Engine installation
Insulation material installed on wood (plywood): 1. Wood (plywood) 2. Flame-proof absorption sheeting. 3. Flame-proof, reflecting soundproofing foil. Above you can see an example of the construction of an insulation material. This type of insulation material is glued to the frame. NOTE! The insulation sheeting faces differently, owing to the type of the material in the frame, i.e. GRP or wood.
Insulation material, being applied on wood (plywood):
Fuel hoses going through a bulkhead should be protected by a grommet where they pass through the bulkhead. The grommet seals off and protects the hose against sharp edges, which might cause leakage. Other cables, electrical wires, battery leads etc can be drawn through a rubber hose or through a special PVC-tube (electrical conduit), built onto the GRP bulkhead of GRP. Any gaps between the tubing and the wires can be sealed off with some kind of insulation material or sealing compound.
Insulation material installed on GRP: 1. GRP 2. Iron-PVC, thickness 2.5 mm (0.1") 3. Flame-proof absorption sheeting 4. Flame-proof, reflecting soundproofing foil
Shift cables, throttle cables and electrical wires coming through bulkheads can preferably be drawn through a tube or a grommet, sealing off properly. At the same time the cables are protected against wear.
