Fibre blankets, folded modules, boards, paper and seals — as ASW for the hot zone and as bio-soluble AES grade where classification-free material is required. From a single source: material selection, cutting, delivery and installation by our own fitters.
The number in the product name is the classification temperature to DIN EN 1094-1 — not the continuous service temperature. For amorphous wools, the latter is typically 100–150 °C lower.

Every product with a data sheet for direct download — no form required.
Long-fibre, double-needled blankets based on alumina/silica for back-up insulation, expansion joints and roof insulation.
Bio-soluble silica-based blanket — exempt from classification under Note Q of the CLP Regulation and therefore free of hazard labelling.
Folded modules with anchoring system for hot-face all-fibre linings — low thermal mass, short heat-up times, fast installation.
Rigid fibre boards and vacuum-formed parts for mechanically loaded zones, furnace doors, covers and load-bearing insulation layers.
Thin, flexible ceramic fibre paper with a smooth surface for seals, interlayers and sealing work.
Large-format calcium silicate board for load-bearing insulation — high compressive strength with low thermal conductivity, outside the scope of TRGS 558.
Microporous board with the highest insulating performance per millimetre of build height — for restricted installation space and fibre-free bills of materials, e.g. in battery energy storage (BESS).
Round ropes and glass cloth tapes for furnace door, bogie hearth and penetration seals, and as protective wrapping for hot-gas lines.
The first question that now determines every material selection — technically and in regulatory terms. We assess it together with you before you order.
ASW/RCF — alumino-silicate wool or refractory ceramic fibre
Fibres of alumina and silica (Al₂O₃ / SiO₂), classified up to 1260–1430 °C. Harmonised classification as carcinogen category 1B (H350i), on the REACH Candidate List, handling in accordance with TRGS 558.
Your products: SOLUT Blanket ST, HA and HT as well as Module, Board and Paper in ASW grade.
AES — alkaline earth silicate wool
Fibres of silica with calcium and magnesium oxide — recognisable in the data sheet by SiO₂ / CaO / MgO instead of Al₂O₃ / SiO₂. They dissolve quickly in lung tissue (“bio-soluble”), are therefore exempt from classification under Note Q of the CLP Regulation and do not fall within the scope of TRGS 558. Practical limit usually below approx. 900 °C continuous temperature.
Your products: the BW types — SOLUT BW Blanket, BW Board, BW Paper.
Anyone looking for “bio-soluble” is looking for AES — which is why every product card carries the abbreviation at the top as an identifier, not just in the body text.
Exempt from classification as carcinogenic under Note Q of the CLP Regulation — therefore free of hazard labelling and outside the scope of TRGS 558.
Harmonised classification as carcinogen category 1B (H350i) and on the REACH Candidate List since 19 December 2011 — but technically often without an alternative.
By industry and component — with the product typically used there.
Directly downloadable, no form required. Safety data sheets and the information under REACH Art. 33 are sent on request.
All data sheets are available for download in seven languages — you automatically receive the version in your selected language.
No. That is the classification temperature to DIN EN 1094-1 — the temperature at which linear shrinkage does not exceed 4 % after 24 hours of heat treatment. The continuous service temperature of amorphous wools is typically 100–150 °C lower and depends on the lining layer build-up, the cold-face temperature and the operating mode.
Alumino-silicate wool (ASW/RCF) has a harmonised classification as carcinogen category 1B, H350i, and has been on the REACH Candidate List since 19 December 2011. Bio-soluble AES wool is exempt from this classification under Note Q of the CLP Regulation and carries no hazard labelling. As a mechanical fibre it remains a skin irritant — dust avoidance is advisable there too.
Bio-soluble fibres meet at least one of the four criteria of Note Q, for example a weighted half-life of fibres longer than 20 µm of less than 10 days in the inhalation biopersistence test. The catch: the practical service limit of AES wools is typically below approx. 900 °C — above that, ASW often remains technically necessary.
Yes. TRGS 619 requires a documented substitution assessment where technically and economically feasible. The result belongs in the risk assessment. The assessment covers service temperature, insulating performance, long-term behaviour and service life — we supply the technical data for this evaluation.
Under TRGS 558 this depends on the exposure category: category 1 respiratory protection recommended, category 2 FFP2/P2 at exposure peaks, category 3 FFP3/P3 or powered respirator mandatory plus type 5 protective suit to DIN EN ISO 13982. TRGS 558 does not apply to bio-soluble AES wool.
High-temperature insulation wool that has not been thermally stressed falls under waste code 170603* (hazardous waste) and must be packed dust-tight. For wool that has been thermally stressed above 900 °C, TRGS 559 must additionally be observed because of possible cristobalite formation.
Blankets for flexible back-up insulation, compensation strips and seals. Folded modules for hot-face all-fibre linings of cyclically operated furnaces — low thermal mass, short heat-up times. Boards for rigid, mechanically loaded zones and as load-bearing insulation layers.
Fibre-free materials do not fall within the scope of TRGS 558. Microporous boards additionally offer the highest insulating performance per millimetre of build height — decisive when installation space is limited or the customer requires a fibre-free bill of materials.
No. Fibre products belong in the back-up insulation behind the refractory wear lining, not in contact with the melt.
Yes — as cut pieces, strips, special thicknesses, roll widths to specification and as vacuum-formed parts to drawing. A roll width of 1220 mm is available on request.
