Rigid Slabs

High density ARW Rigid Slabs faced with Polyethylene bags is ideal for thermal and acoustical insulation of the concrete roof buildings & internal acoustic lining

ARW Rigid Slabs are produced in high density with the following specifications:

Burkani Rigid Slabs are applied in the following applications:

Roof Thermal Insulation

High density ARW Rigid Slabs faced with Polyethylene bags is ideal for thermal and acoustical insulation of the concrete roof buildings. Rigid Panels are placed above the roof and below the reinforced concrete screen. The rigidity of the slabs will resist the compression of the panels from screen load. While Polyethylene bag will protect the slabs from water and wet concrete penetration.

Acoustic Insulation

High density ARW slabs are recommended for acoustic insulation purposes in the construction sectors. ARW slabs are used to modify the everberation time of the place due to its high sound absorption by mounting ARW slabs to the internal wall surface of the room. ARW Panels are used also to improve the efficiency of the wall to reduce the sound transmission through it. ARW slabs are applied either un-faced or faced with fiber glass veils. ARW slabs are efficaciously applied on TV and broadcasting studios, conference halls, Electrical generators enclosures, or rooms.

Internal Acoustic Lining

ARW slabs are used as acoustic lining of the cooling & heating ducts to reduce the noise level by absorbing the sound of the airflow through the ducts. 25-30 mm thickness of the slabs is suitable to absorb the sound of high frequency due to its short wave length.
