2. Design Solution For a 35kW level II enclosure: 11 pieces are to be cut from received board Installed into walls/doors Installed above generator and around exhaust system

3. Insulation board dimensions

4. Cutting/Forming Done with circular saws 57.5 feet of cutting per enclosure Ventilation is required to eliminate spread of dust

5. Insulation of door panels

6. Insulation of exhaust area

7. Elimination of perforated steel

8. Exhaust box installation Insulation block Perforated steel Small bolts

9. Thickness will remain the same Thermal conductivity of expanded perlite:.85 Btu in/hr ft 2 °F Thermal conductivity of mineral wool: 1.06 Btu in/hr ft 2 °F Same thickness will be used Thermal insulation will improve

10. Thermal conductivity heat flow ratethickness thermal conductivity area *Assuming a heat flow of 3000 Btu/hr ∆T = 735 °F For mineral wool with k = 1.06 Btu in/hr ft 2 °F ∆T = 590 °F

11. Further Testing Acoustical testing  Mock-up enclosure Mechanical testing  Ability for material to withstand vibrations  Impact testing
