Do you throw your old jeans away when they don't fir anymore? Or when they're damaged and ripped?
A huge amount of clothing, including jeans, ends up in landfills on a daily basis. They end up staying there for years. There is something else you can do with jeans. Denim insulation. This type of insulation is finding its way into buildings. The California Academy of Science used denim for two-thirds of its insulation needs. Another name for denim insulation is natural cotton fibre insulation. It is further made from scraps and clippings of denim clothing. This insulation is suitable for use in both residential and commercial. Construction workers use it in the same places as fiberglass or mineral wool. Carry on reading if you want to learn about its advantages and disadvantages. The most important aspect is how it compares to other types of insulation. Is it worth it?
How Is Denim Insulation Produced?
When you think of denim insulation, you think of recycled jeans, right?
There are also other things that are often added. Denim insulation consists of post-industrial denim and cotton as well. The fabrics shredded are then covered with boric acid. This makes them flame and insect resistant. Denim insulation is available in batts for walls and loose fill for attics. The R-value of denim insulation is 3.5 per inch. Fibreglass can have itchy fibres that can irritate your skin. Denim insulation does not have this effect. But Denim insulation is two times more expensive than fiberglass.
Listed below are some reasons why denim insulation is becoming more popular.
-It is sustainable because it's made out of 85% recycling. The cotton fibres are 100% recyclable.
-It has a higher R-value compared to fiberglass, meaning better thermal performance. And also cheaper energy bills
-Better indoor acoustics. Denim delivers ratings 30% better than other insulation
-Improved health and safety. The insulation does not irritate the skin or the respiratory side
Cons of Denim Insulation
Along with all the benefits explained above, there are some downsides. Here are some examples.
One of the biggest known problems is sizing. Manufacturers claim that batts are standard size. But some people find this sizing isn't accurate. Sometimes they are an inch too wide, sometimes they are an inch too thick.
Because of this, you need to compress the insulation into the cavity. Which results in hampering with its effectiveness.
Manufacturers sometimes compress the batts into rolls for shipping. They might not bounce back to their original thickness.
Denim insulation requires vapour barrier for effectiveness. This extra vapour barrier will cost you more. Alternative products with the same or better R-value cost less. Denim insulation can cost up to three times more than other products.
