Key benefits

 Reduces vehicle weight when compared with felt, foam and polyester materials.

 Easy to compress and highly conformable, enabling installation in smaller cavities.

 Production costs can be reduced as less material is required.

 Hydrophobic, non-woven structure allows both interior and exterior use without the need for a waterproofing barrier.

 Easily recycled as it is a Polypropylene blend the product resists mould and mildew growth so no odors or material degradation occurs.
