Presenting..SustainableUnique Novel Better Aesthetic Nanotechnology

SUN BAN

Benefits of SUNBAN Glass for my home?Welcome to the Future..

Sun Ban helpsCut Heat Keeping interiors Cool reducing the cooling requirement and costs Eliminate the use of Artificial lights during daytime allowing penetration of natural light Outdoor Privacy Control Better Interiors - focusing on Occupants comfort Protection from UV rays Maintain unmatched Aesthetics

Advantage Sun Ban

Freedom from Heat Freedom from Mounting Energy Bills Freedom from Non Aesthetic Facades Freedom from Glare Freedom from UV radiation

Sun Ban : Manufacturing Technology

Coating applied under vacuum by Magnetron sputtering process Physical Vapour Deposition during Glass Manufacturing (Online)

State of the Art Nanotechnology based coating process Multipurpose products for better living Products manufactured that can save upto 70% of Energy Consumption Robust and Durable

Freedom from Heat

Heat gain due to Direct solar radiation 1#

directly + re-emitted energy = Solar Factor 2#

Lower Heat into the interiors due to Lowest Solar Factor * in their class

reflected energy re-emitted energy Cuts down heat upto 80%

Lets see some Calculations..

Situation 1 : Non Air conditioned Building

Power Rating : 1 starClear Glass 6mm

Solar Factor 0.82U value 5.7 W/SqmK

Considering the performance of 3 star glazingSolar Factor 0.30 U value 5.7 W/Sqmk

Non Air conditioned Building Contd..Considering a typical residential plot with 1,500sqft floor area 250sqft of glass usage When the window is closed there results constant heat gain with indoor temperature rising During typical summer period Clear Glass contributes to 3 C rise in temperature in 5hrs 3 star rated glass results in only 1.3C rise in temperature in 5hrs Benefits Better thermal comfort Time required for cooling of space is reduced Indoor occupants comfort

Situation 2 : Air conditioned Building

Case StudyConsider a typical Residential Building in Mumbai7 floors-14 flats Glaze Area-Window

Go Green

Do your little bit to the planet ! Every reduction in Unit of electricity (KwHr) means 1.0 kg (CO2e) per kWh : Lower Carbon Footprint Every reduction in a single KWH, 1 Kg of CO2 emission is prevented In above case every family, cares for EARTH by saving 1.65 tonne of carbon emission by using 4 star rated glass In above case every family, cares for EARTH by saving 0.80 tonne of carbon emission by using 3 star rated glass

Freedom from UV rays

UV Radiation causes : Harmful Skin Ailments Fading of Curtains and Furniture

Fading of Rug due to exposure to UV rays

Sun Ban glass cuts upto 96% of UV radiation more when compared to Clear Glass !

What do you get ? Use of Sun Ban glass in your project results in :Higher realization for your property Payback period to the end customer < 2 years Lower maintenance costs at the customers end
