WHY TIMBER?
High Quality
- Superior Acoustics - Aestheticsal- Energy Efficient - Good Fire Resistance
- Low Cost - Speed of Erection - Almost no Maintenance.
Thermal properties:
Wood is 2 times better than concrete, 400 times better than steel and
1,500 times better than aluminum.
THE MYTHS
Wood Easily
Rots!
No, the design has to provide good ventilation to allow the timber to
breathe. Internal wood should be kept dry. The moisture content should
not exceed 20%. External wood can be exposed to the weather but good drainage
is of importance. Many examples of mediaeval houses and barns still exist
today.
Wood Burns
Easily!
No, glue laminated structures have a high resistance to and a predictable
performance in fire. Scandinavian redwood chars at a slow rate of 40mm
per hour, thus creating a fire protective barrier and more importantly
retains its structural integrity.
Wood is
expensive!
No, a direct comparison shows that laminated structures are less expensive
than steel or concrete structures. The lower weight of laminated timber
also make savings on foundations, transport and erection time.
Wood Lacks
Strength!
No, a structural steel beam is about 20% heavier and reinforced concrete
beam 600% heavier than the equivalent laminated timber beam. With minimal
maintenance required and use in the correct environment the expected life
span is virtually unlimited.
Wood has
limited span!
No, the arched structure is the least complicated and strongest shape.
This shape has been used frequently for large spans in Europe, Russia
and USA.
E.g. spans: Littledown, Bournemouth 48m
Utopia Pavilion, Expo 98, Lisbon 119m
Wood usage
depletes forests!
No, our laminated structures are made from sustainable timber from Finland,
Sweden and Norway.
Example: In Finland 65% of the area is forest (20.1 million hectares).
Forests in Finland increase on average 13.8 million m3 per year or 5,50000
hectares per year. Legislation in Finland demands the planting of 2 new
trees for every felled.
