Air Conditioning Glass Wool Insulation: FAQ

EcoIn air conditioning glass wool insulation is engineered for HVAC duct thermal and acoustic performance. Glass wool is an inorganic mineral fiber widely used in air conditioning duct systems worldwide. EcoIn also supplies glass wool board and other glass wool products for HVAC and construction applications.

What is air conditioning glass wool insulation used for?

Air conditioning glass wool insulation is used to thermally and acoustically insulate HVAC duct systems, air handling units, and refrigeration equipment. The flexible roll and semi-rigid slab forms of air conditioning glass wool fit rectangular and circular ducts, reducing heat gain and condensation while improving acoustic performance in commercial and industrial buildings. Air conditioning glass wool is also specified for chiller plant rooms, fan coil units, and cold storage facilities where low thermal conductivity and moisture resistance are required.

What density and thickness does EcoIn air conditioning glass wool offer?

EcoIn supplies air conditioning glass wool insulation at densities from 64 to 96 kg/m³ and thicknesses of 20 to 35 mm. These specifications cover standard HVAC duct liner grades and are available in flexible roll, semi-rigid slab, and rigid board forms. Custom density and thickness combinations are available on request for specific project needs. EcoIn air conditioning glass wool can also be supplied with aluminum foil facing or reinforced foil scrim kraft facing for vapor control in high-humidity HVAC environments.

What fire rating does air conditioning glass wool achieve?

EcoIn air conditioning glass wool achieves a Class A1 non-combustible fire classification per GB 8624-2012. The inorganic glass fiber construction does not sustain combustion and produces no toxic smoke, making it suitable for use in fire-rated HVAC duct assemblies and building mechanical systems where strict fire safety codes apply. Projects requiring air conditioning glass wool tested to ASTM C553 or EN 13162 standards can be accommodated with test reports provided on request.

What are the packaging and delivery terms?

Air conditioning glass wool from EcoIn is packed in plastic film rolls with carton protection for export. Standard delivery time is 7 to 10 days from order confirmation. EcoIn accepts payment via TT, LC, Western Union, Bitcoin, and Trade Assurance, and ships globally with full documentation including packing lists and mill test certificates. Air conditioning glass wool samples are available for laboratory testing and project specification approval before placing bulk orders.

Why source air conditioning glass wool from EcoIn?

EcoIn has supplied air conditioning glass wool insulation to contractors and distributors across Australia, Southeast Asia, the Middle East, and Europe since 2009. Factory-direct pricing, flexible MOQ, and dedicated export documentation support make EcoIn a reliable partner for HVAC insulation projects requiring consistent quality and on-time delivery. Contact EcoIn today for a quotation on air conditioning glass wool with technical data sheets and loading photos included.

How is air conditioning glass wool installed in HVAC ducts?

Air conditioning glass wool is installed by cutting the roll or slab to the required dimensions and adhering it to the duct interior or exterior using mechanical pins or approved duct liner adhesive. When installing air conditioning glass wool as a duct liner, the faced side should face the airstream and all longitudinal joints must be sealed with tape to prevent fiber release. Air conditioning glass wool duct board can also be fabricated into rectangular duct sections using standard sheet metal tools, making it a practical choice for supply and return air systems in commercial HVAC projects that require both thermal and acoustic performance.
