Absolutely Free Cavity Wall Insulation

I don't know about examples but reading about the damp and condensation caused by cavity wall insulation, it is putting me off the idea. Even with the government grant making it cheaper. I knew they would be a downside to the government 'help'. If it is anything like the rest of Gordons schemes it will be half baked and sub-standard. I have visions of contractors making a killng out of the subsidy and doing quick bodge jobs on many houses a day leaving a poor standard of insulation which will cause damp.

Vast numbers of Local Authorities and Housing Associations have/are installing cavity wall insualtion in their properties. They wouldn't be doing so if it had a detrimental effect on them, causing many millions of pounds of repairs to be carried out across the country.

I would like to know the full facts before making a commitment. The idea of contractors banging out quick, and maybe not top quality, insulations under housing department contracts doesn't surprise me.

Clearly, though, there are a great many satisfied customers who have CWI. These are all why I would like to find out all I can.

Also, as there are various types of 'filler' that can be used, presumably some are better than others?

This was posted on one of the other threads and certainly made my mind up on the subject of cavity wall insulation.

I live in a costal area , had the walls cavity filled 5 years ago and can honestly say have encountered nothing untoward, House is warm , no damp areas . I am waiting and wondering, what are the negatives of cavity wall filling?

Wow! Thanks for that. On balance, I am not inclined to go ahead now. Even if the risk is low, I am not going to risk the possibilities referred to in the article.

My house gets very hot in summer weather (when we get some) and that is one of the reasons I was thinking about CWI. Will just rely on the portable air conditioning unit we bought I think.

I can keep the house warm enough in winter but thought CWI might keep heating costs down.

Maybe it's better to leave things as they are, overall. It would be useful to hear from anyone who has regretted filling their cavity walls.

We had cavity wall insulation put into our old house. It did reduce heating bills significantly but I would not want to live in a house with it again. I found that during summer (and we have had some very hot ones in recent years), it was almost impossible to cool the place down, it seemed to retain the heat inside the house.

I can't have CWI in my 3-bed semi, although I would love to reduce my bills. The house was built 1930s and the cavity is not wide enough. Also, they then used brick ties between the inner and outer walls, not the small metal ones they used later. This (I have been told) would result in condensation patches on the walls where the brick ties were. I'm hoping that one day someone will invent a solution.

When we have a hot day I do as my Canadian relatives do - close windows and doors, close curtains or blinds in sunny rooms, just before the hottest part of the day.

First had house foam-filled in 1968. Moved house in 1975, and had our new home also foam-filled. Nary a problem during the 40 odd years. Highly recommended.

hi all,
i currently work as an installer doing cavity wall insulation. free grants have been available for years and years. most people get it for free through government grants and funding from the utility companies, mainly npower, scottish power,british gas and eon. if you do not qualify the most you will ever need to contribute is £149 which is a set price regardless of the size of your property.

there are two popular materials used to install insulation - mineral wool and bonbed bead. in my opinion, the bead is by far the best option as its waterproof, alot less holes are drilled in your property and its very very quick.

any questions guys dont hesitate to ask!
