Flexi Duct R6 and R8: All you need to know

If your home is equipped with a cooling, air conditioning HVAC system, a ductwork system is used to circulate warm or cooled air all through the house. 

The distribution method for circulating warm or cooling air in a property is ductwork. Even though sheet metal is the most common material for ducting, most of it is insulated within residential installations.  R-value is a metric used to determine insulation. Heat resistance is measured in “R” units. The bigger the value, the greater efficient the insulation, so to speak. The R6 and R8 ducting systems are two instances. In addition, we’ll contrast R6 and R8 ducting and go through their benefits and drawbacks.

Material Thickness

Among the most obvious distinctions between R6 and R8 ductwork is really the thickness of the ductwork materials used to construct them. Insulation is stronger in R8 ductwork than it is in R6 ductwork. This indicates that utilizing R8 ducting for air – conditioning system installation will provide excellent insulation instead of using R6 ducting.

Climate Considerations

There are a few key factors to consider when selecting the ideal R-value ducting for your house. Climate would be first. You need at least R8 ducting if your home is situated in a cold region. It may possibly reach a height of R11 in the attic area. Homes in warmer and varied climates can utilize ducting with a lower R-value, although R6 or R8 is still typically recommended.

Heat Insulation Efficiency 

When it comes to heat insulation, R8 ductwork is more effective than R6 ductwork. Power loss is reduced by R8 ducting by roughly 2%. Therefore, 3 percent less power is used. Thus, if your property has R8 ductwork, your power expenditures will be reduced.

Costing Differences

R6 ductwork is less costly in terms of expenses. R8 ductwork will cost extra since its diameter is bigger. You may need to pay significantly more for R8 ductwork if your house is big. R6 ductwork is more versatile and can fit within smaller locations than R8 ductwork due to its lower external size.

It might not be feasible to switch from R6 to R8 at a later stage. Due to the difference in dimension and the R8 ducting’s thickness, it could not function properly. That may lead to problems such as ducting that is noisy.

Both the R6 and R8 ducting systems have their own unique purposes and specialties that suit specific environments and spaces. The decision for choosing the appropriate ducting system for your space depends upon your requirements.
