Cost To Insulate And Drywall A Room: The Lowdown


There are a number of ways to turn a house into a home, but for many, certain criteria have to be met to really be able to feel at home. The house must be warm, comfortable, and unique – encapsulating everything that makes you want to come home at the end of the day.

One of the best ways to achieve such a feeling, is by insulating your home against heat loss. This makes a home more comfortable, reduces the cost of heating your rooms, and creates a tranquil environment that you can relax in.

With the increase in energy efficiency, and the protection that professional insulation offers a property, this also helps to safeguard the future of your home.

But where to start with insulation, and what are the costs? Primarily, wall insulation is the first step for many homeowners. For this premium performing product, providing an extensive level of heat retention, and helping the walls to be more secure is the aim of the game.

However, the process of insulating the walls of a property can vary considerably, with the main variation being between insulating older properties and newer abodes.

Commonly, with older properties, insulation is installed behind a drywall, which poses the question, what is the cost to insulate and drywall a room? It’s time to find out…

What Is Involved In Insulating And Drywalling?

The solid walls of older properties, generally those constructed before 1919, means that either a cavity must be created on the inside, or the external walls need to be insulated. The cost to insulate and drywall a room is based on internal insulation.

Normally, this means that drywall is used to create a secondary wall inside a room. The new cavity is then filled with an insulation material, such as spray foam insulation.

The purpose of this is to provide a secondary barrier for your home, helping the heat to stay inside your rooms, and subsequently reduce your heating bills.

There are a number of further benefits to internal wall insulation for solid walls, such as increased soundproofing, structural support, and a raised energy efficiency. But, since there is a substantial level of work to be done, the costs can be fairly high.


Insulating your house is of the utmost importance, for both your comfort and the protection of your property. While internal wall insulation is a fantastic product, it can be enhanced significantly with the use of a wall coating!

Breaking Down The Costs Of Insulation

However, this can vary significantly depending on the style of house, additional work that needs to be done, the insulation that you choose, and what kind of finish you want. In many homes, insulating an internal solid wall can be very costly, and whilst incredibly beneficial, it is not always a possibility.

Thankfully, internal insulation is not the only option. There is quite an extensive choice when it comes wall insulation. A good choice is an external insulation that is fitted in a similar way to internal insulation.
