Can pipe lagging for 19mm pipe be used on 15mm pipe?

thewiseowl12 · 2022-12-17 18:32:47

Grateful for any thoughts. Basically I need to lag heating pipes going into an old concrete floor with no insulation under the slab. Plumber was going to use 9mm tubolite pipe. I can get 19mm tubolite insulation for the 15mm pipes easily. Ie 15 x19mm pipe lagging However the only 25mm insulation I can get is for 19mm…

However the only 25mm insulation I can get is for 19mm pipes, ie 19 x 25mm
Could I use the the 19x25mm pipe lagging for 15mm heating pipe, or what would the disadvantages of doing so?
Thanks!
