Proper basement insulation is critical for maintaining energy efficiency, improving indoor comfort, and protecting your home's structural integrity. By reducing heat loss in winter and minimizing heat gain in summer, insulation helps regulate temperatures and can significantly lower your heating and cooling costs.
In addition to thermal benefits, quality insulation helps control moisture, reducing the risk of mold, mildew, and water damage. It also contributes to sound dampening, making your basement quieter and more functional—whether it's used for living space, storage, or recreation.
Investing in basement insulation not only improves daily comfort but also adds long-term value and usability to your home.

Moisture-Resistant Basement Insulation Solutions
Basement insulation is often underestimated—yet it's one of the most critical areas to get right. Traditional materials like fiberglass batts are poorly suited for concrete foundation walls, as they absorb moisture, leading to deterioration, mold growth, and reduced insulation performance.
At Duerst Insulation, we understand the unique challenges of insulating below-grade spaces and provide solutions specifically designed to withstand moisture while maximizing energy efficiency.
Our Recommendation: High-Performance, Moisture-Resistant Insulation
To ensure long-term durability and protection, our top recommendation is closed-cell spray foam insulation, offering a high R-value of 21. This type of insulation not only delivers excellent thermal resistance but also acts as a built-in moisture barrier, helping to prevent mold and maintain consistent indoor temperatures.
Where spray foam may not be suitable, we offer alternative solutions that meet or exceed performance standards, tailored to your home’s specific needs. Ultimately, the goal is to achieve an effective moisture-resistant seal and optimize your home's energy efficiency from the ground up.
Invest in the right insulation—and protect your basement for years to come.
If you're planning to finish your basement, insulating the right areas is critical to achieving a space that’s comfortable, energy-efficient, moisture-resistant, and code-compliant. Here’s a breakdown of the key areas that should be properly insulated:

---|---|---|
Exterior Foundation Walls | Thermal & Moisture Barrier | Closed-cell spray foam / Rigid foam |
Rim Joists / Box Sills | Air Sealing & Insulation | Closed-cell spray foam |
