2. Warm-up: Forum

Unit 2c deals with material properties. Particularly, a development team discusses materials to be used for a new type of roof. In this context, discuss the questions below. Answer at least two of the following questions and respond to at least one contribution of a fellow student.

  1. Which is better: a flat roof or a sloping roof? Why?
  2. What is normally used as a roofing material?
  3. Open your book (Bonamy, D. (2013). Technical English Level 4 Coursebook. Pearson Longman). Find page 14 and look at the three roofs in the pictures. Can you identify these roofs? Match the roofs to these places:
  1. Vancouver Cruise Ship Terminal, Canada.
  2. The Sony Centre, Potsdamer Square, Berlin, Germany.
  3. The O2 Arena, Greenwich Park, London, United Kingdom.

If you are not sure, google the answer.

  1. In what ways is the roofing fabric in the pictures different? What properties must the roofing fabric used have?
  2. What do you think the fabric was originally used for in space?
