Wood Walls - Header, 2x, Insulated Drawings & Dimensions

A wood wall 2x insulated header is a built-up header constructed using 2x lumber to form a 'U' shape, leaving a space in the middle for insulation. Typically, two pieces of 2x lumber are used vertically on either side, with a third piece connecting them horizontally at the top, creating a 'U' shape.

木制墙体双面隔热横梁，系由两根2x木料构建而成的复合横梁，形成一‘U’形结构，其中部预留空间以便填充隔热材料。通常，两侧各垂直放置两根2x木料，顶部再横置一根木料将两侧连接，形成‘U’形。
