The rigid insulation to the eaves on the second floor was installed earlier in the week, this is fixed around the perimeter of the building at the eaves only. This is due to the shallow pitch of the roof, as it is not possible to put the 400mm deep rockwool (used in loft space) here as reqiured, because the required U value would not be acheived. The rip liners to were fixed to the top and bottoms of the load bearing walls to enable follow on trades to carry out their works.The photos below shows the boards to the ceilings and walls being taped and jointed and intumescent mastic has been applied.
