Prestige Quick Close Cavity Closers - 100mm Multi Width Cavity Closer 2.4mtr

It did the job , would have liked a reduction in cost if bought more than 10

Excellent. Value for money product,

The cavity closers were over 50% cheaper than most other places that I had looked at. Easy to cut and fit. Used in an annex to close off cavity around windows and door.

Everything it says it is!
