As a trusted distributor, GMS combines an extensive inventory of Rockwool insulation products with local know-how and reliable delivery services from coast to coast.

GMS offers Rockwool insulation solutions for wall insulation and roof insulation applications. These high-density stone wool products support modern wall systems, continuous insulation strategies and high-performance building envelopes.

Rockwool wall insulation products support both interior wall and exterior wall assemblies across residential and commercial projects. Options include batt insulation, semi-rigid insulation boards and cavity insulation designed to fit cleanly between each stud.

Stone wool insulation helps control heat loss, improve energy savings and enhance acoustic comfort inside wall cavity spaces. These insulation products resist moisture, integrate smoothly with vapor barrier and membrane systems, and perform well during retrofitting work. Rockwool Comfortbatt® remains a trusted solution for interior wall insulation and sound-sensitive wall assemblies. Roof Insulation Solutions

Rockwool roof insulation supports both flat roof insulation and pitched roof applications. Roof insulation boards deliver consistent thermal insulation, strong fire resistance and long-term stability under load.

Stone wool insulation performs reliably around rafters, beneath membranes and within complex roof assemblies. These insulation materials maintain performance during temperature swings and moisture exposure, making them a dependable choice for exterior roofs and demanding roof systems.

Insulation delays can disrupt framing, drywall and exterior schedules. To avoid these interruptions, GMS maintains access to a broad range of Rockwool insulation products, including batt insulation and insulation boards, across our nationwide network.

Projects often require specific R-values, thicknesses or product configurations. When a Rockwool insulation product is not stocked locally, GMS coordinates special orders to match job requirements and installation schedules.

GMS deliveries go beyond simple drop-offs: Our boom-and-scatter service places Rockwool insulation materials where crews work floors, roof levels or staging areas which reduces re-handling, improves workflows and supports safer job sites

With more than 300 locations across North America, GMS combines local insulation knowledge with the scale needed to support projects of any size. Our teams understand wall systems, roof assemblies and continuous insulation strategies, helping customers select the right Rockwool solutions for each build.

From insulation for exterior walls to roof insulation boards for flat or pitched roofs, GMS supplies Rockwool products built for durability, safety, and energy savings. Visit your local GMS yard to connect with an insulation expert or request a quote for your next project.
