9. Which qualities does mineral wool have?

Mineral wool offers optimal heat, sound and fire protection from the cellar up to the roof. By its simple handling mineral wool can be processed without problems. In addition, mineral wool is a products gained from natural raw materials, insusceptible to ageing over decades and hence particularly economic.

10. Are the good qualities of mineral wool also valid for cover plates produced of it?

Yes, on a full scale. The processing into solid plates leads to end products which keep all typical qualities of the mineral wool.

11. How insusceptible to ageing are insulation materials made of mineral wool?

Mineral wool is extremely insusceptible to ageing thus the insulation effect remains unchanged within the construction for many decades.

12. Can insulation with mineral wool reduce the risk of fires?

Yes, because mineral wool is a non-combustible insulation material and offers an important contribution to the preventive structural fire protection. No toxic smoke gases arise either.

13. Mineral wool can contribute to reduce the fire risk. Does this also apply to cover plates made of mineral wool?

Yes, this is one of its most important qualities. Depending on the implementation it meets the building requirements of being non-combustible or hardly inflammable. On the market there are offered plates which reach a fire delay of up to 2 hours and thus correspond to the fire resistance class F 120.

14. Can these cover plates made of mineral wool also fulfil additional functions apart from design intentions?

Yes, mineral wool plates are offered by manufacturers in a large variety of implementations, e.g. with additional functions like fire protection, soundproofing, acoustics, cooling or ventilation.

15. Does mineral wool offer also protection from heat during summer?

Yes, a good insulation in connection with warmth storing mass in the inside area offers a very good summery thermal protection.

16. Can mineral wool get mildewy?

No, mineral wool does not absorb humidity and does not represent any nursing medium either. Mould growth on walls and covers appears frequently due to construction damages and should be checked by an expert.

17. Can mineral wool be processed by do-it-youselfers (hobby-builders)?

Yes, mineral wool can be processed without problems from the cellar up to the roof by the hobby-builders in the own home. The simple handling of mineral wool is still supported in addition by a versatile choice of system products for different problem solutions. The processing of mineral wool, e. g. at façades or at the commercial surface engineering should however be executed by professional craftsmen.

18. Does mineral wool release fibre dust after the installation?

No, examinations ordered by the department of the environment prove that no significant fibre dust is released into living spaces and public utilities which are insulated with mineral wool.

19. Can mineral wool be touched with bare hands?

Yes, mineral wool insulants with the RAL quality mark can be touched with bare hands. Preventively one should wear working gloves as well as and wash hands after working with mineral wool. If sensitive skin reacts with itching, it is a temporary symptom which abates by itself.

20. Do mineral wool products provide the same quality and safety like other insulants?

Yes, they offer at least the same quality and safety. They have a reasonable price/performance relationship and are durable for decades. The RAL quality mark guarantees the checked quality and safety of mineral wool insulants concerning fire protection quality, too.

21. How high is the safety standard of products with the RAL quality mark?

Mineral wool products with the RAL quality mark comply with a very high safety standard. Before the products of a manufacturer are marked with the RAL quality mark, the mineral wool manufacturer must undergo the severe quality examinations of Gütegemeinschaft Mineralwolle e.V.. These proofs are provided by independent examining institutes. Even after awarding the RAL quality mark the production of the manufacturers is under regular independent control.
