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!

Mold Resistant Building Material Solutions for Homes During the Rainy Season

gn-justify">Unpredictable weather keeps homeowners on higher alert. This is especially true during the rainy season, which often brings recurring problems for property owners, including mold growth and other damp areas on ceilings and walls. Mold growth and dampness damage a home's appearance and create an unpleasant odor that affects indoor air quality.

One way to prevent or fix this is by using quality building materials that are mold-resistant and moisture-resistant. This article will discuss the causes of mold growth on buildings, the areas of a home most prone to it, and recommended mold-resistant building materials worth considering.

What Causes Mold to Grow on Home Buildings?

Mold growth in certain areas is generally caused by a combination of high humidity, poor air circulation, and materials with high water absorption. When a wall or ceiling section is exposed to water and doesn't dry quickly, this creates an opportunity for mold to grow, particularly on natural and organic materials.

Areas of the Home Prone to Mold Growth

1. Ceiling

If there's a roof leak or poor air circulation, the ceiling is usually the first place where mold spots are found.

2. Bathroom or Kitchen Walls

Frequent activities in the bathroom and kitchen, such as bathing and cooking, mean these areas have high humidity levels, making them more prone to mold.

3. Outdoor Walls Rarely Exposed to Sunlight

Some outdoor wall sections receive minimal direct sunlight. This causes the walls to stay damp for extended periods and become an easy target for mold and moss growth.

4. Under-Stair Areas and Enclosed Spaces

These areas tend to have minimal air circulation. Air becomes more trapped, making them prone to mold development due to the persistent dampness.

Beyond damaging a home's appearance and affecting air quality, the long-term effects of mold growth include ongoing discomfort and accelerated material deterioration. If you've noticed these signs, it's advisable to address them promptly. Consider researching the issue and consulting an expert team who can help you choose a genuinely mold-resistant material.

The characteristics of a mold-resistant building material include a non-organic composition, a dense, non-porous surface, and low water absorption.

Recommended Mold-Resistant Building Materials

Ceramic tile can be used for wet wall areas such as bathrooms. Homogeneous tile can also serve as an additional coating layer to help reduce the risk of mold, though the base material's water resistance still needs attention. These can be combined with GRC board, a cement-based material. This material offers the advantage of being both mold- and moisture-resistant, and is well-suited for use on ceilings, outdoor walls, and wet walls such as those in bathrooms and kitchens. Its dense surface makes it harder for mold to grow compared to organic-based materials.

Tips for Preventing Mold Growth Besides Replacing Materials

Steps you can take include ensuring good air circulation, using anti-mold paint or coating as extra protection, cleaning damp areas regularly to minimize mold growth, and fixing any leak sources if present.

GRC board is here to help provide a solution for creating a healthier home, even when facing the rainy season year after year. Consult your home's building material needs with an expert today!

Extreme Weather Resistant Building Materials You Should Consider

gn-justify">Extreme weather is an issue that recurs every year in Indonesia. The Meteorology, Climatology, and Geophysics Agency (BMKG) regularly issues advisories regarding the potential for heavy rain and strong winds across various regions. This can lead to high humidity levels, which in turn triggers rain cloud formation in parts of Indonesia.

Extreme weather brings fear and discomfort, particularly for homeowners. Its effects can impact the very structure and materials that form a home's foundation. This article will discuss the impact of extreme weather on buildings, along with recommendations for building materials that can withstand it.

What Does Extreme Weather Mean?

Extreme weather can take the form of very heavy rain within a short period, strong winds, high-temperature sun exposure, and intense lightning. In Indonesia, it most often appears as heavy rain accompanied by strong winds, which can ultimately lead to natural disasters.

The Impact of Extreme Weather on Home Buildings

1. Roofs and Gutters Are Easily Damaged

Heavy rain with high water intensity can accelerate damage to exterior components such as roof tiles, gutters, and roof underlays that were not designed to withstand high rainfall on a repeated basis.

2. Walls and Ceilings Are Prone to Dampness

The rainy season causes walls and ceilings to absorb water more easily. This can ultimately lead to dampness and even mold growth.

3. Materials Easily Expand and Contract

Repeated temperature changes from hot to cold can cause some building materials to expand and contract, leading to fine cracks on the surface.

4. Risk of Corrosion on Metal Materials

A prolonged rainy season increases the risk of corrosion, particularly on materials with a metal base, such as lightweight steel frames.

Criteria for Extreme Weather-Resistant Building Materials

There are several criteria to look for so a building is better prepared and sturdy enough to face extreme weather, such as resistance to temperature changes, mold resistance, and low water absorption. One building material known for withstanding extreme weather is GRC board. This cement-based panel material is designed to handle extreme weather conditions. GRC board holds up better against moisture even as temperatures shift. It also withstands extreme heat exposure without easily expanding, making it suitable for a variety of home elements such as exterior walls, ceilings, roofs, and facades.

Tips for Protecting Your Home from Extreme Weather

  1. Regularly check the condition of your roof and gutters, especially ahead of a seasonal shift.
  2. Apply waterproofing to vulnerable areas, such as concrete decks and roof joints.
  3. Replace materials showing signs of damage before extreme weather reaches its peak.
  4. Choose materials with clear, proven resistance to extreme weather conditions.

All preventive measures will be most effective when supported by the selection of building materials specifically designed to withstand extreme weather, such as GRC boards. Consult with an expert today about your needs for materials that can withstand extreme weather, whether for commercial buildings or homes!
