Fenestration - Divya BT, Archemist Architects
he design and placement of windows in a building is called fenestration. Windows are one of the most important features in a building; the primary functions being that of light and ventilation. They also play a key role in enhancing the beauty and aesthetics of external facades and also largely influence the quality of the internal atmosphere. It is indeed one of the elements in architecture one simply cannot do without in a building.
As we can see windows not only serve as features for light and ventilation, but are equipped to do a lot more! Technology has taken over and with windows offering so much, it definitely is a feature one should not neglect. Do not hesitate to invest in it, as it pays back in providing a better quality of life in a building. About the Author
The fenestration industry is therefore a thriving one; and where there is competition, there is innovation. With every building element constantly evolving to meet with the future needs, changing demands have dramatically changed how builders look at windows and skylights. The fenestration product industry is also breaking out of its old moulds and adopting a wide array of new design and technologies.
Safety Windows: Gone are the days where security grills ruined the panoramas from a large window. Toughened and laminated glass in the windows is being used to provide additional safety. Toughened safety glass has undergone a heat treatment to increase its overall strength. Generally it is 5 times stronger than normal glass. Laminated glass is a glass sandwich with a single plastic film in between, so even if the Divya BT, Co-founder & Principal Architect at Archemist Architects. Archemist glass breaks into pieces, they remain adhered to the film avoiding potential cuts and Architects was started as a collaborative architecture practice by an architect couple injuries as a result of broken glass. Divya and Yogesh. They share a common love for architecture and innovation in construction. The architects bring in their expertise in sustainable design methodolSound Proof Windows: Now isn’t it a boon in the noisy city to come home to ogies in combination with construction management which is very essential in any some peace and quiet. Sound Proof windows are engineered with features that sub- building design. The mantra they follow is, ’Architecture should be innovative, easy stantially-reduce the ingress of outside noise levels. The windows are double sealed on the conscious and easy on the pocket.’ with EDPM gaskets, steel reinforced with a multi chambered and fusion welded www.archemistarchitects.com frame ensuring no gaps remain anywhere. Special silicon sealants are filled in the gaps between the windows and the walls. Multipoint locking system ensure tight shutting Image source: http://robin-safuddin.deviantart.com/art/eset-robot-logon-267769672 of shutters and with an addition of double or triple glazing, super insulation from up to 45decibels can be achieved! Weather Proof Windows: Heavy lashing rain, torrential winds and rising levels
of pollutants and dust can really pose a problem. Thus some leading UPVC window manufacturers have stepped up to offer a solution to the Indian weather conditions. Their special UV resistant UPVC blend with titanium dioxide, offer stable colour all through intense UV exposure for years and do not require paint or polish. Steel reinforced to frames and sashes provide a tough exterior to handle heavy winds. Special rain track mechanisms make the windows monsoon resistant by keeping the rain water out along with dust and pollutants.
Self-cleaning Windows: Now did we read that right? Well self-cleaning glass
does not need to be cleaned as frequently as normal glass. However it is not 100% maintenance free. A transparent coating on the outside of the glass harnesses the power of both sun and rain to efficiently remove dirt and grime. Exposure to the UV rays present in daylight triggers the decomposition of organic dirt and prevents mineral dirt from adhering to the surface of the glass. It also turns it “hydrophilic” meaning that when it rains the water sheets across the glass, without forming droplets, rinsing away the broken down dirty residues. A perfect solution for not so easy to reach windows and skylights.
Solar Control Windows: Heat gain and glare have always been a problem
through large windows. Solar control glass used in the windows can drastically reduce the heat build-up in sunny weather without the need for costly air conditioning or blinds. This glass has a microscopically thin coating on one side that reflects up to 2/3 heat from the sun to the outside filtering uncomfortable glare from the sun, keeps interiors cooler whilst letting in lots of natural light.
Photovoltaic Window: New energy technologies are developing the first-of-its
kind Photovoltaic transparent glass for windows, the BIPV (Building-integrated photovoltaic) panels. These are transparent solar panels with tin oxide coating on the inner surface of the glass panes to conduct current out of the cell. The cell contains titanium oxide that is coated with a photoelectric dye. They are increasingly being incorporated into the construction of new buildings as well as retrofitted into old structures as a principal or ancillary source of electrical power. Large fixed windows and skylights are ideal places to for this glass. www.frontale-india.com
