Exterior doors specification checklist
What to specify for exterior doors: material, core, frame, threshold, hardware, weatherstripping, fire and security ratings, and the documents to request.
Exterior doors take weather, abuse and daily use, and they are among the first elements people judge a building by. A good specification covers the whole door assembly rather than only the slab. The checklist below lets you compare quotes fairly and spot missing items before they become change orders.
Door leaf and core
| Material | Strengths | Check |
|---|---|---|
| Steel | Strong, often economical, good security | Insulated core, coating, dent resistance |
| Fiberglass | Stable, low maintenance, wood-look options | Skin thickness, frame, finish |
| Wood | Appearance, repairable | Species, moisture control, finish upkeep |
| Aluminum and glass | Entrances, storefronts | Thermal break, glass type, hardware |
| Stainless or specialty | Corrosive or hygienic areas | Grade and finish |
Specify thickness, core type, skin gauge or thickness, and how glass lites are framed and sealed.
Frame, threshold and weather seal
Most exterior door leaks come from the sill and threshold. Specify an adjustable threshold, a sill pan or flashing, and continuous weatherstripping at head and jambs. Confirm clearances and the swing, and check that the frame material resists moisture where it meets the floor. Align with the flashing guide for the sill detail.
Thermal values for glazed doors are rated like windows; see the windows checklist.
Hardware and security
- Lockset or multipoint lock, grade, and keying plan.
- Hinge type, number and weight rating; ball bearing hinges for heavy leaves.
- Closers where doors must self-close.
- Panic or exit hardware where required by code.
- Strike plate reinforcement and long fasteners into framing.
- Accessibility: opening force, threshold height and clear opening per local rules.
Ask which hardware is included in the price and which is allowance only; this is a common gap between quotes.
Fire, wind and special ratings
Where fire-rated doors are required, they are tested and listed as an assembly with the frame, glazing and hardware; field modification can void the listing. NFPA 80 covers installation and maintenance of fire door assemblies, and listing bodies such as UL publish certified products. For wind and impact areas, request product approval numbers accepted by the local authority. Do not assume a door has a rating because it looks sturdy. See also the fire-rated assemblies documentation checklist.
Finish, delivery and installation
Prefinished doors reduce site painting, but they require careful storage and protection. Ask about finish warranty and field touch-up. Check delivery for transit damage and confirm hand of swing before opening packaging fully. Install per the maker instructions and the project flashing detail, and check operation, weather seal contact and hardware alignment before sign-off.
- Shop drawing or cut sheet approved.
- Frame set level and plumb; shims at hinges and strike.
- Sill and head flashing installed before the frame is sealed.
- Sealant and backer rod applied around the perimeter.
- Operation and weather seal check, with a gap measured and recorded.
Documents to request
Request data sheets, test and rating evidence, warranty, hardware schedule, installation instructions and maintenance guidance. Specification of code-required items such as egress, fire ratings and accessibility belongs to the designer; confirm with the local authority.
Questions to ask a door supplier
- Is the quoted price for the door only, or the frame, hardware and installation too?
- Which weatherstripping and threshold are included, and how are they replaced?
- What are the finish warranty terms, and does the door need protection from direct weather?
- Are glazing, kick plates and louvers included?
- What certificates are available for fire, wind or security claims?
- What is the lead time for replacement parts?
Get the answers in writing and attach them to the order.
Questions people ask
What matters most in an exterior door?
The assembly: door leaf, frame, threshold, weatherstripping, hardware and flashing together. A strong door in a leaky frame still fails.
Which materials are common?
Steel, fiberglass, wood, aluminum and glass doors; each has different maintenance, insulation and security properties.
Do exterior doors need a fire rating?
Only where the code requires it, for example at some separations. Listed assemblies are tested with specific frames and hardware. Confirm with the local authority.
How do I compare door quotes?
Compare the full assembly with the same frame, glass, hardware, finish and installation scope.
