Proper insulation immediately reduces household energy loss, especially in climates with extreme seasonal swings like Boise. Most homes in the area lose significant energy through uninsulated attics, under-insulated walls, or poorly sealed crawl spaces. Sealing these gaps with spray foam or blown-in insulation blocks heat transfer, stabilizes indoor temperatures, and reduces reliance on HVAC systems.
Homeowners in Boise typically see a 15% to 25% drop in heating and cooling usage after addressing insulation gaps, according to data from the U.S. Department of Energy. This improvement is most noticeable in older homes built before modern energy codes. Nevada Urethane applies field-tested methods backed by on-site experience across a wide range of Boise homes, from ranch-style to split-level constructions.
Boise’s semi-arid climate sees temperature swings from below freezing in winter to highs over 90°F in summer. This variation places continuous pressure on HVAC systems. Insulation acts as a thermal barrier, reducing the work needed to heat or cool the home.
| Feature | Without Proper Insulation | With Updated Insulation |
|---|---|---|
| Annual HVAC Runtime | 2000+ hours/year | ~1400-1600 hours/year |
| Peak Load Strain | High load in summer and winter | Reduced load, extended system life |
| Indoor Temperature Fluctuations | 6-10°F variations daily | 2-4°F variation |
| Utility Bill Impact | 20%-30% higher bills | 15%-25% reduction |

Always check attic insulation depth. In Boise, at least R-49 is recommended for attics. Many homes fall short of this due to settling or outdated materials.
| Area | Recommended R-Value | Common Problem | Suggested Material |
|---|---|---|---|
| Attic | R-49 | Settled fiberglass | Blown-in cellulose |
| Exterior Walls | R-13 to R-21 | Insufficient depth | Closed-cell spray foam |
| Floor/Crawlspace | R-19 to R-30 | Uninsulated cavities | Foam board + spray foam |
| Rim Joists | R-15 | Air leakage points | Closed-cell spray foam |
Homes built before 1990 in Boise often lack continuous insulation and contain thermal breaks at wall junctions, attic hatches, and plumbing penetrations. These weak spots allow conditioned air to escape rapidly. Nevada Urethane’s technicians routinely seal these gaps using a two-step approach: foam injection followed by thermal coating for added durability.
Seal before insulating. Air leaks allow moisture and outside air to bypass insulation altogether. Sealing gaps with foam prior to installing blown-in or batt insulation increases effectiveness by 20%-30%.
Most attic and wall projects in Boise can be completed in 1-2 days depending on size and access.
Only if the existing insulation is dry, mold-free, and not compressing. Otherwise, removal is recommended.
Closed-cell spray foam offers the best performance where air leakage is present. Blown-in cellulose is effective for attics.
Attics: R-49. Walls: R-13 to R-21 depending on construction. Floors: R-19 or higher.
Proper insulation directly impacts comfort, utility usage, and long-term HVAC performance in Boise. Focus on sealing air leaks, verifying material types, and reaching the R-values suited to the local climate.

Every 3-5 years, or immediately after roof leaks, rodent issues, or renovations.
Yes. Blown-in materials may settle 10-20% over 10 years. Periodic checks help maintain performance.
Spray foam can. Fiberglass and cellulose need vapor barriers or sealing to avoid trapping moisture.
Closed-cell spray foam and dense materials provide noticeable sound reduction.
Spray foam requires temporary vacancy due to off-gassing. Blown-in installs are safe with proper containment.
