The panel duct or pre-insulated aluminum duct has been in the world market for almost fifty years, but until recently the construction of rigid ducts for air conditioning was mainly directed to fiberglass and galvanized iron sheet, it can be said that in the last decade the pre-insulated aluminum duct has replaced almost one hundred percent of these materials and in this article we will see why.
The duct panel has a rigid polyisocyurate (expanded polyurethane) foam core with a thickness between 20mm and 40mm, covered on both sides with a stamped or embossed aluminum foil between 0.06mm (60 microns) and 0.20mm (200 microns) and are mainly used in the manufacture of ducts for industrial air conditioning and / or ventilation systems with low and medium static pressure characteristics.
Panel duct (1.1 kg / m2) is up to 60% lighter than fiberglass (1.8 kg / m2) and up to 400% lighter than 24 gauge HG sheet (4.8 kg / m2).
The embossed aluminum coating prevents air contact with the internal insulation, preventing the detachment of particulate material and moisture absorption, which happens with fiberglass. Aluminum prevents the accumulation of dust and other particles, maintaining hygiene in the air, preventing people's health and avoiding bacterial and microbial proliferation, ensuring indoor air quality.
Due to the low density of the rigid foam, approximately 35 Kg / m3 has excellent thermal properties preventing heat transmission, as well as its high degree of pneumatic tightness 8 times greater than that of traditional ducts, there being no possibility of leakage of air or thermal bridges, avoiding condensation along the length and width of the duct, all this translates into a reduction in energy consumption by up to 25%.
It is a product free of CFC and HCFC, the materials and waste produced during the manufacturing process are inert waste, aluminum is a non-heavy metal) and a thermoset plastic.
The panel duct is economical, easy to transport, manufacture and install, it requires little investment in high productivity and easy-to-use hand tools, one of its greatest advantages, unlike other materials, is that, for the development of more specialized jobs , it has a whole series of accessories, showing that it is not just another material, but an all-in-one system.
The panel duct is highly safe against fire because it is non-flammable, it has countless certifications in this regard; Unlike fiberglass, although it is not flammable, the compounds and solvents with which the sheet is manufactured, if they are, also the smoke emanated is toxic.
The panel duct can be installed indoors or outdoors in urban and industrial centers, residences, hospitals, offices, cinemas, theaters, hotels, shopping centers, supermarkets, food or pharmaceutical industries, or in any other type of installation.
In conclusion, the benefits of the panel duct are:
- Easy to design, estimate, manufacture and install
- The facilities are always well proportioned and pleasing to the eye
- Can be installed practically anywhere indoors or outdoors
- It is a very safe material, it is risk-free
- Energy Savings
- Hygienic and healthy
- Silent operation
- Low Maintenance
