Now I opt for a low-density insulation foam of the sort the manufacturers fit to high-rise buildings without telling the residents that they're highly flammable, because that way there's more money to be made... although I realise now that this is the last time Celotex are likely to let me use their product.
There is admittedly a 'health and safety' advisory printed on the sheet, so they can't be all that bad, can they?
I'll let you read that while I drink my cappuccino, and you can tell me all about it later.
(You can tell this guy was an airline captain, huh?).
