Eco-Friendly and Affordable ICF Homes

Creating energy efficiency

Creating energy efficiency with insulated concrete forms.

Insulated concrete forms (ICF for short) are becoming more and more common as climate concerns rise - and for good reason! ICF homes are safer, more energy efficient, and more convenient to build than traditional wood frame homes.

What is ICF?

Insulated concrete form is a system of rigid insulation blocks made of EPS that are separated by plastic webbing. These blocks are used as a concrete form - during ICF construction, reinforced concrete is poured into the blocks to create a concrete wall (instead of a traditional wood plank or plywood frame). Once the concrete is poured, finishes (like drywall and siding) are attached to fastener strips embedded in the ICF walls. In the end, the ICF blocks fit together like Lego Bricks, which is one of the reasons ICF homes have such great energy efficiency.

Why choose an ICF Home?

Insulated concrete form construction has many benefits for potential homeowners. ICF homes have a tight building envelope and strong structural integrity. Houses built with ICF exterior walls typically require 32 percent less energy to cool and 44 percent less energy to heat than comparable wood-framed homes. Additionally, several steps of the construction process are also made quicker because the insulation and fastener strips are included with the ICF blocks, meaning that wall assembly is quick and easy. If you're ready for lower energy bills, a smaller environmental footprint, and a simplified construction process, it's time to build with ICF Construction.

The Benefits of Your ICF Home

Energy Efficiency

Each strong, durable ICF wall of an ICF home provides better insulation, more energy efficiency, and greater protection for you and your family than a traditional wood frame home. Since ICF blocks are blocks of concrete separated by two continuous panels of EPS foam, the flow of heat is significantly reduced and the blocks do not allow for thermal bridging (unlike with foam insulation). This means, we provide a thermal mass that is ideal for keeping homes environmentally friendly and reducing the cost to homeowners to keep their home warm while ensuring that hot and cold don't escape through breaks in the wall or insulation - because there are none! Our continuous insulation lowers costs for homeowners and is good for the environment. If you're interested in sustainable design and green building, ICF is the right choice for you.

Increased Energy Efficiency
Simplified Building Process

ICF homes also allow for a much simpler building process than a traditional stick built home. The construction process is simple and easy when the building materials are simplified (and easy to fit together). Even with the necessary additions of door and window openings to your ICF house, your home comes together with ease when you use ICF!

Safety and Durability

Our ICF homeowners are also better protected from natural disasters than owners of any traditional wood frame house. Our concrete pour is reinforced by steel, giving you all season protection. ICF constructed homes have resilient construction that stands up to the elements.

Plus all of this:

1. Continuous Double-Layer Insulation

Our insulation provides superior thermal comfort, energy savings, and sound mitigation. An R (resistance)-value of 23.5+ plus whole-wall high performance enables Zero Energy Ready builds.

2. Panels

Our panels create spaces with healthier air quality. Blocked wall assemblies have a PERM rating of <1.0, virtually eliminating moisture intrusion, mold, and rot from your list of concerns.

3. Reversible Interlock

Our block design saves construction time and reduces product waste, with a solid 2" parallel friction fit connection that's easy, versatile, and fast to assemble.

4. Rebar Support

We have one of the strongest wall assemblies available for below and above-grade walls, exceeding safety/resilience/durability requirements for FEMA-ATFP Federal Military Standards.
