Roof stiffener - damping and stiffening of pavilions

In the race to reduce weight, the roof stiffener has become an essential part integrated right from the vehicle design phase in order to limit indentation phenomena (sheet metal blistering), significantly reduce external noise and eliminate acoustic buzzing. Tailor-made for each type of vehicle so as to be perfectly adapted to the shape of the roof pavilion, it is fixed by means of adhesive tapes integrated into the part or by an adhesive application system during assembly. As a specialist in adhesive solutions, Adhex offers manufacturers adhesives of different densities, specially designed for the fastening of roof stiffeners. These adhesives allow to fix the stiffeners on assembly lines in a simplified way (by simple pressure) or fully automated. Once positioned between the sheet metal and the headliner, the stiffener becomes completely invisible to the customer and does not show any marks or distortion. The roof stiffener improves the acoustic comfort of the vehicle, preventing buzzing, vibration sensations or rain noise, whether the vehicle is stationary or moving. The stiffeners designed by Adhex can indeed integrate acoustic damping plates (IFF, soundproofing fuse in sheet form), guaranteeing the effectiveness of the device. The roof stiffener also avoids the blistering of the roof sheet (indentation). Guaranteed for a shelf life of 15 years and tested by a bending test, Adhex roof stiffeners meet all safety standards in force in the automotive industry, in particular with regard to fire resistance (fireproofing) or volatile organic compounds (VOC).
