Butyl rubber damping sheets faced with aluminium, for the panels that ring and rattle - door skins, boot floor, wheel arches, bulkhead. Butyl adds mass and stops the panel resonating, which is a different job from putting foam over the noise.
Key features
Butyl rubber composite with an aluminium foil face
Absorbs vibration and stops thin metal panels resonating
Strong self-adhesive backing that holds on vertical panels
Flexible, so it presses into curves and around bracing
Cuts with scissors or a knife to fit round brackets and wiring
Material: butyl rubber composite with an aluminium facing
Backing: self-adhesive
Fits doors, boot, wheel arches, bulkhead, floor and roof lining
Also suits speaker enclosures and van conversions
How to use it
Clean and dry the panel, cut the sheet to shape, then peel the backing and press it down from the centre outwards. Roll it flat so it bonds hard to the metal - butyl works through contact. Aim for roughly a quarter to a half of each panel covered; full coverage adds weight for little extra benefit.
