KRONOTHERM Sound

Compression resistance combined with elasticity are the crucial properties of a highly effective acoustically insulating board for laying under hardwood and laminate flooring. Thanks to a newly developed production technology, KRONOTHERM sound ideally meets these requirements. KRONOTHERM sound consists of natural wood fibres which are three-dimensionally interlinked with environmentally friendly binding fibres in an ecologically sound process.
Especially when laid beneath hardwood and laminate flooring, KRONOTHERM shifts the high, bright sound frequencies typical of light foams to lower frequencies that are more agreeable to the human ear. This greatly enhances the sense of wellbeing in a room.

The resonance peak is shifted downward from about 800 Hz to about 320 Hz, or by about four thirds (more than an octave), in a more pleasant frequency range. Studies have also shown that the intensity of high frequencies in particular is significantly reduced by between 15 and 18 dB.

These properties were demonstrated by comparative test series conducted by an independent testing lab (a condensed report is available on request; ask for PB III/S-05-153-6).
KRONOTHERM sound also substantially improves impact sound insulation, thus greatly reducing noise propagation to floors below and improving living quality. KRONOTHERM sound 5 mm thick attenuates footfall sound by Δ Lw = 21 dB. Corresponding studies were carried out in accordance with ISO 140-8.

The improvement in sound levels achieved with KRONOTHERM sound is assessed as follows:

+ 0.5 dB(A) – Improvement only perceptible under good acoustic conditions
+ 1.0 dB(A) – The threshold at which the improvement becomes noticeable
+ 3.0 dB(A) – Signal energy reduced by half
+ 6.0 dB(A) – Sound level reduced by half
+ 10.0 dB(A) – Subjective volume reduced by half

Owing to its stability and resistance to compression, KRONOTHERM sound is ideally suited for glueless laying systems. The most rigorous method for testing joints in these laying systems and underlying layers is the chair roller test. In close cooperation with Kronotex Fussboden GmbH & Co. KG, the world’s leading maker of laminate flooring, we conducted long test series that clearly demonstrated the excellence performance of KRONOTHERM sound. This product’s properties make it superior to nearly all other commercially available subfloor materials.

KRONOTHERM sound is very easy to use and install, does not give off any dust or loose fibres, and is suitable for use over hydronic radiant floor heating systems.

KRONOTHERM sound excels with long-term dimensional stability and can compensate for unevenness of the floor or soiling up to 3 mm thick without creating sound bridges that could otherwise permanently interfere with its noise-attenuating properties.

KRONOTHERM sound is also very pleasant to the touch and skin-friendly. Its skin compatibility has been demonstrated by a study.

Wall bases/clips

In contrast to conventional gluing systems, this floor of the second Clic Generation can be walked on right away because there is no need to wait for the glue to dry.

Simply remove the spacers and cover the remaining separation joints. Wall bases with matching décor are available from your KRONOTEX dealer.

Attach wall base to the wall using expansion plugs or screws. Never attach wall base to the panels, as this would prevent them from moving freely.

"Sound Design" - the silent step guarantee.

Except for Basic Clic and Smart Clic, all the above laminate floorings are available with a fifth layer, "Sound Design" (footfall sound reduction). "Sound Design" makes a sensible choice into a sensual pleasure. It reduces the footstep impact, decreases noise generation and increases walking comfort. And it levels out small irregularities in the subfloor's surface. A floor can hardly offer more comfort or well-being.

Kronotex Silverline

Information

Technical Data

Use

KRONOTEX silverline wood-fibre insulation is laminated on one side with special aluminium foil, without using any additional adhesives. 
Amongst other things, this aluminium lamination keeps moisture out (acting as a vapour barrier) and shields against electromagnetic radiation (“electrosmog”). 

The six functions of KRONOTEX silverline in detail: 

1. Insulation against footfall sound and room noise 
The most important property of KRONOTEX silverline is its outstanding ability to keep out footfall sound and room noise. The biggest benefit of the aluminium lamination is that it eliminates the need to add PE foil when installing the insulation. Another big plus is that KRONOTEX silverline can be laid without problem on underfloor heating beneath laminate flooring up to nine millimetres thick. KRONOTEX laminate floors are particularly well-suited for applications of this kind. 

2. Additional thermal insulation 
KRONOTEX silverline is excellent for supplementing existing thermal insulation. 

3. Protection from electromagnetic radiation 
The harmful effects of “electrosmog” have been confirmed by the World Health Organisation. Its ubiquity is making it increasingly important for builder-owners and architects to take appropriate steps to block electromagnetic radiation, especially on housing. KRONOTEX silverline is so far the only eco-friendly wood-fibre insulation that provides genuine protection from electrosmog. Measurements by the International Association for Electrosmog Research (IGEF) have shown that KRONOTEX silverline reduces the intensity of electromagnetic radiation by at least 99.999%. The product has been awarded the IGEF test certificate for its excellent shielding effectiveness. 

4. Infrared thermal insulation 
KRONOTEX silverline provides additional thermal insulation by keeping energy-efficient heat radiation inside. Infrared radiation is emitted by space heaters and other sources. KRONOTEX silverline reflects the infrared rays back into the room, thus preventing heat loss. 

5. Vapour barrier 
Another important property of the aluminium lamination is that it blocks water vapour. KRONOTEX silverline is especially effective for this on roofs and walls. It eliminates the need to install a conventional vapour retarder, while scoring points with its other outstanding properties and benefits. 

6. Airtight layer 
One of the essential features of energy-efficient construction systems is a highly air-impermeable building envelope. KRONOTEX silverline makes it easy to create a completely airtight layer that prevents heat loss and condensation. Adhesive aluminium-foil tape is recommended for sealing the butt joints.

IGEF measured the degree to which KRONOTEX silverline attenuates electromagnetic radiation from 20 kHz to 4 Ghz. The values obtained were between 52 dB and 95 dB, depending on the frequency range. This is equivalent to a reduction of at least 99.999%. In other words, only 0.001% of the radiation's amplitude is still detectable right underneath the aluminium-laminated wood-fibre insulation.

Easy to store, transport and install 
‘The product’s multifunctionality minimises storage costs, and the handy packaging units are simple to transport. 

As an alternative to vapour barriers for walls or roofs or as footfall insulation, it’s fast and easy to lay the lightweight yet sturdy sheets, attach them to the substrate and tape over the joints. 

Instructions for Use

On floors: 

• As KRONOTEX silverline is only 5 mm thick, it is quick and easy to cut using a Stanley knife or box cutter. 
• Leave a free space 10 mm wide next to adjoining structures. 
• Lay KRONOTEX silverline on the floor with the aluminium lamination facing down. 

Seal joints using adhesive tape with a divided release film
(http://www.wissenwiki.de/Verarbeitung_%28TESCON_PROFIL%29)

• Before laying the KRONOTEX silverline, pull off one half of the release film and attach the tape along the edge of the aluminium lamination with the other half protruding. 
• Now lay the KRONOTEX silverline on the floor with the aluminium-laminated side down. 
• Pull off the other half of the release film from the tape. 
• Place the next sheet so it abuts the already-laid sheet, then press its edge down against the tape.

On walls or ceilings: 

• As KRONOTEX silverline is only 5 mm thick, it is quick and easy to cut using a Stanley knife or box cutter.
• Attach the KRONOTEX silverline to the substructure using a stapler. 
• To obtain an airtight layer, tape all joints. To avoid reducing infrared absorption, use adhesive aluminium-foil tape. For joining KRONOTEX silverline sheets to adjoining structure, ordinary adhesive or flashing tape is suitable, e.g. from pro clima, Ampack, Siga etc. 

Additional advantages: 

• No leftover adhesive when laminating 
• Easy to cut, e.g. with a Stanley knife
• Recyclable 
• Pleasant to the touch and skin-friendly 
• Environmentally friendly

Information

Technical Data

Compression-resistant yet elastic KRONOTEX sound is an insulating board for effectively reducing footfall and vertical impact sound in laminate and hardwood flooring.

Optimised frequency ranges
This footfall sound insulating board excels with high compression strength and elasticity. KRONOTEX sound consists of natural wood fibres which are three-dimensionally interlinked with environmentally friendly binding fibres using an ecological process. High frequencies are shifted into deeper ranges that are much more agreeable to human hearing.

Improved footfall sound insulation
The insulation shifts the resonance peak from about 800 Hz to around 320 Hz within a more pleasant frequency range. (The measurement report of an independent testing lab is available on request; ask for PB III/S-05-153-6). KRONOTEX sound also substantially improves impact sound insulation, thus greatly reducing noise propagation to floors below. KRONOTEX sound with a thickness of 5 mm attenuates footfall sound by Δ Lw = 21 dB (i.e. compared to a standard bare concrete floor).

Assessment table
The improvement in sound levels achieved with KRONOTEX sound is assessed as follows: 
+ 0.5 dB(A) – Improvement only perceptible under good acoustic conditions
