Why work harder and pay more?
The real comparison is about material and labor. This is an unfair comparison, InSoFast costs less and is only 20% of the labor. The example we have here is based on a 2,400 sq-ft surface area, a wall that is 120 feet long by 20 feet high. SPOILER ALERT, InSoFast cost less and is 80% faster.
The quick answer: in $$
Traditional method with 80% more parts, more work, and cost $13,523.72
$5.63 per square foot for materials
InSoFast’s single step panel 20% of the work and cost $12,818.43
$5.34 per square foot for materials
For just materials that is a savings of $705.29

The Breakdown:
To highlight the differences between InSoFast EX 2.5 panels and Traditional Exterior Wall Assemblies, we compared cost and materials. InSoFast is 1000’s (THOUSANDS OF PARTS LESS ), to handle, manage, order, lose, and then reorder….
Compare InSoFast’s approach to typical construction methods.
Our cost analysis begins where the house wrap, (WRB), or Zip Wall type barrier ends, the exterior sheathing to the outermost finish. For comparison we finish the project with siding because, *using screws to attach the insulation system. Don’t let our choice of siding limit your creativity, both methods support a wide variety of finishes including stone veneer, stucco, brick and more.
*InSoFast can save time and money over load bearing masonry (concrete or block walls) using our patented adhesive attachment method that would not be a fair comparison.
What else are you losing or missing out on, other than profit?
We didn’t engineer our product to be less expensive we engineered it to be better. We focused on eliminating the complex variables that can muck up good intentions. We wanted something simple and effective. A secure, future-ready investment. The overall product cost and labor savings are just a bonus.
