Buying Guide: Key Purchase Considerations
- Door material and insulation: Look for polyurethane foam core and fiberglass skins for durability, weather resistance, and energy efficiency. Avoid wood when you need lower maintenance in harsher climates.
- Door configuration: Decide on right-hand vs left-hand inswing and whether you want one or two sidelights. Sidelights affect opening width and light entry.
- Glass type: Hammered glass offers privacy and style; Low-E glass improves energy performance by reducing heat transfer and UV exposure.
- Install considerations: Knock-down designs require on-site assembly. Ensure rough opening dimensions match the door’s unit size and jamb width for a proper fit.
- Frame and trim: A full-body vinyl jamb and brickmould provide moisture resistance and a clean finish. Check whether LVL stiles are used for added strength.
- Maintenance and finish: Through-color fiberglass skins resist fading and scratches better than painted surfaces. Consider color stability in your climate.
