GRC is produced mainly through (1) the Direct Spray method (DS), or the (2) the Premix method(PM). DS involves spraying both mortar and glass fibres onto the mould simultaneously. PM involves combining and mixing mortar and glass fibres and pouring the mixture into the mould. There are multiple techniques involved beginning with the metal mould, and the most suited technique to the GRC panel shape and specification is chosen.

GRc is not only freely shapeable with curves, openings, slits, and surface textures, there are also many ways in which to finish the surface. For example, it can be painted with enamel, metallic paint, stucco, stone-like spray paint, colour-clear paint, or inlaid with surface materials, such as stone, tiles, aluminum, teracotta, framed with stone, transparent materials, glass, or treated with sand blasting, cosmetic washing, water-sand blasting, and polishing.

Typical heat-formed strengthened glass is made by heating float glass and then rapidly cooling it, such that a layer of compressed tensile stress is formed on the glass surface. On the other hand, chemically strengthened glass is glass dipped in potassium nitrate solution, the resulting ion exchange creates the layer of compressed tensile stress, increasing the strength of the glass.

BIM, short for Building Information Modelling, has as its goal, the conferment upon 3D models various information, to enable the centralised management and pro-active use of information. Through actual commercial projects and cooperation with partner firms, we have been actively researching how to optimise the use of BIM in facade engineering.

3D modelling allows us to reduce wastage in later stages, as it becomes easy to check each part of the façade for interference, in addition to helping us form a consensus as regards the image of the final product early.

One way of creating shapes through 3DCAD. It facilitates technical verification and early proposals for design changes.

The Finite Element Method was developed to analyse parts with complex shapes and structures. FEM

Wind noise is prevented by conducting computer simulations and wind tunnel experiments, and reflecting these results in the form and structure of the louvres. In addition to calculations, on occasion, to verify the form of the louvres, actual experiments are conducted with wood models, and test subjects are created from actual materials.

Dot Point Glazing or DPG is a configuration whereby holes are drilled into th four corners of strengthened glass and double-strength glass panels, and a rotatable special bolt is installed to hold it in place. As there is no sash frame around the glass, a glass façade that is both flat and transparent is achievable.

With Metal Point Glazing or MPG, the glass edges are held in place by specialised parts from from inside and outside. As there is no sash frame around the glass, a glass façade that is both flat and transparent is achievable.

Piece Frame Glazing or PFG is a configuration, whereby the glass edges are held in place by specialised parts from from inside and outside. As there is no sash frame around the glass, a glass façade that is both flat and transparent is achievable.

Structural Silicone Glazing or SSG is a configuration whereby the glass is glued to the exterior sash with structural silicone sealant. As there is no thermal bridge, a reduction in the need for indoor air-conditioning and dew condensation prevention can be expected.

Glass strip holders are installed before the metal mullions, ans held in place by silicone to the glass panels. The external-facing side is fully flat, and dead space in in the interior is minimised.

Actual testing using actual samples is conducted to verify the results of structural calculations on paper at the planning stage.

As exteriors have to be safe under conditions of earthquake and wind pressure, the durability of the exterior has to be examined through repeated load bearing tests.

This includes everything from original façade panels, parts, specially sized parts, extra large parts. We propose and execute plans according to the characteristic of the product from the transportation aspect, to the installation, the erection, and the hauling.

The question is how to install a specially sized object at the right spot. For efficient installation on site, the line of movement of the object has to be calculated in reverse from the goal, appropriate scaffolding measures have to be made, and coordination and communication with the main contractor is of utmost importance. This is an especially important point for AGB, as we deal often with specially sized objects.
