Many different requirements can be fulfill by using Rock wool. It can be utiliz in lofts, roofs, cavities, walls, pipes wall structures, solid walls.


The European Insulation Manufacturers Association (EIMA) has said the following: Rock wool is among the most closely scrutinize products in the construction industry. Over the past five decades the renown scientists from across U.S. and Europe have complet more than 1000 tests to verify that the material is safe for be use in all kinds of constructions.


The Rock wool will not cause flames, spread flames because it is practically incombustible. A structure that is construct with Rock wool improves its fire protection instantly.

High Acoustic Performance

The structure and structure Rock wool is porous and elastic that allows it to absorb the sound. It is the ideal solution to block out the transfer of sound between rooms or neighbors.

High Thermal Performance

Rock wool is able to withstand temperatures that can reach 400o C which is why it provides a remarkable thermal performance. That makes it the perfect material for insulating energy facilities and factories.

Recycling Materials Are A Great Option For Use

Glass is the principal ingredient utilize in the production of Rock wool, the product is able to be made from recycle materials. For example, ISOVER use the highest possible grade of glass (86 percent) during their production process.

Reduces CO2 Emissions

Installing a large (270mm) Rock wool in an uninsulated loft could reduce the amount of CO2 annually household. Therefore, the Rock wool can improve the sustainability of the home and aids in reducing energy consumption and fuel consumption, saving both the energy and the money of customers.

The Market Overview

The world Rock wool market growing quickly and will continue to grow rapidly over the next few years. According to a report from Research Dive, the global market for Rock wool is project to earn $16,031.8 million, and is expect to grow by a CAGR of 6.6 percent from 2019 to 2026.

This is in part because of the growing usage for Rock wool for the building and construction sector for commercial and residential infrastructures. The most prominent players in the market are embracing a variety of new trends in the Rock wool markets, as well as numerous strategies such as mergers, acquisitions and joint ventures in order to stand out from the rest of the competitors.

Enhancing Sustainability And Energy Efficiency By Using Rockwool Applications

There are many insulation materials that are on the market at present. Each kind of material comes with its advantages and disadvantages. Before deciding which material for your attic insulation, it is important to know what the different materials can do to suit your needs. Let’s take a look at five most commonly used types of insulation materials.


Fibreglass is probably the most popular insulator on the market. It is create using glass yarns into it’s insulation.

Fibreglass is a non-combustible product that requires careful handling since it’s made of glass, which could harm the lungs, skin even your eyes, if it cracks.


Cellulose is an insulating substance made of recycled cardboard, paper and other materials that are loose. It is green and one of the most effective insulators available on the market.

Cellulose is an excellent product particularly for a defense to fire damage as it contains almost zero oxygen. If a fire hazard begins in your attic it will help minimize the damages.

Polyurethane Foam

Polyurethane isn’t a typical insulation material, but it can be an excellent choice for insulation. It is composed of polyol, Isocyanate and other auxiliary materials such as catalysts, stabilizers, as well as foaming agents. 

The Rockwool rwa45 wickes can also be found in low-density foams, which are spray on areas that are not insulat. Polyurethane foam is an excellent thermal insulator that is ideal for insulation of attics.


If you are looking for a fantastic insulation that can be use for both temperature and sound that is waterproof, then thermoplastic polystyrene is a great choice. There are two kinds of polystyrene: (XEPS) extruded, also known as Styrofoam and (EPS) extruded as expanded. The two types differ in price and performance ratings.

How Does Rockwool Compare With Other Common Insulation Alternatives?

Rockwool Rwa45 insulation provides high-performance and an extremely low environmental impact. But, if you’re facing budget limitations the fiberglass insulation is likely to remain the most affordable alternative.

However Blown-in insulation may be a better option for homes with elaborate attics or roofs with numerous nooks and crannies. This type of insulation is able to perform the best job at filling in those difficult-to-access gaps that may be difficult to fill with insulation.

Spray foam insulation similar to Rock wool, comes with an R-value that is high and also can be fitte into small areas. It is, however, one of the most expensive insulation choices and could negatively influence the climate in the event that you fail to select a low temperature potential for global warming (GWP) alternative.

Rigid board insulation, a different alternative, is available in panels that are able to and quickly be cut into size. They are made of polystyrene or polyisocyanurate as well as polyurethane. They can have a substantial environmental impact.

Structural Insulated Panels (SIPs) typically provide an excellent insulation choice for homes constructed according to the global passive house standard since they are structural elements that are airtight. SIPs are, however, not a simple option to incorporate into renovations to homes.

Like any sustainable building element there isn’t a “one size will fit for all” solution. For insulation, the most effective solution will be determine by a variety of aspects, such as the house’s position and orientation, the construction quality of the home and the budget of the homeowner, along with other climatic and context aspects.
