Superior protection with mineral-based insulation
Rockwool insulation—also known as mineral wool—is a premium solution for homeowners who want long-lasting thermal performance, outstanding fire resistance, and superior soundproofing. Made from natural volcanic rock and recycled materials, rockwool is designed to withstand extreme temperatures while maintaining its insulating properties.
It’s ideal for attics, walls, floors, and ceilings where moisture control and noise reduction are key. Our expert team installs rockwool with precision, ensuring maximum performance and a safer, more comfortable indoor environment.
Why choose rockwool insulation?
Water-repellent and mold-resistant
Unlike other insulation materials, rockwool doesn’t absorb water, making it ideal for moisture-prone areas and resistant to mold growth.
Superior soundproofing
The dense structure of rockwool makes it highly effective at reducing noise between rooms and from outside sources.
Excellent fire resistance
Rockwool insulation can withstand temperatures over 1,800°F, adding an extra layer of fire protection to your home.
FAQs
Where is rockwool insulation typically installed?
It’s great for attics, walls, ceilings, basements, and between floors—especially in spaces where fire resistance and sound control are important.
Is rockwool insulation environmentally friendly?
Yes. It’s made from natural and recycled materials and is fully recyclable at the end of its lifespan.
Does rockwool insulation settle over time?
No. Rockwool retains its shape and density, ensuring consistent performance for decades without sagging or compressing.

EXCELLENT Based on 184 reviews Posted on Google Ollie NicholsTrustindex verifies that the original source of the review is Google. We had no idea why our winter utility expenditures were going up year after year. It came to light that the majority of the attic insulation had settled, and that certain spots had been contaminated by rodents in the past. It was unexpected how much of an impact the replacement had. Now you can forget about fiddling with the thermostat; the temperatures remain steady.Posted on Google Melissa MastersTrustindex verifies that the original source of the review is Google. Basement had this weird cold, damp feeling year-round that never really went away. Mold remediation uncovered moisture trapped behind insulation panels near the wall framing. Everything affected was removed properly and replaced after drying equipment ran for several days. The space finally feels normal instead of clammy.Posted on Google Janice BoissonneaultTrustindex verifies that the original source of the review is Google. Even with the help of candles, the musty smell in the basement persisted. There was growth under storage shelves that we never moved, therefore it was the appropriate call to get rid of the mold. Without resorting to jargon typical of contractors, Evelin kept us apprised of developments. The musty aroma of the cellar has finally dissipated.Posted on Google Tiffany WebbTrustindex verifies that the original source of the review is Google. I expected a few shocks when I bought an older house, but I didn't expect this many. Major maintenance was required in the attic due to polluted insulation and decaying ducting. To ensure that we tackled everything in the correct sequence, Tom provided explicit instructions regarding the priorities. Now the house has a whole new vibe about it.Posted on Google Blake CoxTrustindex verifies that the original source of the review is Google. The attic used to feel extremely hot in summer and freezing in winter. After insulation replacement, temperatures inside the home became much easier to manage. Tomer pointed out several sections where insulation coverage had almost disappeared completely. Wish we had done it sooner.Posted on Google Helen DavisTrustindex verifies that the original source of the review is Google. We prayed it was only noise since we could hear something moving in the garage ceiling. In fact, it wasn't. Insulation cleanup and rodent proofing were the last touches. In order to avoid a similar situation next year, Tom ensured that any susceptible places were locked down.Posted on Google Nannie FarmerTrustindex verifies that the original source of the review is Google. My parents moved in with us. All of a sudden the attic air quality seemed important. There was the problem of rodents from prior years. Tomer’s workers fully cleaned, sealed and reinsulated. The peace of mind was worth every cent.Posted on Google Sue MacDonaldTrustindex verifies that the original source of the review is Google. Attic Star's response time to my inquiry was unbelievable. I emailed requesting an appointment and they called me within 15 minutes. Anytime I have needed to speak with them, and call, an actual person answers the phone. To begin with, that all is a super big plus to me. They sent Jay out to inspect our home and scope out the project to find entry ways for rodents and possible new ways of entry. We were given an estimate, and proceeded to set up an appointment to get the job started. The work crew were great, dependable and did an unbelievable job, closing up entries being used, and closing potential new pathways for rodents. They estimated it would take two days, and that is what it took. We would highly recommend Attic Star to anyone who has problems with rodents. Working with them will give you the confidence your problem has be addressed with excellence and gives you peace of mind.Posted on Google Delores MurakamiTrustindex verifies that the original source of the review is Google. I saw right away that the HVAC system wasn't working properly after purchasing the property from its long-term owners. Yearly accumulation went unnoticed until duct replacement. We were able to correctly update things with Daniel's support.Posted on Google Dora BergerTrustindex verifies that the original source of the review is Google. Holiday hosting made us finally deal with basement mold we’d ignored too long. Tom made that space feel welcoming again.Verified by TrustindexTrustindex verified badge is the Universal Symbol of Trust.

Attic Star did a fantastic job on our attic. Attention to detail, professional, personable, and a clean job, great company. They get all the debris out, clean, close up openings and install insulation. They did not leave any debris in or out of our house. They also take pictures so you can see the results. Highly recommend.
