InSoFast is a brand of advanced, easy-to-install insulation panels that aim to simplify and improve energy-efficient insulation for both residential and commercial buildings. Known for their versatility, high performance and affordability, InSoFast panels offer an innovative solution to traditional insulation. With an emphasis on durability, moisture resistance and energy savings, InSoFast insulation panels have quickly become a favorite among DIY enthusiasts and professionals alike. We spoke with Rachel Siebert, marketing director at Insofast, who provided more detailed insight into the product.

So, What Makes InSoFast Different?
InSoFast panels combine rigid foam insulation with integrated stud framing channels, electrical raceways and moisture management features. The concept is to create an all-in-one solution for insulation, framing and moisture protection, all within a single panel.

"We focus on developing energy-efficient building systems that exceed present and future energy codes, outperform the competition and simplify construction processes," says Siebert. "Insofast is truly a high-performance product."

InSoFast panels offer an impressive R-value, which refers to the material's resistance to heat flow. With a high R-value, the panels enhance the building's thermal efficiency, keeping interiors warmer in winter and cooler in summer.

"Continuous insulation eliminates gaps and thermal bridges, providing consistent R-values and minimizing heat loss or gain through a home or building. By creating a thermal barrier, continuous insulation improves energy efficiency, reduces heating and cooling costs, and enhances overall comfort," explains Siebert.

Other innovations for InSofast include the built-in stud feature and moisture management. Traditional insulation requires separate framing, which can increase costs and installation time. InSoFast panels come with integrated plastic studs, spaced to provide optimal support and insulation, making them ready to receive drywall or other interior finishes without extra steps.

"Arguably the favorite aspect of the panels among contractors or at-home DIY-ers is the ease of installation. The panels come in interlocking tiles, allowing a DIY-er or a professional installer to set them up quickly and accurately," Siebert say. "With built-in studs and channels for electrical wiring it also eliminates the need for more traditional steps, streamlining the entire insulation process and maintaining the integrity of the property."

nSoFast panels also aid assistance in moisture management, essential in basements and other spaces prone to dampness. Siebert further explains that all the panels include a drainage plane on the back, preventing moisture buildup and reducing the risk of mold or mildew.

Simplicity Matters
In a busy world where so many of us are stretched for time, simplicity more than matters, it's greatly appreciated and more often than not sought out.

"Both a skilled professional or a DIY enthusiast can install the self-flashing interlocking insulation panels and expect the same great results," says Siebert. "When using InSoFast you save time on framing, and skip the headache of wiring electrical and HVAC, because our panels can be simply and quickly applied directly over the cold walls of a basement. In fact, in can be installed four times faster than other products."

To cater to different applications and performance requirements, InSoFast offers various panel types; including the Flat Panel UX 2.0, the thinnest profile flat panel, optimized for insulating interior surfaces and is versatile enough for use on floors, walls, ceilings and can be adapted for framed wall construction or other unique conditions. It's also a good choice as a sub-flooring base panel and for shipping container builds.

The Flat Panel EXi 2.5 is the most versatile interior and exterior grade panel, as it is optimized for masonry, flat surfaces or framed construction. It combines all the best features of continuous insulation and is ready for finishing.

Lastly, the thickest panel yet, the MAX 3.75 RW is a 3¾ inch, thick closed-cell, injection-molded EPS foam panel that achieves an impressive R-15.9 insulation. The MAX 3.75 RW is a universal super-insulated flat panel, optimized for interior and exterior finishes. "This panel is particularly popular for use in basements or ground floors where cold concrete can impact overall comfort," Seibert says.

InSoFast panels have redefined the standard for insulated wall construction, delivering superior energy efficiency, reduced installation time and cost savings. Their innovative design and wide applicability make them a smart choice for modern builders, architects and property owners. As energy efficiency and green building practices continue to gain importance, solutions like InSoFast panels are set to play an increasingly critical role in sustainable construction.
