Consider a composite wall that includes an 8-mm-thick hardwood siding, 40-mm by 90-mm hardwood studs on 0.65-m centers with glass fiber insulation (paper faced, 28 kg/m³), and a 12-mm layer of gypsum (vermiculite) wall board. What is the thermal resistance associated with a wall that is 2.5 m high by 6.5 m wide (having 10 studs, each 2.5 m high)? Assume surfaces normal to the x-direction are isothermal.

Masonry wall construction

Masonry walls of various sorts are utilized in building construction. Masonry walls are the most enduring feature of any structure or building. It separates a structure from the outside world. In masonry construction, the common masonry materials used are building stone, brick, cast stone, glass block, and concrete block. Masonry construction is a type of construction that has the highest durability.
