Normally insulation board fits in the cavity between two wall surfaces. But is it ok if the wall didnt have a back on it (internal wall)
So say on a commercial unit, Im putting a metal stud wall close to the external wall of the building. But I cant get right next to the external building wall due to the Z purlins and verious other bits.
So I will have to sit the wall about 300mm away. Meaning I wont be able to board the back side to hold the insulation in place.
So I was thinking, bond the insulation board to the plasterboard and leave the back open....Is that acceptable
The reason im not using the inuslated plasterboard, is cause I can only seem to get it in 2.4m length, and as the ceiling hieght is 2.7m and I play to dry wall, I'd rather a full 2.7m high plasterboard for ease
