Frequently Asked Questions (FAQ)

A prehung exterior door is a complete unit that includes the door frame and hinges. Slab doors are just the door panel itself, without any frame, hinges, or hardware. Slab doors offer more flexibility for customization but require more effort and precision during installation.

Fiberglass doors offer durability, low maintenance, and sound insulation, and they resist warping, rotting, and denting. Wood doors are a sustainable classic, but they need more maintenance and can be affected by weather over time.

Hinged patio doors, like French doors, swing open either inwards or outwards, requiring clear space for the door arc. They offer a classic, elegant look. 

Sliding patio doors open and close along a track, saving space as they don’t require extra room to swing open, providing a contemporary, streamlined appearance.

The energy efficiency of door materials varies:

  • Fiberglass and steel doors generally offer high energy efficiency, with good insulation properties and tighter seals.
  • Wood doors provide natural insulation, but they can become less efficient if the wood warps over time.
  • Exterior door glass varies in efficiency. To increase energy efficiency, choose double or triple-pane glass with low-emissivity (Low-E) coatings and inert gas fill for better insulation.

To maximize energy efficiency, choose a door with a higher R-value. R-values measure a material’s resistance to heat flow, indicating its insulation effectiveness. The higher the R-value, the better the door insulates, and the more energy efficient it is.
