Titanium

Appearance Other finishes Other characteristics Documents Representative works

Appearance

The natural colour of titanium is light metal silver, with quite a shiny and reflective surface.

As opposed to almost all the other metals we work with, except for stainless steel, titanium keeps its shine. In addition, to give even more character to the work, the oxide layer plays with the light giving the effect of interference that changes the shade of its colour according to where we are looking at it from.

Crimped systems are normally used for lower thicknesses than copper and zinc and this gives it the characteristic waves or "gables" that are typical of this metal. Greater thicknesses can be used in panel systems for facades that reduce or eliminate this feature.

Other finishes

There are several very attractive finishes obtained by giving different textures to the surface or anodising it at different thicknesses. The textures can increase the shine on its surface or almost completely eliminate it. There are textures in between with more or less shine and surfaces with different macro roughness.

By means of anodising at different thicknesses, it is possible to get different colours due to the light interference effect. Greens, blues and browns are the possible shades.

For more information on the different finishes available in zinc, refer to the other files on our metals.

Other characteristics

Titanium has several qualities that make it particularly appropriate for covering roofs and facades:

Resistance to corrosion without torque and therefore with unlimited durability estimated at over 100 years in all atmospheres
It does not require any maintenance or cleaning
Very light and strong
Low thermal dilation coefficient
Not toxic, it does not affect the environment
It is compatible with other metals usually used in building, such as steel and aluminium

Nevertheless, we have to pay attention to the following aspects:

The initial cost is high
It is not possible to weld this metal with tin. Other solutions (crimped joints, glued joins, etc.) are possible

Titanium can be used in the following systems of ours:

Seam (roof and facade)
Bar joint
Butt joint (scales)
Facade panels
Cassette panels

The following materials can be used as support:

Water-repellent board, 19 mm thick
Rigid insulation
Plywood board
Corrugated metal
Masonry on facades whenever this is flat and smooth

The following separating sheets/ventilation membranes can be used

Breathable sheets
Micro-ventilation membranes
Geo-textiles
Impermeable sheets
