Domestic & commercial
Product options cover a wide range of doorway and traffic requirements.
Millimetres matter
A small floor-level difference can still interrupt an accessible route
Door thresholds often look insignificant compared with a step or staircase, but even a modest raised edge can create resistance for wheelchair wheels, shower chairs, walking aids and other wheeled equipment.
Low-level threshold profiles are designed to manage those smaller junctions. Rather than creating a conventional access ramp, they bridge, cover or transition the point where two floor surfaces meet.
The important detail is the cross-section. A flat threshold suits a different floor relationship from a transition profile, while a wet-room doorway may require a flexible barrier that controls water without creating an unnecessarily rigid obstruction.
Start with the floor junction
Four questions identify the profile
01
Are both floors the same height?
If they are, a flat saddle profile may be sufficient.
02
Is one side higher?
A transition profile can bridge between unequal finished levels.
03
Is this a wet / dry boundary?
A compressible shower threshold may need to provide both access and water control.
04
How wide is the junction?
Threshold width must suit the frame, floor build-up and surface that needs covering.
Read the cross-section
The four ranges solve four different junctions
The category becomes much easier to navigate when the thresholds are compared by profile rather than simply by width and length.
12.7mm high
High-flat
A deeper flat aluminium saddle with products for different traffic demands, including specialist versions intended for floor-spring door installations.
Unequal edge heights
Transition
A sloping grooved profile that bridges different floor heights, with current AWS options transitioning from 6.4mm to either 12.7mm or 19.1mm.
Compressible
Wet-room barrier
A flexible neoprene profile that acts as a water barrier while compressing beneath wheelchair and shower-chair wheels.

Compressible Wet Room Thresholds
Aluminium and neoprene shower-door thresholds that create a flexible water barrier between wet and dry floor coverings. The gasket compresses as wheelchair or shower-chair wheels pass over it.

Simplified cross-section
The flexible neoprene element provides a raised water barrier during normal use, then compresses as wheelchair or shower-chair wheels move across it.
Wet-room threshold
Sometimes the threshold needs to move
A wet-room doorway creates an unusual requirement: it may need a physical barrier to help control water while remaining easy to cross with wheels.
AWS compressible thresholds use an aluminium base with a flexible neoprene gasket. Current options are supplied in nominal 13mm and 25mm heights, with the compressible element reducing to approximately 10mm as wheels pass across it.
Wet to dry transition:
intended for the junction between wet-room and adjoining floor coverings.
Flexible rather than rigid:
the neoprene gasket deforms under wheelchair and shower-chair wheels.
Water management:
the raised profile acts as a local water barrier at the doorway.
Flat or transition?
Look at both sides of the doorway
The profile should correspond to the finished surfaces it is joining. A flat threshold and a transition threshold may look similar from above, but their cross-sections solve different problems.
Similar levels on both sides
Flat low-profile and high-flat thresholds create a saddle across the doorway. They are most relevant where the surrounding floor relationship does not require the threshold itself to make a significant height transition.
Different levels on each side
Where one finished floor sits higher than the other, the transition profile changes height across its width rather than creating the same edge condition on both sides.
Surface detail
The grooves are functional, not decorative
The aluminium threshold ranges use grooved upper surfaces rather than completely smooth plates. That texture increases surface grip across the junction for both wheeled and pedestrian movement.
Because these products sit directly within the travel path, the surface condition matters just as much as the profile geometry. Dirt, sealants, damaged fixings or unsuitable installation can all undermine an otherwise well-selected threshold.

Before choosing a threshold
Six details determine whether the profile fits
Measure the actual finished doorway rather than selecting solely from the nominal threshold height.
Floor height each side
Measure both adjoining finished surfaces so you know whether the junction is genuinely flat or requires a transition.
Required width
Choose a profile wide enough to bridge and cover the complete junction without interfering with the door operation.
Doorway length
Measure between the relevant jambs and account for any cutting or notching needed to suit the frame.
Floor construction
The substrate affects the fixing method and whether screws, adhesives, sealants or another preparation method is appropriate.
Door hardware
Check clearances and identify specialist details such as floor springs before selecting the threshold profile.
Wet or dry environment
A wet-room boundary may require water-control behaviour that a conventional flat aluminium threshold does not provide.
Check the complete product specification before installation: profiles within the same category can differ in aluminium gauge, fixing-hole preparation and intended traffic or door-hardware application. Follow the current manufacturer instructions for the exact threshold selected.
Start with the cross-section
Match the threshold to the finished floors on both sides
Choose a low-profile or high-flat saddle for similar finished levels, a transition threshold where one side is higher, or a compressible system where a wet-room water barrier also needs to remain easy to cross.
