| Main Door Materials |
Modern entrance doors are commonly made with aluminum, steel, engineered timber, fiberglass-reinforced plastic (FRP/GRP), or combinations of these materials. |
Confirm the material grade, finish, construction details, and suitability for the building’s exposure, maintenance needs, and local climate. |
| Door Construction |
Construction may include a framed leaf, insulated core, reinforced internal sections, surface panels, and a separate frame. Exact designs vary by material and intended use. |
Request drawings that identify the leaf, frame, core, reinforcement, seals, and hardware. Check that the quoted specification matches the complete supplied assembly. |
| Thermal Performance |
Thermal performance depends on the full door assembly, including the leaf, frame, glazing, seals, threshold, and installation—not on the leaf material alone. |
Ask for test results or declared performance for the specified assembly, using the method accepted in the destination market. Compare values only when test methods and configurations are comparable. |
| Weather and Air Sealing |
Perimeter weatherstripping, compression seals, sill details, and suitable finishes can help manage air and water ingress. Results depend on design, testing, and installation. |
Specify the required air, water, and wind-load performance for the project. Confirm the test configuration includes the proposed frame, glazing, threshold, and hardware. |
| Glazing and Sidelights |
Options may include glazed door panels, sidelights, or transoms. Safety-glazing requirements depend on the location and applicable building regulations. |
Confirm glass type, thickness, safety-glazing compliance, glazing method, and any project-specific impact or security requirements. |
| Hardware and Access Control |
Common options include hinges, multipoint locks, cylinders, handles, closers, and electronic access-control components. |
Check handing, backset, lock preparation, corrosion resistance, compatibility with local hardware standards, and whether electronic components are included or supplied separately. |
| Surface Finishes |
Finishes can include paint, powder coating, decorative laminates, veneers, and wood-effect surfaces, depending on the door material and manufacturing process. |
Request finish samples and care instructions. Verify color, texture, coating specification, and suitability for the installation environment before production. |
| Customization |
Manufacturers may offer variations in size, panel layout, color, glazing, frame design, and hardware preparation, subject to tooling and production limits. |
Approve dimensioned shop drawings and a written specification. Define tolerances, opening direction, wall condition, and measurement responsibility before order confirmation. |
| Fire-Rated Applications |
Fire-rated performance applies to a tested and approved door assembly; selecting a fire-resistant material alone does not establish a fire rating. |
For regulated applications, require documentation accepted by the destination authority for the exact door, frame, seals, glazing, and hardware configuration. |
| Quality Checks |
Typical production checks may cover dimensions, appearance, finish, component fit, operation, and packaging. Inspection scope varies by supplier and contract. |
Set measurable acceptance criteria and inspection stages in the purchase agreement. Agree on sampling, defect classification, and required records before manufacturing begins. |
| Compliance by Destination Market |
Building codes and product evaluation requirements differ by country and project. Standards used in one market may not be accepted in another. |
Identify the applicable local code, test method, labeling, and documentation before placing the order. Obtain confirmation from the project designer or local compliance professional. |
| Packaging and Shipping |
Door leaves and frames need protection against handling damage, moisture, and surface abrasion during storage and transport. Packaging should suit the shipping route. |
Agree on packaging, labeling, loading method, delivery terms, and inspection on arrival. Clarify responsibility for transit damage and any destination-specific documentation. |
| Industry overview: These are common product and procurement considerations, not a universal specification or ranking. Available designs, test evidence, and compliance depend on the individual product and destination market. |
