Its high thermal efficiency reduces energy bills for heating and cooling in residential buildings due to the outstanding thermal resistance of the wool. The thermal resistance of a construction material is measured by what’s known as the R-value, with a higher number indicating that a substance can better resist thermal transfer. According to the U.S Department of Energy, fiberglass offers an R-value of 2.2 to 2.7 per inch, while Rockwool has an R-value of 3.0 to 3.3 per inch.
Rockwool offers noise insulation due to its innovative materials that have higher densities and random fiber standard orientation that trap sound waves and deadens vibration time. For this reason it is perfect choice for spaces where the occupants are looking to minimize noise such as offices, bedrooms, meeting rooms or accommodation close to busy roads.
It offers fire protection to the building and improved safety because it is made of rock that is fire resistant.
Rockwool is a breathable material allowing moisture to escape from the construction. This reduces the risk of mound and bacterial growth on the inside of the property.
It constitutes a compression-resistant material that can be used as roofing boards or bonded panels. So it is ideal for thermal applications on domestic buildings such as extensions and loft conversions. It also useful for buildings subjected to change of use or layout that and there is a need to add internal partitions.
It offers quick and easy installation providing airtightness to the building envelope.
Improves the thermal comfort and air quality of the building offering a healthier environment to the occupants.
Provides long term performance due to the unrivalled durability of rock that has unlimited lifetime. So there is no need for maintenance increasing the payback time of the intervention.
It has minimum environmental impact because it reduces carbon footprint due to its natural origin and hazardous-free classifications that offer minimum embodied carbon. Additionally, it reduces the use of non-renewable energy sources such as gas and electricity contributing to air pollution reduction.
Rockwool itself is sourced from natural and sustainable raw materials and perhaps more importantly it can be completely recycled when the building is no longer in use without producing waste – All of the Rockwool waste can be reused as a raw material in the manufacturing process, producing brand new insulation.
