Load Bearing Floor Insulation

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.

Load bearing floor insulation.

It is comprised of an extruded polystyrene closed cell foam panel with continuous skin face and back surfaces. The load bearing walls and the floor slab of the building sit on top of an eps layer typically with trenches cut into the insulation near the perimeters for a ring beam of reinforced concrete to support the external walls though the entire floor contributes to supporting the weight of the building. 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. Joints in ground bearing slabs tend to be present for two reasons.

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. 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. 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. Wearing concrete slab the floor slab that contains either a square fabric mesh or fibres.

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. Styrofoam brand highload extruded polystyrene foam insulation is a closed cell foam insulation designed for use in runways and other heavy weight infrastructure. Vibration insulation materials performance of most of the modern residential and office buildings is impossible without life supporting engineering equipment. Owens corning s patented hydrovac.

Bearing assembly see fig 1 2. Eps can be a cost effective alternative to pir for floor insulation and the same thermal performance can be achieved with increased thickness.
