Insulation to internal framed walls

It doesnt appear you can add insulation to internal framed walls? Is there a way to do this manually if that option is not available?

thanks

Hi Truline: Yes use a recipe that is associated with a square measure. EG lining. As walls have 2 layers of lining per wall I’d recommend adding 1sqm of insulation per 2sqm of lining. If you add your cost code and supplier the quantities will be correct in your purchase order.
