Noble Composites

January 23, 2002 

Contact Summary: 

Noble Composites currently does not have emission controls. They designed their facility with 

the idea that when the MACT goes final they would already have 100 percent capture. 

They have two spray booths. The gel coat booth is 3 feet high. Gel coat is applied with 

reciprocating spay and this booth is unmanned. The second booth is the lamination booth. This 

booth is 8 feet high and it is manned. The lamination booth is below the 50 ppm OSHA 

requirement for styrene. 

The products are flat recreation vehicle sidewall panels. The sizes are 

40 feet x 106 inches 

50 feet x 106 inches 

40 feet x 120 inches 

The spray booths were designed by Frees.
