Is Spray Foam Insulation Waterproof In Colorado Homes?

This type of insulation is sprayed onto surfaces in a liquid form and then expands to fill in gaps and crevices. It is made of two components that are mixed and sprayed through a specialized gun. There are currently two methods of this insulation:

  • Open-cell spray foam insulation
  • Closed cell spray foam insulation

Open-cell is less dense and has a spongy texture. It is less expensive and easier to install than closed-cell. It is also effective at providing insulation and air sealing, but it does not provide the same level of structural support as closed-cell insulation.

Closed-cell is denser and has a more solid texture. It is more expensive and requires specialized equipment to install. It is also more effective at providing insulation and air sealing, and it provides a high level of structural support.

So, can spray foam insulation prevent water damage? The short answer is yes, it can. Here’s how:

  • Air sealing – Spray foam insulation helps to seal gaps and crevices in your home’s walls, floors, and ceilings, which is also known as air sealing. This can prevent water from entering your home through these openings and causing damage.
  • Waterproofing – Some types of foam insulation are specifically designed to be waterproof. These products can help to prevent water from seeping into your home’s walls and causing damage.
  • Drainage – Foam insulation can also be used to create a drainage plane behind walls and other surfaces. This can help to redirect water away from your home and prevent it from causing damage.
  • Structural support – Closed-cell foam insulation is particularly effective at providing structural support. It can help to reinforce walls and other structures, making them more resistant to water damage, unlike fiberglass insulation.

In the event of a flood or broken pipe, spray foam insulation can be an effective way to prevent water damage in your home. It can help to seal gaps and crevices, waterproof surfaces, and provide structural support. However, it is important to note that this type of insulation is not a complete solution. If your home has sustained water damage, it is important to hire a reputable contractor who can locate the source of the leak and repair it as soon as possible to protect your home’s porous structures from moisture damage.

It is always a good idea to regularly inspect your home for potential water damage and take steps to fix any issues that are found. This can include using foam insulation as a moisture barrier and creating an air-tight seal to protect your home from water damage.

Why Hire A Fort Collins Professional Insulation Contractor?

There are several advantages to hiring a professional insulation contractor for a spray foam insulation project:


A professional insulation contractor has the knowledge, skill, and experience to properly assess your home’s insulation needs and recommend the best type of foam insulation for your specific situation. They also have the training and expertise to properly install the insulation, ensuring that it is done safely and effectively.

Quality Insulating Materials

A professional insulation contractor will use high-quality materials and equipment to ensure that the spray foam insulation is applied correctly and provides maximum effectiveness. A professional will know which material or product works properly depending on the nature of the problem and the surface it’s being applied.

Code Compliance

This refers to the adherence to building codes and regulations that are in place to ensure the safety and structural integrity of buildings. These codes and regulations vary by location, and any construction or renovation project needs to comply with these regulations.

A professional insulation contractor will be familiar with local building codes and regulations and will ensure that the spray foam insulation is installed in compliance with these codes. This can include ensuring that the insulation is applied to the correct thickness, that it is properly sealed and protected, and that it meets any other requirements specified in the codes.

Failing to comply with building codes can result in problems with the insulation and potentially even structural issues with the building, which can have you fined and other penalties imposed. By hiring a professional insulation contractor who knows about the local building codes and regulations, you can ensure that your insulation project is done safely and correctly.

Good insulation contractors offer different forms of guarantees on their work, which can provide added peace of mind and protection against any potential issues with the insulation. In most cases, a contractor offering a guarantee or warranty on their product or service knows what they are doing.


Hiring a professional insulation contractor can save you time and hassle. They will handle all aspects of the project, from assessment to installation, allowing you to focus on other tasks or responsibilities.


In conclusion, foam insulation can be an effective way to prevent water damage in your home. It helps to seal gaps and crevices, waterproof surfaces, and provide structural support. However, it is important to use it in conjunction with proper water management and maintenance, including regularly inspecting your home for potential water damage and repairing any leaks as soon as they are discovered. By taking these steps, you can help to protect your home from the costly and damaging effects of water damage.
