sopra si intende al plurale:
pareti di cartongesso (con un'intelaiatura di legno)/muri di assi in legno

eventualmente, se sei vincolato ad usare cartongesso da "sheetrock" presente nella frase successiva, forse potresti anche considerare direttamente "pareti/muri con intelaiatura in legno" o "pareti con assi in legno"

un altro link credo utile per quanto riguarda i "wood wall studs" che costituiscono l'intelaiatura delle assi verticali di legno inserite all'interno di pareti/muri:
A *wall stud* is a vertical member in light frame construction. Traditionally, studs were made of *wood*, usually 2×4 or 2×6 dimensional lumber. In North America, studs are typically placed 16 inches (400 mm) from each other's centre, but sometimes also at 12 inches (300 mm) or 24 inches (600 mm). Steel studs are gaining popularity, especially for non load-bearing walls.
When mounting an object such as a shelf, to a wall and maximum strength is desired, the goal is to attach the object to the *studs in the wall*, as mounting to drywall or plaster is only as secure as the material being mounted to.
