Don’t dry-line,  Lime-Line or hemp-Lime

Conventional drylining is extremely bad for old masonry buildings           FOR OTHER INSULATION OPTIONS SEE OUR INSULATION CENTRE

It is a totally unacceptable solution because it Causes many more problems than it solves
It is a largely a cosmetic solution, hiding the damp problems
It moves the dew point from the wall surface to the cold wall behind the dry lining, dramatically increasing condensation.

The phenomena is know as interstitial condensation, which means condensation that occures within the fabric of the wall or roof, ie between or in the layers of the materials

Over time this will be a source of mould and fungal growth which is both unhealthy and very smelly.
Enjoy it for 5 years, after that you get to smell it.  

You can read some of the research on this by Joseph Little, Here, and Here,

Acceptable insulation solutions:

• leaves no voids or air pockets where moisture can accumulate
• Allows the wall to breath
• Does not alter the dynamics of the wall where the dew point is in the centre of the lime wall
• Adds to the thermal mass of the wall, ie not a soft insulating material
  
• Compatible materials with the original wall
   

This would include:

• Insulated Lime plasters, with particles such as cork or perlite
• Multipor and Calcitherm boards are bedded in lime
• Hemp shiv is mixed with lime and plastered on wall
