How to Replace Spray Foam Insulation: A Comprehensive Guide

Benedict Wallis • April 10, 2023

The process behind spray foam removal

If you have an existing spray foam insulation that needs to be replaced, you may be wondering how to go about it. There are many reasons why you may need to replace your insulation, including poor installation, water damage, or simply wanting to upgrade to a better insulation material. In this guide, we will walk you through the steps you need to take to replace spray foam insulation in your home and why Lofteaze are the right solution for you.


Determine the Type of Spray Foam Insulation You Have

There are two main types of spray foam insulation — open cell and closed cell. Open cell foam is softer and more flexible, while closed cell foam is denser and more rigid. Knowing which type of foam insulation you have will help you determine the best course of action for replacement. If not, we can help identify this for you during our initial visit.


Assess the Condition of Your Existing Spray Foam Insulation

Before you begin replacing your spray foam insulation, you need to assess its condition. If it is damaged, wet, or moldy, it will need to be removed and replaced. Additionally, if it was not installed properly or is not performing well, it may need to be replaced even if it appears to be in good condition.


Hire a Professional

It is important to hire a professional (such as Lofteaze) to remove and replace spray foam insulation. The Royal Institution of Chartered Surveyors (RICS) recommends the use of an independent expert, commercially separated from the installer/manufacturer, who can carry out pre-installation assessment tests.


Remove the Old Spray Foam Insulation

The old spray foam insulation will need to be removed before new insulation can be installed. This is a messy and time-consuming process that is best left to professionals. They will use special tools and equipment to remove the old insulation safely and efficiently. It can also be hazards to health so please do not attempt this on your own with out a professional.


Clean the Area

After the old insulation has been removed, the area will need to be thoroughly cleaned. This includes removing any debris, dust, or mold that may have accumulated. It is important to ensure that the area is completely dry before installing new insulation.


Choose a New Insulation Material

There are many types of insulation materials to choose from, including fiberglass, cellulose, and mineral wool. Each material has its own advantages and disadvantages, so it is important to choose one that is appropriate for your needs and budget. We can recommend the best possible solution and assist with the installation of the replacement loft insulation.


Install the New Insulation

Once you have chosen a new insulation material, it can be installed. The process will vary depending on the material you choose, but it is important to follow the manufacturer’s instructions carefully. Again, this is a job best left to professionals to ensure that the insulation is installed correctly and safely.


Evaluate the Results

After the new insulation has been installed, it is important to evaluate the results. This includes checking for any gaps or spaces where insulation may be missing. It is also important to check that the insulation is performing as expected and that your home is maintaining a comfortable temperature.


Consider the Cost

The cost of replacing spray foam insulation will depend on a variety of factors, including the type of insulation you choose, the size of your home, and the complexity of the job. The overall cost of spray foam insulation is usually between £20-£50 per m², but will depend on the thickness you go for.
