Party wall insulation by Isover is a low-cost, acoustic insulation roll that reduces the sound transmission across a masonry party wall while also reducing air movement within the cavity. It enhances the thermal performance of the masonry party walls. The insulation rolls by Isover are available in 75 and 100mm thicknesses. They are strong, durable and flexible acoustic insulation rolls that come in ready-cut - 2 x 455mm that can easily fit between standard wall tie spacing.

The medium-density mineral wool insulation roll is primarily used for sound insulation in party wall structures. The party wall insulation is known for its outstanding acoustic performance. When used as part of a Robust Detail structure, it helps to prevent unwanted noise between attached properties. It can help achieve the required U-value as stipulated in the building regulations. The party wall insulation rolls are environment friendly and do not contain or emit any harmful gases.
