Saw a homebase deal for Knauff Earthwool 3 for 2
(you always know someone who needs a top up in a basic loft who won't shell out for PIR)

Gone are the days of under a tenner per pack.
Doubt this will apply to many / any on here, but y'never know.

Note this is only ;

Thermal resistance: 4.50 mK/W.
Thermal conductivity: 0.044 W/mK.

Yup, dusty lofts, but with 270mm the minimum? these days, that's a lot of homes needing an extra layer on top.
Many simply won't faff around with exacting cuts, foam fillers & tape over the top like folk here.
