<p>A system for cutting insulation board to size. Insulation board is often cut by the use of a hand saw, creating large amounts of dust and debris. The present system aims to mitigate the creation of such debris through the use of a guided knife blade. The system comprises a frame device 1 into which boarding 16 is inserted and held for cutting. The frame may comprise parallel upper battens 2, 4 hinged 10 to end section 5, the battens defining a cutting guide 15, 14 in which a cutting tool 11 may be located. The cutting tool may comprise guide pieces 12, 13 to further seat the tool in the cutting guide. Screw-down holding points 18 may be provided in the parallel upper battens to enable different depths of board to be held whilst cutting.</p> |
