at least 24 hours after installation and only hang it up again the next day. This will ensure that the door insulation remains in place permanently and that optimum sound reduction is achieved!

soni COMPOSITE
soni COMPOSITE sound insulation mat – effective sound insulation and sound absorption in one product The soni COMPOSITE sound insulation mat from soniflex is a highly effective combination of sound insulation and sound absorption. This acoustic product consists of a heavy plastic film (soni EVA) and high-quality acoustic foam with a decorative felt surface. This intelligent combination of materials reduces both airborne and structure-borne noise, resulting in a noticeable reduction in noise levels – ideal for use in living spaces, offices, workshops or technical facilities. Double effect – sound absorption & sound insulation While the soni EVA heavy-duty film reliably reduces sound penetration, the open-pored acoustic foam layer absorbs the sound within the room. This dampens the noise at its source and prevents it from spreading – a real advantage over single-layer materials. Typical areas of application: ✔ Partition walls & neighbouring walls in flats and offices ✔ Machine cladding & engine rooms ✔ Workshops & technical rooms ✔ Suspended ceilings & drywall constructions ✔ Music rooms & recording studios Use of soni COMPOSITE – versatile & effective The soni COMPOSITE sound insulation mat is particularly suitable for soundproofing walls and ceilings. Installed, for example, on the wall separating you from your neighbours or behind a facing shell, the material significantly reduces disturbing noises and ensures pleasant room acoustics. Thanks to its decorative felt surface, soni COMPOSITE is available in a range of colours – ideal when function and design are equally important. Easy processing & secure installation Processing soni COMPOSITE is straightforward and does not require any special tools: ✔ The mat can be cut to size precisely using a craft knife or scissors. ✔ The self-adhesive backing serves as an installation aid – however, mechanical fastening (e.g. screws, press studs or strips) is recommended for permanent attachment,     especially on vertical surfaces or for ceiling installation. ✔ Ensure that the substrate is dry, dust-free and smooth to ensure optimum adhesion. If necessary, you can cut soni COMPOSITE to the desired size with a craft knife. The self-adhesive backing serves as an installation aid. Tip: To create a clean finish at the joints, you can cover them with a wooden strip (8–10 cm wide) – this ensures a neat appearance and provides additional support. Safety & quality – tested for professional use soni COMPOSITE materials are age-resistant, moisture-resistant and free of fibres that are harmful to health. This makes this sound insulation mat a durable and safe solution for effective noise protection in both private and commercial areas.

soni EVA
soni EVA is a soft, elastic heavy layer on the basis of EPDM/EVA polymers with an admixture of flame-retardant minerals. Our soni EVA heavy layer is suitable specifically for technical applications, vehicles and machinery. It is designed to eliminate vibrations and drumming of sheet metal and metal parts. Applied to a metal structure, soni EVA will effectively reduce the sound level and prevent the transmission of noise and vibration. For soni EVA, the optional self-adhesive equipment of the rear face serves primarily as an installation aid. In the case of installation on a vertical surface or on a ceiling, we recommend additional mechanical fixation.
