Modern pre insulated HVAC duct systems tend to include premium performance coupling systems, fabrication methods and a line of accessories to maintain quality HVAC ductwork. A glass wool duct board is used to offer built-in sound absorption and thermal insulation, so it’s not necessary for further insulation it certainly doesn’t need to be added once the duct is fabricated.
Fiber-free insulation core may be used to attenuate the potential risk of loose fibers that approach the air stream in the ductwork, but this significantly improves indoor air quality for occupants in comparison with many existing insulants which in some instances produce loose fibers when connected with the air stream.
Aside from their primary purpose of air conditioning through thermal insulation, these ducts also help boost general energy efficiency.
Options for Pre insulated HVAC Duct
PIR Foam Pre insulated HVAC Duct
This is an excellent alternative to traditional sheet metal ductwork and is good where space and weight are restricted. Galvanized sheet metal ducting requires two steps during installation to ensure vapor seal and thermal insulation no matter what the ductwork but PIR foam air duct provides good performance in addition to lightweight system which requires only one single fix.
With PIR foam ducts savings could be made -up to twenty% reduction on operating costs during 30 years. Accessories and tools needed for fabrication are not hard to be available.
Phenolic Foam Pre insulated HVAC Duct
These panels in this kind of duct may include 20mm thickness phenolic foam insulation that can be faced on either side with 80micron thickness aluminum foil inside, with 200micron galvanized iron on the outside. Other factors including compression strength, thermal conductivity, fire rating, water absorption, dimension change and maximum running temperature are are perfect for personal use, causing phenolic foam ducts a superb replacement for iron sheet ducts.
Expert guidance is necessary for specification and installation, and in addition maintenance and general operation must be monitored at least once the year. A technical service is important for:
Information on ductwork leakage
Heat loss calculations
Condensation calculations
Advice on repairs and modifications, if any
Recommendations for cleaning and desinfecting
Relevant guide on achieving compliance with industry and building standards Info on tax rebates, credits, savings, etc.
Keep The Air Ducts Clean 
In general pre insulated HVAC ducts remain clean for a good length of time and in accordance with the US Environmental Protection Agency, there isn’t any major require to have the operating system taken apart every once in a while for cleaning: However if you have an individual within the household who is prone to allergies, unexplained symptoms or illness, or whether there are clear indications that the ducts are dirty and contaminated, then steps should be taken to contain the ducts cleaned.
