Duct Wrap Insulation - Thermal Resistance
Thermal resistance to heat flow for faced and unfaced duct wrap insulation:
Insulation Density (lbs/cu.ft) | Insulation Thickness (in) | R-value Installed (h ft2 oF / Btu) | |
---|---|---|---|
Unfaced | Faced | ||
50 | 1 1/2 | 3.6 | |
2 | 4.8 | ||
3 | 7.3 | ||
75 | 1 | 2.6 | 3.8 |
1 1/2 | 3.9 | 5.0 | |
2 | 5.2 | 6.3 | |
3 | 7.8 | 7.5 | |
100 | 1 | 2.8 | |
1 1/2 | 4.2 | ||
2 | 5.6 | ||
150 | 1 | 3.0 | |
1 1/2 | 4.5 |
- 1 h ft2 oF / Btu = 0.18 m2 oC / W
