I am building a 2 BHK house in Gurgaon. and I want to install modernistic sliding PVC windows from a branded company like Fenesta instead of traditional wooden windows. They are suggesting me to install sliding windows that can be used as doors also for going into the balcony.But the issue is of security. How can we put windows grills in such case? How can we address the security part in such type of cases? Please suggest.
