Features
01
Euroclass A1 fire rating — does not contribute to flame spread or smoke generation.
02
Low thermal conductivity across the full service-temperature range, including high-temperature industrial use.
03
Open fibre structure absorbs airborne sound; ideal for studios, machine rooms, and partition walls.
04
Maintains its shape and insulating value across years of service without slumping.
05
Allows moisture to migrate through the assembly, reducing condensation risk in HVAC ducting.
06
Cuts cleanly with a sharp knife; conforms easily to curved surfaces such as pipes and tanks.

Industry applications
Rockwool lagging on saturated and superheated steam piping reduces heat loss by up to 95% and brings external surface temperatures into safe-touch range.
Insulation around CIP loops, sterilisers, and pasteurisers maintains process temperatures, reduces energy use, and protects operators from burns.
Roof, wall, and partition insulation for commercial buildings, factories, and warehouses across East Africa.
High-density Rockwool maintains boiler skin temperature within HSE-recommended limits and reduces fuel consumption.
Mineral wool absorbs mid- and low-frequency sound, used in recording studios, broadcast booths, and home theatres.

Use case
A Mombasa-based grain processing plant insulated its 12-bar steam distribution network using 100 mm BESS-supplied Rockwool blanket. Surface temperatures dropped from 180 °C to under 45 °C within 48 hours of fitting, reducing personnel-burn risk and cutting boiler fuel consumption by an estimated 11%.
