The Compared Costs of Insulating a Basement

How does InSoFast measure up when it comes to cost and labor? This page shows three typical basement remodeling situations and draws a comparison between the "Big Box" method and the InSoFast method for handling those situations. We check out factors like the cost, weight, and delivery of materials as well as the average number of parts and pieces you'll have to deal with during your installation. At the bottom, we've included a list of competitor manufacturers who've also decided to start making "easy" basement systems.

When we say Big Box, we are generally talking about methods that are available at large home improvement super stores such as wood-framing and foam-board insulation from Home Depot. Such methods are complicated and timely. The average homeowner will likely hire a contractor to perform that work which adds an additional cost to the project. Our comparison does not reflect any cost associated with taxes, shipping or hiring contractors, but keep in mind that we offer free shipping and our panels are designed for do-it-yourself simplicity.

Side Note: We've had octogenarians install our product in a weekend!

Totals (excluding the InSoFast Panels) are based on material and pricing from Home Depot Online as of February 2014. The recommended Loctite 3X Stronger PL Premium Construction Adhesive is available at Lowes and Home Depot. Using a 28 fl oz cartridge, a 3/8" bead will serve 6 InSoFast panels (48 sq ft).

2 Walls: Half Basement

35 ft × 8 ft = 280 sq ft Total Wall Area

In this example, we are only insulating two outside walls of a basement (measured in the diagram). The floor-to-ceiling height is 8 ft and the total length of the walls to be covered is 35 ft (15 + 20). Multiplying the total length by the total height (35 × 8), this project requires material that will cover 280 sq ft.

InSoFast materials and weight win out by a large margin over traditional methods. The traditional method wins on upfront cost by a narrow margin less than $100.

3 Walls: Partial Basement

80 ft × 8 ft = 640 sq ft Total Wall Area

In this example, we are only insulating three outside walls of a basement (measured in the diagram). The floor-to-ceiling height is 8 ft and the total length of the walls to be covered is 80 ft (20 + 40 + 20). Multiplying the total length by the total height (80 × 8), this project requires material that will cover 640 sq ft.

Again, InSoFast materials and weight win by a large margin over traditional methods. The traditional method upfront costs remain cheaper than EX 2.5 panels by about $160, but turn out to be more expensive than UX 2.0 panels by nearly $30.

4 Walls: A Full Basement

140 ft × 8 ft = 1,120 sq ft Total Wall Area

In this example, we are insulating all four walls of a basement (measured in the diagram). The floor-to-ceiling height is 8 ft and the total length of the walls to be covered is 140 ft (30 + 40 + 30 + 40). Multiplying the total length by the total height (140 × 8), this project requires material that will cover 1,120 sq ft.

Again, InSoFast material complexity and weight win by a large margin over traditional methods. The traditional method's upfront costs are now more expensive than both InSoFast panels.
