Sound and heat insulation

An upgrade for your floor: Our impact sound insulation mat for more comfort and quiet.

What supports sound insulation?

Impact noise is the sound generated by footsteps or other movements on the floor and which spreads through the floor and adjacent walls and ceilings. Uncontrolled impact noise transmission can cause sounds and vibrations to spread undesirably throughout the room, leading to significant nuisance. Appropriate impact noise insulation can help reduce the spread of impact noise, thereby improving room acoustics and quality of life. There are various types of impact noise insulation that can be used depending on the application and floor covering.

A common method for impact sound insulation is the use of special insulation mats that are laid under the floor covering. These mats are made of different materials and have different thicknesses to dampen the sound according to requirements. It is important to select the appropriate impact sound insulation according to the requirements and the intended area of application. For example, a high-traffic area such as a hallway or stairwell requires stronger impact sound insulation than a bedroom or living room. By choosing the right impact sound insulation, not only can sound transmission be reduced, but also a pleasant feeling underfoot and improved thermal insulation can be achieved.

DURAL Impact Sound Insulation Mat SW14

The DURAL impact sound insulation mat SW14 was specially developed to reduce impact noise in rooms with ceramic floor coverings. With a thickness of only 1.3 mm, it is extremely thin and therefore does not affect the height of the floor structure. Besides improving room acoustics, the mat also offers reduced cold feet without impairing the effect of underfloor heating. The mat consists of four layers and forms the perfect base for laying under ceramic floor coverings in residential, commercial and industrial areas. It is suitable for substrates such as wood, concrete, screed (including heating screeds) and similar. It can also be laid on existing, old coverings or under additional radiant heating systems.

With the impact sound insulation mat, you get a first-class mat that not only reduces impact noise and improves room acoustics, but also provides a pleasant feeling underfoot. Furthermore, it offers easy and quick installation on various substrates and is therefore suitable for many applications.

Properties of the DURAL impact sound insulation mat SW14

The combination of light and soft layers with heavy and hard layers is the basis for the diverse properties of DURABASE SW14.

1. Soundproofed to the substrate
2. Impact noise reduction of up to -14dB
3. Improving room acoustics
4. Good thermal conductivity, ideal for underfloor heating
5. Diffusion-open
6. Stress-relieving and pressure-stable
7. Only 1.3 mm thin
8. Free of PVC and halogens
9. Difficult to ignite / Not easily flammable

The properties for impact sound insulation are certified with a test certificate from the Material Research and Testing Institute Leipzig/Germany.

Areas of application for the DURAL impact sound insulation mat SW14

Our impact sound insulation mat is extremely versatile and can be used in various applications, including private rooms, commercial spaces, and offices. It is capable of supporting surface loads of up to 2.0 kN/m² under tiles. The sound insulation mat can be installed in conjunction with ceramic tiles or natural stone tiles on standard underfloor heating systems, as it is suitable in terms of thermal transmittance resistance. Surface supplementary heating systems can also be applied to the SW mat according to the manufacturer's instructions.

The mat is suitable for installation on a variety of substrates such as cement screed, heating screed, anhydrite screed with a residual moisture content of less than 3%, wood, chipboard, tiles or similar. Another practical application is that it can also be installed over existing floor coverings. This saves the need to install a new screed with better insulation.

Processing

1. The substrate must be dry, free of adhesion-inhibiting components, load-bearing and even. Any leveling measures must be carried out before laying our sound insulation mat.
2. Prepare the properly prepared substrate with a suitable primer.
3. Apply thin-bed or flexible adhesive mortar to the substrate with a 4 x 4 mm notched trowel. The choice of adhesive depends on the type of substrate. For most substrates, a hydraulically setting flexible adhesive mortar or a fast-setting flexible adhesive according to DIN EN 12004 / C2 can be used.
4. Place the cut-to-size strip with the print facing upwards onto the adhesive and press firmly. Lay the strips end-to-end. Offset the joints of adjacent strips by at least 30 cm at the end of the strip.
5. Cut edge insulation strips approx. 5 cm high and place them around the walls. If necessary, additionally cover all mat joints and edge connections with a self-adhesive covering tape (approx. 2 cm wide).
6. After the tile adhesive has cured sufficiently, the tiles or natural stone coverings can be laid directly onto the mat using the thin-bed method. Generally, the generally accepted rules of technology must be observed! For all products/materials: The suitability for mechanical and chemical stress must be carefully checked in each individual case before laying the mat. Protect material from sunlight.
