EPS is approximately 98% air captured within a 2% cellular matrix, this causes it to be very lightweight resulting in lower loads applied to the foundation. It has a densities of between 10 and 35kg/m which allows for light and safe construction work. Due to its low weight it is very easy to transport, thus saving a lot of fuel, therby lowering costs. The low weight of EPS also makes it easy to handle on site, especially considering that the lifting of materials with heavy machinery has become an increasingly important health and safety issue in the construction industry.

These EPS insulating boards can be laid relatively quickly and in any weather conditions, as it is unaffected by moisture. An exceptional characteristic of EPS is its weight to insulating performance. This is of major …show more content…
They can be used for numerous applications, such as exterior and interior wall, roof insulation, flooring and foundation systems.
One of the major advantages of SIPs are the financial benefits. Due to the fact that the composite material used between the boards can be cheaply produced as well as the possibility of using recycled material. Unfortunately the owner of the house would not give me the total costs of the project however the chief contractor told me that the building of this size would cost roughly 15% more and taken 3 months longer, if traditional bricks and cement was used.
Another important benefit of these SIPs is that they can be manufactured offsite allowing for the building process to go much quicker. This means that entire building can be built offsite, thereby only requiring assembly. Pieces can also be standardised allowing for changes to be made relatively easily even once the project has started. This shortens the building time by several months resulting in cheaper labor
