Key Differences Between BuildBlock And Fox Block
BuildBlocks do not require any on-site assembly and are always ready to stack.
All forms of these blocks are fully reversible.
They create tight interlocks by stacking and locking securely into places.
As a result, they are solid. You won’t require any foam or clips between courses.
Besides, they come in industry-standard sizes.
On the other hand, Fox blocks are stacked with end-to-end interlock to provide superior structural integrity and strength. It uses horizontal reinforcing steel bars for interlocking when one layer of ICF is installed. It provides more strength and thermal resistance.
- Available Blocks
BuildBlock has 5 different forms of blocks. They are Straight Block Form, 90° Corner Block Form, 45° Corner Block Form, Brickledge Block Form, and Double Taper Top Form.

Insulation is one of the reasons people are using ICF for building residential and commercial buildings. Because of their thermal insulation, you can save money on utility bills over the years.
Buildblock has an R-value of R21, and Fox block has an R-value of R22. The R-value is the thermal resistance which shows how efficiently an ICF can resist heat from entering or leaving. Here, Fox block ICF has better thermal resistance than BuildBlock.
Fox Block offers a better warranty for its ICF. You will get a full 1 Year Warranty from this manufacturer. Within 365 days, you must inform any cracks or damages within 30 days of discovering them.
