Timber framed construction was by far the most common method of construction in these continents due to the vast amount of timber that was readily available. Traditionally, the construction of timber framed buildings relied heavily…show more content…
The joists are also made to measure in a factory environment, (similar to pre-fab construction) this means that when they arrive on site they are ready to fit. This is a great advantage over a traditional solid timber beam as these beams would arrive on site from the timber suppliers and would need to be cut to length and adjusted in order to fit, this process produces a lot of waste material from the off cuts of wood, however this waste could then be used for the cross bracing of the joists or re used in other parts of the building such as using them for glue blocks during the production of the stair case. Although it may seem that the eco-joists are the clear choice when looking for suitable methods of supporting a floor, it would be worth noting that these joists would have a higher initial cost when compared to traditional timber joists (usually 6”x2” rough cut timber) as the eco-joist are manufactured items which means that the manufacturer would have apportioned a production cost into the final price of the item. For that reason alone, it would be worth comparing the two methods in financial terms in order to see which one will prove to be the best value for money in both the immediate and long term. It is also worth noting that eco-joists cannot just be “knocked up” by a local Joinery company, they need in depth calculations in order to work out factors such as the bending moment which then dictate the design and spacing of the joists, again
