Some products help us use other products or materials more efficiently. For example, drywall clips allow the elimination of corner studs, engineered stair stringers reduce lumber waste, and concrete pigments and polishing systems can turn concrete slabs into attractive finished floors. We also recognize some products, like vacuum plumbing systems, which use less material than their conventional counterparts. Many products with this attribute are fairly unique, so we bring a skeptical eye to manufacturer claims, but not a specific standard.
No-Coat is an all-in-one drywall corner system that incorporates a PET core, joint tape, and surface. Unlike typical corner beads, which are often tacked in place, require significant amounts of joint compound, and are prone to cracking, No-Coat’s structural laminate design, or SLAM (which doubles for “saves labor and mud,” says the company) contains a joint tape that bonds to joint compound, an impact-resistant core, and surface paper. Use of No-Coat reduces the amount of joint compound needed for corners by 50%, according to the manufacturer. These products are available in Ultraflex for off-angles, Ultratrim for vertical corners, and Ultraaarch for archways.
Joint compounds can create indoor air quality problems by promoting mold growth or introducing VOCs and other pollutants into the building. Powdered, dry-shipped, site-mixed joint compounds are less prone to mold growth than pre-mixed buckets and require less packaging and shipping energy.
GreenSpec lists products that use low-VOC compounds or that have other environmental features or benefits.
