Have you ever been in one bedroom or bathroom in your house and heard noises from another room? As you can imagine, the sound of a flushing toilet or other objectionable noise can be very embarrassing. Failing to properly soundproof interior rooms of a home is one of the biggest mistakes made in new home construction. Just ask anyone who has experienced a loud houseguest.

If you are looking to resolve the noise problems in your home, help is on the way. A new Roxul stone wool insulation manufacturing facility is opening in Byhalia, Miss., later this year.

Stone insulation is a product derived from melting natural basalt rock, recycled slag and coke to 2732°F, and then spinning wool fibers from the molten rock. Denmark-based Rockwool International owns Roxul and supplies this type of product worldwide. The new plant planned for Mississippi is the first one in America.

Stone wool insulation is about three times more expensive than regular fiberglass insulation, but new home and remodel project owners should consider its long-term value plus its specific enhanced performance. The advantages of stone wool insulation are many. The unique non-directional structure of stone wool helps the absorption of acoustic waves, which reduces the intensity and propagation of noise. If installed correctly, sounds from adjacent rooms cannot be heard.

Because stone wool product is made basically from rock, it does not absorb water, making it more resilient in minor flooding events caused by busted water pipes or leaking roofs. If stone wool insulation does get wet, the homeowner should remove all wallboard or coverings and simply allow the product to air dry. Unlike other insulation that actually deteriorates or shrinks with age, stone wool maintains its basic physical characteristics for a lifetime.

The biggest advantage of stone wool insulation is probably its fire-resistant quality. Roxul maintains that its stone wool insulation can withstand temperatures up to 2150°F, which makes it an outstanding insulation product for walls near appliances and for creating a firewall between the garage and house. Firewalls in garage areas are becoming major concerns for fire protection as automobiles and water heaters pose some of the biggest fire threats in the home.

There is a growing demand for stone wool insulation because the benefits and features are well worth the extra price. Combined with a solid interior door, this product renders a bedroom or bathroom virtually soundproof. While you can insulate your entire home in stone wool insulation, most new project owners choose select rooms where privacy is essential.

Stone wool insulation is a superior product. It is fire resistant, water repellent, non-corrosive and resistant to mold. It should now become more affordable and accessible when the Roxul manufacturing facility in Mississippi opens because it will no longer have to be shipped from Canada.
