Over Deck Roof Insulation with KOOLTILEs


Insulated Roof above Styro Stone Walls

After concrete pouring into the Styro Stone walls is over, the next stage is construction of a regular RCC roof slab. You have to insulate this as well.

Why should you have an externally insulated roof?

  • insulation from outside protects not only the roof slab but also the waterproofing layer
  • the roofing elements undergo a daily cycle of contraction-expansion due to the solar heat, causing cracks, which if untreated, damages your structure & leads to unhealthy damp to seep inside your rooms
  • so the insulation layer prevents the 'weathering out' of the roof and adds to the life of your construction,
  • thus, it saves you from the periodic hassles of costly repair work on the roof.

    What should you do for external insulation on your roof?

    The most effective method is with a suitable product such as KOOLTILE.
