Do you have family members playing musical instruments?
Is 2 storey living noisy for those downstairs?
If any of these apply to you then perhaps you should discuss with The Woolmen the advantages of using Acoustic Batt Insulation in your floors, walls and ceilings.
Acoustic Batts play 2 roles - limiting the sounds carrying from room to room and from upstairs to downstairs, and also supplying the insulation advantages of thermal batts.
This acoustic and thermal insulation combination has the same low allergen features of the thermal batt.
