2020-10-14 · Axios reporter Bryan Walsh highlights how MIT researchers have developed a new solar-powered device that can extract drinkable water from the air and “could help alleviate water scarcity in some of the world's driest regions.” Walsh notes that the new design “makes use of a more common material called zeolite, doubling its capacity to generate water.”


As in the water barrier there is a prescriptive approach to air barriers. The following list reveals 15 materials that are acceptable for use as an air barrier: 1. Plywood with a thickness of not less than 3/8 inch (10 mm). 2. Oriented strand board having a thickness of not less than 3/8 inch (10 mm). 3.

Water resistant barriers serve as a second line of defense against moisture (in its liquid state) entering the building. The International Building Code, IBC, has specific language that requires the use of these barriers. In section 1403.2 in the 2012 IBC code, it calls for a “weather-resistant” exterior envelope.


A vapor barrier is designed to restrict the flow of water vapor through a material, just the same as an air barrier material restricts the flow of air through a material. Remember that air leakage – and not vapor diffusion – is the real concern because air leakage accounts for over 200 times the amount of moisture transmitted by diffusion.

Most commercially available polymeric-based water-resistive barriers are highly moisture-resistant and therefore, do not absorb water like typical Grade D or felt building papers. Polymeric water-resistive barrier are typically stronger than Grade D or felt building papers, thus they tend to have better durability than conventional building papers.
