Should Cavity Wall Insulation, flood from Kitchen Walls.

Most interesting unexpected Kitchen Incident'
I called Home Emergancy thinking I had lots of Insect Eggs gather in front of Kitchen Unit Kicker Boards, official info is Cavity Wall Insulation (little green Pellets) have found there way inside Kitchen.
Potential Rodent Hole and Traps etc are in Progress.

Should Cavity Wall Insullaton feed through Walls?

thanks

I've had that problem a few times when working on cavity walls.

It's not unusual then, that's important.

Nowadays a binder is added to stop this happening. If the fill is loose the beads can pour out when you cut into the wall. If any tradesmen know this in advance, they can have some have some batts ready to stuff into the cavity as they cut into it. You always lose a certain amount, so there will be a few voids that need filling.
Loose fill tends to settle over the years, so there will probably be a few voids anyway.

Excellent, Beads is the term I didn't use.
Finally is there any need. for me to arrange Walls to be checked, meanwhile Small Hole is to be repaired underneath Sink to stop Rodents.

thanks

Is this Small Amount

That's not too much to lose. Voids can be cold spots in the wall, attracting condensation and mould. You can check with a thermal imaging camera, or a surface thermometer. Voids are most commonly at the top of upstairs walls, under window frames, or reveals.
Another problem with under bonded or loose beads is ants taking soil into the cavity for a nest.
The colour looks like they were bonded.

I'm not sure if a Surface Thermometer is useful, if it did read Voids, I could be facing expensive buildings excess.
Mse points are valid as I'm top floor flat roof property, Single Glazed Kitchen Window only Double Glazed 2021.
I'll know over next 1-2 weeks if current Traps find anything.

thanks appreciated.

One very recent consumer rights Eco 4 letter leads to tel number for Ciga.
Seems these .gov eco schemes prev to v4 have 25 year cavity wall insulation guarantee.
Whilst I don't expect this to lead to repair, I have raised Ciga concern and provided photo's.

It's gone under unexpected circumstances, Cavity Wall beads did come through straight gap nearer kitchen internal wall -Sink Side, one wall.
Home Emergancy tidied it up, thankfully Kitchen de install old replace with b/q kitchen can recommence next week.

Homeserve were correct though never returned, there is a Gap in kitchen Wall Sink Side, 75% is covered by wood over Brick and the Gap is a couple of Inches from Floor i.e. above Floor Level.

It's taken my b/q Fitted Kitchen 'purchase' to View Cavity Wall Insulation Cleared Up.
I 've read this is u.k. wide concern going through House of Commons up-to June '24.
Kitchen Builder is busy between jobs, though starting to see some early progress.
