Thermafleece UltraWool Slab

ordered 13 packs of this to redo the loft insulation. order was very quick and turned up on 4 palets. packs were small enough to be manageable by myself but would be easier with 2 people.
insulation looks good quality and is quite dense. theres a sheepy smell to it but its not to strong and will air out after a while. i have used it before and was happy enough with it to have ordered more.
