Fire batt installation of rectangular fire damper

In the past, openings for the installation of fire dampers in solid walls or ceiling slabs had to be of the exact size; only minimal tolerances were allowed, if at all. This has changed with fire batt solutions as they provide a new level of flexibility. With a fire batt, fire dampers can in fact be installed in openings that are much larger than the fire damper casing - the perimeter gap may be up to 400 mm wide. It is no longer a strict requirement that an installation opening fits the fire damper exactly.

My favourite bit was when the damper was perfectly flush with the block work like usual

Do you not need a mask when cutting?

What a load of rubbish. First of all since when you are allowed to mix materials from different suppliers?? Mastic from Hilti and and batt ( witch is intudeck and not Ablative board) from Firetherm????
Second of it should be compounded even if the damper is restrained and has a builders frame installed
The installer get bonus points for using the jig saw to cut the intudeck. never seen that before.
No wonder you have to replace al those defective details
