Which windows are suitable for tropical African countries?

best windows for tropical African countries

💡 DID YOU KNOW?

In most buildings across tropical African countries, the wrong choice of windows reduce natural airflow by 50%.

And yet, in our tropical climates, air circulation isn’t optional it’s essential.

🌬 Natural ventilation: A must-have, not a luxury
In hot and humid climates:

Sweat doesn’t evaporate without airflow ➜ discomfort, tiredness, headaches.

Humidity stays trapped ➜ mold, bacteria, bad smells which creates an environment conducive to mosquitoes, and breathing problems

Stale air ➜ harder to focus, lower productivity.

So what’s the solution?

Windows that really let the air flow.

Here’s how different windows rank for ventilation:

✅ Casement windows ➜ 90% airflow

✅ Louver (jalousie) windows ➜ 75% airflow (Some people think of them as poor people's windows, but they're very effective.)

✅ Awning windows ➜ 75% airflow

❌ Sliding windows ➜ Only 45% airflow!

And yet… sliding windows are everywhere. Why?
They seem nice, are easy to install, and often cheaper…
But they cost a lot in comfort and health.

💡 My top recommendations for tropical homes:

✅ Louver windows – Best for tropical climates: adjustable, let air in even during rain, and easy to clean.
✅ Casement windows – Perfect for maximum ventilation.

✅ Awning windows – Great for high places or keeping windows open when it rains.

Honestly, I’ve never felt comfortable in poorly ventilated spaces since I was a kid.

That’s why, as an architect, natural airflow is a priority in every project I design.

👉 Changing your windows is an investment in your health, comfort… and energy.
