You invest millions in constructing a property, only to see peeling paint, crumbling walls, and structural damage within the first two years. This is not bad luck; it is the result of using standard materials that cannot survive the harsh tropical environment.
To protect your investment, you must identify and defeat the five main threats: Mold, Termites, Rust, Fire, and Sagging. The only proven defense is using a specialized system of ASTM-certified Moisture Resistant Gypsum Board, Galvanized Steel Framing, and Fire-Rated partitions that are engineered to withstand Guyana’s specific climate challenges.

I have inspected countless buildings across the Caribbean. The story is always the same. A contractor tries to save money by using untreated wood or standard "white board" in the wrong place. Six months later, the owner calls me asking how to fix the mess.
How Do You Stop Black Mold from Taking Over Your Walls?
Humidity in Georgetown averages over 80%, turning standard drywall into a breeding ground for toxic black mold that ruins your paint and endangers your health.
The solution is strictly using Moisture Resistant (Green) Gypsum Board for all wet and semi-wet areas. This board features a silicone-treated core and chemically guarded paper that repels water vapor, preventing the moisture absorption that feeds mold spores and ensuring your family breathes clean air.

Let's dive deeper into the chemistry because this is where many people get cheated. Standard gypsum board is like a sponge. It loves water. In Guyana, even the air in your living room carries enough water to soften a cheap board over time.
Real Moisture Resistant Board (the Green one) is different. During our manufacturing process, we inject silicone oil directly into the gypsum slurry. We also treat the green face paper with fungicides. This creates a hydrophobic barrier.
You need to look for ASTM C1396 certification on the board edge. This standard guarantees that the water absorption is less than 5% by weight. If you buy a cheap "green board" without this stamp, it might just be normal board painted green. It will mold.
Where must you use this?
- Bathrooms & Kitchens: Mandatory.
- Laundry Rooms: Essential.
- Coastal Homes: Highly recommended for all walls due to salt air moisture.
Mold is not just ugly. It eats the paper liner of the board. Once the paper is eaten, the board crumbles. Using the right board is the cheapest health insurance you can buy.
Will Termites and Rust Eat Your Structure from the Inside?
Wooden studs are food for termites, and cheap metal studs turn to dust in the salty Atlantic breeze, leaving your walls with no support.
You must build with inorganic materials that pests cannot eat and weather cannot destroy. Galvanized Steel Keels (coated with Z275 Zinc) and Fiber Cement Boards are the ultimate termite-proof combination, offering a structural lifespan of over 50 years even in the most aggressive coastal conditions.

I started my career in the factory, so I know metals. In Guyana, you have two biological/chemical threats attacking your frame simultaneously.
First, Termites. They are relentless. If you use wood, you have to poison the ground. If you use Steel Keels, the termites hit a metal wall. They cannot bite it. Your structure is safe forever.
Second, Rust. This is the silent killer on the East Coast. The air contains salt. If you buy "cheap Chinese studs" with a thin zinc coating (Z40 or Z60), they will look fine today. But in two years, the salt eats the zinc, then the steel rusts, and your ceiling collapses.
At TRUSUS, we provide High-Zinc Coating (Z140 - Z275). The zinc sacrifices itself to protect the steel.
Comparison of Structural Lifespan in Guyana:
| Material System | Termite Risk | Rust Risk | Est. Lifespan |
|---|---|---|---|
| Untreated Pine | Very High | Low (Rot High) | 3-5 Years |
| Treated Lumber | Medium | Low (Rot Med) | 10-15 Years |
| Cheap Metal Stud | None | High (Rapid Rust) | 5-8 Years |
| TRUSUS Galv. Steel | None | Very Low | 50+ Years |
Do not build a permanent house with temporary materials.
Is Your Building Safe from Fire Hazards?
Electrical faults are common, and standard plywood partitions act as fuel, allowing fire to spread rapidly through a property.
For commercial buildings, hotels, and safe homes, you must install Fire Rated (Pink) Gypsum Board. This board is reinforced with fiberglass and chemically combined water crystals (calcium sulfate dihydrate) that release steam when heated, acting as a built-in sprinkler system to hold back flames for up to 4 hours.

Fire safety is often ignored in residential construction until it is too late. But for B-End clients (Contractors building offices, stores, or hotels), this is a legal requirement.
The Fire Rated Board (Pink face) is an engineering marvel.
- The Core: It is denser. We add glass fibers to the mix. When a normal board burns, the gypsum crumbles and the board falls out of the frame, letting the fire pass. The glass fibers hold the Pink Board together even when it is charred. It stays in place.
- The Effect: It blocks the fire path. A 5/8" (15.9mm) Fire Rated board on both sides of a Metal Stud wall can stop a fire for 1 to 2 hours. This gives people time to escape and firemen time to arrive.
Application Scenarios in Georgetown:
- Commercial Kitchens: Use Fire Board on the serving wall.
- Server Rooms: Protect your expensive data equipment.
- Stairwells: This is the escape route. It must be fire-rated.
- Party Walls: The wall between two apartments. If your neighbor has a fire, you stay safe.
We supply the Full Fire-Stop System: The Pink Board, the Steel Stud (which doesn't burn), and the Fire Joint Compound.
Conclusion
Defeat mold, termites, and fire by using Green Board, Galvanized Steel, and Pink Board. A specialized system is your best defense.
