Frequently Asked Questions
What is ICF Construction?
ICF Construction, or Insulated Concrete Form Construction, is a method of building that uses foam forms filled with concrete to create the walls of a building.
Find out more.

What is insulated concrete?
Insulated concrete refers to concrete that has been surrounded by insulation material to provide increased thermal resistance and energy efficiency.
Find out more.

Are there any Energy Savings with Insulated Concrete?
Yes, insulated concrete can result in significant energy savings, as the insulation helps to maintain a consistent indoor temperature and reduce the need for heating and cooling.

What are the Long term benefits of ICF?
The long-term benefits of ICF include increased energy efficiency, lower maintenance costs, improved durability, and better resistance to natural disasters like hurricanes and earthquakes.
Find out more.

How long will an ICF home last?
An ICF home is expected to last for many decades, with proper maintenance. The concrete used in ICF construction is durable and long-lasting, and the foam forms provide added protection against environmental factors like extreme weather and pests.

What are ICFs made from?
ICFs are made from foam material, typically expanded polystyrene (EPS), that is molded into interlocking blocks.
Find out more.

Can you use ICF for all the exterior walls in your home?
Yes, ICF can be used for all exterior walls in a home, providing a strong and durable building envelope.

How does ICF compare to traditional wood frame construction?
ICF construction provides a stronger and more energy efficient building envelope compared to traditional wood frame construction. Additionally, ICF is more resistant to natural disasters and pests.
Find out more.
What is the general cost of ICF walls?
The cost of ICF walls can vary depending on the size of the project and the materials used. However, on average, ICF walls are generally more expensive than traditional wood frame construction but can result in long-term cost savings due to increased energy efficiency.
How much does it cost to Build a home with ICF?
The cost to build a home with ICF can vary widely depending on factors such as the size of the home, the materials used, and local labor costs. On average, building a home with ICF can cost 10-15% more than traditional wood frame construction.
Do I need a contractor for ICF?
While it is possible for DIY builders to construct an ICF home, it is highly recommended to hire a professional contractor with experience in ICF construction for best results.

Is it easy to learn how to build with ICF?
Building with ICF can require some specialized knowledge and skills, so it may not be easy for everyone to learn how to build with ICF on their own. Hiring a contractor with experience in ICF construction is recommended.
Can I remodel and add to an ICF constructed building?
Yes, you can remodel and add to an ICF constructed building. However, it is important to consult with a contractor with experience in ICF construction to ensure the work is done correctly and the building remains structurally sound.
What is the Fire Rating for ICF blocks?
The fire rating for ICF blocks can vary depending on the specific product used. However, many ICF blocks are rated for fire resistance up to 4 hours, providing added protection for the building and its occupants.
Does ICF offer any resistance to mold and rotting?
ICF construction does offer resistance to mold and rotting as the foam provides a closed cell structure which doesn’t allow water to penetrate, thus avoiding the growth of mold.

Can ICF prevent ants, termites and other pests?
ICF construction can prevent ants, termites, and other pests as the foam is not a food source for these insects and the concrete provides a barrier they cannot penetrate.

Do you need a special concrete mix for ICF?
A standard concrete mix can be used for ICF construction, however, some manufacturers may have specific requirements for their blocks. It is best to consult with the manufacturer for the right concrete mix to use.
Should I vibrate the walls during the pour?
It is recommended to vibrate the walls when pouring the concrete in order to ensure a dense and consistent mix.

How do I install windows and doors with ICF?
Windows and doors are usually installed after the concrete has cured, by cutting an opening in the foam and installing the window/door in the opening.

Can I attach Drywall directly to the ICF wall?
Drywall can be attached directly to the ICF wall using screws and adhesive.

How do I install the electrical and plumbing?
Electrical and plumbing can be installed in the wall cavities before the concrete is poured, or after the walls are erected by cutting into the foam.

Do ICFs need any waterproofing when used in below grade construction?
ICF foundations can benefit from waterproofing when used in below-grade construction to prevent water infiltration.

Can ICFs provide an air and vapor barrier?
ICF construction can provide an air and vapor barrier, helping to maintain the indoor air quality and temperature.

Can ICFs be used for storm shelters and safe rooms?
ICFs can be used for storm shelters and safe rooms due to their strength, durability, and ability to withstand severe weather conditions.

What is the sound resistance (STC) of ICF walls?
ICF walls typically have a high sound resistance (STC) rating due to the dense concrete and the foam insulation, making them an effective barrier against external noise.

Can you pour an ICF foundation in the winter?
Pouring an ICF foundation in winter is possible as long as the temperature is above the manufacturer’s specified minimum temperature and proper curing practices are followed.

How long can ICF be exposed?
ICF can be exposed for several weeks after the concrete has been poured as long as it is protected from damage and the temperature is above the manufacturer’s specified minimum temperature.
Can you pour ICF in stages?
Yes, ICF can be poured in stages, but it is recommended to pour each section of the wall in a single pour to ensure a consistent mix and avoid seams.

Can ICF be left exposed?
Yes and no. ICF can be left exposed, and some designers choose to incorporate the ICF blocks into the design of the building as a decorative feature. However some sort of treatment would be necessary to protect the polystyrene from weathering and other deterioration. However, all types of common siding and even stucco can be applied to ICF forms.
Do you need to waterproof ICF?
Waterproofing is not necessary for ICF, but it may be required in certain circumstances such as below-grade foundations.

What can you build with ICF blocks?
ICF construction incorporates reinforced concrete as its core allowing you to build just about anything you want. This includes walls, foundations, floors, and more. Structures that can be built with ICF blocks are: houses, apartment buildings, office complexes, shopping centers, and warehouses.
Is insulated concrete safe?
Insulated concrete is a safe construction material as it is strong, durable, and does not pose a fire hazard. However, proper safety measures should always be taken during construction.
