Insulation advice for sliding patio doors

[and_the_noobie]

As the second winter in our new (but old) home approaches, we start to fear the heat retention once more.

I believe that one of the (possibly many!) culprits of cold air entering our house is the patio door which is sliding and just has a fabric brush to enable the sliding mechanism rather than any proper seal

From the pictures:
A) would folk here agree?
B) any advice on remediation work I could do to improve insulation and see us through the colder months?

Any queries, please yell - many thanks in advance

Wait and see what others say, but I really wouldn't worry about that bit. I would be looking for other gaps, we had one round our front door (Put in some brushes like you have) Check loft insulation, and loft hatch, holes in floorboards in cupboards (For pipes or cables to enter etc.

If you think it’s the gaskets that are letting in the draughts, then why not order a strip of replacement brushes ( it’s sold by the meter ) and if the sample will fit then you can replace the entire brush seal.

Get rid of it, bloody awful things. We had ours replaced with a window and normal door, made a huge improvement in both how quiet and how warm the room was in winter.

Isn't that a bit over the top, not to mention Our patio door (sliding) is fine, and unlike an "open it" door, we can open it just a few inches if we want.

Thanks folks - unfortunately (at the moment) replacing the doors isn't an option (much as I'd love to! - ££££ )

I will have a look at the fabric gasket seal replacement - was just wondering if there was anything else that could be done (different types of seals etc, or even an 'over-winter' solution) but seems like my options are limited :D

I wonder if this could help seal drafts. https://www.screwfix.com/p/stormguard-s ... pack/30322

I can't help but wonder, "you seem to be like a dog with a bone" Have you proved that the the patio door is "leaking" (air) I would be looking everywhere.

That's what opening windows are for.

Heavy curtains and a pelmet

sorry - I've been distracted by a long list of other jobs just lately... definitely a draft coming from it as we have long curtains and you feel the air blowing / being sucked through underneath them into the room in winter :)

thanks for all the suggestions folks :)

I see you have curtains already. I was serious about the pelmet not because I like things to look old fashioned but because it improves the efficiency of the curtains by preventing a process known as thermosyphoning . Hot air naturally rises , cooler air behind the curtains and against the windows is denser and thus falls drawing in and cooling the air close to the ceiling. All that cooled air is ejected at he bottom which in some cases can feel like a draught. The pelmet disrupts the air movements , perhaps granny knew a thing or two after all. I'd tape small lenghts of toilet paper at points on the door to see if or where and draught might be coming in.
