Top 5 Reasons Pros Choose Rock Wool over Fiberglass Wool

1) IT’S FIRE RESISTANT

Made from stone, rock wool can withstand temperatures up to 2150° F.  This helps to delay the spread of fire in a situation where every second counts. The boiling point of a more common fiberglass insulation can average between 1,000 – 1,300ºF (537.7 – 704.4ºC). The average house fire is about 1100ºF, meaning rock wool can stand up to most dangers within a house fire and give you time to get out. Most insulation will begin to melt at this point making for not only a dangerous situation but allowing the fire to spread more rapidly.

2) IT’S WATER REPELLENT.

Rock wool insulation repels water, so it is not affected.  It is also completely resistant to rot, mildew, mold, and bacterial growth – contributing to a safer indoor environment. Regular Fiberglass will hold water for a long time, slowly collecting at the bottom and causing mildew and rot on the surrounding walls. Rock wool can’t stop a pipe from bursting in the wall, but it can help with what comes after.

3) IT’S MADE FROM STONE.

Rock wool insulation is made from natural stone and recycled material.  Its non-directional fiber structure and high density give it better dimensional stability. This “mineral wool” gives great insulation benefits to a house and makes it more difficult for rodents to just chew through (not without some serious discomfort that is). How do they do this? Well to quote rock wool themselves..

4) IT MAXIMIZES THE COMFORT.

Rock wool installed in exterior walls is a great way to save energy, but there are other applications where it can make a big difference in a home’s comfort. Insulating the exposed concrete walls in basements, above cathedral ceilings and in attics are all effective ways to improve a home’s energy efficiency. Rock wool product helps keep the outside, outside and to keep your home warm in the winter and cool in the summer.

5) IT MAXIMIZES THE PEACE AND QUIET.

Nothing beats the tranquility of a quiet home – and that’s exactly what rock wool provides. Unlike normal insulation, rock wool is an innovative and high-density insulation that’s specifically designed to absorb sound and reduce noise from traveling from one room to another. It traps sound waves and vibrations in the thousands of tiny interconnected spaces created by its unique fiber structure.
