Rockwool insulation boards primarily use natural ore as the main raw material. Here are the performance characteristics of rockwool insulation boards:
Rockwool thermal board is characterized by its strong and durable surface, excellent weight-bearing capacity, and not only withstands impacts but also offers superior wind resistance.
Its chemical properties are also very stable, capable of withstanding high temperatures, acid and alkali, and aging resistance, thus ensuring a long service life.
Efficient and labor-saving, the installation process is extremely simple and straightforward. Modular or assembly installation methods allow for quick completion of the construction.
Rock wool board exterior thermal insulation systems offer advantages such as low thermal conductivity, good breathability, and excellent combustion performance. Let's take a look at how the composition of the rock wool exterior system is structured and its applications.
Firstly, the mineral wool exterior wall system is primarily composed of a bonding layer, insulation layer, coating layer, decorative layer, and accessories. The decorative layer should be made of lightweight functional coatings such as decorative mortar or decorative plaster, or a water-based exterior paint with good breathability. Secondly, the mineral wool exterior wall system can be applied to the energy-saving insulation projects of the exterior walls of newly constructed, expanded, or renovated residential and public buildings, including external wall insulation, non-transparent curtain wall insulation, and fire isolation strips for EPS exterior insulation systems.
Rockwool panel manufacturers have failed to widely promote their products in the external insulation field due to their high water absorption, high energy consumption in material production, low inherent strength, and significant dust damage to workers during construction. In recent years, the introduction of pendulum method production technology and fiber surface treatment processes has significantly improved the overall performance of rockwool panels. Rockwool is an inorganic material made by sintering and spinning fibers, with a thermal conductivity of approximately 0.044 W/m.k. It has low compressive strength, open fibers for good breathability, and certain waterproof and moisture-proof properties after surface treatment. These are Grade A external wall insulation rockwool panels with poor adhesion to the substrate material. The surface of the rockwool panels must be treated with an interface agent before use during construction. They require higher performance in adhesion and crack-resistant mortar.
