You probably have questions and we have anwsers

Here are some of our most frequently asked questions

What happens to the air flow?​

SPF acts as an excellent air barrier, sealing gaps, cracks, and voids in the building envelope. It expands and fills in hard-to-reach areas, creating a continuous insulation layer that prevents air infiltration and reduces energy loss. Fiberglass insulation, on the other hand, can leave gaps and allow air leakage if not properly installed and sealed.​

What about moisture?​

SPF is resistant to moisture and can help prevent water infiltration and condensation within the building. It can form a seamless, monolithic barrier that reduces the risk of mold growth and protects against moisture-related issues. Fiberglass insulation, if not properly installed or if it gets wet, can lose its insulating properties and may promote mold growth.​

Improved sound insulation

SPF has good sound-dampening properties, reducing noise transmission through walls and floors. It can effectively minimize sound transfer and create a quieter indoor environment compared to fiberglass insulation

Where can it be applied? Why is it better than other forms of insulation?

SPF can be applied in various forms, including open-cell and closed-cell foam, allowing for greater versatility in insulation projects. It can conform to irregular surfaces, filling cavities completely, and adhering to different materials. Fiberglass insulation comes in pre-cut batts or rolls, limiting its application to standard-sized spaces and requiring careful installation to avoid gaps.

What is the cost comparison?

One downside to SPF is that is costs significantly more upfront than fiberglass. These costs can be recouped over time through energy savings and in this regard it can be helpful to think of SPF as an investment. A typical house going from fiberglass to SPF often makes up the difference of cost in as little as 5 years. Any savings beyond the breakeven point is money in your pocket, for as long as you live in your home.

An extra note:

It's worth noting that both SPF and fiberglass insulation have their specific uses and advantages depending on the requirements of the project. Factors such as budget, climate, building design, and personal preferences should be considered when choosing the appropriate insulation material. Consulting with a professional insulation contractor can provide further guidance based on your specific needs.

What We Offer

Closed Cell Spray Polyurethane Foam

Closed cell foam is the highest performance insulation material on the market today. It is extremely energy efficient, and provides superior comfort in a home. It can also provide increased air quality inside a home by creating an air seal. Closed cell foam also adds structural strength to whatever building it is applied to.

Open Cell Spray Polyurethane Foam

Open cell foam is not used much in our climate zone in Western Montana but can be used in certain applications such as extra R value for cheaper on top of a layer of closed cell or sounding between floors.

Mineral Wool

Mineral wool also known as rock wool gives far superior sound deadening performance compared to fiberglass. It is used in many commercial and residential buildings for sound and fire control.

Fiberglass Blow In

Blown Fiberglass is used in applications like attics (loose fill) or walls (blown in blanket) in order to provide superior thermal control compared to batts. Since it is blown in, it can fill and conform to odd shaped and small places. This extra coverage and easy lack of gaps makes it a great alternative to fiberglass batts even when other options like foam are too expensive.

Fiberglass Batts

This is our base material and will be your cheapest option to install if your budget is tight. We use this product for sounding interior walls as well as insulating exterior walls. Even though there are more energy efficient insulation materials on the market we still see a number of houses built with fiberglass batts.

Blown Cellulose

Blown cellulose can offer superior sound dampening with increased R value compared to fiberglass. Superior insulating properties: SPF has a higher R-value per inch compared to fiberglass insulation. R-value is a measure of thermal resistance, and a higher R-value indicates better insulation. SPF can provide a higher level of insulation with less material thickness, allowing for more efficient use of space.
