On Fenesta UPVC blend

Vinyl is Unplasticized Poly Vinyl Chloride (UPVC). It is the second most popular plastic in the world, used in food packaging, medical equipment and building products. UPVC is widely used in the West where it is commonly known as Vinyl.
Polyvinyl chloride, commonly abbreviated PVC, is a widely used thermoplastic polymer. It is one of the most valuable products of the chemical industry. Around the world, over 50% of PVC manufactured is used in construction. As a building material, PVC is cheap, durable, and easy to assemble.

Polyvinyl chloride is used in a variety of applications. As a hard plastic, it is used as vinyl siding, magnetic stripe cards, window profiles, gramophone records (which is the source of the term vinyl records), pipe, plumbing and conduit fixtures.

It can be made softer and more flexible by the addition of plasticizers, the most widely-used being phthalates. In this form, it is used in clothing and upholstery, and to make flexible hoses and tubing, flooring, to roofing membranes, and electrical cable insulation.
UPVC or Unplasticized polyvinyl chloride is often used in the building industry as a low-maintenance material, particularly in the UK, and in the United States where it is known as vinyl, or vinyl siding. The material comes in a range of colors and is used as a substitute for painted wood, mostly for window frames and sills. It has many other uses including fascia, and siding or weatherboarding. The same material has almost entirely replaced the use of cast iron for plumbing and drainage, being used for waste pipes, drainpipes, gutters and down pipes.
Fenesta UPVC / vinyl windows have a special 'tropical' formulation for Indian conditions. It does not fade; the sun, rain, wind have no impact. It has these special additives:

  • Heat Stabilizers: To prevent material degradation during extrusion.
  • Impact Modifiers: To improve toughness and impact resistance.
  • UV Stabilizers: Prevents fading under ultra violet rays.
  • Lubricants & Process Aids: To improve the extrusion process.

To make UPVC, Fenesta sources PVC resins from a sister division and monitors its extrusion into profiles at its quality conscious state-of-the-art facility in Kota, Rajasthan.
PVC + Additives + Stabilizers = Fenesta UPVC.

Beware of spurious blends: Some players tend to use cheap blend by not adding enough of additives and stabilizers and using more of chalk.

Profiles made from Fenesta UPVC blend are tested by BIS, UK (amongst the strictest standards in the world) for stability under strong UV radiations.

Fenesta believes in providing long term quality to its customers.
UPVC, a product of natural resources (57% salt and 43% oil), is 100% medically safe. In fact, it is widely used in the manufacture of catheters and blood bags by the medical profession.

It is safe in other ways too. Vinyl windows made from UPVC create a ‘safe’ indoor environment, free from dust and noise pollution. It is safe from the ecological point of view. The manufacture of UPVC requires minimal use of energy, far less than the energy spent in the manufacture of aluminium or steel.
Unlike MOST other plastics UPVC / Vinyl is self-extinguishing. This means when the source of the fire is taken away, it stops burning.

Any material will give off fumes when it burns – but UPVC / Vinyl wont.
Fenesta’s UPVC / vinyl blend uses the highest amount of titanium di oxide; a key ingredient required to maintain the whiteness of windows under harsh UV conditions. This ensures that Fenesta windows do not fade over sustained exposure to sun.
UPVC window systems are resistant to scratches during normal domestic use. If scratches do appear, they can be polished out.
Fenesta has undertaken an accelerated weather testing with BSI, UK that certifies Fenesta for sustained exposure to sun.
Yes they have been tested for many years in the Arizona desert, where the solar and UV radiation is very similar to India.

Common perception is that more number of chambers add to strength of UPVC window. However, more than 90 % of the strength of the window is derived from stell reinforcement.

1 mm increase in the thickness of PVC profile increases the strength by less than 1%.

1 mm increase in thickness of steel increases strength by 40%.
Fenesta windows derive 95% of their strength from reinforcements made of galvanized steel or Aluminum sections. They are used in chambers of the profile to provide the necessary strength to the window members. Separate sealed chambers in profile and zinc coating on steel bestows longevity to the product during usage period.

The thickness and shape of the section is designed to provide the necessary functional and performance parameters of window. The usual thickness varies between 1.0 mm to 3.0mm.

The reinforcements are screwed to the UPVC profile at a designed pitch using self drilling special screws. The unification of the duo renders strength to the windows.
Fenesta UPVC windows have a life of 40 – 50 years. Their life is as much as that of the building.
Fenesta window systems are modular in nature. Each window is made as per the customized size. However, there are some constraints for the maximum height and width of a window which is different for each type of window.
Fenesta has engineered three innovations to keep the rain out:

  • Rain track: An elevated section clipped on the inside track of the window functions like a dam. It captures rainwater and   drains it out
  • Sill arrangement: This special system prevents air pressure from pushing the rainwater indoors. Instead, the rainwater   flows down vertically, at some distance from the outer wall
  • Gradient slope: A track at a downward slope of 5 degrees ensures accumulated rainwater flows out
Fenesta windows are sealed from top to bottom with a combination of double seals, silicon seals between the wall and the window and multiple point locks. This excellent sealing combined with non-conducting properties of UPVC make provides sound insulation.
Wind speeds in India are much higher than those of other parts of the world. Along the coast, in the east and the west, wind speeds touch 200 kmph, the equivalent of 2000 Pascal wind loads.

In these conditions, conventional windows rattle and whistle.

Fenesta engineers an air tight solution to tackle these wind loads: Fenesta Series 3000 windows have broad sections reinforced with steel and further strengthened with a special “Hurricane Bar”. The Hurricane Bar doubles up as a handle. Multiple seals stop air ingress. No more whistling and rattling sounds even at 3000 Pascal wind loads.
Fenesta offers the following types of doors:

  • Slider Doors
  • Casement Doors (Single Sash or Twin Sash)
  • French Doors
Yes, Fenesta windows can accommodate a bug screen/ fly mesh.
Fenesta has gained priceless knowledge of Indian market in the past 5 years. It has designed windows for the relevant wind pressure. Series 1500 is used for wind loads of 1500 Pascals while series 3000 take care of wind loads of 3000 Pascals.

Series 3000 windows owing to their larger strength provide an additional advantage of size. You can now design windows stretching from floor to ceiling and spanning entire balconies. It also leads to a greater design flexibilities.
