theres no gas fire, just a real condensation problem exacerbated by
Do you mean to comply with building regs?
Ther are tow or three ways currently used.
One is to mill a slot in the window frames and use nasty hit and miss
plastic vents. This is much favored in the trade when replacing windows,
because its quick and easy.
Another is to punch a hole through teh wall and put in short ducts and
'hit and miss' vents to allow you to switch em off.
Its also allowable to have a mecahnism that simply locks the windows
open a crack at teh top, but my inspector would not allow it on the
ground floor (insecure).
I with the hole drilling solution on this one. On the top of the top sash,
drill a few 20mm holes with a
spade drill bit and then cover them inside and out with grilles. The external
grille should have insect
mesh on it to stop creepy, crawlies from getting in.
right, where would i find suitable vent hole covers?
yes, thats what I was thinking in the first place: how would I do
this? I'm tempted to screw wood shims to the underside of the lower
sash - would that fly? Does seem rather crude, and I dont know what
depth of shim to use.
If I did that thered be no frame left. :) I could drill 25 or so 5mm
holes, but dont know what to use to cover them to make it look decent
and insect proof, or where to get whatever it is.
Thanks folks!, NT
Most of the DIY stores have plastic grilles which will cover the drill holes
through the timber. If you
can get hold of the grilles first, then use them to give you the sizes and
spacing of the holes they'll
cover, then drill the holes through the sash to suit. Even if you have drill a
load of small holes,
keeping them apart enough not weaken the timber frame, then use the grilles to
cover them and make them
Hope you understand this rambling 'cause I'se had a few beers for the new year.
Have a Very Happy and Prosperous New Year, NT. Good luck with it.
