Product Description
Lancaster Mineral Fibre Galvanised Lagging Mattress comprises unbonded mineral fibres securely stitched to galvanised hexagonal wire mesh to form a mattress with excellent thermal insulation properties, making this product ideal for external insulation lagging and cladding applications in construction projects.
The unbonded nature of the product means that no charring, off-gassing or embrittlement occurs due to degradation of organic binder, making the mattress especially suitable for external insulating of hot industrial plant.
Advantages
Durable – Safe – Cost effective
Chemical Composition
Lancaster Mineral Fibre Galvanised Lagging Mattress is manufactured from basaltic material, incorporating an addition of recycled fibres into the melt. An inherently low level of mineralogical calcite (CaCO3) is maintained, which gives the product very good resistance to attack by acidic residues. Oxide composition is given below:
| Silicon oxide (SiO₂) |
43–50% |
| Aluminium oxide (Al₂O₃) |
11–18% |
| Iron oxide (Fe₂O₃) |
10–15% |
| Calcium oxide (CaO) |
10–14% |
| Magnesium oxide (MgO) |
8–14% |
| Sodium oxide (Na₂O) |
2–5% |
| Potassium oxide (K₂O) |
0.5–3% |
| Titanium oxide (TiO₂) |
2–4.5% |
| Residual mineralogy as CaCO₃ |
0–0.05% |
