Manufacturers Reserve Supply (MRS), a leading two-step distributor of specialty building materials serving the Northeast and Mid-Atlantic, today announced a new distribution partnership with RISE siding and trim by CertainTeed. Through this partnership, MRS will bring the innovative composite siding product to retailers across the region with local inventory and rapid fulfillment.
RISE siding has already generated strong demand in the marketplace due to its durability, curb appeal, and versatile product offering. By stocking the product locally, Manufacturers Reserve Supply will enable dealers to place orders ranging from single pieces to full units and receive them within days—helping retailers respond quickly to contractor demand.
Manufacturers Reserve Supply is widely recognized for bringing premier building product brands to market through a strong distribution network and a commitment to service. The addition of RISE expands the company’s specialty exterior building materials portfolio and fills an important need for retailers seeking innovative siding solutions.
“RISE is an exciting addition to our exterior product lineup,” said Brian Boyd, president of Manufacturers Reserve Supply. “Our team is focused on bringing high-quality, in-demand brands to the dealers we serve. By stocking RISE locally, we can help our customers respond quickly to contractor needs while giving them access to a differentiated product that complements the CertainTeed family of offerings.”
Manufacturers Reserve Supply will maintain a full stocking program for RISE siding and trim, including 20 prefinished colors as well as primed boards. The inventory will include plank, sheet, batten, and trim profiles, allowing retailers to meet a wide range of architectural and design needs.
RISE siding and trim products are engineered to withstand the demands of the jobsite while delivering the beauty and curb appeal of a premium composite siding product. Manufactured using quality synthetic fibers—including polyester, nylon, and fiberglass—RISE provides a durable, affordable, and long-lasting siding solution for residential applications.
“At CertainTeed, we’re committed to delivering innovative building solutions that raise the bar for performance, resilience, and sustainability,” said Linsey Holden-Downes, director of product management at CertainTeed. “Our partnership with Manufacturers Reserve Supply strengthens that commitment by expanding access to RISE siding across the Northeast. MRS’s trusted distribution network and deep relationships with dealers and contractors make them an invaluable partner as we bring this durable, wood-like, and highly resilient siding solution to more professionals throughout the region.”
With the addition of RISE, retailers that already carry CertainTeed products will gain a complementary siding solution that supports today’s growing trend toward mixed-material exterior designs, while dealers new to the CertainTeed family will have an opportunity to expand their exterior product offerings.
