The key to achieving the greatest performance benefit of insulation in exterior walls is selecting the right product for your project. ROCKWOOL exterior wall insulation products can be used in various applications and with many cladding types to maximize and cater performance to a specific project. With numerous ROCKWOOL stone wool products available, you will find insulation options that support optimizing system cost, wall thickness, fire performance, acoustic performance, and thermal performance for your project.
Key Benefits of Stone Wool Insulation Include:
Fire resistant: Noncombustible, stone wool insulation products in exterior wall applications can slow the spread of fire. Stone wool resists the transfer of heat in a wall assembly that causes layers on the other side to begin burning or smoking.
Sound absorbent: The non-direction fiber orientation and increased mass effectively reduces sound transmission across the wall system, creating quieter spaces to recover and recuperate, contributing to increased health and wellbeing
Vapor-permeable and moisture-resistant: allows water vapor to diffuse through without becoming trapped, increasing the drying potential of the assembly and minimizing the risk of decay, corrosion, and mold, contributing to healthy, comfortable indoor environments.
Durable: Dimensionally stable and providing long term thermal efficiency, stone wool materials are durable and easy to install. Stone wool performance is unaffected by humidity and temperature changes and needs no technical supervision or maintenance throughout the building’s lifetime.
Sustainable: Stone wool insulation is manufactured from one of the world’s most abundant raw materials without the use of blowing agents or toxic flame retardants, stone wool can contribute towards LEED credits for your project
