Weatherization is a separate but related consideration. CDF supplies weatherization kits that include perimeter weather stripping, a door sweep, and a threshold. These kits are constructed from corrosion-resistant aluminum and are available in black, bronze, and aluminum finishes. Material options for sealing components include vinyl, neoprene, silicone, and nylon brush, each suited to different use frequencies and environmental exposures. For Philadelphia's climate, vinyl and neoprene provide durable performance through repeated freeze-thaw cycles.
For projects requiring thermal performance, ProBuilder supports selection of polystyrene or polyurethane door cores based on R-value considerations. During configuration, core options are presented alongside compatible frame and hardware selections. This workflow helps organize component choices for projects where insulation and weather resistance are priorities.
Hardware selection for exterior openings in cold climates should account for temperature cycling effects on mechanical components. Grade 1 commercial hardware is recommended for exterior applications subject to Philadelphia's seasonal conditions. Hinges, closers, and locking hardware rated for commercial use are designed to maintain consistent operation across the temperature range typical of the mid-Atlantic region.
