Does denim insulation burn?

Denim insulation is often treated with a boric acid solution that makes it flame retardant.

Is denim insulation better than fiberglass?

Denim insulation is made from renewable and recycled materials. It is less dangerous to humans and the environment compared to fiberglass. It also has similar R-value and sound absorption capabilities.

What is the r-value of cotton batt insulation?

The R-value of most cotton batt insulation ranges from 13-R to 19-R.

Is denim biodegradable?

Denim is made from natural materials and is biodegradable.

How long does cotton batt insulation last?

Cotton batt insulation can last up to 100 years under suitable conditions.

Do I need a vapor barrier with denim insulation?

A vapor barrier is recommended in humid environments. It is sometimes required under local building codes, especially in mixed and cold climates. It acts as a barrier to moisture in insulated cavities that can result in mold or mildew.

What is cotton batt insulation?

Insulation that is formed from cotton and is manufactured in standard dimensions to fit between attics, walls, and floor joists.

Can cotton be used for insulation?

Cotton insulation is a sustainable alternative to fiberglass insulation.

Is cotton good for insulation?

Cotton has an R-value similar to traditional fiberglass insulation but without the health concerns. It's excellent for soundproofing, made from recycled and renewable materials, and it's safe and easy to install.

Is denim a good insulator?

Denim has many properties that make it a good insulator. It's thermal resistant, absorbs sound well, and is often fire retardant. It’s made from recycled and renewable materials, and it's safe to handle.

Learn about Cotton Batt Insulation

Insulation made from recycled clothing, such as denim jeans, which give these insulation batts their distinctive blue colour. Typically 85% of the content is recycled material. It's made for insulating cavities such as stud walls, attics, and floor joists.

R-value measures the insulating ability of materials. The thicker the insulation, the higher the R-value. Cotton batt typically has an R-value of about 3.5 per inch, so a 2x6 (5 and a half inch) layer gives you R19. Choose the right size and thickness to fit your stud or joist space so that the insulation fits snugly but does not get compressed.

By using waste products, recycled cotton insulation provides a market for recycling and an incentive to keep these materials out of landfill. It also takes less energy to produce than many other forms of insulation. It's formaldehyde-free, uses non-toxic fire retardants, and its insulation value is comparable with fibreglass or cellulose. 'Blue jean' insulation is also very easy to work with yourself and isn't itchy.

In the United States, 13 million tons of clothing are dumped in landfills each year. If that could all be turned into insulation, it would insulate the attics of over 13,000 modest homes per year, to R40 level.
