We recently had a new kitchen door fitted. It came with a UPVC
frame (it's an external door) that is roughly 50mm wide and the
door, which opens outward, closes against it.
I would guess that this is to reduce drafts and keep the insulation
value high.
However, this frame is also attached to the floor - where it
sticks up, above the floor by 2 inches. Although it doesn't
appear to be anything more than a piece of plastic I am firmly
convinced that someone, sometime is going to come a cropper on
this and end up face downwards in the back garden - having
tripped over the thing.

Personally, I'm considering getting the power tools out and lopping
a large chunk off this piece of frame. While that will probably
give rise to a draft from under the door, that does seem preferable
to a broken leg/hip/arm - not to mention the damage that could be
caused to the garden.

Alternatively, "the opposition" wants to get the installers back in
and have them remove the offending piece of plastic, or to do
whatever else would reduce the risk of a head-arse inversion.

What sort of remedies have other people resorted to. Popular options
could include looking where you're going, polishing the kitchen floor
and taking out additional life insurance or training the dog to always
be in the way - thus requiring potential trippers to tread carefully.
The idea of installing a ramp up to the height of the doorframe has
been vetoed: too much work and looks ugly.

Not a very clear description of yours, but if it is the 'standard
construction' the frame supports the entire assembly.

That "piece of plastic on the floor is an integral part of the welded
frame - and you will get used to it. My two grandsons (21/2 and 23 months
old) navigate both my plastic doors and frame successfully to get to the
garden to make a mess with the sand pit - and the external path is 8 inches
lower than the top of the frame sill.

That will severly reduce the integrity of the frame and will not only let in
draughts, but water as well - and probably cause a the door to misfunction.

It will also invalidate any warranty or guarantee that you have.

They will either refuse - or ask you to sign a disclaimer absolving them of
all responsibilty for damage or injury.

Simply learning to live with it - or you could ask the installer to make
another frame (at your expense) fitted with a narrower sill suitable for
disabled persons (IIRC).

Could you post a photo of the door on www.tinypic.com and post the link
here, so that the group can have a look? Seeing that, could lay rise to
better suggestions to resolve your problem rather than ruining several
hundred pounds of door.

Even the old wooden external door frames tended to have a threshold, not
as high as modern uPVC. I have three external uPVC doors, front, rear
and a 'french'door. All have highish thresholds but, so far, no one has
fallen over them.

Replace the bottom bit with a low threshold sill. Cut down the frame
if necessary, and refit so the disparity is a gap above the frame at
the top of the door. Fill in gap.

Yes, that's true. The old wooden frame was about half an inch above the floor,
with a small lip to act as draft excluder + rainwater dam.
I know that HSE diktats are meant to be applied to workplace environments
but I can't imagine anything like this design being allowed in an office
or factory - so I am a little puzzled why suppliers think it's OK to
design products like that for home use.

Isn't that normal ? Our 3 external doors are similar - no problems.

A bit risky fixing those to a 'hollow' UPVc frame Owain (which they are not
designed for [1]). You have to cut the frame to resolve the perceived
problem that the OP has, and that will create three separate problems.

1 Cutting the frame to fix the low-threshold sill, yet maintain
draughtproof and water integrity will leave nothing to fix the sill too
because of the way the UPVc is moulded.

2 Cutting the frame to actually get a fixing will leave a huge gap under
the door. That could possibly be resolved by gluing a suitable 'add-on'
piece of UPVc.

3 Cutting the frame to that extent will ruin its structural integrity.

[1] These are generally designed to fit onto a concrete floor, concrete
step or a very low timber door frame sill.

Low sills designed for the disabled may let water in if wind drives rain
hard.
We have such a sill on the side door into our garage which is great for
wheeled tools. Daughter moved in to a house that had been set up for a
disabled person and got rain into her lounge from the back door low sill.

Small shops with ordinary doorways often have a highish threshold,
usually an aluminium frame but you are right, in a factory/warehouse one
would expect yellow/black markings and warning signs for anything
similar. How far that is genuine H&S and how much management not
wishing to be sued is difficult to guess.

Personally I think they are ridiculous. Plastic windows I can just
about tolerate, followed by the bang-bang-bang a few years down the
road to get them open. Plastic doors are invariably ghastly noddy-
housed overpriced junk compared to a proper door. If you want security
a reinforced frame, steel plated wooden door, dog bolts & multiple
locks will meet any requirement.

Give me a proper engineered hardwood door and windows, with separate
secondary glazing and internal blind if you want the ultimate in
insulation. Acacia and other woods work well re limited winter/summer
expansion/contraction providing a good base for the top longest life
Sikkens paints & stains.

Solutions I have seen are create a raised section in front of & behind
the door frame lip, essentially creating a step which is more visually
obvious than the stupid "bit of aluminium or plastic extrusion
sticking out of the floor". Alternatively sink it into the floor so
only 1/2" is visible above the floor.

Traditional solution with a wooden door is set a small angle-iron lip
into the floor, which raises up just above carpet or finished floor
height. The door itself then has a lip with rain shedding rebate, and
a sloped approach to the door to direct water away. Some go for a fake
porch or real porch, but prevailing wind etc may negate their
effectiveness.

At times you wonder if the plastics industry would have us living in
an IP66 enclosure, with according aesthetics, to give them an
existence. Most plastic doors remind you Darwin is not allowed to work
and the human race is screwed.

No, mine is half an inch at the most. My dad's is 2 inches (that really sounded wrong) and every time I go there I fall over the blasted thing.

That's the 'trade-off' Hugh with the disability option - put up with
'tripping' over the standard setup (until you get used to it) or clear up
the water after its been raining. Personally, I prefer the first option -
less hassle in the long-run.

I know what the OP talks of. The conservatory in our last (rented) house had
one and I found it a right PITA due to being about 2" high.

My inclination would be to get 2 bits of 3x2" wood (oak is nice, but
anything fairly hard) and plane a slope into the top surface. Fix down
either side (screw, glue or silicone down depending what teh floor surface
is like).

Oil or varnish or paint the wood with something hardwaring and it will be
much better.

I'm OK with the sills Tim, until around this time of the year when I get
those bottles of Jack Daniel's off the family as Christmas pressies (they
know what keeps me sweet to do their odd-jobs free of charge [1]) - and when
I open those, I have been known to fall over the bloody sills a few hours
later on the odd occasion, to everybodies delight. :-)

The original front door in my Victorian house has a weather bar which
sticks up by about 2 inches. And the door is set back from the outside by
about a metre. Any outside door which hasn't got something like this will
allow driving rain in.

Profit comes first, they do not get to live with their creation...
... oddly enough architects do not have to either, although it can
haunt some.

Nothing to stop someone creating an engineered wood insulated door.
Insulated double glazing doors only use a panel of extruded
polystyrene (like Marmox) between two skins of PVC. Indeed, design can
make a big difference on plastic doors.

I don't follow this take a normal door/frameset and "set lower".
Surely you end up with a step at the door, down on the side it opens.
So with a normal inward opening external door you have step up going
out and the level of the ground outside is at the top of any seal
against the door. Very little to stop splashing or standing water
getting to that seal and running down into the building if it's not
100% perfect.

Personally I think most people are used to a raised cill and/or step
of some sort at external doors and it's not a big a hazard as it may
appear. All our external doors have some form of raised bit at the
threshold, never tripped over one yet. Bit of a PITA if trying to
wheel something heavy in, like a piano or woodburner though. Also a
problem for those in wheel chairs but as no one is (yet) we'll cross
that one if/when we come to it. Keeping the powder snow and driven
rain out is a much higher consideration.

Doors are available which have a thin metal threshold (about 4 or 5mm
high) instead of the normal plastic section on the lower horizontal
bit. Much harder to fit accurately an less draught proof.
There is metal inside the plastic frames to strengthen it up and
provide something to screw the hinges to BTW.

I fitted a low threshold on our aluminium back door. Works just fine and
doesn't let water.
However, I had no choice due to height of the opening, and I'm sure I'd
have got used to a step

Thanks for the responses, people.
The ideas about doormats and oak filler strips/ramps sound quite promising.
While these door seals are certainly not structural elements and could
be cut away, I think I'll leave the tools of mass construction in the shed
for the time being.

There is more to this episode than I've told. The rest may come out later
depending on whether the supplier honks me off more than they already have
and/or I need to raise a mis-selling complaint against them for other,
related, activities.

I think I'll pop out to the doormat shop at lunchtime ...
