Mineral Wool Insulation
The workhorse of industrial insulation - spun rock fibre that holds heat, absorbs sound and does not burn, supplied as wire-mesh blankets, slabs, pipe sections and loose wool.
Mineral wool is spun from molten rock into a mat of fine, interlocking fibres. That structure does three jobs at once - it traps heat, it absorbs sound and it will not burn - which is why it is the most widely specified insulation on industrial plant in the Gulf, from boiler houses and process piping to plant rooms and acoustic enclosures.
We supply it in every form the site needs, from wire-mesh blanket for vessels and ducting down to loose wool for packing, and we can put the jacketing, banding and vapour barrier on the same delivery.
Why engineers specify it
- Continuous service up to 750 °C, with fibres that do not melt below 1000 °C
- Non-combustible: Euroclass A1 to EN 13501-1
- Thermal and acoustic performance from one material
- Resilient - it recovers its thickness after handling, transport and vibration
- Water-repellent, chemically inert and low in chlorides
- High compressive strength in the upper densities, for load-bearing and trafficked areas
- Rot-proof and dimensionally stable for the life of the plant
- Cuts with a knife and wraps to shape on site, with no special tools
Supplied as
| Form | Thickness | Density |
|---|---|---|
| Blankets with GI or SS wire mesh | 30-100 mm | 40-128 kg/m³ |
| Slabs and blocks, faced or unfaced | 25-100 mm | 30-140 kg/m³ |
| Pipe sections, faced or unfaced | 25-100 mm | 50-160 kg/m³ |
| Loose wool | - | Supplied by weight |
Pipe sections cover 0.5" to 24" nominal bore. Facings are available as aluminium foil, FSK or glass tissue, and blankets can be stitched to galvanised or stainless mesh depending on the service temperature.
Thermal conductivity
| Mean temperature | W/m·K |
|---|---|
| 50 °C | 0.039 |
| 100 °C | 0.045 |
| 200 °C | 0.060 |
| 300 °C | 0.082 |
| 400 °C | 0.112 |
Typical values for a 100 kg/m³ product. Conductivity moves with density, so ask us for the data sheet of the grade you are specifying.
Where it is used
- Boilers, steam lines and hot-water piping
- Vessels, tanks and ducting in refineries and petrochemical plant
- Power generation and district cooling plant rooms
- HVAC ductwork, where the same slab does the thermal and the acoustic job
- Acoustic enclosures, partitions and fire-stopping
- Marine and offshore installations
