COST AND TIME SAVING SOLUTION
|
|
 |
speed of erection - O'Reilly hollowcore floors can be installed up to 500 square metres per day, saving time on site and reducing overall program of works |
|
reduced weight - O'Reilly hollowcore floors have polystyrene infill reducing overall weight of floors; this means reduced loads transferred to the foundations and smaller foundation size is required |
|
no open voids - O'Reilly hollowcore floors have solid ends; this eliminates the risk of water or other contamination in cores; no additional work on site is required to close open cores |
|
no drilling and cutting - all service openings can be easily formed in hollowcore floor slabs at production stage; slabs are manufactured up to exact site dimensions |
|
|
BETTER THERMAL PROPERTIES
|
|
|
O'Reilly pre-stressed Hollowcore floor units have better thermal properties than slabs with open hollow voids due to completely closed cores filled with polystyrene. The air movement in traditional hollowcore slabs reduces their thermal performance.

|
here is a comparision of U-value between our standard Hollowcore slabs and the same slabs with open voids; lover U-value means better thermal insulation

The termal performance of standard O'Reilly Hollowcore floor slabs is 25% better in average comparing to the same slabs with open voids.
|
|
|
BETTER FIRE RESISTANCE
|
|
|
standard O'Reilly Concrete pre-stressed hollowcore floor units have a minimum fire rating of 1 hour
|
|
unlike extruded units, our units have solid concrete ends which further improves fire retardation
|
|
|
BETTER SOUND RESISTANCE
|
|
|
O'Reilly Concrete hollowcore floor units have a high resistance to both airborne noises and impact sounds
|
|
because our cores are made using polystyrene formers, our units are also the perfect acoustic barrier between floors such as in apartment buildings
|
|
|
STRUCTURAL EFFICIENCY
|
|
|
the use of high strength concrete and pre-stressed steel offers better span to depth ratio and strengths far greater than the traditional floor systems
|
|
improved shear resistance gives additional safety at construction phase and in use
|
|
special design and construction of longitudinal joints between slabs allows for composite action of slabs and transfer point loads and line loads between adjacent slabs
