It is incumbent on the installer to carry out a borescope survey of the cavity to ascertain the suitability of the residual cavity for the installation. Insist on this and request a copy of the report. Notwithstanding this, there is always a risk increase.Thanks.
With the grant it would be virtually free.
Thankfully I'm not in a costal/hilly area so I don't think driving rain is a problem, but damp is still my only concern , for example what if the cavity is less than 40mm in places (the minimum required for beads).
Good call on a report.It is incumbent on the installer to carry out a borescope survey of the cavity to ascertain the suitability of the residual cavity for the installation. Insist on this and request a copy of the report. Notwithstanding this, there is always a risk increase.
Every time there is a storm my living room (upstairs) floor is covered in polystyrene beads.I've been told by a few different people who had this done that the same thing happened to them.
I presume you looked at addressing the source after the first occurrence? Any reason why it couldn't be addressed? With it being wind related there's a change some ventilation is not properly sealed but that's usually an easy enough fix.Every time there is a storm my living room (upstairs) floor is covered in polystyrene beads.
There is obviously a draught between the ground and first floor. The floors are wood and the beeds are coming from under the skirting. The house is rendered so short of removing it I am at a loss. It was a new build in 2003 and we bought in 2011. It is adjacent to a lighthouse on a peninsula so is subject to very strong winds. The house is warm because it is south face with a large expanse of windows.I presume you looked at addressing the source after the first occurrence? Any reason why it couldn't be addressed?

Fair enough. the issues are likely on the internal walls, holes for wiring or other services. If you're ever replacing flooring take off all the skirting and look for gaps that could be sealed.The house is rendered so short of removing it I am at a loss.

Do you have the walls pumped yourself ? What level of insulation was in the cavity previously ?Every time there is a storm my living room (upstairs) floor is covered in polystyrene beads.
All of this was done when the house was built in 2003. I remember the BER was low because of the number of windows, downstairs being open plan and tiled flooring. It was not possible to access the walls without causing remedial work. The house is warm but when there is a storm/high winds the beads are all over the room.Do you have the walls pumped yourself ? What level of insulation was in the cavity previously ?
