Roof insulation costs

[Ronob]

For a while now I've been looking at these ads in the National Press from companies who spray foam on the underside of your roof tiles to insulate your loft, adhere the tiles to the roof and -no doubt- empty your bank account!

Does anyone have any idea what these companies charge, roughly?

I've tried calling them but all they want to do is send some bod in a suit to sell you the concept, they won't even hint at the cost

the concept of insulating under the tiles thus is on a "par" with a golf ball/bomb detector

Never seen the stuff in real life as we use sarkin boards up here, i remember the advertising campaigns for it in the mid 70's , 80's thought it looked impressive! but then i was young and naive.

Surprised its still being marketed tbh.
