Frequently Asked Questions About Spray Foam & Stucco

Making the right choice for your home, farm, or business is a big deal. We want you to feel completely confident in your investment. Below, we answer the most common questions we get about our insulation and exterior services in Minnesota, North Dakota, and Wisconsin.

Spray Foam Insulation Questions

Is spray foam really better than traditional fiberglass?

Yes, spray foam is highly superior to traditional fiberglass. While fiberglass can sag over time and easily allows air to pass right through it, our spray foam expands to fill every tiny crack and gap in your walls.

This creates a permanent, airtight seal that stops cold drafts and massive heat loss. Because it holds its shape and provides a much higher R-value (insulation rating), it keeps your monthly utility bills drastically lower for the lifetime of your building.

Does spray foam add structural strength to my building?

Closed-cell spray foam does indeed add structural strength to your walls and roof. When it cures, it becomes completely rigid, strongly tying the exterior sheathing and wooden framing together.

This is a massive benefit for our agricultural and commercial clients who own large pole barns or metal buildings. It helps the structure handle heavy Minnesota snow loads and strong winds much better than empty wall cavities.

Will mice and pests eat through the spray foam?

No, mice and other rodents do not eat spray foam because it holds zero nutritional value for them. Even better, pests are usually drawn into a building because they can feel the warm air leaking out through small exterior gaps.

Because our spray foam creates a complete airtight seal, rodents cannot feel the heat escaping, which means they are much less likely to try and get inside your home or barn in the first place.

How long does the installation process take, and is it safe?

Most of our residential and commercial spray foam jobs can be finished in just a day or two. During the actual spraying process, we ask that you and your pets leave the immediate area for safety.

The foam cures very quickly, and the space is completely safe to re-enter and live in within 24 hours. We use high-quality, industry-approved materials that will safely protect your building without leaving a lingering smell.

Stucco and Outsulation Questions

What exactly is exterior outsulation?
Outsulation is a modern, highly efficient way to finish the outside of your building. Instead of just attaching standard siding directly over your wood frame, we first wrap the entire outside of your building in a continuous layer of high-quality insulation. Then, RW Stucco applies a beautiful, durable stucco finish right over that insulation.
This specialized system stops heat from escaping through your wooden wall studs, saving you a huge amount of money on heating and cooling.
How long will a new stucco exterior last?
When properly installed by our expert team, your new stucco exterior can easily last 50 to 80 years, or even a lifetime. We use premium materials specifically designed to handle the extreme freezing and thawing cycles of the midwest. Because the finish is so durable and weather-resistant, it acts as a long-term, maintenance-free shield for your property.
Will my new stucco crack over time?
All cement-based products can develop tiny hairline cracks as a building naturally settles into the ground over the years. However, we take strict extra steps to prevent this. We use specialized finishes and an engineered application process that gives the stucco the flexibility to bridge those small movements. This keeps the exterior looking smooth, beautiful, and completely water-tight for decades.
Is stucco a good choice for my commercial or agricultural building?
Absolutely. Upgrading to a stucco exterior is one of the smartest investments a business or farm owner can make. It gives your property a clean, high-end, professional look while simultaneously lowering your overhead energy costs through our outsulation process. It is incredibly tough, fire-resistant, and requires almost no maintenance compared to painting wood siding or replacing dented steel panels.
