Long before when man understood the importance of roofing, they had a simple thatch from vegetation. Straw, seaweed, clay, earth etc were the materials mainly used for the construction of roofing. Now the most popular are the shingles and tiles, where the roofing material are made more durable, fire resistant, weather friendly etc. With the use of expertise from roofing contractors in Chicago, one can adorn a beautiful roof, above the building.
Centuries before, in many Asian countries bamboo, coconut tree leaves and the bark of certain trees was used. The bamboo was used for the structure of the building and the outer layer. The bamboo stems are split and turned alternatively and placed on the top. The thick bark of certain trees are peeled off and placed on the roof in some places. Even now people living in developing and under developed countries often build a roof above their heads, with simple organic or bio – based materials.
The new roofing materials, which also include synthetic materials, may be of good to the consumers, in the angle of protection and durability, but it may cause environmental hazards. The governments as well as the business professionals are coming out with the green initiation. The world now is completely aware of the seriousness of increased pollution and global warming and hence the demand for organic roofing is also on the rise.
The building and construction authorities in Chicago want to have a greener way to continue their business. On June 6th 2001, a new energy code – Amendment of Title 18 f Municipal Code of Chicago Concerning Energy Efficient Requirements, was passed.
Some of the features included in the new code are:
New requirements for roof, ceiling and wall insulation.
