What is a Green Building? "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?Green building (also known as green construction or sustainablebuilding) is the practice of creating structures and using processes thatare environmentally responsible and resource-efficient throughout abuildings life-cycle: • from siting to design, • construction, • operation, • maintenance, • renovation, and • deconstruction The Blu Homes mkSolaire, a green building designed by Michelle Kaufmann 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 credits are weighted to reflecttheir potential environmental impactsAdditionally, 10 bonus credits are available, four of which address regionally specificenvironmental issues. A project must satisfy all prerequisites and earn a minimumnumber of points to be certified.

Preference for an insulation material among the givenoptions 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 made from abundantly available raw materials (minerals) on the earth 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) Environment Friendly – Zero GWP and Zero ODP Can meet almost all application requirements in the buildingAnd moreover “Buy one and get one free” rule is applicable due to their dualperformances ( Acoustic and Thermal Insulation)
