Fiberglass entry doors are very airtight and energy efficient. Fiberglass doors often come insulated, which provides an additional energy saving advantage over wood doors. They offer up to five times the insulating ability of wooden doors.
If the rollers holding the sliding door jump out of the track, the whole door will move out of alignment. This will make it impossible to open or close it until the problem is fixed. A common reason for this is the screws holding the rollers against the track. They can become loose or fall out over time. In such cases, homeowners will need to screw them back in or replace the missing ones. Also consider spraying some lubricant on the rollers to help them move more easily.
