Thermal Lining Paper.

vickysh

Hi,
We have been considering buying some thermal lining paper to help with a cold wall in our house. In the winter time one wall in one room of our home has quite a bad condensation problem which completely disappears in the warmer weather. We have extra insulation and ventilation installed in the roof-space and there is still an issue there.
I noticed that it is possible to buy thermal lining paper which sounds really good from the reviews on the site (the brand I have seen is by wallrock but it won't let me post a link), however it is very expensive.
I was wondering if anyone here has used this product and if it was worth the money?

Thanks, vicky.

I think you may make the problem worse,

You could try mixing PVA glue with water and coating the wall 1 part glue glue to approx 20 parts water and give it several coats of this, I did it in a bathroom that was constantly damp and has pretty much resolved the issue !

Some thermal lining papers do not allow the wall to breathe as they are effectively polystyrene stuck to card. The more expensive ones claim to allow the wall to brethe so I would hope would not make the problem worse.

Are you completely sure what you are experiencing is condensation?

I, too, live in the same house - with Vicky - and have thought it to be nothing else but condensation. What else is it likely to be ?

Many thanks,

Hi Vicky
As you noted yourself, the condensation disappears in the warmer weather. This is how wallrock thermal liner (or are you talking about the insulating lining paper?) helps as well i.e. by raising the temperature in the room it stops the condensation. I doubt that painting it with anything will help - it's all to do with the dew temperature point being moved.

You mentioned that you've got extra ventilation - if I were you, I'd look at the efficiency of it. Without proper and working well ventilation everything will need to work much harder. You could consider using a dehumidifier as well (especially if you dry your washing in or near the room).

Cheers,

We've got it in our house above our bow windows downstairs and around the windows upstairs. My parents in law have done the underneath of their bedroom window with our leftovers, and they are happy with it so far. It is supposed to help with noise as well. I'm not sure how much it helps as we had a heat recovery ventilation system fitted as well. We bought our thermal liner from B&Q when they had one of their discount weekends. It is a bit of a pig to put up as it is very wide.

Thanks for the replies everyone.
The extra ventilation was only installed around march of this year on the roof so we haven't had a long period of being able to see how useful it has been due to the weather being quite warm. I am pretty sure it is condensation as when the problem initially appeared around Oct/Nov last year I thought it was a leak so called our home emergency cover out and the guy who came out looked all over the place and gave a really big explanation of it being condensation and how it forms etc....
This particular corner of the room gets virtually no sunlight in the winter months due to there being a tall building opposite which blocks the sun from that part of the house.
It was the wallrock thermal liner which I have been looking at, I am pretty keen to sort something out within the next few months before the cold weather kicks in as we are currently re-decorating so don't want to waste time painting a wall that gets ruined if we don't get the issue sorted.
We also have lights built into our ceiling above our stairs which don't appear to be fully sealed as the light is noticeable in the roof space which probably doesn't help matters with the extra heat being able to escape up too.
We have also considered getting a survey done to make sure there are no other underlying issues but as nothing came up in the survey when the house was purchased (April 2010) I think this could be a bit of a waste.
We do actually have a small de-humidifier which helps the overall air quality (i have asthma so without it i can barely sleep in the room) but it doesn't completely clear up the problem.
Anyway, thanks again for taking the time to reply. I think we may try the paper and hopefully it will do the trick.

The cost of the de-humidfier is also a problem. It is only a reletively small one, so we were advised to leave it on for a few hours. As a result, we sometimes reverted to leaving it on all day whilst we went to work.

As Vicky says, there has been quite a bit of the paint that has cracked and peeled off with the condensation from above. Need to try and resolve it before painting it again and it potentially doing the same thing again a few weeks or months after...:( :mad:

Never an easy solution ... good luck with whatever you decide to do. If you decide to use the thermal liner, I know where to get it at good price

The phenomenon is known as cold spotting. It's not condensation as such. There may be an air brick or other draught nearby which is cooling the wall too much. Failing that (it's a very strange and erratic thing, often without any obvious rhyme or reason), the usual correction is a thermal lining paper.

Thanks very much again for all your help and advice, folks.

One thing that I think that has been failed to have been mentioned is the fact that the NIHE Maintenance guys came round and fitted air vents / roof vents (not sure of correct terminology here) on the roof tiles, and although they said that this would erase this problem, it doesn't seem to have.

Is good to read your comments, and we can hopefully make steps to making this problem disappear in weeks to come...:)
