Why do we use insulation such as Urea formaldehyde (UF) foam if its bad for you? Surely it should be banned?

The building regulations stipulate within document D1 that insulating materials which release formaldehyde can be used but only when there is a continuous barrier between the cavity and the habitable space. There are a number of codes of practice and British Standards mentioned which you may want to familiarise yourself with

BS 8208-1:1985 - Guide to assessment of sustainability of external cavity walls for filling with thermal insulants
BS 5617:1985 - Specification for urea formaldehyde foam systems suitable for thermal insulation of cavity walls with masonry or concrete
BS 5618:1985 Code of practice for thermal insulation of cavity walls by filling with UF
