The word acid is often associated with harm or danger⚠️, however! Some acids have very helpful properties, such as fire🔥, mold, and pest resistance. One of these types of acids is boric acid, which is in our premium cellulose insulation. What is boric acid, though, and why do we include it in our insulation? For more of an overview on boric acid, watch our building science video with Bob👨‍🔬!

With the warmer weather upon us🔥🔥, keeping your home cool is essential. Insulation isn't just needed for the winter months; it's vital for the summer months, too! However, many homes are not well enough insulated to beat the summer heat. Traditional insulation materials like fiberglass can often leave gaps and air pockets, which can lead to rooms being drafty in the winter and uncomfortably hot in the summer. With the rising costs of energy bills, it's essential that the air you spend money on stays in your home.

❄️Nu-Wool Premium Cellulose Insulation, on the other hand, is the true hero your home and wallet need this summer. Because of its high installed density, Nu-Wool Premium Cellulose Insulation eliminates voids and air pockets and creates a solid barrier that resists airflow. This effectively seals your home and keeps the heavy, humid summer heat outside while trapping your refreshing, air-conditioned air indoors. By stopping your AC from working overtime in the summer, Nu-Wool can help lower energy bills by providing a consistently conditioned and comfortable home all summer long.

We often see the same misconceptions about cellulose circulating online. Many claim, “Cellulose is made of paper, so it’s a fire hazard.🔥” In reality, the opposite is true. Nu-Wool Premium Cellulose Insulation carries a Class A fire resistance rating and even outperforms mineral wool in critical fire-safety tests.

✅Our insulation is treated with borates, which provide exceptional fire resistance. Furthermore, the high density of our professional installation restricts oxygen flow, significantly slowing the spread of flames. In the event of a fire, Nu-Wool creates a protective char layer along the burning areas to act as a barrier. This increased burn-through time provides those extra, life-saving minutes when they matter most.

‼️We also offer a variety of UL-classified firewall designs, including our UL-U382. This full load-bearing design is ideal for multi-family residential structures, providing up to three hours of fire protection.

👀Still skeptical? Head over to our YouTube channel, NuWoolCo, to watch our burn test video. You’ll see Nu-Wool Premium Cellulose go head-to-head with the industry’s most common alternatives. See the performance for yourself!
