What is heavy timber framing?

Heavy timber framing is a centuries-old construction technique where massive solid timber posts and beams form the load-bearing skeleton of the building. The timbers are joined using traditional wooden joinery (mortise and tenon joints) locked with hardwood pegs, without metal connectors.

How does timber framing differ from light wood framing or CLT?

Timber framing uses 100% natural, heavy solid timber rather than glued plywood or composite panels (CLT). Structural load capacity is provided by massive wooden columns and beams that often remain beautifully exposed in both interior and exterior.

What insulation is used in timber frame buildings?

Modern timber frame structures use natural and breathable insulation such as wood fiberwool, mineral wool, or traditional materials like clay and straw, providing outstanding thermal performance and indoor microclimate.

Core Concept

What is Timber Framing?

Heavy timber framing is an ancient and sustainable building method where massive solid timber posts and beams form the load-bearing framework of the structure.

🪵

100% Solid Heavy Timber

We use natural solid timber — load-bearing members are never replaced with glued plywood or synthetic composites (such as CLT).

📐

Traditional Joinery & Wooden Pegs

The structural frame consists of vertical, horizontal, and diagonal timber beams connected with hand-carved mortise-and-tenon joints secured by hardwood pegs.

🍃

Ecological & Breathable Envelope

Wall cavities are filled with modern wood fiber, mineral wool, or traditional clay and straw insulation, ensuring exceptional thermal comfort and healthy microclimate.

Knowledge & Insights

Frequently Asked Questions

Everything about timber framing, material selection, longevity, and construction workflow.

Timber framing is a classic, centuries-tested construction method where heavy solid timber posts and beams bear the structural load. Unlike conventional stud framing or glued panels, it relies on natural solid timber and mortise-and-tenon joints locked with wooden pegs.

When properly crafted and protected from moisture, a timber frame building easily lasts for centuries. In Europe and Japan, timber frame structures built 400 to 700 years ago are still standing strong. Wooden pegs never rust and naturally adjust with timber movement.

Yes, absolutely. Modern timber frames are wrapped in high-performance eco-friendly insulation (wood fiber, mineral wool, or clay-straw), delivering exceptional insulation values and an optimal indoor microclimate.

Yes! We specialize in restoring historic timber structures, replacing decayed beams with matching solid timber, and preserving authentic joinery techniques.
