CTK Sandwich 5.0 is a premium 3-layer (multi-layer) soundproof material made of polymer mixtures and ALU foil.

The sandwich consists of a butyl material with an ALU foil that absorbs vibrations (CTK Premium) and a noise-absorbing material (CTK Elastic). It can be used on any surface of car floors or even doors. It is resistant to water and moisture. Sandwich was created to reduce installation time.

.

The main advantage of the CTK Sandwich 5.0 material

It consists of a lightweight butyl layer, an ALU foil and a polymer layer made of closed pulp.

The material fully replaces the application of 2 separate layers -  ➡️ CTK PREMIUM and  ➡️ CTK ELASTIC

Full resistance to water and moisture

The extreme adhesive layer guarantees 100% functionality throughout its lifetime

Streamlines the installation process by applying 2 layers in 1 step

Temperature stability in the range of -45 to +130 degrees

.

Recommended use of CTK Sandwich 5.0

CTK Sandwich 5.0 can be applied completely independently or as the first layer. Replaces layering with 2 types of materials. It is suitable for application to the inside of the door, on the roof, on the floor, the central tunnel or underpasses.

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.
