I'm going to get a new front door. I need it to be a good secure one but also I have
a limited budget.
A steel front door and frame costs the earth. I've been quoted £2000+ which is too
A PVC door and frame vary a lot in price but also in security. They typically have a
3 point locking system (which is a good
thing) but I'm not sure just how strong a 'plastic' front door is? Anyone ever had
a break-in via a PVC front door?
A solid wooden door is probably stronger than a PVC door but I've been told wooden
doors can't have a 3 point locking system.
And wooden doors are vulnerable around the lock(s) and the wooden frames also tend to
splinter under force.
Any comments or advice very much appreciated!
Are the aluminium doors just an aluminium subframe with uPVC panels or they solid
I forgot to mention the door must have a wood grain finish to match other doors in
the stairwell. Do you know if the
aluminium comes with a wood grain finish?
They're made out of an aluminium box section - usually with one or more
double-glazed glass panels. For an outside door, a good standard of
insulation is usually required (even if not in your case). This is usually
achieved with a thermal break - where the box section is in two half-boxes
joined together with resin. I have also seen aluminium doors with a thin
layer of uPVC cladding on the inside.
You didn't say anything about wood-grain in the original question - nor did
you say whether it was to be partially or wholly glazed. I was assuming -
rightly or wrongly - that it was to be glazed. I have never seen a
wood-grain aluminium door. The usual finish is powder coating in either
white or brown - which is very smart, but looks nothing like wood grain. In
my view, wood-grain effect uPVC is not very convincing - the best way of
achieving wood grain being to make it out of *wood*!
Sorry, didn't mention no window in door.
What else are the panels made of? aluminium sheet?
Because it's in a block of flats I have to a door of similar appearance to the other
original front doors. Doesn't matter if
uPVC wood grain finishing not very convincing; just has to blend in.
My concern about wooden doors and frames, is they are weak around the lock because of
the wood removed to fit the lock.
I am assuming here wooden doors are hung in to wooden frames but maybe I can have a
You've said that several times - but I don't think it's particularly true. A
1/2" slot for a mortice lock inside a 1 3/4" hardwood door still leaves
plenty of meat either side.
Possibly - but are you trying to create Fort Knox? Obviously you want to
take reasonable steps to make it secure - but at the end of the day, if any
self-respecting villain is sufficiently determined to get it, he will do so
whatever sort of door you've got!
Sorry I've repeated myself but I assume most 'posters' are more likely to read
replies to their posts rather than all the
Would also need similar frame width for the lock keep. I don't know if it would be
possible to fit a door frame with 1 3/4"
Lol, not Fort Knox. I like to know my options and how secure each one is and, of
My main reservation about uPVC was the strength of the plastic (particularly the
panels) and the strength of the plastic
welds. As you can see there are differing opinions on the strength of uPVC.
I haven't seen multipoint locking wooden doors but will do a search for them.
My concern with wooden doors is that they are weak around the lock due to the wood
has to be cut out to fit the lock.
Did your door have a wooden frame (the bit fixed to the wall)?
A local window installer had, for some years, a uPVC window clamped down to
a piece of chipboard. There was a tenner underneath the glass. They
challenged anyone to get the tenner without breaking the glass or cutting
through the chipboard. No-one managed it during the time I was dealing with
them. uPVC is very tough and the multi-locking is very sound. When I had a
uPVC front door installed at my Mother in law's just over a year ago I
specified that it should only be openable from the outside with the key,
even if the door was 'unlocked'. I'm quite satisfied that the door is very
I've been to a local firm that make the doors on-site. The uPVC box sections look
pretty tough to me but they are plastic
welded together. I'm not so sure how tough a plastic weld is? Maybe that's a weak
point of uPVC doors?
The panels in a uPVC door are rather thin and they look vulnerable to me. The ones I
saw are a 5 layer sandwich. Layer of
uPVC, then insulation polystyrene, then thin bit of MDF or aluminium, then
polystyrene and then uPVC. To counter the
weakness of the panels I'm thinking of going for an 8 panels door, so if a panel or
two is removed the gap left should be too
small for anyone to get through.
Surely all front doors are key operated only from outside??
Not necessarily. I have a porch door with an outside handle - so we can get
under cover in a hurry when it's raining. There's another lockable door
between the porch and the house. We only lock the porch at night or when
staying away from home.
Nope - it's up to you to specify how you want it to operate. My porch door
can be opened from the outside with the handle when the door is unlocked
although the actual house door cannot of course. I have two sets of friends,
however, who had new UPVC front doors and were never asked how they wanted
them configured. As a result, unless the physically lock the door from the
inside, anyone can just turn the outside handle and walk in !

There are many wooden doors with multi-point locking available. I think
Wickes offer pre-hung ones with 3 point but you can also get more than this
from the specialists.
