Protect Foam dB 4802

Thermal and acoustic barrier for flexible applications

Protect Foam dB4802 is an innovative membrane designed for thermal and acoustic insulation in industrial and architectural environments. Engineered for applications such as flexible doors, partition curtains, insulated tent walls, or industrial machine enclosures, it delivers comfort and performance in demanding conditions.

Flexibility, Light Weight, Performance

Featuring a foamed PVC structure with a double-sided lacquer finish, Protect Foam dB4802 combines light weight, flexibility, and insulating efficiency.

• Foam core construction with double-sided lacquer: strength, flexibility, and durability
• High flexibility: easy installation, even on complex structures
• Excellent thermal insulation: U-value of 3.6 W/m²·K
• Strong resistance to UV exposure, moisture, and mold
• Fire rating: M2 according to NF P 92-507

Versatility at the Core of Protect Foam Performance

The key advantage of the dB4802 membrane lies in its versatility, achieved through a balanced combination of thermal insulation, sound absorption, and installation flexibility. Designed to adapt to a wide range of configurations—from flexible doors and partition curtains to machine acoustic insulation and insulated tent walls—this foam membrane is a multifunctional solution for demanding environments.

Its slim 5 mm profile, controlled weight, and excellent flexibility allow for quick installation, even in confined spaces or on modular structures. The double-sided treatment and resistance to UV, moisture, and mold ensure durability for both indoor and outdoor use.

With sound reduction of up to 24 dB (dB4802), depending on frequency, and a strong thermal transmission coefficient (U = 3.6 W/m²·K), it provides a comprehensive solution for thermal and acoustic comfort in industrial buildings, logistics halls, and temporary structures.
