American Response Vehicles 31 polymeric substance with a minimum R rating of 4. The insulation will be fitted tightly against the structural members to maximize R-value effectively. Gap spacing around each cell within the structure grid and the block foam will not exceed 1/16". A layer of 0.250 inch thick foil encapsulated micro-cellular closed-cell polyethylene with a minimum R rating of 7.75 There will be a minimum air gap of 0.5 inch between the inner most foil surface and the and the ceiling panel. The total R value of the ceiling must be greater than or equal to 11.75. STEPWELL INSULATION PACKAGE: The underside of the curbside step well will be insulated between the structure with urethane froth insulation and then the underside will be undercoated to protect the insulation from weather elements. SOUND DEADENING PACKAGE: The doors, and bare interior walls not covered by cabinetry of the ambulance will be insulated with a premier insulation package that will both offer sound/acoustical and HVAC characteristics for the patient area of the ambulance. The material offers Sound, Air and Moisture barrier by blocks airborne noise from entering the vehicle through open passages. When used between metal surfaces and mounting brackets it acts as a de-coupler and damper reducing the vibration of each surface and minimizing the transfer of noise between the surfaces and the cabin interior. The separation of exterior and interior surfaces by utilizing this product also provides a thermal barrier which enhances the climate control in the vehicle. It is used as a moisture barrier within doors to protect electrical passages and gives a solid feel by filing gaps between panels. The following are some of the characteristics of the material: 1) Is a decoupling / damping layer to reduce impact/airborne noise through floors. 2) Adds insulation value as it exhibits a R value of 3+. 3) Product is made from postindustrial recycled content. 4) Passes FMVSS 302 flammability testing. 5) Passes automotive physical performance specifications. 6) Reduces noise levels up to 75% between the interior and exterior. 7) Is made of Non–PVC so it doesn't deplete the ozone layer. 8) Improves climate control efficiencies. MODULE INSULATION: The module insulation, except the under the floor will consist of material having the following characteristics, 8mm thick nonabsorbent, reflective and will have an air cell core. The air cell core will consist of one layer of polyethylene bubble film that is sandwiched between one (1) layer of 99 percent pure aluminum foil and white colored polyethylene film. The insulation will be installed with at least ½ air space from exterior skins, exposed to direct sun light. The insulation thermal rate testing will be conducted in accordance with A.S.T.M. E84-89A, ANSI 2.5, NFPA 255, UBC 42-1, and U. L. 723. The walls will not be less than R-15.0 down, R-7.31 Horizontally and R5.4 up. The insulation will have a NFPA Class A and a UBC Class 1 fire rating with a flame spread index of 20 and a smoke developed index of 30. The application will include a single layer of the insulation on all four walls, doors, compartments, ceiling, and floor. ADDITIONAL SOUND DEADENING INSULATION: There will be additional sound deadening insulation installed on top of the wheel well liners.
