At Go Green Insulation, we know that summers in the Pacific Northwest may be known for their mild beginnings, but recent climate shifts have pushed temperatures higher each year. From Boise to Bend, homeowners are experiencing more intense and prolonged heat waves. While air conditioning might be the go-to response for many, the true long-term solution lies in something much simpler: insulation. Proper insulation isn’t just for staying warm in winter—it plays a critical role in keeping your home cool, reducing energy bills, and maintaining comfort all summer long.
Why Insulation Works for Hot Weather, Too
Insulation acts as a thermal barrier, slowing down the transfer of heat between the outdoors and your home’s interior. In summer, this means it keeps hot air out and the cool air inside. Without sufficient insulation, your home heats up faster, forcing your AC to work harder and less efficiently.
Here’s how insulation helps in summer:
Reduces indoor heat gain: Prevents sun-exposed areas like attics and walls from radiating heat inward.
Supports HVAC performance: Maintains consistent temperatures so your cooling system doesn’t overwork.
Lowers cooling costs: Reduces the need for prolonged air conditioning use.
Increases indoor comfort: Keeps indoor temperatures stable, even during peak afternoon heat.
According to the U.S. Department of Energy, homeowners can save up to 15% on heating and cooling costs by properly insulating their homes, including attics, crawl spaces, and walls.
Summer Insulation Tips for Homeowners in Idaho and Oregon
If you’re preparing your home for another hot Pacific Northwest summer, start with these insulation strategies:
Upgrade attic insulation: Hot air rises and accumulates in the attic. Spray foam or blown-in cellulose can create a barrier against extreme roof temperatures.
Seal air leaks: Tiny gaps around windows, doors, and plumbing can allow warm air to enter. Sealing these areas complements insulation and boosts efficiency.
Consider spray foam insulation: Spray foam offers superior air sealing and thermal resistance, making it ideal for both new homes and retrofits.
Focus on sun-exposed walls: South- and west-facing walls absorb the most heat. Ensuring these areas are well-insulated can drastically reduce indoor heat gain.
Check for insulation gaps: Common problem areas include basements, knee walls, and overhangs. An energy audit can pinpoint where insulation may be lacking.
In older homes across Idaho and Oregon, it’s not uncommon to find outdated insulation or areas where insulation was never installed. A professional inspection from a trusted regional provider can reveal where improvements are needed most.
How Spray Foam Insulation Maximizes Cooling Power
Among the many insulation options available, spray foam stands out for its dual function: it insulates and air-seals at the same time. This makes it particularly effective in high-temperature months. Closed-cell spray foam, for instance, has an R-value of approximately 6.5 per inch—higher than most other types of insulation. The higher the R-value, the better the resistance to heat flow.
Benefits of spray foam cooling include:
Air-tight barrier: Blocks hot air and moisture infiltration
Moisture control: Prevents mold and humidity buildup
Structural reinforcement: Adds strength to walls and roofing areas
Longevity: Maintains thermal performance over decades without settling
Because of its comprehensive coverage and resistance to air leakage, spray foam is an increasingly popular choice for homeowners in Boise, Portland, and surrounding communities looking to enhance summer comfort and energy efficiency.
Thinking About an Energy-Efficient Home?
An energy-efficient home isn’t just about saving on monthly bills—it’s about increasing overall quality of life. Insulation plays a foundational role in creating a home that stays cool in summer, warm in winter, and comfortable year-round. Additionally, many homeowners may qualify for energy rebates and tax incentives when upgrading insulation, particularly with high-efficiency materials like spray foam.
Key takeaways for boosting summer efficiency:
- Evaluate attic and wall insulation before peak heat hits
- Choose high-performance products like closed-cell spray foam
- Work with certified local insulation experts who understand Northwest climate patterns
Go Green Insulation serves homeowners throughout Idaho and Oregon, offering personalized insulation strategies that fit your home’s structure, age, and energy needs.
Wondering What to Expect When Upgrading Your Insulation?
Here are some common questions we get from Pacific Northwest homeowners:
How long does it take to install spray foam insulation?
Most single-family homes can be completed in one to two days, depending on the areas being treated.
Is spray foam safe for homes with children or pets?
Yes. After a short curing period (typically 24 hours), spray foam is fully safe and stable for all residents.
Can insulation really help reduce cooling costs?
Absolutely. A well-insulated home can reduce cooling expenses by as much as 20% during summer.
What makes spray foam better than fiberglass in hot weather?
Spray foam forms a continuous air seal, whereas fiberglass can leave gaps that allow hot air to seep through.
Does insulation help with humidity?
Yes, especially closed-cell spray foam, which resists moisture and helps reduce indoor humidity levels.
Summer Insulation Checklist
Before temperatures rise, make sure your home is ready:
- Inspect attic insulation levels
- Seal air leaks in ducts, doors, and windows
- Insulate crawl spaces and rim joists
- Choose spray foam for superior cooling and sealing
- Schedule a home energy evaluation with a trusted pro
