Hi there, just wondering if there’s anyone who does double layer security door at the back of their house instead of single layer for security purpose? I’m also aware theft can also happen from roof and unlocked windows. Greatly appreciate any advices on this.

Install double if you feel unsafe

are you going to enter the house from rear door? if not.. just get a custom metal door with no handles or keyholes from external. people doing your grille should be able to do it.
