Change in dimension a porous tile may undergo as a result of moisture absorption, analogous to change produced by temperature increase.
Moisture proofing
Application of an asphalt content barrier on the outside wall of a basement so that water is not absorbed into the concrete.
Moisture relief vent
A vent installed through the roofing membrane to relieve moisture vapor pressure that has been trapped within the roofing system.
Moisture resistant panels
Dry wall panels, also known as water-resistant panels or greenboard, which have water-resistant compounds added to the gypsum core and covered with water resistant paper so they are usable in areas such a bathrooms, where moisture is present. Fiberglass mesh tape is just on the joints and then they are sealed with water-resistant joint compound.
Moisture scan
A survey of a roof specifically to detect the amount of moisture present in the roof system. Devices used in moisture surveys can be capacitance meters, infrared cameras, and nuclear scanners. Infrared scans can be done from the air or on the surface of the roof. Capacitance and nuclear scans are done on the roof surface. It is argued that the most accurate scans are done from the surface of the roof with the most accurate of these being nuclear scans.
Moisture vapor transmission
Using perms to measure the amount of water vapor able to pass through a material. Perm = one grain of water vapor per square foot, per hour, per inch of mercury pressure differential (0.491 psid).
Mold
(1) To form, make or shape. (2) A pattern or hollow form used to give a certain shape to something that is poured into it in a molten state. (3) Furry growth on a surface caused by fungi in the presence of decay or dampness.
Moldboard
Wood used to make concrete forms.
Molding
A strip of decorative material having a plane or curved narrow surface prepared for ornamental application. These strips are often used to hide gaps at wall junctures.
Molding cutter or head
Rotary cutters, which attach to a table saw or radial arm saw, to shape molding by moving the material past the rotating molding head. The fence can be set to the size of the material and the depth of the cut can be adjusted.
