Many commercial ducts cleaning contractors experience fiberglass insulation airborne handlers, plenums, and also ductwork of the heating and cooling systems they are cleaning. Engineers originally made fiberglass insulation in a/c systems for acoustical reasons (assistance control audio) or for a thermal reasons (to help protect against temperature level loss). Dealing with fiberglass insulation can be a genuine difficulty. It can be harmed or deteriorated by:
– Air disintegration from the follower airborne trainer
– Smoke contamination from a fire
– Mold or microbial contamination brought on by the mix of excessive wetness as well as a microbial food source (dust).
What do you do? What are your options? In all cases, the first thing you must do is to inspect the fiberglass to establish the problem it remains in. Can it withstand the roughness of cleansing or does it break down when you touch it? Is it wet?
In air managers and large plenums/ductwork that you can creep, you have the adhering choices to think about:
– If the fiberglass insulation remains in good shape as well as can stand up to the roughness of cleaning you can clean the insulation or clean and also coat the insulation.
– If the fiberglass insulation is not healthy and also can not withstand the rigor of cleansing you can get rid of the insulation or remove and also layer the sheet steel or remove and replace with brand-new insulation or eliminate and change with the brand-new layered product or remove and change with a close cell product.
– If the insulation is wet you can remove the insulation or remove and also layer the sheet steel or remove and replace with brand-new insulation or eliminate and replace with new covered insulation or eliminate and also change with a close cell product.
In ductwork that is too small to crawl, you have the complying with alternatives to consider:
– If the insulation is in good condition as well as can withstand the rigor of cleansing you can clean up the insulation or clean and coat the insulation.
– If the insulation is not healthy and also can not stand up to the roughness of cleansing you can remove the ductwork and replace it with new ductwork (with insulation outside).
– If the insulation is wet you can get rid of the ductwork and change it with new ductwork (with insulation outside).
Regular cleansing techniques include contact vacuuming or cleaning with a powered brushing system/robotic system with a nylon brush and then air cleaning. This gets rid of the dirt/contamination from the surface area of the insulation yet does not get rid of the dirt/contamination from the interior of the fiberglass insulation. To maintain this dirt/contamination in the inside of the fiberglass insulation from coming to be a future issue you can layer the mechanical insulation. The benefits of layer consist of:
– Securing down any type of continuing to be loose fiberglass fibers after cleaning.
– Locking in the dirt/microbial spores/smoke contaminates the interior of the fiberglass so we can not smell the smoke particulate as well as the microbial spores can’t integrate with moisture and expand.
– Offering an extra durable air-heavy steam surface area that is more immune to air disintegration and moisture and also is easier to clean in the future.
– A way to prolong the life of the a/c system for the building proprietor at a lower cost than changing ductwork, air trainers, and various other system components.
One more alternative to cleansing, as well as finishing, is to replace the damaged/degraded mechanical insulation with closed-cell insulation. You remove the existing insulation; procedure and cut the suitable size close cell material; after that adhesive and also rivet the close cell insulation in place; seal all exposed sides as well as butt joints. The advantages of relining with shut cell include:
– You have eliminated the harmed fiberglass insulation altogether.
– Supplying an extra resilient air steam surface area that is a lot more resistant to air disintegration and dampness as well as is much easier to clean up in the future.
– A way to expand the life of the HVAC system for the structure proprietor at a lower expense than changing ductwork, air handlers, and also various other system elements.
