Can I Make My Own Insulation?


Insulation is an essential part of any building’s construction. It helps keep the home warm in winter and cool in summer while saving energy and money in the process. But when it comes to creating your own insulation, is this even possible?

The short answer is yes – you can make your own insulation from everyday materials like sawdust, straw, sheep’s wool, and recycled materials. However, it can be difficult to achieve the same level of insulation as traditional foam or fiberglass insulation. 

The most effective way to make your own insulation is to use loose-fill materials like sawdust, straw, or recycled material. These are combined with adhesives, such as borax or glue-treated paper strips, then layered in a wall cavity or attic space. The key is to ensure that you have enough layers of material that are securely held in place so that air cannot escape around them.

While making your own insulation saves money on installation costs, other expenses and problems may be associated with this project. You will need to purchase the necessary materials and tools, and you may need to hire a professional for help if this is your first time. Additionally, it’s essential to be aware of local building codes, as these regulations can affect the safety and effectiveness of any insulation project. 

1Why DIY Insulation Is The Right  Choice For You

Making your own insulation can be a great way to save money and create a more comfortable living space. It’s also an eco-friendly option, as you can use recycled materials and reduce the number of new materials used in your home. Plus, DIY insulation gives you the satisfaction of creating something yourself – which is always a bonus.  

Overall, creating your own insulation can be cost-effective if done correctly. However, it’s important to consider all the variables before taking on such a project – from local building codes to material availability and installation help. But with careful planning and proper precautions, making your own insulation could be just what you need for energy savings this winter.

2Cons Of  DIY Insulation

While making your own insulation can save you money and be an eco-friendly option, it’s important to note that there are some drawbacks. As previously mentioned, the effectiveness of DIY insulation is not always as great as traditional foam or fiberglass insulation. Additionally, DIY insulation can create air gaps in walls and ceilings if not installed correctly, leading to higher energy costs. And finally, since it’s a project that needs regular maintenance, you may spend more time and effort on repairs in the long run.

DIY insulation can be a cost-effective choice for those willing to take on the extra work – but it’s vital to ensure you understand all aspects of the process before beginning. If done correctly and with proper maintenance, DIY insulation can save you money on energy costs while also creating a more comfortable living space.

How To Make Homemade Insulation for Your Home Walls

This is a very detailed process and involves a few steps. 

  1. Gather materials: You will need sawdust, straw, borax, glue-treated paper strips, a caulking gun and caulk, and adhesive-like liquid nails.
  2. Measure the wall cavities you want to insulate: Use a measuring device such as a tape measure to take accurate measurements of each wall cavity, so you know how much insulation material to buy.
  3. Fill the walls with insulation: Place straw or sawdust inside the walls and fill them up until they’re full. Make sure you spread it evenly throughout the insulated area to get even coverage.
  4. Secure the insulation: Once the wall cavities are filled, use caulk and liquid nails to secure the insulation to the wall. Make sure it’s properly sealed, so air does not escape around it.
  5. Check for any gaps or holes: Use a flashlight to check for any cracks or holes in the walls where air can escape. If you find any areas that need additional sealing, use caulk or liquid nails to plug them up.


The bottom line is that DIY insulation can be a great option for those wanting to save money on energy costs and create a comfortable living environment. No matter which type of insulation you choose, you will be better able to control the temperature in your home while saving money on energy costs. Making your own insulation is a viable option – just make sure you plan it out carefully and use quality materials if attempting it. With the proper steps, you can keep warm this winter in comfort and style. As always, check with local building codes and hire professionals if needed to ensure safety and efficiency.
