1. Superior Insulation Performance in Extreme high and low temperatures
North Idaho’s winters and summers can be brutal, with temperatures regularly dipping below freezing in the winter and temperatures well into the triple digits in the summer.
Spray foam insulation provides a much higher R-value per inch than fiberglass. The R-value is a measure of an insulation material's effectiveness at resisting heat flow. Since spray foam expands to fill gaps and cracks, it creates an airtight seal that prevents cold and warm air from infiltrating and conditioned air from escaping. Fiberglass, on the other hand, doesn’t expand to seal gaps, so it can leave spaces where air can leak in, reducing its effectiveness in extremely cold and warm climates.
Why it matters for your shop: Keeping your shop warm in the winter and cool in the summer is critical to both comfort and energy savings. Spray foam’s ability to seal out the hot and cold means you can keep the temperature more stable, reducing the need for constant heating and/or cooling.
2. Energy Efficiency and Lower Heating/cooling Costs
In a region like North Idaho, where heating costs can skyrocket during long winters, energy efficiency is key. Spray foam insulation has superior air sealing properties, which means it prevents heat from escaping and keeps the cold air outside. Fiberglass insulation, by comparison, can allow air to pass through gaps and seams in the material, leading to higher energy bills. And in the summer, it can keep your shop at a consistent temperature which is more enjoyable to work in.
Why it matters for your shop: With spray foam, your shop will retain heat and coolness better, meaning you won’t need to run your heater, or as often. Shops will retain a nice cool temperture in the summer which this translates to significant savings on your energy bills over time. With fiberglass, you might end up paying more to maintain a comfortable temperature because of the air leaks.
3. Moisture and Mold Resistance
The weather in North Idaho can be unpredictable, with lots of snow and rain, which can lead to moisture problems in buildings. Spray foam insulation acts as both an air and moisture barrier, helping to prevent the build-up of condensation, which can lead to mold, mildew, and structural damage. Fiberglass insulation, however, is porous and can trap moisture, making it susceptible to mold growth if the insulation becomes wet.
Why it matters for your shop: Moisture control is crucial for maintaining the integrity of your shop’s structure and keeping a healthy working environment. With spray foam, you're less likely to experience mold problems, which is especially important if you store equipment, materials, or tools that can be damaged by humidity.
4. Long-Term Durability
Spray foam doesn’t sag or settle over time. Once it’s sprayed and cured, it remains effective for the life of the building. In contrast, fiberglass can deteriorate, compress, or lose its insulating properties over time, especially if it becomes wet. The performance of fiberglass can also degrade due to settling or shifts in the building’s structure, leading to gaps and reduced efficiency.
Why it matters for your shop: You don’t want to have to worry about replacing insulation or dealing with areas of reduced efficiency over time. Spray foam will continue to provide high performance for decades, while fiberglass might need to be replaced or adjusted periodically.
5. Air Sealing and Comfort
Air leakage is a huge factor in maintaining comfort, especially in a large shop space. Spray foam expands as it is applied, filling every crack, crevice, and gap. This means that even hard-to-reach places like around windows, doors, and pipes are sealed up. Fiberglass doesn’t expand, so it can leave gaps around these areas, leading to drafts and uneven temperatures throughout the building.
Why it matters for your shop: When your shop is properly sealed with spray foam, you’re less likely to deal with drafts, cold spots, or areas that are harder to heat. This leads to a more comfortable working environment year-round.
6. Noise Reduction
If you’re running a busy shop, noise control may be important. Spray foam has excellent soundproofing properties due to its density and ability to expand into cracks. It absorbs sound and reduces the transfer of noise between rooms or through walls. Fiberglass, on the other hand, doesn’t provide as much soundproofing unless it’s specifically designed for noise reduction.
Why it matters for your shop: Whether you're working with loud machinery, power tools, or just need a quieter environment for concentration, spray foam helps keep the noise inside the shop contained, preventing it from disturbing the outside or neighboring businesses.
7. Ease of Installation
When you're running a shop, you need insulation that gets the job done quickly with minimal disruption. Spray foam insulation can be installed much faster than fiberglass. Since spray foam is applied as a liquid, it expands to fill all gaps, cracks, and voids, making the installation process quicker. Fiberglass insulation, on the other hand, requires careful fitting between studs, joists, and beams, and may still leave small gaps that compromise the insulation's effectiveness.
Why it matters for your shop: Minimizing downtime is important for your business. Spray foam installation is typically faster and more efficient, meaning less disruption to your shop operations.
8. Increased Property Value
Buildings with high-quality insulation, like spray foam, are more energy-efficient and comfortable, which increases their resale or rental value. This is especially true in regions like North Idaho, where energy efficiency is highly valued. Fiberglass, while still an option, may not provide the same long-term value as spray foam due to its lesser performance in extreme conditions.
Why it matters for your shop: If you plan on selling or renting your building in the future, having spray foam insulation could be a selling point that adds value to your property.
Conclusion: Spray Foam vs. Fiberglass in North Idaho
In North Idaho, where winter temperatures can be extreme and moisture can wreak havoc on buildings, spray foam insulation is simply the better choice for shop buildings. It outperforms fiberglass in nearly every category, from energy efficiency and moisture control to comfort and durability. For shop owners looking to protect their investments, reduce energy costs, and create a more comfortable and efficient workspace, spray foam is a long-term solution that will pay off.
