Sealing strip for windows & doors – SilentDirect Seal 20 meters

SilentDirect Seal – sealing strip for effective soundproofing and vibration damping

SilentDirect Seal is a high-performance sealing strip made of nitrile rubber (NBR), specially developed to stop sound leakage, dampen vibrations, and create a quieter, tighter, and more energy-efficient environment. The sealing strip is delivered in a roll and is 20 meters long, making it easy to cut and adapt as needed. It comes in several widths – 8mm, 15mm, 25mm, and 50mm – and thicknesses of 2mm, 3mm, 4mm, and 6mm to suit various constructions and applications. With its self-adhesive backing and high durability, SilentDirect Seal is the obvious choice for soundproofing doors, windows, hatches, and technical installations in both private and professional settings. Whether you're building a soundproof wall, sealing a boat hatch, improving a door frame, or reducing vibrations in an engine hood, SilentDirect Seal offers a versatile solution with proven high performance.

Superior soundproofing and vibration control

SilentDirect Seal is often used to prevent sound transmission in sensitive junctions, such as between framing and walls, ceilings, or floors in new builds or renovation projects. By absorbing vibrations and structure-borne noise at these contact points, it helps create quiet rooms with professional-grade soundproofing. The sealing strip is also particularly effective around doors and windows, where it blocks sound leakage and drafts that can easily enter through cracks and gaps. The result is a quieter, more private, and comfortable indoor environment – whether it’s a bedroom, office, or conference room.

Easy installation with self-adhesive backing

SilentDirect Seal comes with a powerful self-adhesive backing for quick and easy installation. Simply peel off the protective film and press the strip onto the desired surface – no tools or special skills are required. The double-sided tape is also eco-friendly and designed for long-lasting adhesion, even in damp or exposed environments. Thanks to its ease of installation, SilentDirect Seal is a practical option for both professionals and DIY enthusiasts looking to achieve high-quality soundproofing with minimal effort.

High durability in demanding environments

SilentDirect Seal is engineered to perform under extreme conditions. The sealing strip withstands temperatures from -50 °C to +110 °C, making it ideal for everything from cold storage rooms to hot engine compartments and machine halls. The material itself is naturally flame-retardant, offering added safety in areas where fire resistance is critical. The product is also water- and moisture-resistant, making it an excellent choice for marine installations, boat environments, and other exposed outdoor conditions.

Wide range of applications – from doors and windows to industrial use

Thanks to its combination of sound damping, vibration control, and sealing properties, SilentDirect Seal is suitable for a wide variety of environments. In homes, it is an excellent choice around exterior doors, interior doors, and windows, where it improves soundproofing and blocks drafts. By sealing these areas, you create a quieter and more energy-efficient living space with increased comfort and reduced energy consumption. In vehicles, the strip works perfectly as sound insulation for doors, engine hoods, and trunk lids. In marine environments, it enhances tightness and reduces noise in boat hatches, vents, and engine compartments.

In technical installations such as cabinet doors and ventilation hatches, SilentDirect Seal reduces both noise levels and vibrations, creating a more pleasant operating environment. In construction projects, it is especially useful as a vibration-damping strip between wooden or steel studs and adjacent surfaces to break sound bridges and prevent the transfer of disruptive structure-borne noise. In industrial applications, SilentDirect Seal functions as a sealing and vibration-damping component between machine parts or between machinery and the floor – particularly valuable in environments where noise reduction is essential for the work environment.
