Load Bearing Floor Insulation

Floorboard insulation after discussing the different types of insulation material commonly specified in ground floor constructions in this previous blog we explained why it s important not to assume that all insulation performs the same way with regard to thermal performance and loadbearing capacity.

Load bearing floor insulation.

Point loads are spread by the layers above the insulation so that the load acting on the insulation is lower than the load applied to the floor surface. Owens corning foamular 400 600 1000 extruded polystyrene insulation is a high density insulation designed for use in engineered applications requiring additional load bearing capability. In a solid or ground bearing because it is continuously supported by the ground across its whole area concrete floor the choice of insulation position relative to the concrete slab is commonly linked to the building s heating system. Conditioning and ventilation systems backup power sources elevators and other devices are the source of low frequency mechanical vibrations transmitted by load bearing structures of a.

Styrofoam brand highload extruded polystyrene foam insulation is a closed cell foam insulation designed for use in runways and other heavy weight infrastructure. Timber flooring on polyethylene slip sheet insulating a solid ground floor below the ground bearing concrete slab can be done using either pir insulation boards or eps insulation boards. Levelling plates to assist a fast and accurate installation fail safes lateral restraints load spreading to ensure the load from the structure is evenly spread over the entire area of the isolation bearings disproportionate collapse measures such as acoustically isolated. It is comprised of an extruded polystyrene closed cell foam panel with continuous skin face and back surfaces.

Vibration insulation materials performance of most of the modern residential and office buildings is impossible without life supporting engineering equipment. A point load applied to a floor where the insulation is positioned below a thin screed will result in a higher applied load on the insulation than where the insulation was positioned below a thicker floor slab because the load is bearing on a smaller area of insulation under the screed. Bearing assembly see fig 1 2. Wearing concrete slab the floor slab that contains either a square fabric mesh or fibres.

Eps can be a cost effective alternative to pir for floor insulation and the same thermal performance can be achieved with increased thickness. Insulation required for thermally sensitive environments which typically require ultra flat and level surfaces.
