Why Stenvak for Industrial Projects
Direct China Pricing
Skip importer margins. 30-50% below European brand pricing for the same A1 fire-rated stone wool. 1 container MOQ shipped from Qingdao Port.
Real Certifications, Real PDFs
FM Approved + CCS Works Approval (valid through 2028) + CE EN 13162 (Intertek NB 2649, valid through 2026) + KS L 9102 + GOST + RoHS. Every certificate has a downloadable PDF — no "in-progress" placeholders.
Independent Lab Tested
Tested by SGS and Intertek (NB 2649) for CE EN 13162 conformity. Detailed test reports available on request — your engineers can independently verify any spec before approving the product.
Manufacturing Since 2011
Powered by Taishi® — more than a decade of stone wool production, 600,000 tons annual capacity, ISO 9001 / 14001 / 45001 certified. Stenvak is the authorized Taishi distributor for international markets.
Recommended Product Lines
TSCL Industrial Slab
High-density slab format for repeat-volume industrial work — pipework lagging, vessel cladding, mechanical room walls. Same density spec as TSC acoustic board with industrial format pricing.
TSD Multipurpose Board
General-purpose mineral wool board across density and thickness ranges. Versatile for industrial retrofit, equipment housing, and mixed-application sites where one board covers multiple use cases.
Standards & Certifications (Verified)
All certificates listed below are physically on file with downloadable PDFs. None are pending or in-progress.
Industrial Use Cases
Pipework Insulation
Process pipework lagging across operating temperatures supported by EN 13162. High-density slab cut to fit; binder system per Taishi factory spec — request operating temperature data sheet for your fluid temperature range.
Vessels & Storage Tanks
Cylindrical vessel and storage tank cladding. A1 non-combustible per EN 13501-1, hydrophobic surface treatment to resist condensation. Local engineer specifies thickness based on heat-loss calculation.
LNG & Cryogenic Insulation
High-density mineral wool slab for LNG tank and cryogenic pipework insulation. Inorganic A1 non-combustible composition stable across cryogenic-to-elevated service ranges — request the operating temperature and binder stability data sheet for your specific cryogenic service.
Power Plant Boiler & Petrochemical Vessel
Boiler shell, flue, and petrochemical reactor vessel cladding. Hydrophobic surface treatment >98% to resist process moisture; A1 non-combustible per EN 13501-1 and Class A per GB 8624. Local engineer verifies thickness against heat-loss and surface-temperature targets.
Process Equipment Housing
Insulated housings for pumps, compressors, and process equipment. Acoustic absorption performance per EN 13162 acoustic appendix — ask your engineer for SGS/Intertek detailed test reports for noise reduction calculations.
Mechanical Rooms
Mechanical room wall and ceiling insulation. Combines fire protection (A1) with sound transmission control. Local engineer must verify spec match against IBC / IECC requirements based on test reports we provide.
