Kalka + Partner & Woodworker Friends Ltd. – Separating Fact from Fiction in Sustainable Construction
Rwanda’s construction sector is booming, driven by urbanization, infrastructure development, and a commitment to sustainability. Yet, despite timber’s proven potential, misconceptions persist about its strength, safety, and suitability for Rwanda’s climate. At Kalka + Partner & Woodworker Friends Ltd., we’re here to set the record straight. From termite resistance to fire safety, let’s dismantle the myths holding back Rwanda’s timber revolution—and showcase why eucalyptus, Muvula, and teak are smarter, safer, and more sustainable than you’ve been led to believe.
Myth 1: “Timber Isn’t Durable in Rwanda’s Climate”
Truth: When properly treated, timber rivals—and often surpasses—concrete and steel in longevity.
Rwanda’s climate, with its heavy rains, demands materials that withstand moisture and temperature fluctuations. Timber, when dried and treated, excels in these conditions:
- Eucalyptus: Drying reduces moisture content to 13 to 20 percent, preventing warping and decay. Treated eucalyptus beams and doors are trusted in projects from Kigali’s suburbs to rural cooperatives.
- Teak: Renowned globally for durability, teak thrives in humid environments, aging gracefully without losing structural integrity. – Kalka’s teak is imported and kin-dried in the factory to 15 percent and reduced even more in our storage in Gikomero to its natural moisture content.
Key Takeaway: Durability hinges on proper processing. Our timber undergoes rigorous drying and non-toxic treatments to meet Rwanda Standards Board guidelines, ensuring decades of reliable performance.
Myth 2: “Timber Attracts Termites and Pests”
Truth: Modern treatments and natural properties make timber a termite-resistant powerhouse. Like all building materials, periodic maintenance is key — but the good news is: termite protection is easy to renew when needed.
Termites plague Rwanda’s buildings, but timber is not the enemy—poorly treated timber is. Here’s how we protect our materials:
- Borate Treatments: For eucalyptus and teak, borate-based preservatives penetrate deep into the wood, creating a barrier against termites and beetles.
- Regular Maintenance: Simple practices like sealing joints and avoiding soil contact further mitigate risks.
Myth 3: “Timber is a Fire Hazard”
Truth: Engineered timber meets rigorous fire safety standards—often outperforming steel.
While wood is combustible, modern techniques enhance its fire resistance:
- Fire-Retardant Coatings: Intumescent paints and sprays char on exposure to flames, slowing combustion.
- Mass Timber Construction: Thick cross-laminated timber (CLT) panels burn slowly and predictably, maintaining structural integrity longer than steel, which can warp under high heat.
- Compliance: Our designs adhere to Rwanda Fire and Rescue Force codes, ensuring safe escape routes and compartmentalization.
Did You Know? Timber’s charring effect creates a protective layer, allowing it to retain strength even during fires.
Myth 4: “Timber is More Expensive Than Concrete”
Truth: Timber offers long-term savings through speed, sustainability, and lower maintenance.
While upfront costs vary, timber’s advantages shine over time:
- Speed = Savings: Prefabricated timber structures reduce labor and financing costs by shortening project timelines.
- Energy Efficiency: Timber’s natural insulation lowers HVAC expenses.
- Sustainability Incentives: Align with Rwanda’s Green City Kigali goals to access grants and investor partnerships.
Cost Comparison:
- Eucalyptus: Affordable and locally abundant, ideal for budget-conscious housing.
- Teak: A premium option with an unmatched lifespan, reducing replacement costs.
The Timber Advantage: Rwanda’s Sustainable Future
Rwanda’s Vision 2050 and climate goals demand materials that balance innovation and tradition. Timber delivers:
- Carbon Sequestration: Every cubic meter of timber stores 1 ton of CO₂, combatting climate change.
- Local Empowerment: Sourcing eucalyptus supports Rwandan forestry and artisans.
- Design Freedom: From curved roofs in Kigali’s business district to rustic lodges in Volcanoes National Park, timber enables bold, culturally resonant architecture.
Call to Action: Build with Confidence
Don’t let myths dictate your choices. Whether you’re constructing a family home, a community center, or a commercial complex, timber offers strength, safety, and sustainability.
