The timber arrived at the end of last week for the three large roof trusses in the new extension. These will be constructed in a local industrial unit. The timbers will then be individually numbered and the whole thing taken apart and brought onto site. This means that it will take a fraction of the time to construct the roof on site. Which in turn means that it is less likely to get exposed to the weather (important at this time of the year).
The roof trusses are constructed from green oak. This wood is heavy to lift and easily marks if it gets wet.
It will require lifting equipment to manoeuvre the large pieces of timber into position. The tie beams in particular are very heavy due to the size of the timber. Another reason for constructing the roof trusses off site initially.
Very large sections of green oak will be used to construct the three large roof trusses.
More timber for the roof trusses.
These are the horizontal beams (refered to as “tie beams”) for the three roof trusses.
