I have decided to review variable doors and windows which are available in Indian market to share my opinion about the product based on my hand-on experience & information available to general public. The purpose of reviewing different products to educate people about quality & limitations in system.
Let us start with tostem which is part of lixil group from Japan. Here one of the customer of tostem invited me to visit their home. They were using 14 mm laminated glass in all Slide doors. 14 mm laminated glass comprises of following specifications -6mm clear toughened + 1.52 mm clear PVB + 6mm clear toughened. This particular glass gives security class P3A - P4A as per protection class of EN standards.

In the nut shell, single point locking with security glass does not make a product premium. I am sure tostem also has some good products but this one should be avoidable where security is a concern.
