Go Cheap Look: No Interior Roof Cladding of BIA

The above is another photo of the roof section above the immigration check area at the Beijing International airport. You can see the branch formed column that support the roof trusses at various points of the roof. There is no roof cladding applied like what you see at the KLIA (Kuala Lumpur International Airport) – see the previous blog post. The lack of roof cladding exposes the metal roof sheets which makes it look cheap like the kind of construction you see in general warehouses. In tropical countries, having no insulation of the roof like that in between the external roof material (especially metal or zinc) & the roof interior cladding will result in rising temperatures inside a building & increase cooling costs. In Beijing, however, the weather is rather cool hence they can get away with no interior roof cladding & ultimately lowering building costs.
