In this video, Matt Hoots of Sawhorse, Inc. and Chris Laumer-Giddens of LG Squared, Inc. share why they think highly of ROCKWOOL stone wool insulation, also known as mineral wool insulation. 


Top areas of strength include sound, fire, and thermal protection, as well as less air infiltration due to the cross fibers.  The two discuss some benefits and risks of other materials, while acknowledging that no material is perfect.  Chris notes that spray foam is associated with health risks, and the installs are trickier.  Foam and plastic products tend to transfer noise more, and they expand and shrink more. Ease of install is mentioned as an additional ROCKWOOL benefit. Stone wool also tends to hold its form, even over 60 years or more as an example shows. 


Another stone wool benefit is that stone wool helps prevent bugs, as they can’t eat or or burrow through the material.  


Stone wool insulation also holds up over time. It doesn’t dry out, and holds its r value over time, and also as temperatures rise and decrease.  


As Matt puts it, he tends to favor building materials that “solve problems without creating new problems.” For a personal project, sound and bugs both influenced Matt’s choice to use ROCKWOOL. He had already noted that rigid foam on his house had some percussive effects, where his family was hearing neighing noise, or worried their own noise would affect them or their neighbors more.  


Looking over the long term, Chris notes that ROCKWOOL maintains its rigidity, form, function and efficiency.  As the two discuss, these benefits add up and make stone wool a solid choice.
