rockwool vs fiberglass health

Share with:


Although they are both excellent insulators there are a few differences which explains why mineral wool is becoming more prominent nowadays. The boiling point of a more common fiberglass insulation can average between 1,000 – 1,300ºF (537.7 – 704.4ºC). I made this video to help prevent others from making the same mistake that I did. But the lessons can be applied to any building, the most important being that health matters as much as R-Value. This did not proceed to the next level, “known carcinogen,” and in 2011, following more research, it They say "solid petrochemicals are a lesser of two evils when compared to CO2" and deride my concerns as "an example of 'Perfect is the enemy of good'.".

Bynam, Jr., Insulation Handbook (New York McGraw-Hill, 2001), p.78. Mineral wool is a stone-based mineral fiber insulation comprised of Basalt rock and recycled steel slag. The amount of recycled content is optimized to provide the ideal thermal, acoustic, and fire protection properties from ROCKWOOL products, while still maximizing the recycled content. In the meantime, check out this awesome video showing the comparative fire resistance between ROCKWOOL and a more standard glass fiber insulation. Fire resistant. ROCKWOOL products contain between 16% or 40% pre-consumer recycled material dependent on the ROCKWOOL manufacturing facility location. As an example, the R-15 mineral wool costs about 80¢ per sq.

Researchers are looking into fiberglass and how the material can penetrate the lungs and cause numerous health issues. In 1984, fiberglass was classified as a “reasonably anticipated” carcinogen. The average house fire is about 1100ºF, meaning ROCKWOOL can stand up to most dangers within a house fire and give you time to get out.

Rockwool can withstand temperatures of up to 1000° C (1800° F), while fiberglass melts around 600° C (1100° F). Earthwool is designed to be easier to handle with its itch-free properties. The newer forms of rockwool pose little risk of breathing it in. It also has a bad reputation because of really terrible installations. Whereas rockwool fibers are spun from liquid rock, fiberglass is spun from liquid glass and glued together with a resin. It is also completely resistant to rot, mildew, mold, and bacterial growth – contributing to a safer indoor environment.

(The old ROXUL branding is still there, but the product is the same great ROCKWOOL we know and love! Both HTs had (have) staggered studs. Its non-directional fiber structure and high density give it better dimensional stability. Even though Fiberglass does not harm the environment as Rockwool, it can still be as hazardous as the latter. Many contractors and homeowners insist on ROCKWOOL® residential insulation products for the advantages it offers over a conventional insulation like fiberglass. In many ways, mineral wool is a superior insulation product. When you are up against the American Chemistry Council, Formaldehyde Facts, and this gem from the Kitchen Cabinet Manufacturers Association, it is hard to know what to believe.

It traps sound waves and vibrations in the thousands of tiny interconnected spaces created by its unique fiber structure. Irritation and Redness According to the website for the Agency for Toxic Substances and Disease Registry, skin exposure to rockwool can cause acute irritation of the skin, eyes and the upper respiratory tract which causes difficulty breathing and can lead to … This document is a great place to start.

Rock wool and fibreglass insulation provide thermal barriers to minimise heat loss in walls, ceiling, floors and attics. Mineral Wool: How They Stack Up R-Value: The thermal resistance of insulation is measured by what’s commonly known as the R-value, and the higher the R-value, the better. It contains 70% recycled material, making it a greener product than fiberglass at 20-30% recycled material. That’s pretty cool! What was really surprising to me was that fibreglass came next; I always thought it should be avoided. They also include relative costs.
