Query
We are proposing a false ceiling of either Gypsum board or calcium silicate board. Please clarify whether these are acceptable under Criterion 17 (GRIHA Version 03).
Solution
As long as a particular manufactured product has recycled content, it is acceptable. However, this has been modified to minimum 5% recycled content in Version 2015 so projects being registered in GRIHA V 2015 will have to follow the minimum 5% mandate. Please refer to the GRIHA Product Catalogue for some examples of products from this category: http://grihaindia.org/#&Product_catalogue
