Does anyone know the price of equipment to spray polyurethane into loft
spaces? I've had a few quotes and it seems very expensive considering the
cost of the chemicals from the likes of BASF. The web sites I have looked at
show a DIY set-up but this is not the best options as the chemicals really
need to be sprayed at around 24-6 centigrade

Are you looking for the diy equivalent of "Rooflock" and others of a
similar ilk? Because if you are considering that approach, my advice
would be "don't go there". There are far better methods of insulating
your loft which don't involve exposing the rafters to the risk of
rotting; make any future roof maintenance difficult and is guaranteed to
put off any potential future buyers.

Instead take a look at Celotex and Kingspan. Both are easier to work
with, as effective (if not more so) and their application is less likely
to lead to other long-term problems (as long as they're used correctly).

Cheers

Not enough, obviously, since firms are still doing it.

There are far too many problems caused by this treatment than it might
cure. For a start, it removes ventilation from the roof timbers and will
cause rot. And if you come to sell the house, a buyer's survey will likely
recommend budgeting for *complete* roof replacement.

Fix the roof by conventional means, then insulate in the same way.

Do you have any factual incidences to give, or are you making this up?

1) I know a roofer who worked on a perfectly good roof, some years later
after such treatment he had to rip all the timbers out and do a complete
re-roof as it was all rotten. He said he was glad he had not taken the
job on fixed price.

2) My nextdoor neighbor used to run a company who sold this PU treatment
(usually in industrial situations for energy management I hasten to
add). He did want it in his lovely Victorian terrace roof void though.
Got out of that business and went into playground surfacing instead.

If you actually took time to read the whole post you'd get your answer.

Nice to see you so rattled, BTW.

If spray-in PU foam is installed properly there will be no problems at all.
many, 1000s of them have been done. You also need a proper survey of the
roof.

Find a surveyor. Ask him what he'd say if surveying a property with this
installed.

His answer will be it's covering up a faulty roof. It's the only reason to
do it as conventional insulation is cheaper, more effective and better
looking. A win win win situation, as you'd put it.

So put a cross through that advert in your book of them.
