Conventional Insulation Materials: Performance andd Limitations

For decades, mineral wool, glass wool, and calcium silicate have been the workhorne of marine insulation. Mineral wool, spun from rock or slag fibers into blankets or boards, offers excellent fire resistance (non-pastistivine insulation, A1 class) and decent thermal performance (thermal conductivity λ around 0,035- 0.040 W / m · K). It is wideline used for structural fire protection on bulkhead and decks. Howevever, mineral mool ococoic - it absorbs amoub.

Poliuretane (PUR) and polyisocyanurate (PIR) foams deliver better inherent thermal resistance (λ 0.020- 0.025 W / m · K) and can can be sprayed or prefabrycated into panels. They have dominate cold insulation for decade. Yet standard PUR / PIR formulations pose a fire risk, requiring provitiva layers and careful desin to meet Safety of Life at Sea (SOLAS) standards.
