Recycled Blue Jeans To Insulate Your Home

Did you know that you can safely insulate your home with recycled blue jeans? It's true! Blue jean insulation, otherwise known as denim insulation, is an effective, inexpensive and itch-free way to keep your home nice and toasty warm during the colder months (as well as keep in the cool during the summer!). 

The process is slightly more involved that simply stuffing your old blue jeans in between your walls, but installation is very simple and it can be installed easily without gloves. It's eco-friendly, involving no excess waste, and let's face it, blue jean insulation is stylish too!

How Blue Jean Insulation Works:

Cotton Recycled Blue Jean Insulation

Blue jean insulation, as you can imagine, is an insulation material made from recycled and shredded denim (cotton). It literally looks like you've taken your blue jeans and run them through a shredder! It comes in large bales from the hardware store, just like other conventional insulations.

Installation is simple: you just cut the bales into the sizes you need, much like you would with conventional fibreglass. Like any other batt installation, you'll need to be careful to properly set up your building envelopes and fit the installation properly. So do your measurements before you cut!

Some air flow is possible even with proper install, but it's comparable to fibreglass. In fact, blue jean installation has a higher R-value than fibreglass, meaning it is more efficient at maintaining heat. 

Is Blue Jean Insulation 'Green'?

Blue Jean Insulation 'Pros'

Denim insulation is definitely a green alternative. If you're looking for an eco-friendly way to save on heating bills, this is a good place to start.

First off, blue jean insulation is made from recycled fibres. This reduces landfill waste and cotton production. Of course this also saves money because tradition fibreglass insulation is more costly and requires expensive mining practices. Some fibreglass insulation batts are recycled, but not all. Denim blue jean insulation, on the other hand, is 100% post-consumer.

Denim insulation is mostly chemical free, avoiding the formaldehyde and other chemicals used in fibreglass. And it's much healthier for you: there is no possibility of airborne carcinogens like floating fibreglass particles. 

Using blue jean insulation can help qualify you for LEED environmental building certification, if that's what you're going for. 

Disadvantages of Blue Jean Insulation

Blue Jean Insulation 'Cons'

Recycled blue jean insulation, like other cotton insulations, can come with a higher cost of purchase. Installation can be a little bit pricier too, reflecting the increased labor of putting it in place (more cutting, heavier). Blue jean insulation is hard to cut and install properly, so it will take a bit longer. 

You'll still need a proper vapor barrier, and you'll need to ensure that the area is moisture free: water vapor can compromise the ability of denim insulation to stop leaks. If a water leak occurs, blue jean insulation is a bit harder to dry than fibreglass.
