  2. Function of a wall A wall performs a number of functions… • A walls main function is to transfer the loads of a building safely to the ground • A walls also: • Reduces sound transmission • Provides shelter and security • Resists heat transfer – (prevents heat loss from a building)

  3. Detailing a wall This is the process of producing a drawing that contains all the details about the construction of a wall. • External walls • - Mainly constructed as cavity walls using bricks and blocks. • Internal walls • Tend to be constructed using timber. • Can be constructed in solid blockwork if they are to be load bearing. • Can also be constructed as metal stud walls, made of aluminium, with glass panels

  6. Wall finishes Rendering brickwork – this is a process similar to plastering. Render is applied to bare brick and block work and can be given different textures. Facing brickwork – is the brick work that you see when looking at a building Mortar joints are usually pointed to improve weather proofing and the appearance of the brickwork. There are four different types of finish that can be applied: Bucket handle Weathered Flush Recessed Bucket handle and weather struck give better weather resistance.
