There are several options when choosing a glazed door. For maximum light, consider a door with a large glass area. For privacy and security, opt for one or two small sections of glass, or glazing that is decorative and obscures the view into your house. If there is a possibility of ultraviolet (UV) damage to floors, rugs and furniture, consider choosing a glazing that resists UV rays.
There’s a solution for dealing with wood screws which have broken off below the surface of the wood. If you don’t want to risk damaging the wood by digging it out, try driving the screw deeper into the wood with a nail set. Then just fill the hole with a wood filler, and drive a new screw next to the broken one.
