The Brundtland commission defined sustainability in 1987 as “Development that meets the needs of the present without compromising the ability of future generations to meet their own needs.”

In line with current understanding, this definition contains environmental, social and economic aspects of human activities in a global context. Environmental aspects would include, for example, efficiency of use of primary and other resources, pollution, waste and recycling. Social aspects concern, for example, the well-being of employees, health and safety, contributions to society at large, corporate citizenship and the long-term viability of business. The economic aspects are exemplified by profitability, efficiency, stakeholder added value and ROI.


Sustainability dimensions and examples

Paroc solutions and materials

We work hard to align our solution development very closely with the user and customer needs that stem from the sustainability megatrend. Paroc is a responsible company that caters for the needs of the present generation as well as those of future generations. Sustainability is central in developing our operations. With our insulation solutions, we provide a means of saving energy. We are very proud that the core business of Paroc contributes to sustainability.

When we discuss passive houses or energy-efficient solutions, we can proudly claim to have pioneered both low-energy house concepts as well as cutting edge concepts for cost optimal energy refurbishments and structural solutions. The development of these concepts has been ongoing in our ENERGYWISE programme since the 1990s.

Requirements for sustainable building are:

  • Efficient use of energy
  • Minimisation of emissions
  • Utilisation of production waste and recycling
  • Ascertaining the service life
  • Flexibility

We manufacture stone wool material for stone wool applications for insulation purposes. As a basis for our products, stone offers many advantages. The raw material is almost undepletable and can be found in abundance everywhere. Due to its composition, the end product is a natural, highly durable fibre product. Stone wool withstands time, fire and water.

We provide you with durable and sustainable products. Our stone wool-based solutions are highly durable and energy-efficient. Stone wool is manufactured from 98 % stone. The stone is molten and spun into fibres. During the manufacturing process a binder is added. This process results in a very durable, heat, fire and sound insulating material. The energy that is used during manufacturing is saved more than a hundredfold during the product’s lifetime.

Life-cycle impacts of PAROC stone wool

PAROC stone wool is an environmentally friendly and efficient way of insulating a building. It also saves costs. Compared to the savings PAROC stone wool generates over its lifetime, manufacturing the material uses only one percent of the energy. PAROC stone wool can also be recycled or disposed of safely at a later stage.

The raw material of PAROC stone wool is over 95 % stone

  • PAROC stone wool is made of natural stone.
  • Stone wool consists of ~98 % air and ~2 % stone fibres.
  • Studies show that PAROC stone wool fulfils the most stringent requirements on emissions into indoor air.
  • Stone is also described as an inexhaustible natural resource: stone will be available for the entire lifetime of humanity.

Energy efficiency

  • For each tonne of CO2 generated in the manufacturing process of stone wool, about 200 tonnes of CO2are saved by its thermal insulation properties over a 50-year period. (Source: EURIMA)
  • Better thermal insulation = less energy needed = great savings!

Environmental management system certificate

  • Paroc has been granted ISO 1400 certificate. This indicates that environmental aspects such as emissions into the air, waste handling, utilisation of natural resources and energy efficiency are paid attention to at Paroc and the environmental impacts of production are constantly improved.

Energy balance is extremely positive

  • Stone wool products save much more energy than required.
  • Producing stone wool requires only half of the energy needed to manufacture other types of insulation (cellulose, flax).
  • The energy balance becomes positive only a few months after installation. (Source: Force Technology/ dk-Teknik)

Waste recycling

  • Waste material generated by cutting boards in production is used as a raw material for new stone wool products, reducing the amount of new stone raw material needed.

Efficient transportation

  • The high compression ratio of stone wool means that low-density products can be packed up to half of their nominal volume → Fewer lorries are required!
  • Although traffic and transportation affect the environment, material transports still have to be taken care of. The transport distances are not long since our factories are centrally located close to the market areas.
  • The objective is to minimise unnecessary idle running and always keep vehicles loaded.
  • A clear increase in efficiency is already evident: transport vehicles are loaded for about 80 % of the distance driven.

Plastic waste

  • Paroc has supported and contributed to the buildup of the plastics collection system in various countries. 
  • In most countries, there are existing systems for plastic waste collection.
  • Paroc also accepts the return of plastic waste to some of its factories.

Pallet recycling

  •  Most of the pallets Paroc uses today are so-called one-way-pallets → Old wooden pallets can be used as an energy source in, for example, private houses or power stations.
  • Specified pallets in good condition can be sent back to the nearest factory.

Pallets as insulation

  • With Roof products in Sweden, Paroc uses stone wool pallets.
  • After transportation, stone wool pallets can be used as part of the insulation in the roof →This means the minimum amount of waste!

Waste re-use

  • Up to 5 % of the used volume becomes waste during installation.
  • We recommend use of the optimal product size available.
  • Waste should be used where it is generated to avoid unnecessary transportation.
  • The stone wool cutting waste can be used as attic insulation together with blowing wool.

Waste back to the factory

  • The pre-fabrication house industry generates up to 5 % of stone wool waste during the process.
  • Paroc has the ability to handle clean customer waste at all sites. An alternative is to send the waste to a blowing wool contractor.
Environmentally friendly 

Make blowing wool

  • The waste can be processed with a special shredder machine to be re-used, for example, as roof insulation.

Demolition: Re-use of used material

  • Used stone wool is suitable for re-use as thermal insulation at a new site, provided that the material can be extracted intact from its previous location.
  • Stone wool recovered from demolition sites can also be crushed and used as frost insulation in lightly loaded soil structures (licensed).
  • Paroc stone wool can be used safely as a landfill or soil structure.
