Closed-Cell Insulation in Oregon
High-density closed-cell foam that adds R-value, structural rigidity and a moisture barrier in one application.
Closed-Cell Insulation
Premier Spray Foam Insulation's high performance closed-cell spray polyurethane foam is MORE than just insulation.
Foam insulation is an alternative to more traditional insulation products such as bead and wool. Foam insulation is often chosen because it offers a greater level of insulation meaning it cuts energy costs and utility bills. Foam insulation also offers great noise reduction qualities as the foam doesn’t allow as much noise to travel through as traditional forms of insulation.
There are two types of foam insulation; open cell or closed cell foam insulation. The description “closed-cell” comes from the structure of the insulation material. Because of this structure, closed cell foam insulation will not absorb water and will prevent moisture from getting through the cavity to the inside of the property. Closed cell foam insulation can be used in both the roof and the cavity wall of a domestic property as well as in commercial and industrial buildings such as offices or warehouse. It is also a durable air barrier material that provides moisture resistance and strengthens your home.
Closed-cell spray foam insulation is one of the most efficient insulating materials commercially available, with R-Values above 6.0 per inch.
Higher R-value* per inch – easier to accommodate high R-value* requirements in narrow spaces

Performance and where it fits
Spray foam roofing insulation is a seamless, durable, and energy-efficient solution that helps protect and insulate your roof. It consists of a liquid foam that expands to create a solid, waterproof barrier.
The foam is applied as a liquid, which expands and hardens into a protective layer. This helps prevent heat loss, reduces energy costs, and provides an extra layer of waterproofing.
Installation time depends on the size of the roof, but most projects can be completed within a few days.
Yes, but minimal. We recommend regular inspections and reapplying a protective coating every 10-15 years to extend the lifespan.
Yes! Spray foam can be applied over many existing roof materials, reducing the need for a full roof replacement.
Yes! Small damages can be easily repaired with sealant or additional foam applications.

Common Questions
Is closed-cell insulation right for my building?
It depends on the assembly, how the space is used and what problem you are trying to solve. We confirm that on site during a free estimate rather than guessing from a phone call, and we will tell you if a different option suits the building better.
How much does closed-cell insulation cost?
Cost depends on the area 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 the work take?
Most projects are completed quickly once scheduled. Your written estimate includes the expected timeline for your building.
Do you work across Oregon?
Yes. We install statewide, from the coast through the Willamette Valley to Central and Southern Oregon. Conditions differ across those regions and the right specification changes with them.
