What size gap for doorframe ?
 

I'm building a thermalite wall between my garage and what will be a
utility room. This wall will have a door through. What size gap should
I leave for the door and frame ? Is there a standard size ? This will
be a firedoor if it makes any difference.


Many thanks.

I'm not sure about standard sizes but the ones I recently bought are 30"
X 78"
Two points I found when I had a similar situation were.
Firstly the BCO insisted on an automatic door closer, I used one
of the spring loaded chains that fitted into the hinge side of the door.

Secondly it was also necessary to have a step down into the
garage from the utility room so that any fuel spills in the garage could
not flow into the house.

There tends to be a minimum size for doors consistent with getting a
wheelchair through - I think its about 800 mm clear opening. Translates
to about 850 mm actual internal frame size. This from memory on the
'principal storey' (i.e. ground floor). Check the regs, even if you
think its ********, because even in the BCO agrees with you, he has to
enforce the rules..

Standard door widths, 762mm or 838mm. Add 3mm gap + 32mm lining + 5mm tolerance
on each side, so opening in blockwork = 80mm larger than door.
Standard door height = 1981mm. Add 3mm gap + 32mm lining + 5mm tolerance, so
height of opening under lintel needs to be 2021mm above finished floor level.
You could allow a bit extra for carpets etc, or trim the door to clear them
later.

Buy your frame, and build it in. This will make it easier to get
a good fixing, and you will be dead on for size.

I'd say AT LEAST 5mm tolerance. MAke sure the opening in the blockwork
is too big because it's easy to pack out the frame.

30" x 78" is still the standard size despite metricification

this is way easier. Or for those of us framing as we go, attach hinge
side of frame, attach door, put up other side of frame. It really is
far easier than mucking about trying to make everything fit later.

I do worry about some of the legislation though. Whats the point of
building a doorway suitable for getting a wheelchair through only to
have to have a step down into the garage!!

More not "joined up" legislation . . . .

I suppose that even if you put a ramp on the step for a wheelchair user
to use it would be unlikely that fuel could flow uphill into the house

Thanks guys, Just the info I wanted. I think I'll get the frame and
build as I go - good advice as usual.

Hi Tim

It probably doesn't apply to you here, but while it is simpler to build in a
frame as you go, this is only OK for softwood painted frames. Anything
unpainted like hardwood is probably going to get stained and damaged by plaster
and other subsequent work. A temporary frame is the way around this.

Normal wheelchairs will go through a 762mm (2'6")wide door opening but this is
really the minimum if you want to spare your knuckles. A 838mm (2'9") door is
better if you have the space. Legal requirements for care premises require
minimum 800mm clear opening width, so if the door only opens 90° then you need
to add the door thickness and the handle projection!

AFAIK there is no legislation that says the connecting door from an integral
garage into a dwelling has to be suitable for wheelchairs (even though that's a
good idea). I guess the regulations assume wheelchair users will use the main
garage door and then go into the house via the dedicated disabled-access point
if they can't manage the step. The intention of the step is to prevent fuel and
heavier-than-air gases from entering the house causing a fire or a noxious fumes
hazard, so if you have the space it could be argued that a ramp will work just
as well. If the BCO insists on a step then you could ask him about the
possibility of a grant towards a wheelchair lift!

Taping paper over the frame solved that - though I did have to replace
a bit of paper as it got torn. I reckon thats a quicker option anyway,
and it worked for me. Perhaps if youre paying a high price for
specialist timbers you might want to view it differently.

Ah. Thats not allowed either :-)

Well at least ONE of et exterior doors t our 'princial storey' must have
hard standing for a vehicle and ramp access to it.

Essentially you cannot bult houses that opnly have steps to get into
them. Period. And you can;t have them totally gravelled up drivewise either.
