Plastics

Materials other than reinforced con­crete are also being widely used in modern construction for prefabrication. The plastics that were unknown only a few decades ago have become extremely important and wide­ly used for construction purposes. The plas­tics being used nowadays possess many ad­vantages. First of all they are extremely light and their tensile strength is greater than that of many metals. Besides, they are weather-resistant and resistant to attacks by industrial fumes and to a great number of chemical sub­stances. Some of the examples of the con­structive use of plastic materials have been domes housing radar antennae and electron­ic equipment. Such domes built in America and Canada are as high as 116 feet.

The panels of the domes are made of polystyrene and polyurethane foam and are protected by glass cloth cemented to the fume panels with epoxy resin. Some other dome structures are made from panels of thin sheets of reinforced fibreglass. Up till that time fibre-glass was familiar as a roofing material. Now it is becoming more and more popular in the manufacture of panels. The methods by which plastic shapes are produced has led4o a new approach to constructional and architectural forms.

7. Canada. "Habitat"

Multiple housing known as "Habitat" may serve as an example of unfamiliar forms of design. These new forms may be said to have the most stimulating effect on the de­velopment of construction and architecture. They provide the answer to problems that are still unsolved.
