MinWool-1200 industrial board insulation is made from basalt, a volcanic rock, and bound with a thermosetting resin. Advanced manufacturing technology ensures that our mineral wool products have consistent product quality with high fiber density and low shot content, for excellent performance in thermal control and fire resistance applications.

  • Thermal performance - good thermal conductivity values help minimize and control heat loss, contributing to reduced operating costs and greater energy savings
  • Lightweight, low dust - easy-to-handle and fabricate, these boards are easy-to-cut with a knife
  • Clean handling properties help reduce irritation and minimize job clean up time and expense
  • Low smoke and flame spread - when tested in accordance with ASTM E84, UL 723, CAN/ULC S102, these unfaced insulation boards have a flame spread rating of 5 and a smoke developed rating of 0, the faced insulation has a flame spread rating of 25 and a smoke developed rating of 5
  • Non-combustible - MinWool-1200 industrial board is rated as non-combustible in accordance with ASTM E136 and CAN4-S114-M
  • Mold resistant - MinWool-1200 industrial board does not support growth of fungi
