and ASTM E330. Fire performance, where required, must be tested as a
complete listed door assembly.
|
Good resistance to moisture, denting, and routine outdoor exposure.
Thermal performance varies substantially with core, glazing, and frame.
|
Wood-grain embossing, smooth finishes, stainable surfaces, decorative
glass, sidelites, transoms, multi-point locks, and custom panel profiles.
|
Skin material declaration, finish samples, water-absorption information,
assembly drawings, glazing data, and complete-unit test evidence.

|
EN 14351-1 may apply to external pedestrian doorsets in relevant markets.
Air, water, and structural performance can be evaluated using EN 1026,
EN 1027, and EN 12211 or comparable regional methods.
|
Lightweight construction with configurable thermal performance.
Thermal-break systems generally provide better insulation than
non-thermal-break profiles.
|
Profile depth, thermal-break type, glazing thickness, panel infill,
concealed closers, access-control preparation, thresholds, surface color,
and custom frame dimensions.
|
Profile section drawings, alloy and temper information, coating data,
glass certificates, air-water-structural test reports, and tolerances.
|
| Solid Wood Exterior Door |
Engineered or solid timber stiles and rails with moisture-resistant
joinery, exterior coating, and optional insulated panels.
|
Meranti
Oak
Accoya-type modified timber
Laminated timber
|
EN 14351-1 may be relevant for applicable external pedestrian doorsets.
Moisture content, coating durability, and wood-product legality should be
documented according to the destination-market requirements.
|
Strong visual customization and repairability. Dimensional stability
depends on timber species, moisture control, engineering, and coating.
|
Timber species, laminated construction, panel layout, carved details,
glazing, transoms, sidelites, stain or paint system, threshold type,
and multipoint locking.
|
Timber species and origin statement, moisture-content records, coating
system, joinery drawings, inspection photographs, and packaging plan.
|
| WPC or Composite Exterior Door |
Wood-plastic composite or hybrid polymer skins combined with a reinforced
frame, insulated core, and moisture-resistant edge construction.
|
Wood-plastic composite
PVC or polymer skins
Steel reinforcement
Foam core
|
Product-specific air, water, and structural testing is essential.
ASTM E283, ASTM E331, and ASTM E330 are commonly used performance methods
where accepted by the project specification.
|
Low routine maintenance and good moisture resistance when edge sealing,
drainage, and hardware reinforcement are properly designed.
|
Surface texture, wood-effect colors, panel geometry, glazing,
reinforcement level, sill design, smart-lock preparation, and
non-standard sizes.
|
Resin or composite composition, UV and weathering information, water
absorption data, reinforcement drawings, test reports, and installation
instructions.
|
| Thermally Broken Steel Door |
Steel door leaf and frame incorporating insulating barriers or separated
metal sections to reduce thermal bridging.
|
Galvanized steel
Stainless steel
Polyamide barrier
Mineral wool
|
Air, water, and structural tests may reference ASTM E283, ASTM E331,
and ASTM E330. Fire-rated versions require testing of the complete
doorset, including hardware, glazing, frame, and wall condition.
|
Higher security and impact resistance than many lightweight systems.
Thermal results depend on the barrier design and complete assembly.
|
Security level, bullet or impact resistance where specified, fire-rated
configuration, vision panels, louvers, access control, welded frames,
concealed hinges, and custom hardware preparation.
|
Complete assembly test reports, steel grade, weld procedure information,
hardware compatibility list, fire documentation where applicable,
and installation details.
|
| Exterior Patio or Folding Door |
Sliding, lift-and-slide, or folding system using multi-panel frames,
rollers or hinges, seals, tracks, and large glazed areas.
|
Aluminum
uPVC
Engineered timber
Insulating glass
Laminated safety glass
|
EN 14351-1 may apply in relevant markets. Air permeability, watertightness,
wind resistance, thermal transmittance, and operating-force testing should
be specified for the complete system.
|
Performance is strongly affected by panel size, glass make-up, seals,
drainage, threshold height, and installation quality.
|
Panel count, opening configuration, low thresholds, concealed drainage,
insect screens, laminated or tempered glass, handle sets, and motorized
operation.
|
System drawings, maximum panel-size limits, glass specifications,
operating-cycle evidence, drainage details, installation tolerances,
and replacement-hardware availability.
|
| Fire-Rated Exterior Doorset |
Certified door leaf, frame, seals, glazing, hinges, closer, lockset,
and threshold supplied as a compatible tested assembly.
|
Steel
Timber
Mineral core
Fire-rated glazing
Intumescent seals
|
Depending on market, fire resistance may be assessed under EN 1634-1,
UL 10C, NFPA 252, or another accepted national standard. The rating
applies only to the tested or approved configuration.
|
Fire ratings such as 30, 60, or 90 minutes are project-specific and
cannot be assumed from the core material alone.
|
Vision panels, panic exit hardware, smoke seals, acoustic upgrades,
access-control components, door closers, and coordinated frame profiles.
|
Valid third-party listing or test report, approved hardware schedule,
glazing approval, installation manual, labeling requirements, and
traceability records.
