Hushfoil™ Aluminum Foil Heat Insulation Sound Cotton

Hushfoil Aluminum Foil Heat Insulation Sound Cotton is a flaky sound insulation cotton made from rubber and plastic material with a microporous form. It carries a normal sound insulation grade of 25-30db and is designed with an adhesive-backed layer paired with aluminum foil for engine and hood applications.

This sound insulation cotton has low bending strength and medium compressive strength, giving it a flexible-but-supportive feel in flat, flaky sheets. The adhesive backing lets it be applied directly to a surface such as a hood or engine bay panel.

Why it works

• Aluminum foil facing combined with an adhesive backing supports mounting to engine and hood surfaces without extra hardware.
• Medium compressive strength material holds its shape under moderate pressure while remaining flaky and low in bending strength for shaping around panels.
• Rated at a normal 25-30db sound insulation grade for noise reduction applications.
