OK short answer is yes, this system was in use in England, indeed may still be being used
Was sold as a remedy for.
1/ Lack of insulation in the loft
2/. Prevented the tiles [that were exposed in the loft,] no felt or timber or ply used, from rattling in the wind.
3/. Stopped draughts in the loft space, yes seriously this was a sales pitch.
A short while after the spray was applied the timbers started to rot, because there was no ventilation getting to the timber coated in spray, any ingressing rain water ran across the top of the insulation + with no ventilation of the timber rot is inevitable
Disastrous system, should be banned.
What happens with you?
