Wood has long been a reliable, sturdy and easy to use building material both for ship-building and home construction. Wood is readily available and centuries of craftsmanship have gone into its use as a modern building material. Wood has a high strength to weight ratio making it resilient to earthquakes and strong for use in small to mid rise structures.

Internal and external cladding is added to the vertical skeletal structure, called studs, to suit the builder’s requirements. Weight from this cladding (drywall internally and siding or other sheathing externally) is evenly distributed among many vertical connections rather than a few large capacity connections. Many components of a structure such as walls and roof trusses can be prefabricated at an alternate location and then brought to the site for more rapid and efficient assembly into the main structure.

Roofing systems are supported by wooden trusses which are usually clad with plywood sheets for rigidity and to support the selected weather-proof surface material for the roof. Roofing surfaces on wood frame structures are usually, but not restricted to, asphalt roofing shingles, cedar shakes (particularly on the west coast of North America), ceramic or brick roofing tiles, and even metal.

Modern construction techniques ensure that adequate ventilation is provided for wood frame constructs after they have been covered so that moisture will not be trapped to potentially damage the skeletal structure of the building through rot or warping.

Use in Building Construction

The use of wood in building construction is prevalent since wood frames are strong, durable, easy to insulate and are cost effective. While wood is an ideal material to build houses and low rise dwellings, wood frames are not suitable for high rise structures. [1]

Concrete is considered a more suitable option primary for its ability to dampen accoustics. Resulting in a much quieter building.

Concrete is also considered to be more durable though it is more expensive. As a result, while wood framed buildings are a cost effective means of construction, they don't hold their value to the same degree as buildings constructed from alternative materials.[2]

When Buildings Fly

The maiden and only flight of the Spruce Goose

Another option for wood construction was made by the Hughes Aircraft Company during WW II. The US War Department issued a contract to produce a large cargo aircraft. Aluminum and other aircraft metals were in short supply, so to conserve metal, H-4 Hercules aircraft would be made mostly of wood. Because of this fact, the aircraft was nicknamed the "Spruce Goose" despite being mostly of birch. To this day, it is still the largest 'flying boat' aircraft ever made sporting a wingspan of 320 feet and 8 Pratt and Whitney Propeller engines. It stood just over 79 feet tall, which is the equivalent of a ten story building. By the way, a US NFL football playing field is 100 yards, or 300 feet, not including the end zones.

Three such aircraft were originally requested but only one was ever built. It made its maiden test flight on November 2, 1947, more than two years after the end of the war. It flew for about one mile and never flew again. It survives in good condition at the Evergreen Aviation Museum in McMinnville, Oregon, USA.
