Sandstones are classic sedimentary rocks with tiny sand sized quartz grained bonded within them over many years. These rocks are available in quite a few colours, namely, red, grey, pink, tan, brown, yellow, white and black. Other colours are also found in these rocks. A sort of a wall of sand stone veneer is used to decorate a building, office or residential house In order to adhere the stones to the wall a substrate is used.
Synthetic stone cladding products are fitted to lightweight substrates.
A typical substrate for synthetic stone cladding consists of
- Fibre cement sheet
- Waterproof barrier
- Timber stud frame
- Mortar scratch coat
- Expanded metal mesh
- In places where a very lightweight substrate is required, plywood is used instead of a fibre cement sheet.
In the case of real sandstone being adhered to a substrate mechanical fixing is often required with a shelf angle or stone clips to the substrate. This is because the natural sandstone is much heavier than synthetic stand stone.
The purpose Sandstone cladding is of having a sort of wall decorated with stone veneer is for the following reasons.
- Giving an existing structure a stone finish
- A lower weight with stone veneer thus having less structural frame requirements.
- A lower cost of construction as well as a speedier construction.
- To allow modern and effective lightweight steel construction frame, but with a traditional look of older times.
- Such allows offsite pre-fab manufacturing in order to have low on-site cost and time construction.
- Avoiding material, time and effort wastage.
Sandstone cladding is done by milling that into thin pieces often one inch thick. There are hundreds of variations in market demand styling so many different types of cuts and sizes are carried out. Cladding can be supplied as individual stones or complete pre-fabricated panels.
As mentioned earlier, sandstones being heavy are mechanically fixed onto the substrate layers with shelf angles or stone clips. Alternately a panel of lightweight concrete can have these sandstones adhered to them, as the almost similar materials tend to bond together nicely. These two materials form a composite tending to give good weather insulation, wall seepage protection from rain as well as harsh weather protection.
A house with stone cladding has an enhanced value and gives a very good aesthetic appeal. For comparatively little investment a large financial gain in real estate value can be attained.
