At Carbon, we build primarily with Insulated Concrete Forms (ICF) because we believe in homes that perform as beautifully as they look. ICF offers the strength, efficiency, and sustainability to deliver homes that truly stand apart - and will stand the test of time, too.

What Is ICF?

As explained in the video, Insulated Concrete Forms (ICF) are hollow blocks or panels made from rigid insulation, stacked and filled with concrete to create durable, energy-efficient walls. At Carbon, we use ICF for both foundations and walls to deliver strength, sustainability and a superior ‘lived experience.’

Sustainable and Energy-Efficient by Design

ICF construction is inherently more sustainable than traditional ‘stick-built’ methods, thanks in part to its use of recycled materials. The combination of incredibly dense thermal mass and continuous insulation significantly slows energy transfer, helping homes stay consistently comfortable throughout the year while using less energy. As building codes across the US continue to tighten, ICF homes are already exceeding today’s standards - and are well prepared for the future.

Lowering the Carbon Footprint

Concrete often comes under scrutiny for its carbon emissions, but it’s important to distinguish between concrete and cement - the main source of CO₂ in the mix. We use a recycled glass additive that replaces up to 50% of the cement content which maintains, and can even enhance, strength while meaningfully lowering emissions. Utilising ICF foundations also enables us to build thinner, high-performing walls; if your walls are 6” rather than 10”, that’s using up to 40% less concrete, which translates directly into a smaller environmental footprint.

Not Just Built Better - Lived Better

But what truly sets ICF homes apart is how they feel. One of the most noticeable differences in an ICF home is it’s sense of sturdiness. Thick walls have a calming, cocooning effect and temperatures shift slowly, taking days - rather than hours - to respond to outdoor changes. The result is a serene and secure environment that feels naturally comfortable.

Beyond sustainability and efficiency, for us, what matters most is the ‘lived experience.’ Everyone who lives in or visits a Carbon ICF home tells us the same thing: it just feels better.
