Butyl Sound Deadening Sheets, 5 mm - 10 Pack, 250 x 180 mm

A pack of ten butyl sound deadening sheets with an aluminium face, 250 x 180 mm each, 5 mm thick. Butyl is the heavy, sticky type that kills panel ring rather than just muffling it.

Key features

• Ten sheets, 250 x 180 mm, 5 mm thick, about 0.45 square metres in total
• Visco-elastic butyl rubber with an aluminium outer layer
• Damps vibration, so panels stop resonating
• Stays flexible, so it presses into curves and around edges
• Water resistant, and works in heat and cold
• No asphalt smell
• For cars, vans, motorhomes, machinery and speaker enclosures

How to use it

Clean and degrease the panel, cut a sheet to size, peel the backing and roll it down hard from the middle outwards. Full contact is what makes butyl work, so use a roller.

Good to know

We hold no fire rating for this material, so do not fit it against exhaust parts or any other hot surface. Full coverage is not needed: around 25-30 percent of a panel, placed in the middle of the flat areas, does most of the work.
