Week 12

The type of glass which functions based on the climatic conditions is

• Double glazed glass

• Electrochromic glass

• Laminated glass

• Ceramic printed glass

Choose the correct statements related to the use of glass material in the building:

• Lighter structures usually 1/10th of the weight of traditional materials

• High construction cost due to faster envelope

• IS 16231 addresses the use of glass in buildings and the safety related to human impact

• Glass envelope provides better insulation against heat and cold than a concrete facade

State true or false:

Glass envelopes save up to 4-6% of the construction area and, in turn, increase the carpet area.

• True

• False
