A roster (breeze block or ventilation block) is a hollow building element that is increasingly popular in modern homes in Indonesia. Not only functioning as natural air ventilation, rosters also serve as a decorative element capable of adding visual character to both the facade and the interior of a house. Its unique, hollow shape creates highly aesthetic plays of light and shadow, especially when sunlight penetrates its gaps during the day.
However, integrating a roster into a house wall design requires special attention, one of which is choosing the paint color for the surrounding walls. A color that does not harmonize with the roster's color can ruin the overall appearance, even if the roster design itself is already attractive.
Then, how do you choose the right paint color for walls with roster elements? Check out the complete guide below!
What is a Roster and Its Function on House Walls
A roster is a hollow block or panel building element usually made of brick, concrete, clay, or GRC (Glassfibre Reinforced Concrete). The holes in the roster function as a natural air circulation path so that the room behind the roster wall still gets good airflow without needing to fully open a window. This function is very relevant to Indonesia's hot and humid tropical climate.
Besides functioning as ventilation, rosters also play a strong aesthetic role. The play of hole patterns on the roster creates a facade that has character and is not monotonous. In the interior, rosters are often used as room partitions that provide visual boundaries without completely blocking light or air circulation.
Roster Design Inspiration for Modern Minimalist House Facades and Interiors
Rosters come in various sizes, patterns, and materials that can be adapted to your residential concept.
1. Red Brick Roster for Contemporary Tropical Facades
Red brick rosters provide a warm and authentic natural texture. It is very suitable for contemporary tropical or industrial style house facades that want to display raw materials honestly. Red brick rosters are usually left unpainted (exposed) or painted in earthy colors, such as terracotta, to strengthen the tropical feel.
2. GRC Roster for Modern Minimalist Facades
Glassfibre Reinforced Concrete (GRC) allows rosters to come in various clean and modern precision geometric patterns. GRC rosters are very suitable for modern minimalist house facades because of their neat appearance and they can be easily painted in any color according to the facade concept. Hexagon, diamond, and parallel line patterns are the most popular right now.
3. Roster as Interior Partition
Inside the house, rosters can function as partitions between the living room and dining room, or as a background for stairs. For the interior, rosters should ideally be painted the same color as the surrounding walls for a clean and unified look, or given a contrasting color to serve as a strong focal point.
Tips for Choosing Wall Paint Colors Around the Roster Area
Choosing the paint color around the roster requires more careful consideration compared to ordinary walls, because there are two elements that must harmonize: the wall color and the roster color/material itself.
Matching the Roster Color for a Clean Look
If you want a clean and minimalist look, paint the walls with the same or a very similar color to the roster. This technique makes the roster appear to blend in with the wall, so the hole pattern becomes a subtle yet noticeable architectural detail. This is suitable for minimalist homes that do not want too much visual contrast.
Contrast for a Strong Focal Point
Conversely, if you want the roster to be a striking focal point, use a contrasting color between the wall and the roster. For example, clean white walls with a matte black painted roster, or dark walls with a white roster. This contrast technique is very effective for emphasizing the architectural character of the house.
Consider the Wall Surface Texture
The meeting point between a roster and an ordinary wall often results in imperfect joints or surfaces with uneven textures. Avoid making mistakes in choosing colors so the results are maximized. This is where paint quality becomes very important. Paint with high hiding power will disguise this unevenness and produce a neater, more professional look.
How to Maintain Walls with Roster Elements to Keep Them Clean and Durable
Because they have holes, rosters are more susceptible to the accumulation of dust, dirt, and moss growth compared to ordinary walls. Clean the roster periodically using a small brush or a soft-bristled brush to remove dirt from inside the holes. For moss that has already grown, use a mixture of water and a special cleaning fluid before repainting.
When repainting, make sure the roster surface is completely dry and clean from dirt, moss, and peeling old paint. Use a small brush to reach the areas inside the roster holes so that the paint layer is even and no areas are missed.
