What is Type IV construction primarily known for?

Type IV construction is primarily known for its use of heavy timber materials. This construction method features solid wood beams and columns that are exposed and are typically used in the building’s framing. The significant aspect of Type IV construction is that it combines the benefits of the durability and strength of timber with a design that allows for larger and more open spaces, often seen in buildings like warehouses and churches.

Heavy timber is recognized for its fire resistance properties; when exposed to fire, the outer layer of the timber will char, which can protect the inner wood from burning too quickly. This characteristic enhances safety in fire situations, making Type IV construction a preferred method where aesthetic and structural integrity are needed along with fire-resistance features.

Understanding the properties and advantages of heavy timber in Type IV construction helps in making informed decisions regarding fire safety, structural design, and compliance with building codes, reinforcing its relevance and application in the field.
