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.
Updated data sheets for Board / BW Board, Module and Rope & Glass Fiber Tape are not yet available — until then, these products link directly to the material enquiry.
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.
