Buying Guide: Key Considerations For Choosing A Double Door Astragal
- Choose inswing, outswing, or both. Some products are designed specifically for one swing; ensure compatibility with your door’s hinge configuration.
- Aluminum options resist corrosion and are lightweight; satin anodized, black, or white finishes help match door hardware. Consider weather exposure and indoor aesthetics.
- Most products come in 80-inch or 96-inch lengths. Measure door height and space between doors to determine the correct length and whether trimming is needed.
- Some astragals are field-trimmable or field-handed; order with installation instructions in mind. DIY installers should plan for precise cuts and alignment.
- An astragal reinforces gaps between double doors, reduces drafts, and blocks intrusions. For French doors, a flush bolt adds inactive-leaf security.
- Look for tight seals that reduce heat loss, drafts, and noise. This is particularly important for patio or exterior doors.
- Ensure the astragal’s profile and thickness fit your door frames without interfering with hinges or latch hardware.
