Secondary Skin GRC board Bring Building Facades to Life

Today’s exterior material needs go beyond simply covering walls, they aim to create something more that enhances aesthetics while maintaining functionality. One of the current trends is the use of a secondary skin on buildings. Generally, this element is often found in façade applications or on the outermost parts of a building.

A recommended material for building secondary skin applications that offers a modern look and long lasting durability is GRC Rafter Stick. This application can enhance and bring the building’s facade to life.

What Is a Secondary Skin on a Building?

This term is not commonly heard among the general public but is well-known among professionals in certain fields. A secondary skin is an additional second layer, the outermost layer on a building’s facade that is not directly attached to the main wall. This layer can act as a visual filter. Especially in tropical countries like Indonesia, the use of a secondary skin is highly effective in reducing and filtering direct exposure to the sun’s heat. All without obstructing air circulation.

Additionally, this outer layer can enhance residents’ privacy while enhancing the aesthetics to give the facade a modern minimalist look.

Until now, natural materials have been the go-to choice for building facades. However, natural materials are quite vulnerable to weather changes, weathering, and termite infestations. As a solution, GRC board introduces the GRC Rafter Stick, a material in the form of precisely shaped rectangular profiles. This material is designed for both interior and exterior decorative elements. The GRC Rafter Stick is currently the best secondary skin material available, offering superior visual appeal combined with the durability of cement board.

Advantages of GRC Rafter Stick for Building Facades

In terms of maintenance, GRC Rafter Stick is a low-maintenance material compared to natural materials. It only requires periodic repainting to restore its like-new appearance.

The Advantages of GRC Board as a Roof Overhang Material in Tropical Climates

A roof overhang is an extension of the roof that protrudes beyond the wall. Its function is to protect exterior walls from rain splashes, minimize the amount of sunlight entering the room, and serve as an aesthetic element of the home. In this context, a material is needed that can withstand UV exposure, heavy rain, and daily temperature fluctuations.

One material suitable for roof overhang applications is GRC board. The base material of GRC board is cement that has undergone pressing and durability testing as a building construction material. Its denser structure provides GRC board with extra strength. When heavy rain flows over the GRC board roof overhang, the water will run off and dry without damaging the board’s structure. Additionally, the material is mold-resistant, termite-resistant, and weather-resistant. This contrasts with some other materials that may experience delamination when used in weather-exposed areas.

Aesthetically, GRC boards used as roof overhangs come in a variety of designs. These range from standard roof overhang types with a smooth surface to those with textured surfaces resembling wood grain details. An example is the 8 mm thick x 200 mm wide x 3000 mm long GRC Ecoline Mahogany.

GRC boards are a suitable and recommended choice for roof overhang applications, particularly in tropical climates. Their advantages including resistance to rain exposure, UV resistance, fire resistance, mold resistance, and ease of finishing make GRC boards a long-term investment for building owners. So, consider using GRC boards as the primary material for your next construction or renovation project.
