Rigid Rock Wool Acoustic Board 1200x600mm High Density Sound Absorption For Exterior Wall Facade

Rigid Sound Absorption Performance Exterior Wall Rock Wool Insulation Board

This sound absorption performance exterior wall rock wool insulation board is engineered for buildings where acoustic comfort matters as much as thermal performance. The open, fibrous structure converts sound energy into heat, giving strong sound absorption and cutting the airborne noise that travels through walls, facades and partitions, while the same structure delivers excellent thermal insulation to lower heating and cooling demand.

As an exterior wall insulation it is dimensionally stable and non-combustible, so it keeps its thickness and its fire safety behind cladding, renders and rainscreens. The board is rigid enough to stand in vertical cavities and is easy to cut around openings and fixings, which keeps installation fast and joints tight for consistent acoustic and thermal results across the facade.

Supply and Service

Myreal rock wool products are supplied in polyethylene packages (or cartons for pipe) to make handling, transportation, storage and identification easy, and they should be stored indoors or under a waterproof covering. Special sizes, thicknesses and facings can be produced to order. Aluminium foil facings and other waterproof facings are available for the board, pipe and blanket ranges. Every batch is checked for density, thermal conductivity and dimensional accuracy before dispatch. Rock wool is also a sustainable, recyclable insulation: it is made largely from abundant volcanic rock, contains no asbestos and no ozone-depleting blowing agents, and it can help projects earn green-building credits. It is chemically stable, non-corrosive to steel and aluminium in normal use, and it will not support mould growth. If you would like the full technical data sheet, a free sample, the applicable test report or a project specific quotation, our engineering team will gladly help you choose the right model, thickness and facing for your building or industrial project. Tell us your application, working temperature and target performance and we will recommend the most cost-effective MYREAL rock wool solution.

Note: thermal conductivity, density, hydrophobicity, compressive strength and fire rating vary with the product specification. Please refer to the technical data and test report of the specific MYREAL model before use, and do not apply one model's data to all products.

Frequently Asked Questions

Q: Does it reduce noise?

A: Yes. The fibrous rock wool absorbs sound energy, so it lowers airborne noise through walls and facades and improves acoustic comfort.

Q: Suitable for facades?

A: Yes. It is designed for exterior wall insulation behind cladding, render or rainscreen systems within a properly designed build-up.

Q: Is it fire safe in a facade?

A: Yes. It is Class A non-combustible and does not add fuel to a facade fire.
