The panels are made of recycled polyurethane foam at a density of 100 kg per cubic metre, faced with an oil-resistant aluminium foil that can be wiped clean, and treated with a fire-resistant formula that withstands up to 200 degrees C.

## 🔌 Function

Absorbs airborne engine noise inside the engine space so less of it reaches the accommodation.

## ⚠️ Common Signs of Failure

-   Engine noise noticeably louder in the accommodation than it used to be
-   Panel sagging away from the bulkhead
-   Facing torn, oil-soaked or crumbling
-   Foam compressed flat and no longer springy
-   Loose fragments of foam collecting in the bilge

## 🛠️ Service Notes

-   Check you have the depth for 30 mm before ordering - 41103800 is the 20 mm and 41103802 the 50 mm version of the same sheet
-   This version has no adhesive backing, so allow for mechanical fixings or insulation hangers
-   Cut to shape with a sharp knife, keep the joins tight and cover them with foil tape so noise cannot leak and water cannot get into the foam
-   Fit the sheets so the joins are as tight as possible and cover them with foil tape, otherwise noise leaks through and water can be absorbed by the material
-   Sound insulation hangers can be used for convenient mounting
-   Choose the panel thickness against the engine's own noise characteristics across the 100-8000 Hz range; sound absorption is rated to DIN 52215
