net zero | passive house, maryland: mineral wool foundation insulation + waterproofing

September 25, 2014

The Roxul Rockboard 80 mineral wool has made its installation appearance on site.  It has even been deemed “fantastic” to work with by our contractor, Jeff Gosnell of Gosnell Builders! We would like to thank the team at Roxul for their endless hours in ensuring the appropriate foundation application of their product.
The lovely turquoise product is our Rub R Wall waterproofing, a 100% rubber, asphalt-free waterproofing membrane.
