Why is heavy timber fire resistant?
This is because the build-up of carbon on the surface will limit the oxygen supply to the wood below and act as insulator. Therefore, the wood below the charred level will be cool and retain 85 to 90 per cent of its structural integrity.Sep 10, 2015

What is heavy lumber?
Solid-sawn heavy timber members are predominantly employed as the main structural elements in post and beam construction. The term 'heavy timber' is used to describe solid sawn lumber which is 140 mm (5-1/2 in) or more in its smallest cross-sectional dimension.
What factors dictate the use of heavy timber over economic factors?

Which of the following is a reason that a heavy timber building is a conflagration breeder?
All of the following are reasons that a heavy timber building is a conflagration breeder, except: Tremendous amounts of heat transfer from convection currents, which can ignite exposures hundreds of feet away. Which area in a heavy timber building may be an area of refuge during a collapse?
Is heavy timber considered non combustible?
Code Text: Type IV construction (Heavy Timber, HT) is that type of construction in which the exte- rior walls are of noncombustible materials and the interior building elements are of solid wood, laminated wood, heavy timber (HT) or structural composite lumber (SCL) without concealed spaces.
What is mass timber?
Mass timber refers to a system using one or more of a few structural materials—glued-laminated timber (glulam), cross-laminated timber (CLT), or nail-laminated timber (NLT). Glulam has been used in the United States for more than 80 years and is very common. CLT is a large, prefabricated member made up of layers of framing-lumber laminated ...
What is CLT in construction?
CLT is a large, prefabricated member made up of layers of framing-lumber laminated perpendicular to one another on their wide faces. This technique has been around for decades in Europe, and is now gaining traction in the United States. An alternate to CLT, NLT is fabricated in-place using framing-lumber and nails.
