I'm having a conservatory built on the side of my house and the lads have
been and built the base & dwarf walls, we are now awaiting delivery of the
conservatory which should be in a couple of weeks.
The walls are brick outside and Celcon/Thermalite inside and are 600mm high
with one side wall full height and a 50mm cavity.
It looks like a tidy job they have done but I have noticed that there is no
insulation in the cavity, is this not really needed or will it make a
difference to the comfort levels in winter if it is insulated.
I realise that it would be a little tricky to add batts now due to fiddling
around the wall ties but I'd rather do it now than regret it later.
Any input greatly appreciated,
From the amount of heat that ours loses through the windows and roof,
dwarf walls won't make a blind bit of difference. However, it is probably
good practice that they should do so. My tip would be to ensure that it is
a conservatory/orangery which must have a door between the house and the
conservatory. Otherwise it's an extension. (If it has a dwarf wall I believe
you can call it an orangery which sounds quite posh when you come to sell.)
Ours doesn't have the door but does have a double radiator and I suspect I
my winter heating bill if a door was fitted and the rad turned off.
Cheers for the answers - yes it will have a door between it and the house .
. .but as it won't be getting that much sun, I'm not optomistic enough to
think I'll be growing any oranges in it.
I have just had a conservatory built almost the same as yours.
They did put in insulation but did it after the walls were built by
just slitting the insulation down where the wall ties are.
Maybe they are planning on doing yours but may not do it until the
frame is fitted in case it rains alot in the next two weeks and the
insualtion holds in alot of water.
Why not ask them?

Which is not the way to do it. The insulation should be clipped to
the inner leaf if it's not fully filling the cavity. If it is
full-fill, it shouldn't be rucked or folded (as would happen if one
tried to shove it down a masonry cavity no more than 10mm wider than
the thickness of the batts). The wall ties should be every block
course vertically around reveals, so either:
a) there weren't,
b) they managed to find a way to slip the insulation in horizontally
as well as vertically, or
c) they did a half-arsed job of it.
