How Does a Pin-Type Moisture Meter Work?

No matter how effectively you work to lay a wood floor, all of your efforts could be for nothing if you don’t consider the floor’s moisture content. Here, we’ll go over why measuring moisture content is important, how pin-type moisture meters work and the best practices for using these types of meters. https://www.delmhorst.com/blog/bid/274196/How-Does-a-Pin-Type-Moisture-Meter-Work

The difference between vapour barrier and air barrier

Moisture problems in walls have been attributed in large measure to two mechanism: vapour diffusion, and now more importantly, air leakage, specifically the deposition of moisture by moist air exfiltrating through the building envelope. While significant technology dated to vapour diffusion control (the vapour barrier) exists (i.e. calculation procedures, regulatory requirements, material standards and performance […]

What is Equilibrium Moisture Content and why is it important?

In many different industries that involve the use of wood or other hygroscopic materials, you might hear the term “EMC” mentioned from time to time. While industry veterans are intimately familiar with this term, to those who are new to the woodworking, flooring, or restoration industries, this term might be unfamiliar. So, what is EMC, […]

The Perfect Wall, Roof, and Slab — Building Science Podcast

Joe Lstiburek talks about enclosure design principles for energy-efficient houses. Insulation, air conditioning, heating, and forced-air delivery systems have all changed the physics of how houses work. Houses didn’t used to rot, but too many of them do now. http://www.greenbuildingadvisor.com/blogs/dept/building-science/perfect-wall-roof-and-slab-building-science-podcast

Vapor Barriers and Wall Design

Good design and practice involve controlling the wetting of building assemblies from both the exterior and interior and different climates require different approaches. Ideally, building assemblies would always be built with dry materials under dry conditions, and would never get wet from imperfect design, poor workmanship or occupants. Unfortunately, these conditions do not exist. Good design […]
