Hybrid Insulation in Oregon
A closed-cell base layer paired with a second insulation type to hit target R-values at lower cost.
Hybrid Insulation
Want the benefits of spray foam insulation but on a budget? Our Hybrid insulation might be the answer.
The cost of a full coating of spray foam can be 3-4x the price of traditional insulation. For residential builds, this might be seen as too much, so we offer a hybrid insulation method that gives you the benefits of our Closed Cell spray foam, but at a fraction of the cost.
Our hybrid insulation is the most cost-effective way to get your home to code incorporating spray foam. We start by applying a 2-inch layer of our Closed-Cell spray foam. This provides a continuous moisture barrier; spray foam has no seams or joins so eliminates entrance points for moisture and damp. When applied to exterior walls or in attic spaces it creates an airtight space; meaning heating and cooling your home will be cheaper than before.
After the layer of closed-cell spray foam has been applied, we then fill the remaining space with wither fiberglass or open-cell spray foam, which increases the R rating of your home. Fiberglass is a cheaper option, but open-cell provides better acoustic insulation. Get in touch today, we’ll be happy to discuss the options and find one that works for you.
As a qualified Energy Trust of Oregon Trade Ally, we provide savings to our customers through qualified rebates from the Energy Trust of Oregon. Find out if you’re eligible.
Hybrid insulation is a method that combines two types of insulation—typically closed-cell spray foam and fiberglass or cellulose —to maximize energy efficiency, cost-effectiveness, and overall performance.
Why it can cost less
Hybrid insulation offers the benefits of both spray foam and traditional insulation, including:
Superior Air Sealing: Closed-cell foam prevents air leaks, while fiberglass/cellulose boosts thermal insulation.
Moisture Resistance: Spray foam acts as a vapor barrier, reducing condensation and mold risks.
A thin layer of closed-cell spray foam (1–2 inches) is applied first to provide an airtight seal and moisture barrier. Then, fiberglass batts or blown-in cellulose are added to increase R-value and reduce costs.
The spray foam layer stops air leakage and moisture infiltration, while the fiberglass or cellulose layer increases the overall R-value, reducing heating and cooling costs.
Yes! By using less spray foam and incorporating traditional insulation, hybrid insulation provides excellent performance at a lower cost than full spray foam systems.

Common Questions
Is hybrid insulation a good fit for Eugene-area buildings?
Yes. Hybrid Insulation works well for many Eugene-area homes and commercial buildings, but the right choice depends on the space, the assembly and how it is used. During a free estimate we confirm whether hybrid insulation or another option fits your building.
How much does hybrid insulation cost?
Cost depends on the area being treated, the material and thickness, access and prep. Estimates are free and given in writing, so you know the price before any work begins.
How long does a hybrid insulation project take?
Most projects are completed quickly once scheduled. Your written estimate includes the expected timeline for your specific Eugene-area project.
