Protect your property and enjoy quieter, safer spaces with expert fire-resistant and soundproofing insulation from a team trusted since 1948.
Insulation does more than manage temperature. When it is selected and installed correctly, it also serves as a critical layer of fire protection and sound control for your home or commercial building. At Bonham Insulating, we help property owners throughout Upstate South Carolina choose and install the right fireproofing insulation and acoustic insulation materials to create spaces that are safer, quieter, and more comfortable.
With more than 75 years of experience serving homeowners, builders, and general contractors in the Upstate, we understand that every property presents unique challenges. A multifamily building may need fire-rated wall assemblies to meet code requirements. A homeowner finishing a bonus room above the garage may want to reduce sound transfer between floors. A commercial property may need both — fire resistance in structural assemblies and sound insulation between tenant spaces. Bonham's consultative approach means we evaluate your property first, then recommend the materials and methods that make sense for your situation.
Fire-resistant insulation slows the spread of heat and flame through walls, ceilings, and floor assemblies. In a fire event, the right insulation can delay fire spread for 30 minutes to several hours depending on the rated assembly, giving occupants more time to exit safely and emergency responders more time to act. Beyond life safety, fireproofing insulation helps protect structural components, reduces smoke production, and can lower property damage when the worst happens.
Common applications for fireproofing insulation include:
Unwanted noise from traffic, neighbors, mechanical systems, or even other rooms in your own home can affect comfort, sleep quality, and the overall livability of a space. Soundproofing insulation absorbs and dampens sound waves as they pass through walls, floors, and ceilings. The result is a noticeably quieter environment where you can work, rest, and live without distraction.
Sound insulation is especially valuable in:
