Acoustic Sealant

Ultrakustik VS is a neutral vibration isolation silicone sealant.

High level of sealing

Ultrakutik VS acoustic sealant completely fills seams and joints, providing a high level of vibration isolation.

It does not tend to crack, crumble, reliably seals seams of any size and depth.

It is resistant to moisture, temperature changes, and solar radiation.

Stable elasticity

Ultrakustik VS retains elasticity and firmness after drying and under load. Over time, it does not crack and does not peel off, while continuing to effectively prevent sound from entering the isolated premises.

Excellent Adhesion

Ultrakustik VS has excellent adhesion to a wide range of surfaces and materials.

Easy to apply on horizontal, vertical and inclined surfaces.

Ultra Effect in Combination with Ultrakustik Tape

To achieve maximum protection against propagation of structural vibrations through structural elements, it is recommended to use Ultrakustik VS together with Ultrakustik Tape.

By eliminating rigid connections and sealing joints with the use of Ultrakustik VS and Ultrakustik Tape, sound insulation increases by 5 dB!

Features

The sealant is easy to use. Its consumption is controlled using a special conical nozzle.

Ultrakustik VS is not aggressive to metal and other materials, has good adhesion, and dries quickly. It is resistant to moisture, sunlight, and temperature changes.

After hardening, the sealant has no smell and is completely safe to use.


Maintenance info

Composition and description

Made from silicone resins and silicon-containing modifying additives.

Storage

Ultrakustik VS sealant tubes should be stored in dry enclosed spaces away from any precipitation and groundwater at temperatures from +5 to +25°C (41°F - 77°F).

The sealant may be stored in closed cardboard boxes stacked no higher than 2 m (6.6 ft.).

Features of the material usage

Ultrakustik VS acoustic sealant is used to fill joints in the structures of soundproof floating floors, ZIPS panel system, frame soundproofing partitions, claddings, and suspended ceilings.

All activities should take place in ventilated areas. Avoid getting uncured sealant in the eyes or on the skin. In case of contact with mucous membrane or the eyes, rinse immediately with plenty of water.

Aleksandar 27 January 2023
What is the difference between this sealant and any other sealant available on the market?
Expert answer

Vibration isolation is one of the most important aspects in building a soundproof structure. Ultrakustik VS remains elastic and does not harden.

Slobodan 27 January 2023
What is the sealant consumption?
Expert answer

As a rule, the consumption is as follows: 1 tube per 4-5 meters (13-16 ft.) of seam.

Ana 27 January 2023
Is it possible to replace Ultrakustik VS with conventional silicone sealants?
Expert answer

No. Ultrakustik VS sealant has a special composition for better adhesion to soundproof structure materials. Also, conventional silicone sealant has high dynamic stiffness values, which negatively affects its damping properties.
