soni 491 STL – Sound insulation board with heavy foil for effective wall and ceiling insulation Combined sound insulation and sound absorption in one product Our soni 491 STL sound insulation board is a highly effective PUR foam-based sound insulation product that is additionally combined with a heavy bitumen foil. The acoustic foam with sound-permeable foil ensures optimum sound absorption, while the bitumen layer effectively insulates and blocks sound. This intelligent combination of materials combines both sound insulation and sound absorption properties in a single product – ideal for anyone who wants to effectively reduce noise and create a quieter environment. Areas of application – versatile, efficient and reliable soni 491 STL is used wherever noise and sound transmission needs to be reduced – for example: ✔ Wall insulation between neighbouring flats ✔ Partition walls or ceilings in apartment buildings ✔ Technical rooms, machine rooms or workshops ✔ Cellars, garages and house walls The sound insulation board is ideal for retrofitting existing walls or ceilings with sound insulation – for example, by constructing a facing shell or cladding partition walls. Tip for constructing a facing shell: A facing shell is a very effective way of significantly improving wall insulation between neighbouring properties. Here's how to do it: 1. Attach battens: Attach 30 mm or 50 mm thick wooden battens to the wall. Use our soni NBR sealing tape to insert an elastic layer between the wall and the battens. This prevents sound bridges. 2. Insert sound insulation boards: Fill the gaps with soni 491 STL to achieve both sound insulation and sound absorption. 3. Attach cladding: Screw plasterboard or chipboard onto the battens. 4. Decoupling & joint sealing: Separate the construction from the floor, ceiling and adjacent walls with a small gap and seal the joints with acrylate for maximum insulation performance. Tip: In our experience report ‘Neighbourhood / facing shell’, you will find a practical example of how soni 491 STL can significantly improve the sound insulation of a wall. Alternative with visible surface: soni COMPOSITE If plasterboard cladding is too costly for you, we recommend our soni COMPOSITE as an alternative. This material combines sound insulation and sound absorption like soni 491 STL, but has a decorative felt surface in various colours – perfect for visible areas. Advantages of soni 491 STL at a glance ✔ Combined sound and heat insulation ✔ Heavy bitumen foil for high sound insulation ✔ PUR foam for strong sound absorption ✔ Wipeable, micro-perforated surface ✔ Self-adhesive and easy to process ✔ Effective noise reduction between neighbouring flats ✔ Ideal for facing shells, wall insulation, ceiling cladding ✔ Easy installation with a cutter knife and adhesive surface

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!
