Advantages and disadvantages of external wall insulation
In winter, homes get cold and heating costs more. So, it’s best to maintain your home warm. External wall insulation is helpful in keeping your home warm and is beneficial for saving energy. It helps your home stay warm and results in lower energy bills. However, not all wall insulation works the same. Some walls are good for outside insulation, but others are not. In this article, we will look at the top 10 advantages and disadvantages of external wall insulation.
What is External Wall Insulation?
External wall insulation is likely to create warm layers on the outside of your house. It helps to keep you warm inside. It is different from insulation inside the walls because it goes on the outside. This helps to stop the entrance of cold air into the house, and warm air remains inside the house as well.
External wall insulation can also make your house look beautiful and unique from the outside. It is a good choice for old houses that don’t have insulation inside the walls. It can help you save money because your home uses less heat to stay warm.
How Does Traditional External Wall Insulation Work?
Traditional external wall insulation means using soft, warm material on the outside of your house walls. This external material stops the heat from leaving your home. After using this external material, a hard cover is put on it to keep it safe. This helps to keep rain, wind, and cold air away from the warm layer.
This helps your house stay warm and comfortable in cold weather. If you want to add this kind of insulation to your home, FixSavvy can help you. They are experts and will do a good job of making your house warmer and saving you money on heating.
External Wall Insulation for Different Wall Types
Houses are made with different kinds of walls. Before wall insulation, it's important to know what type of wall you have in your house. This helps the insulation work better.
Here are the two types of external walls:
Stone Walls
Stone walls have small spaces with little stones inside. Water and air can move in and out. So, it’s good to use a soft wall that controls air movement.
Brick Walls
Brick walls do not let air go in or out. So, hard and strong insulation works best. The boards can be put on the wall, which looks nice and saves the home from rain.
Advantages Of External Wall Insulation
Here are a few of the best reasons why external wall insulation is suitable for your home:
- Save Money on Heating
External wall insulation will bring a warm layer to your home. This means you don’t need to use your heater all the time. This will save you money every month. - Feel Warmer and Comfy
The insulation stops cold air from coming into your house. It keeps warm air inside. So, your home feels warm and nice, even on cold days. This makes you feel warm and comfortable. - Keep All Your Room Space
Because the insulation goes on the outside walls, it does not cover the space inside your rooms. So, your rooms stay big and open. This is better than doing insulation inside walls, which can make rooms smaller. - Protect Your Walls from Weather
After using this external material, a hard cover is put on it to keep it safe. This helps to keep rain, wind, and cold air away from the warm layer. - Less Noise Comes Inside
The external wall insulation also stops sounds coming from outside. For example, traffic noise. This makes your home more peaceful. You can relax without loud noises disturbing you. - Stops Walls from Getting Wet
Insulation helps keep water and moisture away from your walls. Wet walls can cause problems and damage your home. This helps keep your home safe and dry. - Helps Save Energy and Nature
Because your home stays warm, you use less energy to heat it. Using less energy saves your money, and it is also good for the Earth to use less energy. It helps protect the environment from pollution. - Increases Your Home’s Value
If you want to sell your house later, having good insulation increases your home value. Wall insulation makes your home look nice and attractive. A warm and nice home can sell for more money. People like homes that stay warm and use less energy. - Good for Old Houses Too
Many old houses do not have insulation in the walls. External wall insulation is a better choice for the old home. It makes the home warmer and more comfortable without changing the inside walls.
Disadvantages Of External Wall Insulation
External wall insulation has many good things, but there are also some problems you should know. Here are the disadvantages of external wall insulation.
- Water Can Stay Inside Walls
Some walls need to let water and air move out. Sometimes during wall insulation, water stays inside. This makes the walls wet, which is bad for your house. - Mold Can Grow
When walls stay wet for a long time, mould can grow. Mold is not good for your health. It can also make the wall look dirty and cause damage. - Bad Air Movement
Some walls need to breathe, just like people. If the insulation blocks air from moving, it can cause problems. You may need to add small vents to fix this. - You May Need Permission
If you change how your home looks outside, you may have to ask your local council first. This is called "planning permission." Some homes need this before adding insulation. - Hard to Insulate Windows
Putting insulation around windows and doors is not easy. These spots are small, so hard boards do not fit easily. If you skip them, heat can still go out. - Makes Walls Look Bigger
After adding the boards, the walls look bigger. This can make your house look different or heavy, which some people may not like. - Expensive
This type of insulation is expensive. A small house can cost less, but a bigger house may cost more. You need to plan your money before starting. - Cracks Can Happen Later
Sometimes, small cracks can appear after the external insulation is done. This may happen because of bad weather or poor work. These cracks can let water come in again. - It Takes Time
The wall insulation is not done in one day. It can take many days to finish. It also needs dry weather and careful work to be done right. - Needs Experts
If you try to do it on your own, mistakes can happen. Bad work can cause big problems. So, it is best to contact experts.
