Hi,i keep getting people at my door about loft insulation, i tell them i'm not interested, the reason is i dont know if insulation in my loft would make much of a difference, you see my house was a steele house & years ago they built breeze block / pebbledash around it & put a roof on it , the roof is low , i cant even stand up at the centre of the roof, so as the insulation would be laid on what was the original steel roof would it make a difference ?
