Role of insulationin enhancing
Green Building Rating
"A green building is one which uses less water, optimises energy
efficiency, conserves natural resources, generates less waste
and provides healthier spaces for occupants, as compared to a
conventional building."
What is a Green Building?
The Blu Homes mkSolaire, a green building designed by Michelle Kaufmann
What is a Green Building?Green building (also known as green construction or sustainable building ) is the practice of creating structures and using processes that are environmentally responsible and resource-efficient throughout a building's life-cycle:
• from siting to design,
• construction,
• operation,
• maintenance,
• renovation, and
• deconstruction
This practice expands and complements the classical building design concerns of economy, utility, durability, and comfort

LEED points are awarded on a 100-point scale, and c redits are weighted to reflect their potential environmental impacts
Additionally, 10 bonus credits are available, four of which address regionally specific environmental issues. A project must satisfy all pr erequisites and earn a minimum number of points to be certified.
100 Possible Points + 10 Possible Points for Innovation / Regional Priority
• Certified: 40 - 49 points
• Silver: 50 - 59 points
• Gold: 60 - 79 points
• Platinum: 80 + points

Some Recent Fire Incidents in GCC
Firefighters injured in Doha airport project blaze
� Fire broke out at the residential Al TayerTower near Al Nahda Park in Sharjah on Saturday morning at around 2:30am . Hundreds of families have been displaced.
� Firefighters battled for about five hours to control the flames that engulfed the building, witnesses said.
� The cause of the blaze was suspected due to combustible insulation panels used in the building.

Preference for an insulation material among the given
options shall be based on
• Usage of Raw material
• Handling, transportation and storage
• Application Requirement
• Safe to Human
• Throughout Life Performances (Aging effect)
• Emissions after in use
• Fire Class
• Behaviour during fire
• Impact on environment (ODP & GWP)
Let’s go with confidence !
By opting Mineral Wool Insulation (Glass wool & Rock wool)
Because Mineral Wool (Glass wool & Rock wool) Insulation
� Are available as flexible, semi rigid and rigid
� Are light in weight and compressible
� Are suitable in wide range of temperature from – 200 oC to + 800 oC
� Does not promote growth of mould, bacteria and fungus
� Does not show any aging
� Are Fire Safe; Resist the fire and achieve highest class of fire safety
(Euro Class A1)
� Can meet almost all application requirements in the building
� Are made from abundantly available raw materials (minerals) on the earth
And moreover “Buy one and get one free” rule is applicable due to their dual
performances ( Acoustic and Thermal Insulation)
� Environment Friendly – Zero GWP and Zero ODP
