Exploring R‑Class Member Benefits, Rebates and More

DEC 12, 2022

From virtual building science webinars to in-person connections with residential building experts, the ROCKWOOL R‑Class Builder Program is our premium partnership for builders who want more. By joining the R‑Class, you also receive access to ROCKWOOL builder support on products, technical questions and even scheduled jobsite visits.

And we reward our R‑Class members for their commitment to using ROCKWOOL. Through the R‑Class rebate program, purchasing ROCKWOOL insulation for your residential building projects can put money back in your pocket — along with a wide range of additional benefits based on the quantity of ROCKWOOL insulation purchased.

There are two things that separate R‑Class builders from other builders in our market: fine craftsmanship and building science. – Matt Risinger, Risinger Build and The Build Show

Insulation That Performs

ROCKWOOL stone wool has unique benefits as an insulation solution, providing not only strong thermal value but also natural fire resistance, water repellency, dimensional stability, durability and long-term sustainability.

Our three residential products — Comfortboard 80 rigid board insulation, Comfortbatt thermal batt insulation and Safe'n'Sound acoustic batt insulation — are essential parts of any high-performance home.

ROCKWOOL Comfortboard® 80 provides a continuous layer of insulation, reducing thermal bridging and increasing the effective thermal performance of the building envelope with an R-value of 4.2 per inch. Typical applications include:

  • Exterior wall thermal insulation
  • Basement continuous insulation
  • Exterior perimeter insulation around the foundation
  • Under flat concrete slabs
  • Cathedral ceilings

ROCKWOOL Comforbatt® features a unique flexible edge that allows for easy installation and helps prevent overcompression to maintain its R-value. Simply insert, compress and release the batt in between the studs for a snug and complete fit. Typical applications include:

  • Exterior wood- and steel-framed walls
  • Exposed floors and crawl spaces
  • Attics and cathedral ceilings
  • Basement walls between studs

ROCKWOOL Safe'n'Sound® provides an innovative, high-density insulation that’s specifically designed to absorb sound and help prevent noise from traveling between rooms. Unlike thermal insulation, it’s used for soundproofing interior walls and ceilings between rooms and floors. Typical applications include:

  • Bedrooms
  • Bathrooms
  • Home offices
  • Home theater rooms
  • Basements
  • Furnace/laundry rooms

So, why is ROCKWOOL stone wool insulation the right solution for your next project? We asked residential building expert Matt Risinger for the answer to that question, and he gave us seven reasons he used ROCKWOOL to insulate his own house.

“Fire resistance is a big reason I like ROCKWOOL,” Matt says. “But one of the things I also like about it is that it’s relatively straightforward to install. When you are working with it, you don’t need a lot of PPE — typically you’re going to wear long sleeves, gloves and a dust mask. And it’s easy to install with just one main piece of equipment — a long, serrated knife for cutting pieces to friction fit.

”That’s in comparison to a lot of other insulation products: When you think about the guys using spray foam in a house — you have a giant rig, you have hoses, you have respirators and you have off-gassing to deal with.”

In addition to ease of use, Matt highlights other benefits to installing ROCKWOOL, including the usefulness of product labeling, the vapor-open nature of the product and its water repellency.

He’s also a big fan of how much sound control Safe'n'Sound insulation provides for a house.

“This product absolutely absorbs sounds. In fact, I actually built my studio with this … so that it would give us that noise abatement,” he adds.
