When we bough out house we were told verbally it has cavity insulation.

We have nothing in writing and several other things we were tile have
tuned out to be incorrect. Is there an easy way to determine whether
insulation is present?

The injection holes should be visible, near the top of outside walls and
spaced 1m or so apart. They should be neatly plugged with consistent
material, if it was all done in one job. HTH

Assuming that it's a retro-fit - and not built in on day one - they will
have had to drill a matrix of holes through the mortar at intervals of about
1 metre in order to inject the insulation. They will have filled the holes,
of course, but they are usually still visible if you look closely.

Failing that, remove a brick and look inside the cavity. If there's nothing
but fresh air . . . you'll know the answer!

What's the age of the house?
What's the wall construction (e.g. brick outer, thermal block inner)?
Were you told what type of cavity insulation?
Some types used to be blown in through ~1" holes (and probably
still are for retrospective installations). If there are any areas
unplastered on the inside, can you see any such holes drilled every
few feet (and possibly mortared over). Might alternatively have been
done from the outside.
Have you ever drilled a hole right through the wall?

When our folks had it done in the 70's with that foam stuff, there was
plenty of evidence in the loft where there were quite a few spaces it
had escaped from.

What about drilling a hole through the outside brick?
I would presume you'd know if there was slabs put in with the build by
the feel of the grill on entering the cavity, or 'styrene balls might
come out if more recent addition.

At a guess.

No, well I dont remember so.

Now theres a thought, I dont think I have. Might do so this weekend.

Take a brick out, or a window / door.

Look in the loft, if its been sightly overfilled then some might be
visible.

Check for signs of carefully filled holes about 1m apart on the outside
walls.
You could drill the outside wall and see if there are traces of the
filling material on the drill or on a bent piece of wire that you stick
in the hole.

Another sign is comparatively low heating bills!
I had cavity wall insulation fitted a couple of years ago and the
difference is truly amazing. I can utterly recommend it to anyone. You
can also easily obtain a grant towards large part of the relatively low
cost(and no, I don't work for an insulation company).
If you find you don't have it, get it done asap.

Incidentally, I think it may also help somewhat with damp problems on
the internal wall. It would seem logical that moisture will condense on
the now much colder outside wall, having evaporated from the usually
warmer inside one. Just my guess.

If you have a suspended floor, and can get underneath for access, you
might be able to see insulation at the airbricks, as the wall cavity is
visible
at the airbricks.
