The 125mm Isover RD Party Wall Insulation Roll is a high-quality insulation product designed to provide optimal soundproofing and fire protection for party walls in residential and commercial buildings. This insulation roll is made from high-density mineral wool, which is a natural and sustainable material that offers excellent thermal and acoustic performance.

125mm Isover RD Party Wall Insulation Roll is manufactured to the highest standards, using sustainable materials and advanced production techniques. The product is fully compliant with all relevant building regulations and has been tested and certified by independent third-party organisations to ensure its performance and safety.

Isover is a leading manufacturer of insulation products, with a global reputation for quality, innovation, and sustainability. The company has over 80 years of experience in the industry and has a proven track record of providing high-quality insulation solutions for residential, commercial, and industrial applications.

The benefits of 125mm Isover RD Party Wall Insulation Roll

One of the main benefits of the 125mm Isover RD Party Wall Insulation Roll is its ability to reduce noise transmission between adjoining properties. This makes it an ideal solution for party walls that separate apartments, townhouses, or commercial units. The high-density mineral wool used in this insulation roll is specifically designed to absorb sound waves, which helps to reduce the amount of noise that passes through the wall.

In addition to its acoustic performance, the 125mm Isover RD Party Wall Insulation Roll also offers excellent fire protection properties. It has been tested to the highest standards and is rated as Euroclass A1, which means it is non-combustible and will not contribute to the spread of fire. This makes it an essential safety feature for party walls, particularly in buildings where multiple occupants are present.

Installation of the 125mm Isover RD Party Wall Insulation Roll is straightforward and can be completed by a professional installer or a competent DIY enthusiast. The insulation roll is supplied in a convenient and easy-to-handle roll format, which can be easily cut to size and fitted between the party wall frames. The insulation roll should be installed in a way that maximises coverage and minimises gaps and seams, to ensure optimal acoustic and thermal performance.

Insulation for Masonry Cavity Separating Wall

The primary objective of a separating (Party) wall is to ensure effective acoustic isolation, preventing the transmission of airborne sound between two adjacent dwellings. This significantly enhances the acoustic comfort for residents in both properties. The minimum acoustic standards are established by Approved Document E (for England & Wales) and Section 5 (for Scotland). However, it is often advisable to surpass these standards when feasible.

One way to confirm compliance with these standards is by employing Robust Details. Alternatively, an acoustician can be commissioned to assess and validate the design of the separating wall.

In the context of masonry cavity separating (Party) walls, the preferred insulation material is typically a glass mineral wool roll such as this Isover RD Party Wall Roll. The benefit of using Isover RD Party Wall roll is that it can be integrated into the construction of the separating (Party) wall within the central cavity, placed between the two rows of blockwork. This ensures that the necessary level of sound reduction, in line with the requirements of Approved Document E (England & Wales) and Section 5 (Scotland), is achieved.

An additional advantage of adhering to specific specifications and correctly installing insulation within the cavity is the potential for achieving a zero effective U-value in SAP, as detailed in the ISOVER RD Party Wall Roll product datasheet. This not only reduces energy consumption but also simplifies compliance with Building Regulations.

How to install 125mm Isover RD Party Wall Insulation Roll

Installing the 125mm Isover RD Party Wall Insulation Roll is a straightforward process that can be completed by a professional installer or a competent DIY enthusiast. Before installation, it is important to ensure that the party wall frames are clean and free from any debris or obstructions that could affect the insulation’s performance.

The insulation roll is supplied in a convenient and easy-to-handle roll format, which can be easily cut to size if needed and fitted between the party wall frames. The insulation should be installed in a way that maximises coverage and minimises gaps and seams, to ensure optimal acoustic and thermal performance.

To install the insulation roll, start by measuring the length and width of the party wall frame, and cut the insulation roll to the appropriate size using a sharp knife or scissors. The insulation roll can be held in place using insulation hangers, which should be spaced at regular intervals along the length of the party wall.

Once the insulation roll is in place, ensure that it is fully secured and compressed between the party wall frames, without any gaps or seams. Any excess insulation material can be trimmed using a sharp knife or scissors.

It is important to note that the 125mm Isover RD Party Wall Insulation Roll should not be compressed, as this can reduce its acoustic and thermal performance. Additionally, it should not be installed in damp or humid conditions, as this can affect its insulation properties and lead to mould growth.

How to correctly store 125mm Isover RD Party Wall Insulation Roll

Proper storage of the 125mm Isover RD Party Wall Insulation Roll is essential to ensure its performance and longevity. When storing the insulation roll, it should be kept in a dry and well-ventilated area, away from direct sunlight, moisture, and extreme temperatures.

Ideally, the insulation should be stored in its original packaging, which is designed to protect it from damage and exposure to the elements. If the original packaging has been damaged or lost, the insulation roll can be wrapped in a moisture-resistant material, such as plastic sheeting or tarpaulin, to protect it from moisture and dirt.

When storing the insulation roll, it is important to avoid compressing it, as this can affect its acoustic and thermal properties. Instead, the roll should be stored upright, and any weight or pressure should be evenly distributed along its length.

By following these simple storage guidelines, building owners and installers can ensure that the 125mm Isover RD Party Wall Insulation Roll remains in optimal condition and performs effectively when installed.
