Industry insights, installation tips, product updates, and news for professional spray foam contractors.
In-depth guides on spray foam insulation, costs, comparisons, and best practices from the ThermoSeal USA team.
The federal 25C insulation credit ended for installations after December 31, 2025. What that means for 2026 projects, how to still claim a 2025 install, and the state and utility incentives that remain.
HFO-blown closed cell foam delivers R-7.4 per inch and a GWP of 1, compared to R-6.5 and a GWP of 1,030 for HFC-blown products. Here's what the difference means for your project and why HFO is the future of closed cell insulation.
The crawl space is the most moisture-prone part of any home, and the place where product choice matters most. Here's why closed cell is almost always the right answer and how to approach the assembly correctly.
The right attic spray foam thickness depends on your IECC climate zone and the product you use. This guide covers code minimums, required thickness for every ThermoSeal product, and attic floor vs. roofdeck considerations.
The math behind spray foam ROI: average project costs, annual energy savings, payback period calculations, and the factors that accelerate or slow your break-even point.
Average installed costs by foam type and application zone, what drives the price, how spray foam compares to fiberglass on total cost, and how to evaluate any quote you receive.
Why R-value alone doesn't tell the whole story, where fiberglass still makes sense, and where spray foam wins decisively, including crawlspaces, roofdecks, and metal buildings.
R-values, vapor permeability, moisture resistance, structural contribution, and the best application for each foam type, including a full side-by-side comparison table.
