Many people are not familiar with the term dry-lining wall insulation. In short, the process of internal insulation which is also known as dry lining walls insulation involves fixing insulation to the inner surfaces of your external walls and covering it with a vapor-like material barrier layer and plasterboard.

The best part about choosing this technique is that in this process insulation is can be included within the air gap between the wall and the board finish. The ultimate surface finishing can be given any color of your choice to look more elegant.

The material that is used usually used for the internal wall insulation is polystyrene, fiberglass, and polyurethane. Among these three mentioned materials Polyurethane is the most expensive one, but the plus point is that its thermal performance is significantly better than the other two materials.

Now I will explain how this type of insulation helps to warm your walls. As I mentioned before, the composite boards for internal wall insulation generally include a vapor barrier. However, the vapor barrier must be well sealed at wall, floor, ceiling, door, and window junctions, around light switches, and at all other breaks in the insulation otherwise; you would have to spend extra money later for the fixation. Hence, make sure whosoever you are hiring for the fixation is well expert in the field. This way you can get a cozy and warm feeling at your home for a long period.

Advantages of Dry-Lining Walls Insulation

  • The process is not time-consuming, though it depends on the size of your house.
  • You may save a significant amount of money while incorporating insulation against heat loss saves substantial energy costs in terms of annual bills.
  • The dry lining provides an architecturally pleasant at home.
  • The thermal conductivity is very low there is a low-risk of fire rating. 
  • In this type of insulation, there are no chances of rinsing water. Hence it prevents walls from seasonal damage and cuts down the repairing costs.
  • You can save substantial energy. The material used is also nontoxic. Hence, it is environment friendly as well.
  • When the final touch will be given by the company you have hired to insulate your home, it will not only look elegant but also save the walls of your home from the adverse weather.

Disadvantages of Internal or Dry-Lining Walls Insulation

One of the main disadvantages of internal wall insulation is the loss of room space; this may be minimized by using high-performance insulation products that are thinner. Hence, before choosing this option you need to re-check if the space of your home or kitchen is sufficient for Dry-Lining insulation installation, as it can result in the loss of space and persuades many people to choose the external insulation option.

What's more, when installing internal or dry-lining insulation in your home, the junctions of internal walls and floors with external walls may ‘short-circuit’ the insulation, which allows warmth to depart. 

Fastening of Insulated Dry-Lining

There are a plethora of ways can be used to fasten dry-Lining 

Dry- Lining insulation can be done through a plethora of techniques. If the partition is done with traditional timber or metal frames, then the initial insulation will be done with fiberglass, which is used to fill the gap between timber battens. 

On the pointed roof insulation, the primary insulation would be of a hard insulation board, for instance, phenolic foam with breathing membrane vapor barrier fitted between the space, and a further it will be fastened under this with construction nails that are usually used by the mechanics.

U Values and R Values


R-value basically a measure set by the UK government which tells us how well a particular construction material insulates. The more will be the R-value of your home, the better the insulation will be done, and there are more chances to save your annual energy bills. 


This particular measure is set specifically for the windows and doors of your home. The efficiency of the system depends on how low the U- Value is. Hence, this is typically a low number because it is a rating of how much heat energy is lost or gained through doors and windows. The U-values may vary as per the construction material used in the projector on the insulation material. There are very few contractors who will let you know about the detailed research data about the U factor of their products and their performance in conjunction with different constructional materials. 

  • Ultimately, the process of home insulation is as tedious as it seems. Therefore, to seamless the process it is imperative to choose a licensed insulation contractor who is not only certified but understands the deep aspect of your home along with U-Values and R-Values.

Also, there are a few aspects that you need to consider assure you are making the best deal.

  • Once the work is done, ask the insulator for the receipt as this is required by the norms.
  • Make sure you get the R-Value you were promised by the company you chose.
  • Once the job is done, check out your home, to make sure the insulation was installed appropriately.
