Unilin’s stonewool insulation is non-combustible, Euroclass ‘A1’ insulation, also known as mineral wool.

Stonewool insulation can be used in any project when aiming to achieve a uniform solution and provide resilience during the build. Stonewool Rainscreen is a high specification Stonewool for cladding applications that provides high-density insulation, the reduction of heat loss in your build, high acoustic performance lower sound transmission and finally the ability for use in high-rise projects

SW/RS High specification Stonewool for cladding applications is suitable for use in ventilated facade, rainscreen and framing applications and closed systems such as curtain walling.

Stone wool insulation delivers reliable performance in projects where the highest level of fire protection is required. It is produced by melting natural minerals, such as volcanic rock, and spinning them into fibres that form a dense, non-combustible durable insulation slab.

Our Stonewool range offers a thermal conductivity of 0.036 W/mK.

It is also classed as a non-combustible, Euroclass ‘A1’ insulation.

Stonewool mineral wool insulation can be used within a rainscreen application for walls or for Soffit Applications

Where a project requires a A1 reaction to fire classification, good acoustic performance, or involves constructing a high‑rise building, stone wool is the most appropriate insulation to specify.

Stonewool can be used in many applications or projects. Whether you are looking at a new build, a renovation project, commercial or residential, stonewool insulation can be considered for your project.It can be used in wall and soffit applications, making it a viable solution for a variety of constructions. 

Euroclass A1 Fire classification

Suitable for use in high-rise buildings

Suitable for a variety of applications

Dense insulation solution Improved Acoustic Performance

Stonewool insulation reduces the transfer of heat through a building’s walls, soffits, and other structural elements. (Stonewool can also contribute to the fire protection as part of the overall building system)

Heat conduction and lambda value

As it has a low thermal conductivity it is difficult for heat to pass through it,which makes it is such a good insulator.

R-Value

A low lambda value (Thermal conductivity) results in a high R-value or thermalresistance, a measure by which we assess specific insulation products in relation to their insulation thickness. This thermal resistance quantifies the area and temperature difference needed to transfer 1W of heat energy. The higher the R- value, the lower the amount of heat loss.

The lambda value of stonewool insulation ensures that installers can achieve high levels of thermal performance while maintaining comfortable insulation thicknesses.

Stonewool Insulation and Reaction to Fire

The fire rating of Unilin Insulation Stonewool range has a Euroclassclassification of A1. This applies to our SW/RS and SW/ST products. It is important to check the fire rating of each product when specifying.
