3 in 1 treatment for roof terraces

               3 in 1 TREAMENT FOR  ROOF 
                       (Lightweight + Thermal Insulation + Waterproofing)

Temperatures could nudge 45 to 47 degrees Celsius in large swathes of north and northwest India for the rest of the week, the weather office has forecast, before conditions ease slightly with the onset of monsoon down south.

The India Meteorological Department (IMD) issued “heat wave to severe heat wave” warnings for parts of Uttar Pradesh, Haryana, Rajasthan, Gujarat, Madhya Pradesh and Delhi, which are already baking in early-summer heat this year. Maximum temperatures could touch 45-47 degrees in a severe heat wave condition.

“These conditions are likely to spread … during May 17-21. They are likely to abate gradually during the remaining part of May,” the IMD said late Monday.


Today Ahmedabad touched almost 50'C 

Roof / Terraces   by  defination is the covering on the uppermost part of a building structure . A roof protects the building and its contents from the rain / heat /earth quake effects of all climate  primarily in India against rains, heat ,cold, .  
The characteristics of a roof are dependent upon the purpose / climatic zones  of the building that it covers, the available roofing materials and the local traditions of construction and wider concepts of architects designs and practice and , may also be governed by local or national laws ( still yet to amend)
 GBC INDIA ,are  innovators , developers and makers of green products , crafted  on the basic principles of sustainability i.e modernizing traditional  methods .

We are  backed by 15 years  as an water proofers  , that enhances our claim to’know the roof better ‘and first to spearhead making 'INSULITTE' , utilizing agro waste like rice husk ash
 

Our focus is on roof/over deck applications ,been a maximum  heat gain area  and vulnerable during rains so designing over deck insulation applications , water proofing cannot be ignored 

roof insulation concrete 

                                                                                       

Below are the conclusion based on our practical experiences are : 
Designing   for any heat /roof  insulation  the fundamental is to create an air space/cavities within composites layers  resulting in  light weight , and that is reversed in water proofing  where the same cavities  has to be blocked
Existing  insulation  techniques  using minerals like vermiculite / perlite / insulitte etc.  in expanded form are very fluffy /feathery /light in physical appearance   , and when  mixed with cement/sand/lime etc., gives excellent insulation values which aids in energy conservations  , are low  compressive strength but at the same time creates unnecessary dead load due to huge water absorption capacities i.e ranging from  70% -90% of its volume , carrying  very low vapor permeability values/moisture  (i.e to escape water in the form of vapor / unbreathable ) from that composites layer    , since  it has to be  covered with HDPE/BITUMEN/CONCRETE PLASTER   etc., for protection against  water  entrapped from top layer

Traditionally  proven over deck  techniques   are with brickbat / integral/brick jelly / mud phuska   , since it is  applied  for insulation cum water proofing  having good compressive strength

But in recent years have failed due reasons like dead loads/quality available / expert applicator/ building heights  / labour crisis etc.,

So concluding   , demand have arise for over deck design that shall comprise of light by weight  , waterproofing having sufficient compressive strength

heat insulation aggregates 

lightweight aggregates for insulation concrete 

nodullär has been introduced  to fulfill all the  the above criteria

nodullär aggregates are manufactured   using sedimentary clay  as a major ingredient , that are deposited  in natural form which is rich in silica ,This natural clay  has cellular structure inside , are pelletized and  processed  resulting in light , porous ,  aerated modules with a tough outer shell aggregates 

 In addition each of the  nodullär  aggregates/ balls due to its normal round shape also acts to form of geometric barrier which helps to displace and irradiates heat over a larger surface area the air entrapped thus , reduces the rate of heat  transfer compared with dense, natural aggregates.   .

Therefore ,   nodullär –a light weight aggregates  improves  thermal / heat insulation , waterproofing etc. m enhanced with compressive strength in buildings and structures.

GBC INDIA are suppliers for light weight aggregates in India like LECA , expanded clay , expanded aggregates
