InSoFast vs. Traditional Exterior Wall Assembly
Why pay more to just work harder?
We first published this blog May 21, 2015 to show you how much money you would save using InSoFast. This is about saving material cost not labor. That would be unfair InSoFast is only 20% of the labor.
In order to highlight the differences between InSoFast EX 2.5 panels and Traditional Exterior Wall Assembly methods, we have compared the two in terms of materials and cost. All numbers are based on the idea of working with a 2,400 sq-ft surface area, a wall that is 120 feet long by 20 feet high. This wall is built around today’s 11/17/2020 standards. We have always been ahead of our time. We did not know that we cost 30% less and we are 80% faster.
The quick answer:
Traditional method 80% more parts, work, and cost $8,805.77
- Or $3.67 per square for materials
InSoFast’s single step panel 20% of the work and cost $7,182.42
- Or $2.99 per square for materials
That is a savings of $1,623.35
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.
