Suspended floor insulation

[nearthemark]

Hi there,

Would this be suitable to insulate a suspended floor, if supported by struts underneath that are perpendicular to the rafters?

Thanks,

Ps am going for Rockwool rather that celetex to prevent moisture build up

That will be fine. You could support it with chicken wire or even garden wire zig zagging between the joists fixed with screws. Make sure it’s a snug fit but not squashed up.

Thank you, I'd not thought of wire!
