CTK Block PRO 40 - 4.0 mm sound absorbing material

CTK Block PRO 40 is a new 4.0 mm final soundproofing material suitable as a top layer on horizontal surfaces of car bodies.

.

Block Pro 40 is the ultimate acoustic membrane material based on a non-woven fabric on a polymer layer with improved adhesive properties. The material guarantees a high index of soundproofing properties. Block Pro is intended to be applied as the final third layer on the noisiest parts of the bodywork. It is applied only on horizontal surfaces. Block Pro is flexible and does not lose effectiveness over a wide range of temperatures. In case of demand for the most effective noise reduction with the smallest possible increase in weight, it is also possible to use the CTK Block PRO 20 variant .

How to apply the cushioning material CTK Block PRO 40?

1) Apply the material as a final layer to the already applied materials  ➡️ CTK PRACTIC,  ➡️ CTK PREMIUM ,  ➡️ CTK ELASTIC ,  ➡️ CTK TEMPO FIX or the brand new  ➡️ CTK ELASTIC F. No degreasing required.

2) Cut the damping material into the largest possible pieces corresponding to the location

3) Apply without heating as a final layer

4) No need for rolling or other processing

HOW TO MUTE THE CAR EFFECTIVELY?

The maximum level of soundproofing of the interior of the vehicle passenger compartment can only be achieved by a complete soundproofing (damping and soundproofing and soundproofing) of all key elements of the bodywork and interior, by installing on these elements in layers (if possible and available space) three different types of most effective materials of the highest class, in which each of them has different acoustic properties, operates in a different frequency range and plays a different role. I'm:

layer 1 - highly effective anti-vibration materials that dampen vibrations and resonances of the body elements and further isolate the interior from external noise, which are high-quality mats based on butyl, aluminum and polymers with the highest possible MLF value ( eg ➡️ CTK DOMINATOR,  ➡️ CTK PREMIUM cushioning mats, ➡️ CTK STANDARD Professional),

layer 2 - foam insulation - acoustic barriers with closed cell structure, which block the entry of road noise into the cabin and further thermally insulate the interior against excessive heating and rapid cooling (e.g. ➡️ CTK ELASTIC , ➡️ CTK ELASTIC F rubber foams, ➡️ CTK TEMPO FIX polyethylene foams),

layer 2/3 - soft and porous sound-absorbing materials with open and / or partially closed cell structure, which, in addition to the sound-absorbing properties, also play the role of shock-absorbing and damping spacers of the resonance of the plastic padding elements and reduce crackling and the creaking of these elements (eg ➡️ CTK SILENCE FIX, ➡️ CTK WAVE FIX sound-absorbing polyurethane foams, ➡️ CTK CAIMAT fleece-based sound-absorbing mats). To obtain the best road noise reduction effect, it is also recommended to install the ➡️ CTK BLOCK PRO acoustic membrane as the last third layer on the lower horizontal parts of the bodywork.
