Lath and plaster walls provided a measure of insulation, helping homes stay warmer in winter and cooler in summer. Due to its density, the thick layer of plaster dampened the transfer of noise from one room to the next.Do plaster walls retain heat?
Plaster is a Better Insulator Than DrywallYes, your plaster walls likely have little to no insulation behind them, but the wall covering itself has an R-value twice that of drywall.
Do you need to insulate plaster walls?
Properly installed insulation can help reduce your heating and cooling costs. Many older houses that have lath and plaster walls often have little or no insulation in the walls. Insulating the exterior walls in your home can help lower your heating and cooling costs by making your home more energy-efficient.Can you insulate over plaster walls?

They may also add cladding, another layer of insulation that sits between the blown-in insulation and the outer walls.Is plaster a better insulator than drywall?
Plaster is more sound-proof, but drywall usually means better insulation. A dense material, plaster blocks sound transmission much better than gypsum drywall. However, even though plaster is denser, it can't beat the thermal capabilities of standard drywall coupled with modern insulation commonly found today.Principle of Avoiding Condensation Explainer
Why are plaster walls so cold?
Lath and plaster walls provided a measure of insulation, helping homes stay warmer in winter and cooler in summer. Due to its density, the thick layer of plaster dampened the transfer of noise from one room to the next.Does plaster provide insulation?

Energy efficiency is the biggest reason why a thicker wall is better. Thicker plaster walls provide better thermal breaks than drywall, and that saves money on utilities.Why are old houses not insulated?
Classic, older homes may radiate beauty and charm, but they are often uncomfortably drafty – especially during cold months. Unlike today's airtight homes, many old houses have a natural ventilation system. They “breathe” through air leaks, and houses built before the 1960s were usually not well insulated.Is plaster a good thermal insulator?
Bims granule plaster has good thermal insulation properties comparable with typical thermal insulation materials (thermal conductivity equals 0.068 W/mK).Is it OK to drywall over plaster?
If your walls in your house are ugly or dull because of plaster that is past its prime or not to your taste, you can cover the plaster with drywall.

As mentioned earlier, avoid using nails on plaster wall because they will likely cause the drywall to crack. Instead, use a screw, because they won't break the plaster wall. Screws will also hold a lot better because they will fasten into the lath behind the drywall.What is the R-value of plaster walls?
According to Bon, plaster has an R-value of about 0.12/inch, so your plan will give you about 0.24. That little insulation is not going to be of any practical value (R-0.24 means you're stopping about 4% of the heat transfer).Should my walls feel cold?
