Polyurethane ducting
 
ADVANTAGES USING POLYURETHANE DUCTING COMPARE TO SHEET METAL DUCTING



1.More safety against fire , fire retardant B1
2.Excellent, constant thermal insulation thanks to the high density Polyurethane (52 +/- 2kg/m)
3.Light Weight. Polyurethane ducting weight 1.46kg/m compared to 9.8kg/m sheet metal duct
4.Silent operation, vibration and reverberation are minimized, increasing system comfort
5.Hygienic and does not absorb humidity
6.Air tight seal, very low air leakage, the leakage test result is only 0.98m/h.m
7.Simple and easy but highly productive fabrication and installation
8.Easy maintenance and modification can be performed on site, cut and gluing can be applied in any section of the ducts.
9.Excellent appearance and long lasting, life expectancy are 20 years.

Funny, I never saw sheetmetal burn.
2.Excellent, constant thermal insulation thanks to the high density Polyurethane (52 +/- 2kg/m)
That's one point.
3.Light Weight. Polyurethane ducting weight 1.46kg/m compared to 9.8kg/m sheet metal duct
Never seen an install that anyone cares what the metal weighs.
4.Silent operation, vibration and reverberation are minimized, increasing system comfort
No better than a lined metal system.
5.Hygienic and does not absorb humidity
Doesn't matter with wrapped duct.
6.Air tight seal, very low air leakage, the leakage test result is only 0.98m/h.m
No better than a properly installed sheetmetal job.
7.Simple and easy but highly productive fabrication and installation
Have to see.
8.Easy maintenance and modification can be performed on site, cut and gluing can be applied in any section of the ducts.
There goes your duct design.
9.Excellent appearance and long lasting, life expectancy
are 20 years.

I have seen many metal jobs 40 plus years old that don't need replacement.



So are you just spamming? Sounds like a sales pitch to me.

Besides, HVAC techs will decide what they install, this is not typically a DIY task.

BTW, I have seen the new ducting, or old, depending on strict definition, and it goes in for under floor (slab) installs here.

joasis, good point. I just hate sales pitches.
