Posted December 11, 2018 12:00:22 You might have to spend a lot of time figuring out what type of insulation you need to protect your house from the elements, but a new study shows the best insulation material is probably a natural material, like cotton.
A new report by energy-efficiency experts from the University of Michigan found that the best materials for insulating buildings are those that have a very low energy consumption, such as cotton and wool, as well as natural materials like bamboo.
“Natural materials have very low thermal conductivity, so they are less susceptible to fire, and they’re easier to recycle,” said Matthew H. Muehlhauer, the lead author of the study, which is being published online today in the journal Energy & Environment.
“Natural insulators also have a good moisture content, which helps to minimize mold growth and helps prevent the buildup of debris in the attic.”
The research team looked at the energy-saving properties of five common types of insulators, including wool, cotton, bamboo, and paper, using a variety of measurements to determine the energy efficiency of each.
The study used data from more than 1,500 buildings in the U.S., and included data from all 50 states.
The team analyzed the energy cost of insulating materials for all the materials used in the buildings.
It found that for cotton, for example, the energy costs were lower than those for natural insulators.
For wool, the study found that a typical insulator costs about $0.06 to $0,09 per square foot for a typical attic, compared with $0 to $1 per square feet for natural insulation.
For bamboo, the average energy cost per square meter was $0 for cotton and $0 per square for natural fiber.
For paper, the value was $3.43 for a standard sheet of paper, while a standard piece of paper costs about 2.75 cents per square inch.
The study estimated that for a 10-year lifespan, the savings from the cost savings for natural materials would be worth $5.6 billion.
While natural materials may be cheaper than other insulators to use, the researchers noted that there are a few trade-offs to consider.
For one, natural insulations need to be placed in the loft.
That means they need to stay in place and not move in and out of the room.
That also means that the insulation can be hard to reuse.
There’s also a tradeoff in the durability of natural insulating.
Natural insulating is often made of wood, which has a relatively long life cycle and is more prone to moisture loss than natural fibers.
For the study’s final analysis, the team used a combination of data from a variety, but not all, of the studies.
In the end, the authors concluded that natural materials have a greater energy efficiency than other materials, such that it’s worth buying a natural insulator.
