Cellulose Attic Insulation
What You Need To Know
When it comes to attic insulation, choosing the right material can significantly impact your home’s energy efficiency and comfort. We trust Owens Corning, the #1 most trusted brand of insulation*. Let’s explore cellulose insulation and why Owens Corning PROPINK L77 stands out as a preferred choice.
What is Cellulose Insulation
Cellulose insulation is a home insulation made from recycled paper products, primarily newspapers. It’s treated with fire retardants to enhance safety and is installed by blowing it into attics and wall cavities. Despite being environmentally friendly due to its use of recycled materials, cellulose insulation may not be the best choice for home efficiency. It can settle over time, reducing its insulating effectiveness and creating gaps that allow air leakage. Additionally, cellulose can absorb moisture, leading to mold growth and compromising its insulating properties. This moisture absorption can also contribute to the deterioration of building materials, potentially leading to costly repairs. Consequently, homeowners might experience higher energy bills and increased maintenance costs when using cellulose insulation.

Owens Corning PROPINK L77
Owens Corning PROPINK L77 is a high-performance loose-fill fiberglass insulation designed to deliver outstanding thermal efficiency. Unlike cellulose, PROPINK L77 offers consistent coverage without settling over time, ensuring long-lasting performance. Its unique composition allows for easy installation, making it ideal for both new construction and retrofit projects.
- Excellent thermal and acoustical performance

Kudos to this amazing company! Their honesty and integrity is a rare find these days. I highly, highly recommend this company!
Brian, the owner, is a sincere man who genuinely cares about his work and the reputation of his company. This is a rare quality in the field. Many contractors promise the world but underdeliver. Brian and his team are different. They're not only friendly and professional, but they also hold themselves to high standards. If something isn't right, they fix it until the customer is satisfied.
Recently, I needed to replace the insulation in my attic—a challenging job, especially in the heat. I received several quotes, but Zhe Industries offered a reasonable rate and a clear explanation of the work. They delivered exactly as promised. The team efficiently removed the old insulation, sanitized the attic, sealed gaps and cracks, and installed new insulation, following all codes meticulously.
Encouraged by their performance, I trusted them with replacing my roof's missing drip edge and the gutters. We agreed on terms and they got to work. After they finished, I noticed a few minor issues. I brought these up and Brian personally addressed them immediately, apologizing for the oversight.
Finding a trustworthy contractor can be daunting, but Zhe Industries has proven to be a reliable choice in the Hampton Roads area. They truly take pride in their work, and it shows.
We had Zhe Industries insulate and air seal our attic around mid June and it has been unbelievable how good of an investment this was. I'm not certain we'll see much in savings this year as our AC pretty much runs full stop from morning until later in the evening but it is much more comfortable.
Another huge added bonus for us was the noise deadening. Since we had so little insulation or none in our attic in the first place it basically acted like a guitar and we could hear every noise from outside. We also live under the Oceana flight path so there's tons of jets flying throughout the week at all hours. Since we now have much more insulation and coverage than before outside noise has probably dropped by at least 60 to 70 percent. Even the jets don't over power indoor conversations and we can barely hear when people are mowing their lawns.
The crew were polite and very professional. It took about half a day to remove the old insulation and install the baffles and then a short hour or so for them to blow in the new insulation.
Overall very satisfied and would highly recommend their services.
Your House as a System
Though insulation is one of the most essential and cost-effective ways to create overall efficiency, there are many factors to take into consideration. Insulation and air sealing combined with energy-efficient appliances, windows, doors, lighting and HVAC equipment build a whole-house efficiency system that will prove beneficial throughout the year and for years to come. We can provide an in-home consultation to help you create a plan to address any energy concerns in your household.
