 COATINGS 
When fiberglass lined ductwork or fiberglass ductboard requires cleaning, Air Duct Cleaners of
Virginia can successfully clean and coat these products providing they are not damaged by
water or delaminating due to age or improper installation. Cleaning is performed using the latest in tools
and technology by our experienced Air System Cleaning Specialist (ASCS).
There continues to be considerable controversy over the use of fiberglass in air conveyance systems. Studies relating to this controversy by manufactuers routinely results in finding that support the use of fiberglass. Studies by independent private or government agencies have often resulted in negative findings. In response to growing consumer concerns, several manufactuers have come up with lines of fiberglass ductboard with improved indoor air quality benefits. These product lines have special surface coatings applied at the factor and require special training for proper installation. 
Weither or not fiberglass in breathing air streams is
ultimately determined good or bad, Air Duct Cleaners of Virginia will "NOT" clean
fiberglass lined sheet metal ductwork or fiberglass ductboard "WITHOUT" sealing
the breathing air stream surface of the fiberglass with a suitable coating specifically
designed for air conveyance systems.
Internally lined sheet metal ductwork is accessed through existing opening or by cutting 8" or 12" round access holes in the sheetmetal in accordance with Sheet Metal and Air Conditioning Contractors' National Assoication SMACNA guidelines to accommodate entry with cleaning and coating tools. When access openings are created at loctions that would be benificial to access in the future, we install DuctMate access doors upon completion of cleaning. 
Fiberglass ductboard is accessed thorough existing opening or by cutting converging 45 degree access holes in
accordance with North American Insulation Manufactuers Assoication (NAIMA) standards. Upon completion of cleaning and coating the facing surfaces of the cutout are sealed with a spray adheasive and reinstalled with foil tape over the access cuts. All coatings used by Air Duct Cleaners of Virginia are specifically designed for air conveyance systems and applied in strict accordance with manufactures instructions. Many companies market other products to coat or seal duct surfaces. Many of these companies apply their coating by spraying them into the operating duct system with a fogger. Tests indicate that materials introduced in this manner tend NOT to effectively coat the interior of the duct surface as advertised. Furthermore, spraying any product into an operating system can potentially contaminate the fan, filtration system, cooling coils, and heating system and negatively effect operational efficiency. 
Air Duct Cleaners of Virginia uses commercial grade airless spray
equipment and high tech spray rods and tips to effectively coat and seal fiberglass surfaces with
coating specifically designed for breathing air systems.
