Type I (N-1) moisture control units

Posted on January 31, 2017

Q: Why are Type I (N-1) moisture control units no longer available?
-Moisture Unit N-1: Can you Help Investigate the Elusive?

A: Dear MUNCHIE: Prior to 2000, ASTM C-90 included two designations: Type I moisture-controlled units, and Type II non-moisture controlled units. Type I (N-1) units were stipulated to have a maximum moisture content at the time of delivery. In theory, limiting the moisture content of the units reduces dry shrinkage, which...Read More

Concrete Masonry – Use less insulation with thermal mass walls

Posted on January 1, 2017

Q: We’re required by code to have an R value of 26. If I were to use Concrete Masonry cavity wall construction, the wall will be way too thick. Help!      
-Cavities Always Lead to Efficient Buildings 

A: Dear CALEB: A structural Concrete Masonry back up wall with an Architectural CMU veneer is a great choice for resilience, fire resistance, thermal comfort, water penetration, and durability.   An essential component of a cavity wall is, well, the cavity.  The cavity includes a space for ventilation and drainage as well...Read More
