Would seem a pretty simple question right? And yes, it’s a pretty simple answer – cladding made from stone. However from the meetings I have with contractors and surveyors, I see it often gets over-complicated in designers’ minds and confused with traditional stone masonry.
Natural stone is one of the oldest materials used by man in construction. We only have to look at buildings such as the Taj Mahal completed in 1648 using white marble, or the Great Pyramid thought to have been completed in 2560BC made predominantly out of limestone to appreciate the longevity of stone as a material. (Imagine the architect specifying the Design Life for the Pyramid….)
Os métodos de construção mudaram obviamente desde que construíram o Taj Mahal, e graças aos diferentes sectores e profissões dentro da indústria da construção, referências cruzadas e redes ao longo dos anos, já não precisamos de empilhar pesados blocos de pedra uns sobre os outros para criar a aparência de um edifício de pedra sólida.
Traditional stone masonry (not something we do here at AlterEgo by the way), is loaded onto the building’s foundations and uses stones and mortar, tied back with wall-ties – think brickwork.
O revestimento de pedra moderno, por outro lado, é pendurado na estrutura do edifício e é montado da mesma forma que um sistema de proteção contra chuva de metal.
Você vê, revestimento de pedra, é um revestimento de tela de chuva sistema e deve ser tratado como tal.
Looking through a cross section of a typical stone cladding build-up you’ll see lots of familiar components: spreader bars, helping-hand brackets, rails and T-bars. It’s only the facing material which is interchangeable.
There are a few nuances when working with natural stone for the first time, but nothing that a day’s training and our on-site support won’t cover.
So if you’re a contractor used to installing aluminium and steel cladding or you specialize in terracotta; don’t be afraid of stone! Check out this video showing the simplicity of our EGO-02S system EGO 02s INSTALLATION BETA – YouTube
Quando se trata de fixar o painel de revestimento de pedra à estrutura de suporte, existem dois métodos principais de fixação:
With an undercut anchor system, typically used for larger format panels, holes are pre-drilled into the back of the stone, a sleeve and bolt inserted and fixed onto a hanging clasp and horizontal system. This method is good for natural stone panels with a thickness range from 30-50mm and can be used in both stack and stretcher bond layouts, typically in a portrait layout. Undercut anchors are always used in soffit situations.
Como as fixações estão todas na parte traseira do painel, este método é totalmente secreto, nenhuma fixação é visível.
The kerf method of fixing stone is where a continuous groove is cut in the top and bottom of the stone, and the stone simply sits on a rail or clasp at the bottom and restrained at the top. A kerf system works particularly well for horizontally laid panels in either stack or stretcher bond.
A rapidez e simplicidade de instalação, aliadas ao facto de os painéis poderem ser instalados de forma não sequencial, fazem deste método o sistema de revestimento de pedra mais utilizado.
Ambos os métodos de instalação são normalmente com juntas abertas, no entanto, as juntas pontiagudas com um selante não migratório podem dar a aparência de um edifício de alvenaria tradicional.
