Best insulating foam for PIR board gaps

    Evening all,

    I'm putting PIR boards (Quinntherm) between my joists for insulation. Naturally there are gaps where joist are not straight / boards are cut slightly badly.

    I've never tried foam guns before, so don't know what I'm looking for when it comes to a gun + the foam associated.

    Ideally it needs to have good insulating properties, fire resistant and good to work with.

    I'm doing large areas, so ideally something good, but not going to cost the world.

    This any good, or should I look elsewhere for something more specialist? - https://www.screwfix.com/p/soudal-window-door-installation-foam-kit-gun-grade/1740h

    This is another one of interest - http://www.insulation4less.co.uk/750ml-tin-fire-rated-expanding-foam

    Any thoughts?

    Best

    And make sure you buy some cans of gun cleaner,almost impossible to clean a gun after foam as set.

    Either clean it religiously or dont bother.

    I just leave the can on and it works as well as cleaning it in my opinion.
