Techna-Duc® is the PTM PATENTED
pre-manufactured interlocking insulation panel system SOLUTION for exterior ductwork
Techna-Duc® is the shop fabricated exterior duct insulation system that significantly reduces duct air leakage and heating / cooling loss. The aluminum jacketed interlocking panels are made from rigid polyisocyanurate insulation which does not promote the growth of mold or mildew, nor absorbs water.
The polyisocyanurate is laminated in two layers for ease of installation over T.D.C. joint ductwork. The interlocking panels prevent air penetration and intrusion of water or water vapors. Therefore, air quality problems are virtually eliminated.
Techna-Duc® panel sets are numbered per shop drawings for ease of installation. The panels are rigid enough to avoid sagging and withstand weathering. All of these unique features allow PTM to offer a 20 year limited warranty.
Techna-Duc® is fabricated as a four piece-interlocking panel system that equal up to an R-16 @ 2” thickness. The insulation is jacketed with .032” aluminum and sealed with vapor barrier compound. All joints interlock to insure a thermal seal. Techna-Duc® is the solution to bring your rooftop duct up to a beautiful finish that will yield lowest monthly utility costs as well as no maintenance headaches for the lifetime of the installation. On site installation training for the installing contractor ensures all quality standards are being met.
