Insulation Guides
What we have learned installing spray foam in Oregon homes, shops, barns and breweries.
Guides from Oregon Jobs
Written from work we have actually done: roof decks on the coast, crawl spaces in the valley, farm buildings and grow facilities.
- A Return On Your Insulation Investment
How an insulation project pays back in an Oregon building, and why the honest answer depends on the envelope and the equipment.
- Agricultural Farm Insulation - Why Closed-Cell Spray Foam Insulation is Perfect
Why closed-cell spray foam suits Oregon farm buildings, and how it stops condensation forming on a metal shell.
- Eco-Friendly Insulation
The environmental side of spray foam: what the blowing agents do, and where the efficiency gain offsets the material.
- Examples of Bad Spray Foam Applicators and Why You Should Choose the Right Insulation Contractor
Photographs of Oregon spray foam jobs that went wrong, what failed in each, and the questions to ask before you hire.
- Fully Insulated Building Envelope
What a building envelope is, why sealing it matters as much as insulating it, and where Oregon buildings usually leak.
- How Is Polyurethane Closed-Cell Spray Foam Insulation Different From Traditional Insulation?
How closed-cell spray foam differs from fiberglass and cellulose, and the conditions where that difference actually matters.
- How To Choose The Best Insulation Type
How to choose between open-cell, closed-cell and traditional insulation for an Oregon building, and what drives the decision.
- Industrial Grade Dehumidifier
Controlling moisture in a large Oregon building, and why insulation and dehumidification solve different halves of the problem.
- Merry Christmas and a Happy New Year
A seasonal thank you from the Premier Spray Foam crew to customers across Oregon, and the work we cover year round.
- Superior Insulation Choice why it is Spray Foam Insulation
Why we specify spray foam over fiberglass and cellulose, what it costs more to do, and where the extra spend pays back.
- The Cost of Re-installing Spray Foam Insulation
What it costs to put a thin spray foam install right, and why 2 inches on a roof deck is a false economy in this climate.
- The Difference Between Open-Cell & Closed-Cell Spray Foam Insulation
Open-cell against closed-cell spray foam: where each belongs in an Oregon building, and how to tell which one you need.
- What is an R-Value & Why Does it Matter?
What R-value actually measures, why it is not the whole story, and how it trades against moisture control in an Oregon assembly.
- Why Polyurethane Closed-Cell Spray Foam Insulation Is Good For Your Indoor Cannabis Grow Farms
Insulating an indoor grow facility in Oregon: humidity control, condensation on the shell, and why closed-cell suits the job.
- Why Your Brewery on the Oregon Coast Needs Spray Foam Insulation
Why a brewery or any building on the Oregon coast needs a different insulation specification from one inland.
- Your Roof Deck Needs 3 Inches of Closed-Cell Spray Foam Insulation, and This Is Why
Why we specify 3 inches of closed-cell on a Pacific Northwest roof deck, and what 2 inches leaves exposed to condensation.
Common Questions
Who writes these guides?
They come from Premier Spray Foam Co's own field experience installing spray foam across Oregon, covering the conditions and assemblies the crews actually encounter.
Do these guides apply outside Oregon?
The physics does. The specifications often do not. Much of what is written here is tuned to a long damp heating season and to Pacific Northwest roof assemblies.
Where should I start?
If you are specifying a roof deck, start with why we recommend three inches of closed-cell. If you are choosing between materials, start with open-cell against closed-cell.
