Lighter and more energy-efficient than concrete buildings, wooden skyscrapers are a durable and cheaper solution to current construction models in cities with high population densities. Vertically designed, these urban towers employ cross-laminated fiber or veneer lumber instead of concrete or old-growth wood to accommodate housing projects or mixed-use buildings.
Structurally, wooden high-rise buildings are constructed with perpendicular strips of wood glued together, forming sturdy beams. Such massive beams and columns become possible due to aggregation processes of smaller wood pieces. These materials resemble the characteristics of old-growth wood in strength and resistance. The elements composing these buildings can be prefabricated in factories. Also, construction with timber can be modular and adaptable to variable weather conditions.
In terms of fire-resistance, the timber panels used to make such structures should be dense enough to ensure that they do not catch fire easily. Another option to protect these buildings from fire is to cover them with fire-proof gypsum boards.
