Armourstone

 
 


ARMOURSTONE is a toughened safety glass with an integral, simulated stone finish. It opens a whole new spectrum of possibilities for the cladding of buildings - both on the exteriors and interiors.

The standard ARMOURSTONE range includes nine granite finishes and two marble finishes - extending from the subtle coffee creams of Boticcino to the dark wood green of Ubatuba and through a selection of grey, brown, black and red granites. Each comes with its own subtle colour emphasis.

NB Virtually any polished stone finish can be replicated in ARMOURSTONE on minimum order quantities of 400m2. Where alternative stone matches are required, six to eight weeks must be allowed for processing and sample approval prior to production commencing.

ARMOURSTONE can also be supplied in selected patterns in the DecorVue range. Contact PFG Building Glass for details.

Manufacture

ARMOURSTONE is produced by transferring a photo image of the specified stone finish to the glass. During the toughening process, in which the glass is subjected to temperatures of up 625 °C, the silica inks which make up the stone image are fused permanently into the back surface of the glass, ensuring the integrity of the material and its enduring colour fastness.

Applications

Like the other toughened glass products manufactured by PFG Building Glass - Armourplate clear or tinted toughened safety glass, Armourscreen silk-screened toughened safety glass, and Armourclad coloured, enamelled toughened safety glass - ARMOURSTONE provides safety and structural strength in all its applications, together with the added aesthetic dimension of a polished stone finish.

Cladding
ARMOURSTONE is ideal for cladding commercial buildings - office buildings, hotels, leisure and entertainment resorts, retail complexes - to mention a few. It is equally applicable to exterior and interior surfaces. Further specific applications include entrance assemblies and the overcladding of spandrel panels, or any application where a highly durable and distinctive finish is required.

Characteristics

Light Weight
ARMOURSTONE toughened safety glass is produced in a standard 6 mm thick toughened safety glass. As such, it is considerably lighter in weight than many comparable cladding materials. This introduces cost savings for on-site handling and installation.

Installation
The 6 mm thickness of ARMOURSTONE also makes it compatible with vision panels where clear or heat reflecting laminated glass of a similar thickness is most often used. Thus the structural frame for cladding and fenestration can be uniform.

Impermeability
Glass is a non-porous material which makes ARMOURSTONE toughened safety glass impermeable to water and to staining or deterioration from pollutants carried in rain or airborne moisture.

Opaqueness
ARMOURSTONE is opaque, with the stone finish covering the full face of the glass.

Hygiene
The impermeability and inertness of glass makes it a hygienic material, an added benefit when combined with the opaqueness of an integral stone finish in ARMOURSTONE.

Durability
Because the stone image is fused into the glass, colour-fastness is ensured and, like all glass, ARMOURSTONE toughened safety glass is weather-proof, resistant to corrosion and easy to clean.

Structural strength
As a toughened safety glass, ARMOURSTONE is at least five times stronger than ordinary float glass. It is thus suitable for structural and safety glazing and can be used in flush glazed assemblies. ARMOURSTONE has a high resistance to impact and wind loading. It also withstands extreme heat and cold with a thermal differential-shock capacity of some 200 °C.

Safety
In the unlikely event of ARMOURSTONE being broken, the glass disintegrates into small, relatively harmless particles and so minimises the injuries often associated with broken glass.

Drilling and Edge Working
ARMOURSTONE cannot be cut or worked after it has been toughened because, with the balanced stresses set up in the glass during the toughening process, any working is likely to cause breakage. All sizing of the glass and any drilling or edge working must therefore be completed before the glass is toughened.

It is important to note that while colour variation will be minimised as far as possible, colours can vary marginally between production batches.
