Fire resistance
Although it is a flammable material, glulam has excellent fire-resistant properties. It chars evenly as there are no cracks or gaps, and the charred layer forms a protective coating that delays the flames from spreading inwards. Whilst the burning does reduce the mass of the material, it does not impair its mechanical properties. Compared to other materials, wood does not suddenly give way, instead the construction breaks down slowly and gradually.
Earthquake resistance
The structural and dimensional stability of glulam makes it highly resistant to the forces of an earthquake. The material is five times lighter than reinforced concrete and fifteen times as light as steel. Due to its low relative weight and extraordinary mechanical resistance, the forces exerted during an earthquake can be significantly absorbed.
