Cavity wall insulation - damage to brickwork

leeegglestone

Some of you guys may be able to help me on a similar topic. Just moved into a house, built about 1930s. survey said needed new Wall Ties.

Im having some Quotes done.
I wondered, If i need cavity wall insulation, should this be done at the same
time?

I was going to see if i was eligable for a Grant for the insulation, however this would be done by a separate company at a different time. Would it matter?

thanks for that. seems like cavity wall insulation brings up a lot of potential problems.

Clear as mud

My house was built in 1994 and has brick with thermal blocks and a cavity.

Should I or should I not get cavity wall insulation?

tbh I don't think it's really necessary to add wall insulation to a house built since 1995 - so you're a bit borderline.

I'd do everything else first. e.g. Get at least 350mm of loft insulation (and don't board over it).

Do you think there are negatives to the cavity wall insulation? I only ever hear the good stuff!

leeegglestone

negative if you read on the Pages posted above. thats what made me have second thoughts.

Yes it saves heat and money,but could cause other troubles

The troubles largely arise from poor ventilation - particulary where windows have been replaced and the new ones have no trickle vents (as they would have were it a new property) - and particularly in bungalows (which have poor air circulation).

The moisture comes from people ands their activites - breathing, cooking, drying clothes, baths and showers.

And people dont like to open windows - especially on cold winter days after they've paid out to get their walls insulated.

Sorry to go a bit off topic, my loft is one of the things I want to sort out. Not sure what insulation is there at the moment but I would like to lay some boards down for storage, I dont want to use it as a room but I do want neat storage.

Is it possible to lay boards raised to leave a breathing gap for the insulation? I think my brother did something similar in his house. Do I lay new insulation on top of the old or get rid of all the old?

Also I want to fit new PVC-u windows this year as mine are all wood. Do you recommend having trickle vents on all windows?

Still not sure if I should go for the cavity wall insulation though..

Cheers,
