A Wood Look Facade Without Termite Worries at Umma Arsa Housing

A Wood Look Facade Without Termite Worries at Umma Arsa Housing

The facade is the first part of a home that catches the eye. Many developers and homeowners now pay more attention to facade decoration materials, not just paint color. Wood-toned brown still remains a favorite, but for long-term durability, real wood needs regular and periodic maintenance.

One solution can be seen at the Umma Arsa housing complex in Depok. The area offers attractive home designs, some of which use GRC Rafter Stick board as facade decoration. This article discusses why GRC board is worth considering, along with its size specifications.

GRC Rafter Stick Material from GRC Board

GRC Rafter Stick is a GRC board product shaped like long sticks. This material is designed to be installed in repetition like a lattice, a room divider, or as decoration for facades, exterior walls, and other exterior elements. The GRC material itself is made from a cement mixture, making it more resistant to rain, moisture, termites, and mold compared to other natural materials.

Specifically at this housing complex, GRC Rafter Stick is used in two different designs. In one, the sticks are installed in repetition at uniform spacing, so from a distance they look like a single, continuous striped wood panel, right on the outermost part of the house. In the other, it serves as wall decoration, specifically at the vehicle parking area, or carport.

This material is often referred to as GRC wood-motif board, because the surface detail on both sides resembles mahogany wood grain. GRC Rafter Stick board comes in two sizes: 20 mm thick x 100 mm wide x 2400 mm long, and 20 mm thick x 100 mm wide x 3000 mm long. For price calculations

Why Is GRC Board Suitable for Exterior Walls and Facades?

This part of the house is exposed to rain and heat every day. Materials used here need to withstand those conditions. The advantages of GRC board products include:

  • Weather-resistant, with better resistance to rain and moisture
  • Termite-resistant, since its cement base is not a food source for termites
  • Mold-resistant, since its denser surface makes it harder for mold to grow
  • Sturdier, minimizing the need for routine maintenance

The facade decoration at Umma Arsa housing shows that a natural-looking finish can be achieved without the risk of termites and rot. With GRC Rafter Stick, facade decoration can be made neater, weather-resistant, and easy to maintain. Consult your project's GRC board needs with our expert team today!

An Industrial Themed Home with GRC Concrete Panel

Interior design has become one of the main draws of a home these days. GRC board walls are one approach that's increasingly being chosen for this. GRC board material is now more varied and flexible, able to be adapted to any design concept, from modern minimalist to contemporary industrial styles. One real example of this GRC wall application can be seen in the home of content creator couple Vina and Jawir. They entrusted their home's interior walls to GRC board material.

The GRC material used is the GRC Concrete Panel type, one of the standout GRC materials known for delivering a modern look without going through a complicated casting process. This article will cover how the GRC material was applied, the size of the GRC Concrete Panel used, and why this material suits a variety of home interior concepts.

GRC board Walls with an Industrial Touch

This comedic content creator couple wanted to refresh the atmosphere of their home. Previously, their wall condition had developed stains, especially since the original paint color was white. This could have been solved with a fresh coat of paint, but they decided to add a decorative touch that was both easy and quick to apply. One option was installing GRC material in the GRC Concrete Panel type.

The GRC Concrete Panel size used on this home's walls is 10 mm thick x 600 mm wide x 600 mm long. For a few spots, such as near the light switch and the stair corner, they cut the panels so the result still looked neat and solid. This GRC material was then painted in a brownish taupe color. The combination pairs perfectly with the brown wood-toned stair steps and black iron railing.

The main advantages of this GRC material are that it's easy to install yourself, has a faster installation process, and is resistant to termites, mold, and dampness. This means it can last longer and stay sturdy for decorating a home over time.

Explanation of Modular and Instant Home

Explanation of Modular and Instant Home

When looking for alternative ways to build a home that are faster and more efficient, two terms often come up. These two terms are modular home and instant home. These two terms are often thought to mean the same thing, but there's a slight difference between them, even though they stem from a similar basic concept.

This article will explore the differences and similarities between modular homes and instant homes, so sobat GRC enthusiasts can better understand which term best fits the type of home they want to build.

What Is a Modular Home?

A modular house is a house built from components or modules that are produced separately, then assembled into a single, complete building on-site. This concept emphasizes a construction system made up of individual parts, which can be arranged or combined according to design needs and building size.

The term "modular" leans more toward the system used to arrange building components. This means it can be applied to various types of materials, ranging from sandwich panels and precast concrete to GRC board.

What Is an Instant Home?

An instant home is a house that can be built in a short amount of time because it uses ready-to-install materials. In Indonesia specifically, the term instant home can be seen in the RISHA (Rumah Instan Sederhana Sehat, or Simple Healthy Instant Home) product from the Ministry of Public Works and Public Housing (PUPR). RISHA is built from reinforced concrete components connected with special bolts, using red brick as a connecting element.

The term "instant home" itself emphasizes the speed aspect, without referring specifically to any particular construction system.

Similarities Between Modular Homes and Instant Homes

Despite their different areas of emphasis, there are several basic similarities between the two, such as:

  • A shorter construction time
  • Design flexibility, since the components used can be adjusted to suit various size and layout needs

Long-Lasting, Sturdy Modular Homes with GRC board Material

One of the largest cement board manufacturers in Indonesia, GRC board, also offers modular homes built for long-term durability. These come in two types: the GRC Dry Wall Modular Home and the GRC Panel Modular Home.

The GRC Dry Wall Modular Home is a prefabricated home whose walls use GRC cement board on both the exterior and interior, fitted with a lightweight steel frame, resulting in a sturdy structure with guaranteed quality. Its lighter material also makes it easier to distribute to remote areas and keeps costs lower.

The GRC Panel Modular Home is a prefabricated home that uses GRC panel walls made from a mixture of cement and styrofoam beads with a GRC board outer skin, making it denser and stronger, as well as efficient to install. It also helps keep interior spaces cooler and more soundproof.

In short, the GRC Dry Wall Modular Home stands out for its lightweight material, affordability, and ease of distribution, making it well-suited for large-scale projects or hard-to-reach locations. Meanwhile, the GRC Panel Modular Home stands out for its denser structure and interior comfort, offering a cooler, more soundproof living space.

Both options offer a faster and more flexible way to build a home compared to conventional methods. GRC board's modular homes are here to meet that need through two choices: the Dry Wall and GRC Panel options. Our team of experts is ready to provide information and consultation for your home needs.

One GRC board Material for All Your Modular Home Needs

One GRC board Material for All Your Modular Home Needs

The demand for housing that's quick to build yet still affordable is drawing increasing interest, whether for a private residence, worker housing at a project site, or large-scale housing programs. The instant home concept involves building a house using ready-to-use materials, allowing the construction process to be much faster and shorter compared to conventional methods using brick and plaster.

Among the various types of instant homes developed in Indonesia, the GRC board modular home also stands out as an appealing option. Beyond speed of construction, instant or modular GRC board homes also offer structural strength.

What Is a GRC Board Modular Home?

A GRC board modular home is a housing concept built using GRC cement board as the material, applied to the main elements, including walls, ceilings, partitions, roof underlays, fascia boards, and interior and exterior decorative elements, all in the form of GRC board panels. This allows the construction process to be completed much faster, in as little as 7 days. This differs from the typical home-building timeline, which can take months depending on the type and size of the building chosen. What's more, GRC board wall panels can add an aesthetic touch through their detailed textures and motifs.

Why Choose a GRC board Modular Home?

1. Resistant to Termites, Mold, and Extreme Weather

GRC board, as the main material, offers greater resistance to moisture, mold, and termites, and can withstand extreme weather changes throughout the year. In other words, GRC board can be a solution for extreme weather-resistant building material.

2. Faster Construction Process

Installation is faster because GRC board panels are already available in sheet form. GRC board sheet sizes range from 1200 mm width x 2400 mm length up to a maximum of 1220 mm width x 2440 mm length, ready to be installed directly onto a pre-assembled frame.

3. One Material for a Variety of Needs

An advantage of the GRC board modular home is the use of a single material type across various parts of the house, from interior and exterior wall applications to interior and exterior decoration. This simplifies material procurement and results in a more consistent outcome in terms of quality and appearance.

An Overview of GRC Board Modular Home Specifications

Generally, an instant GRC board home uses a lightweight steel frame as its main structure, which is then covered with GRC board panels on both the interior and exterior walls, with thickness adjusted as needed. Finishing elements such as fascia boards and facade decoration also use decorative GRC board types, such as GRC T-Line in a Rosewood motif or GRC Deco Panel, keeping the home's appearance aesthetic even though it's built quickly.

A GRC board modular home can be one of the best housing solutions built within a short timeframe, offering a home that's far sturdier, resistant to extreme weather, and low-maintenance in the long run. Consult your GRC board modular home needs directly with an expert today!
