Despite advice to the contrary, our daughter is buying a small wooden
shed to use as tempoary storage for garments - they'll be in there for
no longer than a week, she's a tailor/seamstress. We say the things
will get damp, she says "not in a week".
Any advice on improving the conditions inside the shed? It's going to
be about 8'x6' mounted on wooden bearers on a sheet of dpc material.
If this is the typical small wooden shed then the framing will be not
much more than 25mm square so the insulation possibilities without
extending the framing will be somewhat limited.
One of the things that I would consider is lining it with 9mm OSB -
walls, door, ceiling and floor. It was pointed out to me recently
that there is so much glue in OSB that it it is an effective moisture
barrier. Use 12mm and then it can be screwed into and things can be
hung from it.
insulation without heating makes almost no difference. At best it
reduces nightime condensation possibilities, so dew outside doesn't mean
In nay case dew will form on the worst insulated places - typically
windows - and run down them. It wont form on the clothing.
A greenhouse heater will make things worse, by increasing the
temperature of the air you increase its ability to hold water vapour.
That vapour will come from the wood if from nowhere else, because even
kiln dried timber still has a substantial water content and storage and
treatment of the shed after the wod was dried will introduce more. When
the temperature drops some of the moisture in the air will condense.
Insulation delays the inevitable, but does not completely abate rises
and falls in temperature nor will it dry out the wood for you.
Ventilation will help but an uninhabited shed is still going to be damp.
After a few months of use with pelnty of ventilation the shed may well
become dry, but my experience with sheds is that clothing (fabric of any
kind) develops mildew within a remarkably short time.
My experience is quite the reverse.
Only if its hung up damp, and sealed up, does it even BEGIN to smell musty.
Or if you have loads of flowers in pots full of vegetation transpiring
water like crazy. And no ventilation at all.
If these garments were stored in slightly damp conditions for a week,
what would be the result? Is that long enough for mould to start
growing? Garments don't mind damp per se, or we wouldn't use steam
I've had boxes of clothes and curtains in the garage for years. No mould.
keep em off the floor and away from the walls (concrete/masonry) and
they do very well.
I've got an unheated attic. Stuff doesn't rot their either. That's just
a shed on top of a house.
Really, this whole thread is a straw man. By and large all you have to
do to keep stuff is get it out of the rain and off the damp ground. And
away from mice. who will make nests in it.
would you leave clothes for a week in the boot of an unheated and
Would you store clothes in an unheated attic for a year?
Of course you would.
shed is no bloody different.
Is your shed rotting from mould inside it after 5 years? Nope.
Is grain stored in air conditioned dehumidified stores? Nope. Once its
moisture content is down, it stores fine, in unheated structures. No rot.
Rot happens when stiff is WET, not when its in moist air.
A shed in Natal, yes, clothes rot. Walls get covered in mould. They rot
in the bloody house. Everything rots in Natal. We simply don't have 100%
humidity and 30C temperatures for days on end here. They do. Even when
its 27C and sultry here, its NOTHING compared with places where stiff
rots unless you take special proprtions. Humidity here is generally
about 50%. In natal it peaks at about 85%.
Today humidity on a sultry July afternoon is less than 50% in the SE,
and up to 60, and even 70% 'ooop north' and in the west.
In an uninsulated shed. solar gain will drop that a LOT. humidity goes
down as temps go up. So every day te clothes will get bone dry.
And that's enough to halt any mould. Mould requires PERSISTENT damp.
Like putting a WET tent away inside a plastic bag. Or being permanently
below ground level. Or being in a persistently hot humid climate. Ours
They'll get damp in 7 hours let alone 7 days... Of course on a bright
sunny day it'll dry out if there is enough ventilation but come
winter, cold, rain and snow it'll be effectively sodden.
Insulate, line and provide some form of heating. Heating not from a
paraffin greenhouse heater as that will produce lot's of moisture and
smelly fumes. Gas won't be as smelly but still produce moisture.
Electrickery is your best bet, easy to control and clean. You won't
need much with decent insulation.
I would think that if the garmets are stored inside "dry cleaning"
bags they'd be fine for that length of time. Provided they aren't
squashed together, with too many hung on each rail. I'd be more
concerned about wildlife: moths/larvae eating the fabric, insects,
mice etc. Sounds like some nice warm nesting locations for the cold
(If that doesn't freak her out enough for an immediate change of plans
then nothing will :-) )
Yep! that way any moisture will be peramently trapped in the clothes,
ensuring that they rot.
I cannot believe the amount of total bollocks being spouted here.
I suppose in tehse days of suburnaites living in selaed double galzed
battery farms, and drying clothes by putting them in a heated tumble
dryer, the facst of living more or less out doors have been totally
lost from te fulture.
mould comes from damp stuff sealed up and put away.
You 'air;' things by hanging them out so air can circulate. This DRIES
them. It even - gasp - used to be done on washing lines OUTSIDE. I
wonder why we bother to ventilate rooves to stop them rotting. OBVIOUSLY
the only way this can be done is to seal them, up totally and run
humidifiers in them. I cant understand how all the stuff stored in my
shed for years hasn't gone rusty or rotted away. It must be a miracle!
No less than all the flags that are flown on poles, however do they not
rot when exposed not only to the dangerous un-dehumidified COUNTRY AIR
but also to the dangerous cancer inducing SUN and worst of all RAIN. Oh
my gosh. If ONLY we had listened to these suburbanites in their sealed
little boxes, our flags might last MONTHS instead of the TENS OF YEARS
they do last.
I cant understand why anyone would actually USE a shed when patently,
conditions inside them are so dreadful that you would be no better off
leaving things out in the rain and the sun.
Unlike houses, people do not sit in sheds sweating, take steamy baths in
them or cook in them. Thy have no sources of moisture over and above
what is in the air.
Get real folks. Keep the rain off, let the air circulate, stuff wont
rot. 2000 years of experience says so.
it will be no worse and no better than being outside hanging on a line.
(except they wont get rained on)
And indeed no worse and no better than being inside hanging in a
cupboard that is well ventilated.
You only get drier inside a house, in winter, when its heated.
The only danger I can see is if the temp drops rapidly at night and you
Shove a load of bricks in there. thermal mass wil keep it a bit warmer
