What is the key characteristic of cross-laminated timber (CLT)?
Answer: Alternating perpendicular layers of lumber boards
CLT is an engineered wood panel with alternating layers of lumber boards oriented perpendicular to each other, providing two-way structural strength.
Which standard governs the fire resistance ratings of building assemblies in the US?
Answer: ASTM E119
ASTM E119 is the standard fire test method used to determine the fire resistance ratings of building construction assemblies in the United States.
What is the purpose of flashing in roofing and wall assemblies?
Answer: Directing water away from joints and penetrations
Flashing is a thin impervious material used at joints, transitions, and penetrations to direct water away and prevent infiltration.
In the US, which organization publishes the standard for accessible and usable buildings (ANSI A117.1)?
Answer: ANSI/ICC jointly
ANSI A117.1 is published jointly by ANSI and ICC and provides technical requirements for accessible and usable buildings and facilities.
What is the primary benefit of using insulated concrete forms (ICF) in residential construction?
Answer: High thermal mass combined with continuous insulation
ICF walls combine the thermal mass of concrete with continuous foam insulation, providing excellent energy performance and air tightness.
What is galvanic corrosion and how is it prevented in construction?
Answer: Electrochemical reaction between dissimilar metals; prevented by isolating them
Galvanic corrosion occurs when two dissimilar metals in electrical contact corrode due to electrochemical differences; it is prevented by using isolators or compatible metals.
