DIN 4109 specifies requirements and makes recommendations, distinguishing between airborne and impact noise protection.
Airborne noise insulation is an important factor for roofs and walls, and impact sound insulation important for floors and ceilings.

Required properties for effective soundproofing are high density, minimum stiffness, high degree of porosity and very good dampening attributes. GUTEX insulation boards possess these four important characteristics and are therefore ideal for soundproofing application.

GUTEX products make inexpensive, optimum solutions for roofs, walls and floor constructions possible.
