Isover AcustiPAR 4+ – 45-70 mm thermal-acoustic glass wool roll

Isover AcustiPAR 4+ – glass wool roll for thermal and acoustic insulation of wallsh2>

Isover AcustiPAR 4+ is a glass wool roll specifically designed for thermal and acoustic insulation of plasterboard walls and brick false walls. It's lightweight, easy to handle, and easy to cut, designed for drywall construction sites where high acoustic performance, good thermal resistance, and fire safety are required.p>

Fields of application

• Acoustic and thermal insulation of plasterboard walls with metal studs.
• Internal false walls on brick walls, perforated blocks or existing masonry.
• Vertical cavities where improved living comfort and acoustic privacy are required./li>
• Residential, tertiary and commercial dry systems requiring non-combustible materials.

Main advantages

• Excellent sound insulation: the fibrous structure of glass wool helps reduce the passage of airborne noise between adjacent rooms, improving the acoustic comfort of homes, offices and public spaces.
• Good thermal performance: the declared thermal conductivity λD equal to 0.038 W/mK helps limit heat loss and contributes to making environments more stable and comfortable in both winter and summer.i>
• Fire safety: the material is classified intostrong>Euroclass A1 (non-combustible), therefore it does not feed the fire and helps increase the safety of the wall system.there>
• Sustainability and indoor air qualityrong>: produced in Italy with a high recycled glass content and a natural binder, it is designed to reduce environmental impact and indoor emissions.i>
• Quick and easy installation: supplied in compressible rolls, it is lightweight, easy to handle, cut and insert between the uprights, reducing installation times and waste on site./li>

Stability over time/strong>Glass wool is rot-proof, resistant to mold and parasites, and, under correct operating conditions, maintains its thermal and acoustic performance over time./li>

Indicative technical characteristics

Formats and combinations available on our shop

On this site Isover AcustiPAR 4+ is offered in two thicknesses, depending on the required acoustic and thermal performance and the available wall thickness:/p>

Combinations can be managed in Prestashop as product variants (e.g. "Thickness" attribute 45 mm and 70 mm, with yield in m²/package indicated in the individual combinations)./p>

Installation guidelines (not a substitute for the technical data sheet)

1. Check that the metal structure of the wall or false wall is correctly sized and fixed according to the chosen plasterboard system.
2. Cut the roll of glass wool to sizeas necessary, adding a small margin to ensure adhesion between the uprights.there>
3. Insert the material into the gap between the uprights, without excessive compression and without leaving cracks or voids that would reduce performance.there>
4. Complete the system with the coated plasterboard panels and seal the joints according to the drywall system manufacturer's instructions.
5. For the correct sizing of the stratigraphy and the verification of the thermo-acoustic performance, always refer to the designer and the official Isover documentation.
