SilentDirect Soft Felt – a moldable felt mat for interior design, acoustics, and automotive customization
SilentDirect Soft Felt is a highly versatile and moldable felt mat, also known as acoustic felt, developed for both soundproofing and interior trim. It is widely used in the automotive industry and is a popular choice for those who want to trim interiors with a durable, aesthetically pleasing, and easy-to-work-with material. The felt works just as well in cars, boats, motorhomes, and RVs as it does in home environments, workshops, and custom-built projects where both function and appearance are important.
Material and technical properties
SilentDirect Soft Felt is made of 100% polyester and has a density of 350 g/m² and a thickness of approximately 4 mm. It is available in white, gray, and black, making it easy to adapt to various types of interiors. This felt mat is manufactured in Europe and offers higher quality than many standard products on the market, which are often thinner and less durable. The combination of density and thickness results in a robust and durable felt that retains its structure over time. The product is sold by the meter or as a full roll of 25 meters (36.25 m²) with a width of 1450 mm, making it flexible for both smaller projects and larger installations.
Extra-flexible and moldable felt mat
The material is designed to be highly pliable and easy to work with. SilentDirect Soft Felt is a stretchable felt mat that can be shaped to fit the substrate and retains its shape after installation. It can be easily cut with scissors or a knife without fraying, making it ideal for both straight lines and more complex shapes. During installation, the felt can be secured using, for example, contact adhesive, spray adhesive, staples, or other fasteners suited to the substrate and application.
Perfect for vehicle interior trim
SilentDirect Soft Felt is particularly valued in the automotive industry thanks to its combination of moldability, durability, and low weight. It is often used for covering panels, walls, floors, cargo areas, and other interior surfaces in cars, boats, motorhomes, and RVs. The material easily conforms to curves and uneven surfaces, making it possible to achieve a professional and uniform result even in complex spaces.
Sound-absorbing properties and improved comfort
As an acoustic felt, SilentDirect Soft Felt helps reduce sound reflections and create a more pleasant acoustic environment. It functions as a complementary layer in acoustic designs and helps reduce echoes and disruptive noise in both small and large spaces. In vehicles, it also contributes to a more muted and comfortable sound environment while driving.
Durable, safe, and easy to maintain
SilentDirect Soft Felt is a durable and hygienic material that is odorless, mold-resistant, and does not release any harmful fibers or emissions. Its smooth surface prevents dust and dirt from sticking as easily, making cleaning and maintenance easier. The felt retains its properties over time and performs well in both dry and more demanding environments.
Why customers choose SilentDirect Soft Felt
SilentDirect Soft Felt is a professional felt mat that combines flexibility, durability, and functionality. It is easy to work with, adaptable to various projects, and provides both a visual and practical enhancement in everything from vehicle interiors to acoustic installations.

Hej Helen,
Tack för ert meddelande,
Den dubbelhäftande tejpen är inget jag rekommenderar.
Du kan sy produkten i symaskin, detta är vad våra skräddare gör på plats i våran tillverknings-verkstad.
Men jag rekommenderar SilentDirect Acoustic Fleece istället då detta är vad vi använder till våra gardiner, en annan notering när man använder ett sådant tjockt material som 4mm Soft Felt är att fallet på gardinen kommer påverkas och inte se lika snyggt ut.
Fördelen med just 4mm skulle vara att den absorberar bättre än de andra tjocklekarna.
Men jag rekommenderar ändå Fleece bakom gardinerna.
En lösning du även kan använda dig av är strykband,
Är du osäker över hur din symaskin ska hantera tjockleken rekommenderar jag faktiskt att du använder dig av stryckband.
Hoppas detta var till hjälp.
Ha en fortsatt bra dag.
MVH

Hej Moa,
Tack för ditt meddelande.
Ja, detta material går att tvätta i 30 graders värme i tvättmaskin.
Nej, tyvärr är det hela meter som gäller.
Men du kan beställa så lite som 1 meter upp till hela rullar på 50meter.
Vi har nuvarande inga mätningar på denna produkten.
Men ur min professionella insikt skulle jag vilja påstå materialet dämpar:
Enkelt lager 3-4 decibel, medan i dubbelt lager 6-7 decibel.
Hoppas detta var till någon hjälp, Ha en fortsatt bra dag.
MVH.
/Elias
