Benefit from Reduced Heating and Cooling Loads
If you are looking for more details, kindly visit Langfang Clear Chemical.
The air leakage rate of Kingspan KoolDuct® System ductwork can be a fraction of that of insulated sheet metal ductwork and can easily meet the requirements of SMACNA Class 3. The graph shows the maximum allowable air leakage for each leakage class over a range of pressures from 0.1 to 4 in.w.g. Less air leakage equates to significant energy savings in both fan horsepower and heating and cooling energy.
Saving energy and lowering carbon emissions is what Kingspan is all about. KoolDuct can play a role in your next application having higher, energy saving performance.
Industry Leading Performance
The insulation core of Kingspan KoolDuct® panels has 90% (or greater) closed cell structure, which means that they highly resistant to moisture penetration. In addition, the risk of moisture absorption into the core is effectively eliminated as the factory applied aluminum foil facings provide a high performance and impervious vapor barrier. The panels have a water vapor transmission of 0.34 grains/hr•ft²
Highest R Value to Size Ratio on the Market
The thermal conductivity (k-value) of Kingspan KoolDuct® panels is 0.146 Btu·in/hr·ft²·ºF at 50ºF (ASTM C 518), the lowest of any commonly used insulation material. A low thermal conductivity allows thinner insulation to achieve the required thermal performance. The installed material thermal resistances (R-values) for the range of panel thicknesses are shown in the R value table.
This R-value allows for space saving installations where ductwork can be installed near each other in ways traditional metal ductwork would not be able to be insulated. This includes installing flush to the ceiling where up to 8" of ceiling space can be gained by using Kingspan KoolDuct.

Reduce Installation Costs
Kingspan KoolDuct weighs a fraction of insulated sheet metal; this means cheaper handling, lower transport costs, fewer supports and easier installation. Being pre-insulated, KoolDuct removes the need to wrap the ductwork. With less weight to work with, one worker can do much more and stay fresher throughout the work day.
Installation is familiar to anyone who uses traditional means of ductwork and can be installed by Kingspan and SMACNA standards. Need training for your next application? Contact us or talk to one of our local KoolDuct partners who can assist you.
NFPA 90A Approved 25/50 Flame and Smoke Spread
Kingspan KoolDuct® panels have a resistance to burning and spread of flame far superior to that of rigid polyurethane (PUR) or rigid polyisocyanurate (PIR) insulations. In addition, there is an almost complete absence of smoke when the panels are subjected to a flame source. The insulation core of the panels is thermoset and unlike thermoplastic materials it does not melt, drip or produce flaming droplets. The panels successfully pass the Burning Test (UL 181) and do not exceed flame spread / smoke developed indices 25/50 (ASTM E 84 / UL 723).
Phenolic insulation is a rigid type of insulation with a closed-cell structure, commonly used in construction projects such as ductwork, walls, roofing, and flooring. Due to its design and thermal properties, phenolic insulation is the most thermally efficient insulation commonly used. Phenolic insulation is commonly available in R-values between R-6 up to R-24 in a single sheet of board, but two phenolic insulation boards can be used together to achieve higher R-values such as R-30 to R-45 depending on the thicknesses.
Phenolic insulation is made through a process of utilizing a wet foam mix which is first added to the bottom layer of facing. It then expands to meet the top layer. This is then cooked under pressure and cured in a second oven. When ready, the phenolic insulation boards are cut to the right size and packaged up.
