Buying Guide: Key Purchase Considerations
Material and finish: Aluminum is common for its durability and weather resistance. Choose finishes (black, white, mahogany, satin anodized) that match or complement your door frames and hardware.
Length and fit: Most astragals come in 80 inches. Confirm if your doors require trimming or if a longer length can be cut down on site. Check whether the model supports inswing or outswing configurations and if it’s field handed.
Security features: If central locking or flush bolts are important, look for combination astragal systems that integrate these components. Assess how the astragal engages with the opposite door to minimize gaps and reduce light leaks and drafts.
Weather sealing: A well-sealed astragal blocks drafts and reduces sound transmission. Consider models with tight tolerances and smooth operation across multiple seasons.
Installation complexity: Some units include installation instructions and pre-drilled holes. Field trimming and handed installation may require additional tools or hardware not included in the package.
Durability and warranty: Opt for corrosion-resistant finishes and a warranty that covers rusting, wear, and warping under typical environmental conditions.
Additional Considerations: Different Scenarios
- Residential double doors: Prioritize finishes that match common home exteriors and ease of install for DIYers.
- Commercial entrances: Look for heavy-duty astragals with high-strength bolts and robust mounting to withstand frequent use.
- French or sliding glass doors: Select astragals designed for both inswing and outswing doors, with secure mounting and weather sealing to block drafts from exterior conditions.
- Weather and energy efficiency: Choose models with snug seals to cut heat loss and reduce outdoor noise infiltration.
