Great Product

Worked great

Awesome. Annoying to have to buy bulk orders from major retailers. Simple and easy.

Great delivery. Ty

We put this in exposed floor areas and love how quiet the house feels now. Plus, it adds a bit of fire protection.

We used it in our recording studio. It made a huge difference. Fire safety was a nice bonus, but the soundproofing sold us.

I was skeptical at first, but after using it in my duplex, I’m impressed. Tenants report way less noise from neighbors.

First time using stone wool, and I’m hooked. I especially liked how easy it was to shape without much dust or mess.

What drew me in was the sustainability aspect—basalt and slag. What kept me loyal was the performance. Worth every penny.

This stuff is next-level. Rock-based fibers hold up well in humid environments. It hasn’t sagged or absorbed moisture at all.

As a contractor, I recommend this to all my clients. Great quality, easy to work with, and top-notch performance.

Great for DIYers. It cuts easily with a serrated knife and doesn’t produce much mess. Big fan of the performance too.

We live in a cold climate and added this to our exterior walls. The difference in warmth is noticeable. Highly recommend.

This batt is very user-friendly for DIY projects. It fits well without gaps and greatly improved my home’s heating and cooling efficiency.

I’m a first-time DIYer and found Safe’n’Sound easy to install. Fits right in without hassle and really blocks out sound.

This were very helpful

We put this in our nursery and it’s been perfect. Less noise and more peace of mind with its fire-resistant properties.

Very impressed with how easy it was to install in wall cavities. It’s denser than fiberglass, making it more effective.

Cut and shaped easily, plus it holds firm in place. I used it in a pitched roof application and it's working great.

Very happy with Rockwool’s performance. Easy to handle and install. The material feels solid and insulates like a champ. I love the eco-conscious formula.

Our home feels safer and more comfortable since installing Safe'n'Sound. I recommend it for anyone needing fire and sound protection.

I’m impressed with the quality and performance of Safe'n'Sound. The peace of mind knowing it won’t catch fire easily is priceless.

I used it between bedrooms in our new home. It’s made a huge difference—no more hearing the TV from the other room.

Easy to work with and noticeably quieter throughout the house. Also love that it’s fire resistant—peace of mind is priceless.

Absolutely love it! Not only does it perform great, but it also feels much more eco-conscious than foam or fiberglass.

Safe'n'Sound really made a difference in our home’s noise level. It’s easy to install and gives great fire protection. Highly recommend!

Used this for our basement renovation. The soundproofing is amazing, and it feels good knowing it’s non-toxic and fire safe.

Used it between steel studs and it worked beautifully. Very dense and fits tight. I'm impressed with the acoustic benefits too.

Easy to install and really effective! I used this in attic spaces and immediately felt the difference in sound and temperature control.

Love that it’s non-combustible. I sleep better knowing we’ve added a layer of fire safety, and the quiet is just an added bonus.

Used on above-grade walls during a renovation. It keeps the house noticeably warmer and blocks out a lot of noise too.

This board was exactly what I needed for my above-grade walls. It’s strong, easy to cut, and fits snugly without gaps.

This stuff is built to last. I used it in a renovation five years ago and it hasn’t moved or degraded at all.

No dust, no mess. Easy to cut and install. Worth every penny if you want a safe and durable material.

I recommend Safe'n'Sound to friends and family. It works well, is environmentally friendly, and adds an extra layer of safety.

It was worth every penny. My home feels more peaceful, and I feel safer knowing this is in the walls.

As a mom of two toddlers, I needed something to keep the noise down between rooms. This stuff really works and makes my home feel more peaceful.
