We have this, rubber seals around the gaps like what you use on doors, duck tape and the worse windows we’ve brought sheets of plastic and stuck them on so it acts as secondary glazing. Oh and we have thermal curtains to

Likewise, the next door house is gradelisted and the listing someone comes onto mine I have had the back ones replaced but not the front due to the restriction my bed is right nex to the window so I can feel the draft coming from the sides

Unfortunately you will have to adapt to. It’s worse when it’s windy coz they rattle. Big sheets of plastic help in the winter. You can but shrink film wrap for the windows aswell. Only a couple quid from home bargains or pound stretchers.

I just have curtains on all the floors, the ground floor we’ve put on reflective film so people can’t see in but we can see out.

I’m in a flat so no one can see in, i will have a look at options

We had our grade 2 listed house windows fixed or replaced and we replaced many more than the council would allow, but how the hell are they ever going to know that you replaced a 20% destroyed window instead of fixing it like you should? Unless they have your house bugged I don't see how they could.

Oh wow looks good will I be able to open the windows?

Yes, but it will take about 5 minutes to remove all the caulk.

Ah great lol I like to open the windows I will have a better look in the morning to see where the gaps are visible and send some pics have a great evening
Can you not repair them? The wood has presumably shrunk/warped with age and I'd have thought period-appropriate repairs would be fine even on a listed building.

At a wet time of year like this wooden windows and doors should be at their tightest.

Mine are only 15 years or so old and there rubbish. Mind you it was done via a council restoration scheme and they’ve been thrown together
My father once mentioned he'd installed some very expensive hardwood sash windows on a large listed building when he was working as a carpenter / handyman, I'm pretty sure he said the manufacturer had used sprung bronze or brass to draft proof them.


Presumably something like this spring bronze weather strip (although it probably wasn't nailed on):-



I'm certainly no expert (thankfully I haven't lived anywhere with sash windows since I was a very young kid), but I would think that metal would probably work better on a sliding surface than rubber draft proof strip.
Do you have room inside the window for secondary glazing?

Yes I do
39626463-wlTc5.jpgHi all see attached pic of what my issue is I assume the gaps are all around the window but only where you can open the wondow
It’s just the bottom sash? Lift the bottom sash out and superglue some Schlegel down the sides of it. Should cover the gaps and still let the sash slide up and down

Failing that put some secondary glazing in. Might cost a few quid if you don’t do it yourself
my dad's house has double glazed shash windows and i have a house with similar windows and i haven't noticed any particular draft. they are new sash windows and not the old ones.

can you replace the sash windows with new double glazed sash windows? they are more expensive than UPVC but they can be just as good as the upvc ones.

Hey thanks, I did have a look at this and actually have UPVC in the back of the flat, however I am having issues with the council in letting me replace the front with UPVC!

Where can I buy these from? I did have a look online but no luck

A double glazing company will do it but they’ll be expensive. Unless you measure them and source them yourself. Their easy to fix in, just screws all around. Them seal round the edges. I personally would go for the Schlegel option. Cheap easy and quick

in period properties, shash windows add value to the property as they keep the property looking period. i sold a period house in london a few years ago and that had upvc double glazed windows. i thought they looked fine and i prefer them to sash windows, but when i sold the house, the developer took all the windows out even though there was nothing wrong with them and replaced them all with double glazed sash windows because they wanted to increase the value of the development.

if you put in new double glazed sash windows, the frame and glass structure will not be draughty as it is all one built unit. your sash windows are draughty because they are old. not all sash windows are draughty.
