We often get asked how to deal with this. The very best solution is below:
1. Stick self adhesive Tecsound Acoustic Membrane around the pipe first overlapped at joins.
2. Wrap the pipe with FT55AL Pipewrap overlapping at joins. The rolls are 5.5m x 1.2m.
If the material is cut lengthways in 400mm strips you will get three strips at 5.5m long. This is enough to cover a 100mm diameter pipe 16m long.
3. For aesthetics box the pipe section in using double plasterboard sheets on timber frame and stuff it with any left over fibreous insulation.
Note:More than one layer of wrapping material can be used for greater effect. This is particularly advised at right angle bends.
