The Chemistry Works. Now Comes the Hard Part.

The chemistry is proven. The question is which companies can survive long enough to change how we build.

For decades, the materials used to build homes have remained largely unchanged. Concrete, steel, insulation, and gypsum became standardized, widely available, and deeply embedded in building codes and construction practices.  

But as the housing industry faces mounting pressure to deliver more homes, at lower cost, with lower environmental impact, that status quo is beginning to shift. 

A new generation of material innovators is emerging with the promise of reducing embodied carbon, improving performance, and enabling more efficient forms of construction. From low-carbon cement and advanced insulation to bio-based materials and circular manufacturing approaches, the opportunity is significant. 

Yet innovation in construction materials is fundamentally different from innovation in software. A breakthrough in the lab is only the beginning. New materials must navigate complex certification pathways, prove reliability at scale, secure manufacturing capacity, earn the trust of builders and developers, and ultimately compete against entrenched incumbents with decades of market acceptance.  

We explore here the emerging landscape of construction material innovation, the barriers preventing many solutions from reaching scale, and what investors and other industry players can do to accelerate the adoption of the most promising technologies. 

The Technologies Trying to Make a Mark

Most material innovation falls into one of three core categories that make up a building: binders, envelopes, and structural systems.  

Reinventing the Binder 

Cement remains a prime target due to its significant carbon footprint.   

Companies like Sublime Systems and Brimstone are rethinking the process altogether. Sublime uses an electrochemical process that eliminates the need for fossil-fuel-fired kilns, while Brimstone replaces limestone with calcium silicate rock as its primary feedstock. Both have attracted significant commercial interest; Microsoft, for example, has reserved up to 622,500 metric tons of Sublime's future cement production. 

Others are focused on compatibility rather than disruption. Calgary-based CURA removes process CO2 from limestone before it enters the kiln while still producing ordinary Portland cement, claiming emissions reductions of up to 85% without requiring changes to existing manufacturing processes or construction practices.   

Reinventing the Envelope 

Insulation is another attractive target due to its widespread use and growing sustainability focus. 

TimberHP has converted a former paper mill in Maine into North America's first wood-fiber insulation facility, creating a domestic alternative to traditional insulation products. In Ontario, Hundred Year Materials is turning agricultural residues such as wheat straw and corn stover into sustainable insulation, with third-party validation of its thermal performance. 

Other companies are rethinking envelopes through circularity. Quebec-based PakVille diverts hundreds of thousands of recycled bottles (rPET) into structural building panels, while delivering superior thermal performance and enabling faster construction through lightweight, plug-and-play panel systems. 

Reinventing the Structure 

Some innovators are going beyond individual materials and reimagining the structure itself.  

Geoship is among the most ambitious, treating the home as an integrated product rather than a collection of components. Its geodesic domes use a proprietary bioceramic material that cures at room temperature and is designed to deliver the durability of conventional construction with a significantly lower carbon footprint. 

Meanwhile, mass timber continues to expand into larger and taller building applications, while mycelium-based materials use mushroom roots and agricultural waste to grow insulation and other building products in a matter of days.  

The hurdles to scale

Whatever the material, the obstacles are the same. The first is certification. A material is commercially irrelevant until it passes standardized fire, moisture, durability, and structural testing and earns evaluation such as CCMC in Canada or ICC-ES in the US, a process that is long, costly, and gates everything downstream.  

Next comes manufacturing scale-up. Producing a material in a lab is very different from producing it reliably at industrial scale. First-of-a-kind facilities must achieve consistent quality, operational reliability, and competitive costs while often establishing entirely new supply chains. 

Then comes market adoption. Conservative builders, insurers, and code officials are cautious when evaluating unfamiliar materials. Performance claims, pilots, and letters of support build credibility but widespread adoption typically requires years of demonstrated results. 

Underlying all three challenges is capital. Unlike software startups, material companies often require years of certification and tens or hundreds of millions of dollars to reach commercial scale. Yet venture investors are often reluctant to back capital-intensive manufacturing businesses, commercial lenders typically require proven operating histories and grants rarely provide enough support to bridge the gap from pilot to full-scale commercialization.  

How we and the industry can help, early on

Rather than giving up on materials innovation altogether as a component of construction technology, as many investors have, how can we help create at least better conditions for success? It is a question we spend a lot of time on, and it shapes much of what we do beyond writing cheques. 

Demand certainty is the most powerful lever. That is why our fund is designed to bring strategic LPs into our investment process as early customers and pilot partners, not just sources of capital. A forward purchase commitment does more than guarantee revenue; it signals to debt and equity financiers a genuine pull form industry. Public procurement pathways can also create demand by incorporating innovative materials into government projects.  

Industry partnerships and third-party validation offer needed credibility. This is one of the main reasons why we built the Centre for Housing Innovation (CHI) alongside the DMZ at Toronto Metropolitan University: to connect early-stage companies with the thought leaders, insurers and code officials who influence what actually gets adopted. We’d love to see this area expand as the Centre for Housing Innovation matures and partnerships are formed with groups such as the National Research Council of Canada.  

Industry-led growth capital. Many large builders and developers have in-house innovation arms, which tend to fund solutions built around a specific problem they already understand. That focus has clear value, but it also narrows the aperture and often stimies broader industry uptake due to understandable competitive considerations (when something works, why spread the good word to your competition?). This is in contrast with the collaborative work we do within Future Housing Canada. We [selfishly] believe a sleave of capital allocated to independent, third-party funds can help overcome this structural industry competitiveness while simultaneously providing a wider prospecting lens. Corporate LPs can then “double-down” on higher conviction areas through co-investment rights.  

Non-dilutive capital is the lifeblood of the lab-to-pilot stretch – it must be maximized. While this comment may seem obvious, execution is not. Navigating the grant and incentive landscape in any jurisdiction can be a job in-and-of-itself and it's a skill that takes years if not decades to refine. It also helps the underwriting process for VCs like us in that it allows founders to retain reasonable equity while also pricing equity rounds that truly reflect the aforementioned, domain-specific scaling hurdles.  

CURA’s path provides the playbook: a $1 million grant from NorthX Climate Tech, a validation partnership with a global cement producer and participation in an adoption accelerator, all before any meaningful priced round. That’s thoughtful and measured derisking and the type of approach we will take with our Home Innovation Fund.

The next generation of building materials will be defined less by the best chemistry than by who can survive the journey from lab to job site.
