While fiberglass insulation is generally safe to handle, it’s important to take precautions to avoid skin irritation or inhalation of small glass fibers. When installing fiberglass insulation, it’s recommended to wear long sleeves, gloves, and a mask.
Reflective Foil Duct Insulation
Reflective foil insulation, also known as radiant barrier insulation, is another option for homeowners. This type of insulation consists of a layer of reflective foil that’s designed to reflect radiant heat, keeping your home cooler in the summer and warmer in the winter.
One of the key advantages of reflective foil insulation is its ability to reduce solar heat gain, which can help to lower cooling costs in hot, sunny climates. However, it’s less effective at reducing conductive heat loss, so it might not be the best choice for colder climates.
Reflective foil insulation is lightweight, easy to install, and resistant to moisture and mold. However, it’s also more expensive than other types of insulation, so it might not be the best choice for budget-conscious homeowners.
Spray Foam Duct Insulation
Spray foam insulation is a type of insulation that’s sprayed into place, where it expands to fill gaps and create a tight seal. This type of insulation is highly effective at preventing both heat transfer and air leakage, making it a great choice for insulating ducts.
Spray foam insulation is typically more expensive than other types of insulation, but it can also be more cost-effective in the long run due to its high R-value (a measure of insulation’s effectiveness) and longevity.
One downside of spray foam insulation is that it must be installed by a professional, adding to the cost. Additionally, it’s important to note that some types of spray foam insulation can emit harmful fumes during installation and for a period of time afterward, so proper ventilation is crucial.
