The purposes of the walls and in buildings are to support roofs, floors and ceilings to create a space that is part of the building envelope.
Wall construction falls into two basic categories:
- Framed walls – In framed walls, the load is transferred to the foundation through posts, columns or studs. Framed walls most often have three or more separate components: the structural elements (such as 2×4 studs in a house wall), insulation, and finish elements or surfaces (such as drywall and panelling).
- Mass-walls are of solid material including masonry, concrete, including slip form, stone masonry, log building, cordwood construction, abode, rammed earth, cob, earthbag construction, bottles, tin cans, straw-bale construction and ice.
There are three basic methods walls control water intrusion: moisture storage, drained cladding, or face-sealed cladding.
- Moisture storage is typical of stone and brick mass-wall buildings where moisture is absorbed and released by the walls of the structure itself.
- Drained cladding also known as screened walls acknowledges moisture will penetrate the cladding so a moisture barrier such as housewrap or felt paper inside the cladding provides a second line of defence and sometimes a drainage plane or air gap allows a path for the moisture to drain down through and exit the wall. Building walls frequently become works of art, externally and internally, such as when featuring mosaics work or when murals are painted on them; or as design foci when they exhibit textures or painted finishes for effect.
- Face-sealed cladding wall systems often require and rely on effective seals between joints in order to maintain a viable barrier. At each joint, opening and transition, the wall may be more prone to leaking than elsewhere, and as the face composition becomes more complex, it becomes more difficult to seal. While designs for face sealed cladding wall systems can vary, most incorporate gaskets, liquid sealant and caulks to fill joints and gaps. Flashing and gutters are also necessary to channel water away from prone areas and to protect them from exposure. Porous surfaces, such as concrete, are often treated with a surface applied sealant to block absorption. A few of the ‘face sealed’ systems currently in use are curtain walls, metal-clad foam panels, and some EIFS systems.
Floor and Floor components
A floor and floor components typically provide:
- Structural support for the contents of the room, its occupants, and the weight of the floor itself.
- Resistance to the passage of moisture, heat and sound.
- A surface finish which may contribute to the look, feel and acoustics of a space.
In general, floor construction tends to be, solid floors, suspended floors, and varying options around these basic types.
The certification we provide within this space is to determine:
- The intended use of the floor or floor components
- The structure in relation to the rest of the buildings and
- The required floor finish which will determine which of the many variations is most suitable for a particular application.
