Direct Answer: Element ICF outperforms Fox Blocks and Nudura in Massachusetts due to its "Knock-Down" logistics and reinforced corners. While Fox and Nudura are excellent products, Element's ability to ship flat and assemble rigid on-site solves critical site access issues.
At BlueGreen, we aren't married to a brand just for the sake of it. We've poured Nudura schools. We've built Fox Blocks basements. We know the pros and cons of each.
But when we standardized on Element, it was because of logistics and corners.
The Logistics Battle: Rigid vs Folding vs Knock-Down
In Massachusetts, job sites are tight. Getting a 53-foot trailer onto a Cape Cod driveway is a nightmare.
* Fox Blocks (Rigid): You are shipping air. A trailer fills up fast. If you need 4,000 sq ft of block, you might need two trucks. That's double the shipping cost.
* Nudura (Folding): A massive improvement. The blocks fold flat, so you get more on a truck. But the hinge is a mechanical weak point during the pour.
Element (Knock-Down): The webs detach completely. We can pack the foam panels flat and the webs in bags. We can fit an entire 4,000 sq ft house and* the garage on a single load.
The Corner Fight: Who stays straight?
The corner is the most dangerous part of an ICF pour. It's where the pressure concentrates.
Nudura's folding corner is convenient, but under high vibration, the hinge can flex. We often had to strap Nudura corners heavily.
Element uses a separate "HV Clip" that ties the inside and outside panels together with steel-like rigidity. When we pour a 10-foot corner with Element, it stays 90 degrees. We don't spend half the day cross-bracing it.

Prices fluctuate, but Element is competitively priced against the big national brands.
In 2026, the raw block cost is usually within cents of each other. The savings come from:
1. Shipping: One truck vs two. ($1,500 savings right there).
2. Waste: Element's web is reversible and reusable.
3. Speed: Our crews move 15% faster with Element because the interlock is more positive.
Summary: Why We Stock Element
We keep Element in our Plymouth yard because it solves the problems our local builders face. If you run short on Nudura, you might be waiting a week for a truck from Canada or the Midwest. If you run short on Element, you drive to Plymouth and pick up a bundle. In construction, availability is everything.
