Products » Roof Insulation » Porosil


POROSIL is a light weight insulating aggregate insulation which is to be mixed with cement. It protects the building from the intensity of direct solar heat and lowers the room temperature by a minimum 6-8 degree and makes the covered area very pleasant. This product brings you to a new, simplified and cost effective solution for keeping building permanently cool structures as per your satisfaction.

For slabs:

  • POROSIL is to be mixed with cement in the proportion of 2 bags of POROSIL and 1 bag of cement requisite water is then to be added to the dry mixture.
  • Screeding is done to the desired thickness
  • The surface where it is to be applied should be free from dust particles, stones etc.
  • The mixture should be laid over the RCC slab in required thickness without applying external pressure.
  • Water curing is required twice a day in winters and thrice a day in summers for 4 to 6 days.
  • Waterproofing can be done over the POROSIL layers and more layers of IPS or tilling can be done

For Loose filling in Hollow Block Wall/Cavity Wall:

  • POROSIL to be poured from the bag into the cavity of concrete block wall directly.
  • Pours may be made at any convenient interval
  • The height of any pour shall not exceed 20 feet
  • Rodding or tamping is not necessary
  • After pouring into cores of cavity walls/hollow block construction it makes an uniform component, non-setting insulating barrier against the transmission of heat and sound
