Thermal Stable Rock Wool Board 600 c Load Shrinkage Class A Non Combustible For Exterior Wall Insulation

Good Thermal Stability Non-Combustible Exterior Wall Rock Wool Insulation Board

This good thermal stability non-combustible exterior wall rock wool insulation board is made from basalt rock wool that keeps its structure and its insulating value across its service range. The material has a high thermal load shrinkage temperature and low shrinkage, so it does not lose thickness or slump when it is exposed to heat, which is exactly what is needed behind facades and around hot equipment.

It is fully non-combustible and also has excellent sound absorption, so a single board meets fire, thermal and acoustic targets on an exterior wall. The board is water-repellent and dimensionally stable and is easy to cut and fix, giving a durable facade insulation that stays flat and keeps working for the life of the building.

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: Why does thermal stability matter?

A: A stable board keeps its thickness and insulating value when heated, so the facade or lining does not degrade or slump over its service life.

Q: Is it non-combustible?

A: Yes. It is an inorganic Class A non-combustible rock wool board.

Q: Can it be used behind cladding?

A: Yes, it suits exterior wall and cladding cavity insulation in a properly designed system.
