Acoustic Insulation is used to reduce unwanted noise. In automobiles, acoustic insulation can be found in door panels, headliners, instrument panels, even under hood applications. There are a variety of materials used to reduce engine or exhaust noise and to reduce the amount of exterior noise entering the cabin. Depending on the specific application, acoustic insulation can be attained by using one or a combination of:
- Polyester Fiber (PET)
- Polypropylene Fiber
- Fiberglass
- Urethane Foam
- Shoddy Cotton
Often times the acoustic performance of these products can be improved by adding a foil or scrim facing to the material. Derby Fabricating has developed close working relationships with multiple insulation manufacturers. We also have the ability to laminate pressure sensitive adhesive to any of these insulation materials up to 60” wide, and can die cut parts as large as 76” x 72”.
Duct insulation is sometimes required in overhead air conditioning ductwork. We provide foam wraps that are used as acoustical insulation and to prevent and/or absorb any condensation that may form on the duct. Excess condensation can drip onto the headliner and potentially stain. Derby has the ability to take 3 dimensional CAD data and provide die cut parts to wrap the component.
Engine cover insulation is used to reduce both engine noise and temperature to the surface of the cover. Derby can provide insulation components made with a high melting temperature lofted polyester fiber. This product is an excellent candidate for ultra sonic welding and heat staking.
Headliner Insulation is used to reduce unwanted noise. There are a variety of materials used to reduce the amount of exterior noise entering the cabin. Depending on the specific application, acoustic insulation can be attained by using one or a combination of:
- Polyester Fiber (PET)
- Polypropylene Fiber
- Fiberglass
- Shoddy Cotton
- Urethane Foam
