Im having a bit of a brain freeze moment, so please help:
Loft is 4.2m x 8m
Insulation roll size (100mm deep rolls)
Width 1140mm
length 7.28m
Area per roll 8.3 m2
So do i only need 4 rolls???

Nah, seven 1140mm "widths" on the 8m loft dimension, each run would have either zero or one place where the a length ended and another began. Four rolls should work just about perfect.AndyMc..... wrote: »Bear in mind you could be !!!!ing about with unsuitable off cuts.Proud member of the wokerati, though I don't eat tofu.Home is where my books are.Solar PV 5.2kWp system, SE facing, >1% shading, installed March 2019.Mortgage free July 20230 -

The insulation arrive and its not in rolls, looks like rolls when packaged but are actually 'block' shaped, Im guessing to go in wall cavities? Im assuming they're still OK for the loft?0 -
I guess That would be slabs - without opening them - what size does it say on the packing, and what's it called?0
