Mr. Paul Forde:

I thank the Deputy for the question and I understand its significance. There is a great deal of logic in what the Deputy is saying but the question was not within the scope of my expert group. As of itself, we did not consider it.

However, I mentioned in my opening statement that the Minister outlined a number of medium-term investigations which had to follow, whereas we dealt with items that we got through in about two months or less than that.

The National Standards Authority of Ireland, NSAI, is undertaking reviews of the standards and of IS 465:2018.

It has also been asked to investigate the impact of cavity filled insulation. There is a report or an investigation under way so it is probably best to wait until that comes through.
