Aluron / Aluminium entrance doors
AS 75 Door
The door branch of the AS 75 platform for thermally insulated external doors. Anti-bimetal solutions improve stability under temperature differences, with multiple threshold and fitting options.

VERIFIED PARAMETERS
Door performance is geometry, temperature and hardware.
For a tall external door, insulation is only one part of the problem. Temperature differences, panel/glass weight, closer, electric lock and threshold determine real operation.
Max. vent size
3000 × 1400 mm
Max. vent weight
280 kg

With AS 75 doors, thermal performance is only part of the picture. Leaf weight, hinges, lock, threshold and expected use determine the working configuration.

DOOR DETAIL
Closer, lock and threshold are specified together.
For a premium entrance door we freeze the opening scheme, access control, closer, threshold, pull handle and power supply before fabrication.
01
Hardware
Vent weight and geometry must match hinges, closer and lock.
02
Threshold
Finished-floor level, sealing and accessibility are coordinated before ordering.
03
Electrical
Motor locks and access control require cable routes and service access.
HOW TO READ THE DATA
Six values that shape the result.
A catalogue maximum is not the rating of every fabricated element. Classes depend on size, opening scheme, glazing, hardware and the tested configuration.
